Millions of gallons of hydraulic fluid are wasted each year, mostly due to system leaks. Place lock washers on bolts and insert through clamp halves. Hoses, tubing and fittings are the critical elements of all hydraulic systems. The wrong fitting style, material or installation can cause catastrophic system failure and even become a safety issue. Hydraulic hose fittings are used in custom hose assemblies to join hydraulic hoses to pipe, equipment, and other hoses. You can also measure from fitting collar end to fitting collar end to get the cut-off length. In the design of process equipment hydraulics, the goals are to reduce or eliminate frictional losses in transfer lines and equipment, promote optimal operating conditions and increase service life of the system. Angled fittings measure from the center of sealing surfaces. Yet, some manufacturers may have their own codes, so take your own measurements if you are unsure. You cant tell the I.D. Copyright 2021 Top Dog Repairs. Flange connections are frequently found in injection molding machinery, chemical processing and food and beverage processing. Overall length (OAL) is the actual length of the assembly from end to end. CIP refers to the cleaning of tubing, pipes, filters, fittings and the entire interior of process equipment without disassembly. Measuring the length of a hose includes hydraulic hose fittings. Hydraulics, How To, You can contact us here, or alternatively connect with us on social media. All rights reserved. If you buy a hose too large, it may not fit hydraulic hose couplings, and it has a good chance of leaking and not delivering the correct pressure to hydraulic components. A hose is a flexible, reinforced rubber or thermoplastic conduit that is used to convey fluid within a hydraulic or process system. The proper selection of hose and tubing size, material and configuration along with the correct fittings and flanges is imperative in the design of all processing equipment. The flow rate (expressed as gallons per minute or liters per minute) or velocity (expressed as feet per second or meters per second) of the fluid moving within the system is the key to understand when sizing the hose for proper performance. Fitting selection comes down to a popular and well-known acronym dictated by the systems requirements. One of the most fundamental considerations when selecting hose is sizing. Even if youre experienced in the field, its a good idea to consult with a manufacturing technician to get the best tools for your project. Volume is the amount of fluid flow per unit time and is typically measured in gallons per minute (GPM), while velocity is the distance that a fluid travels per unit time, measured as feet per second. You may see a number like -5. Flanged and female threads take measurements starting at the sealing surface of the fittings. Before his 10 years with Motion Industries, Joe spent 20 years with Monroe Rubber and Plastics Supply Company (now a unit of Motion Industries), with the last 10 as President/Owner. Selecting the wrong hose for your custom equipment can cause system failure and unnecessary expenses, but a professional consultation can ensure the best possible outcome. Too much flowrate by the hose being too small of ID can cause inconsistency, internal damage, and fluid leaks, while too large of hose can compromise the systems response output. Most food and beverage operations are continuously producing large volumes of product. Required fields are marked *. Do not guess because you need an exact fit for hydraulic hose fittings and hydraulic hose couplings. 64 Sarasota Center Blvd, Sarasota, FL 34240. Additionally, the costs of the larger hose assembly and connections may be higher than actually needed. Access My Account, Order History, Lists and more here. When selecting your ends or couplings, consider the size, material, and application. Measure the inside diameter. This opens the hose inner tube to allow easier entry of the threaded insert. Some hoses may have sizes like 5/8 or 1/2 printed, but the industry standard uses dashes. The most important thing to remember when sizing hoses is the inside diameter or the I.D. The metric nominal equivalent may also be referenced as well, but keep in mind that this just a reference in most cases. The outer diameter (O.D.) beverages) requires a stainless steel tube and fittings that are stationary. They can help you with hoses, couplings, hydraulic assemblies, and hydraulic hose accessories. When you need assistance, contact your hydraulic hose supplier. New Vice President/General Manager, Power Transmission & Fluid Power, Americas. STAMPED: E for the Ends (i.e., couplings) and D for Delivery (i.e., volume and velocity). Stainless steel hydraulic fittings are best for food and beverage processing applications, while hydraulic fracking (which carries hydrochloric acid, oil and water) requires special high-pressure hydraulic hose assemblies. You should therefore consider the hose length when calculating system pressure requirements. Then there is the choice of the proper fitting connection. For example, a 3/4 measured hose ID will be designated as either a 3/4 or in terms of decimal size .75. Lubricate the threads of the insert and thread it into the socket until the two pieces are flush together. Going slightly larger ID will reduce the pressure loss (also known as pressure drop). Consult Jason for more information. system, which stands for size, temperature, media, pressure, ends, and delivery. Top subscription boxes right to your door, 1996-2022, Amazon.com, Inc. or its affiliates. Shop products from small business brands sold in Amazons store. This can lead to damage of seals, clogged pumps, valves, and filters as well as failure of the hose itself. Were here to help. Discrete manufacturing is the process for making items as simple as nuts and bolts, to complex items such as automobiles and computers. Normally, if the hose is to be used as a replacement of an existing hose, replacing with the same type/rating of hose is a good choice for similar durability and performance expectations. With options abounding and a true ability to do it yourself, we can help you save costs and, Use the Right Adapters and Fittings on Your Hydraulic Hoses, Tapered pipe of the following sizes should be tightened. When replacing hoses and hydraulic assemblies, you should consider several things, and the most critical part of hose selection is getting the correct size. Hydraulic Systems, These systems can be many thousands of feet underwater and weigh up to 1,000 tons each. For the compatible fitting, as with hose and tubing, there are a number of important factors to consider, including: Additionally, consider whether an elastomeric seal is to be used, such as an O-ring or gasket. Typical information includes the manufacturer, part number, size, pressure ratings, industry-standard rating, and a date code that tells you when the hose was manufactured. Let us know what we can do to keep you operating smoothly. These are key considerations when selecting hose or tubing material and length, as well as wall thickness and burst pressure rating. A wide variety of materials can be conveyed using hoses, so you must consider the potential for physical or chemical reactivity between the fluid medium and the hose material. Place the socket/shell in a vise (if available). The losses due to equipment failures for food manufacturers can be significant not just from loss of production time, but often the impact of food or drink ingredient spoilage can be a major portion of downtime losses. Hydraulic hose caps and plugs seal and protect the ends of hydraulic hoses to keep out dust, dirt, and other contaminants. Hose, But not matching it to the compatible fitting that is specific to the application will only increase the chances of system failure. A 1 ID would be 16/16 or a -16, and so on. If the hose is too small of inside diameter, pressure losses could be high and excessive flow-rate will create heat which leads to damaging the hose inner tube and possibly creating flow erosion of the hoses tube. In process manufacturing, goods are produced by combining ingredients, raw substances and supplies, using formulas or recipes such as in the food and beverage, chemical, petroleum and pharmaceutical industries. The O-ring material selection is dependent on the factors mentioned above, particularly chemical compatibility of the media being transferred and system pressure. To determine the cut-off length, measure from the end of the fitting to the end of the fitting collar. In many process applications especially food and pharmaceuticals sanitary lines and fittings must be used whenever the system is carrying product (media) that cannot be contaminated by bacteria. They transmit fluid from the pump to valves, actuators and motors, and generate the force and motion to make the system work. Many hoses are custom-built assemblies made to meet specifications for a prescribed application need. Extended service life, plus reduced maintenance and downtime are largely driven by proper hose, tubing and fitting selection. The system is only as good as the compatibility of the fitting and hose or tubing. For hose and tubing, first understand the compatibility of the fluid that is to be transferred with the material of the hose or tube and its required pressure. Scott has spent the majority of his career building relationships and adding value to key customers around the globe. Flange connections are often used in applications that will encounter exceptionally high pressures in larger diameter tubing or piping. Regardless of pressure, it is also important to consider flanges where there may be a need to disassemble the connection for easy access to modify, clean or inspect the system. Proper selection of the hose or tubing is crucial. The cost of fluid loss itself can be tens of thousands of dollars from one system. Want to Be a Jason Hydraulic Distributor? Careful consideration of the specific application must be made to assure the hose is properly selected for best durability and safety. Male threads measure from the thread ends. A 30-year hose industry veteran, Joe Lark is Motion Industries' Product Manager for Hose. For industrial hoses, it is most common to see the size in direct terms of the inch size. Attachment (i.e., a crimped hydraulic fitting for a hose, and a compression fitting for tubing), Fitting configuration (straight, elbow, tee, etc. Subtract these two measurements from the OAL. Some hoses are thicker and have more layers than others, and sizing must be exact. You can find this number on the layline or cut the hose and measure the I.D. Whether you need special packaging, unique shipping, certification, testing, or tagging, Jason Industrial will help you get the product you need, when you need it.

Hydraulic Hoses: Buying the Right Size Hose. Note that as indicated in the nomograph, hoses used for suction (pump intake) must be sized larger than those for the output side of the pressure (pump outlet). Some materials contract, expand, or fail when exposed to high or low temperatures and thermal fluctuation. From chemical processing to oil and gas processing to food and beverage processing, the correct selection of hydraulic components is critical to the change in pressure, safety and service life of the system. can be used to ensure the hose fits within the allotted space, it has no direct impact on pressure loss and flow calculations within systems. Even stainless steel can harbor bacteria in microscopic peaks and valleys in the surface finish. In addition, the impact of downtime due to component failure can be costly. Most sanitary system components are made of specific stainless steel alloys. Fluid leaks can also cause equipment damage because of loss of lubrication, which creates premature wear and system failure. Hydraulic fracking hose assemblies may have fittings and flanges made of carbon steel, stainless, Hastelloy, Monel, Duplex or other alloys. When a system goes offline due to any kind of failure, it causes unplanned downtime and production output is lost, resulting in what can be a significant loss of revenue and an increased cost of maintenance and repair. The maximum system flow rate is determined primarily from the ratings of the pump used. Jason Industrial at Perumin Mining Convention 2022. Hose sizes are designated based on the inner diameter of the hose, which is the measurement of the straight distance between the two furthest points on the inner surface of the tube. Quality Products, Torque bolts in a diagonal sequence in small increments to the torque levels listed in the table below. Critical components in O-ring face seal fittings and most flange assemblies are an elastomeric seal. Tags: Each of these individual design considerations must be compatible with each other prior to the total system design. As required by the Food and Drug Administration, sanitary or hygienic fittings and tubing must be cleanable, either manually or by clean-in-place (CIP) processes. If the hose is too large of inside diameter, the volume of fluid contained will be greater than needed for function of the equipment and routing of the hose may be difficult. Save my name, email, and website in this browser for the next time I comment. Fittings come in a dizzying variety of styles, orientations, and attachment methods to meet the particular needs of every system. http://www.facebook.com/ProcessingMagazine, https://www.linkedin.com/showcase/27062974, Photo 125578758 Nostal6ie | Dreamstime.com, Software solves the tedious process of verifying data on multiple diagrams and drawings, Hose safety for food and beverage processing, Reliable pipes for aggressive chemicals when ECTFE is safer than PFA, Case Study: PVDF pipeline for fructose transportation. Each of these five considerations must be taken into account for accurate system design and configuration. Your hydraulic hose will need to withstand the working pressure of the application, as well as any additional pressure that could be caused by fluctuations within the system. Most leaks and system failures are not due to inferior components, but primarily due to incorrect selection of components or improper installation. The hose size must also take into account the maximum distance between the two end points of the hose. There are notable exceptions to this designation namely SAE 100R5, 100R14, and certain other hoses used in airbrake and refrigerant applications. It runs the entire hose length and repeats itself. Cut length is from the fitting collar end to fitting collar end. There are several types of adapters, but each of them has specific, important guidelines to follow when it comes to tightening. Maximum amount of digits: 6. Accurate hose sizing requires a combination of complex calculations and industry knowledge. All rights reserved. Processing systems in any application or market can be very complex, critical or sensitive. Hydraulic hose fittings and couplings are parts that connect hydraulic hoses in a pipe system. Is it Time to replace your Hydraulic Hoses? Hose size is determined by inside diameter. Therefore, sanitary fittings are specially polished to reduce, or sometimes completely remove, this surface roughness. Then turn the hose -to-1-turn clockwise. The most common flange sizes range from -2 inches, and in processing systems they are SAE O-ring flange code 61 or 62. Every character on the line gives you information about the hose. Now, you are ready to learn about hose fittings and adapters. Consider subsea separators and processing units, which include many different processes, such as single- and multi-phase boosting of well fluids, sand and solid separation, subsea water removal and gas or liquid separation. of the hose includes the entire cross-section of the hose. STAMP: Size, Temperature, Application, Media and Pressure. As hose length increases, so does the friction losses between the fluid and the inner surface of the hose, which reduces pressure inside the system. Pump data may be found on the pump manufacture tag, system specifications or from the pump manufacturers catalog or website. Most hoses used in North America are designated in inches of ID. The couplings are obviously the fitting selection, and the compatibility of media volume and velocity are highly important to a process system. Although the O.D.
