Fittings for central vacuum systems are similar to DWV fittings, but are usually of thinner and lighter construction because the weight of the materials conveyed is less. Vacuum-system designs share with DWV designs the need to eliminate internal ridges, burrs, sharp turns, or other obstructions which might create clogs. Non-return or check valves allow free flow of a fluid in one direction, but prevent its flow in a reverse direction. They are often seen in drainage or sewage systems, but may also be used in pressurized systems. Isolation valves are used to temporarily disconnect part of a piping system, to allow maintenance or repair, for example.

The use of miter bend is restricted to the low-pressure water line. Applications include rotary and pipe fittings, adapters and couplings, hydraulic pipes and high pressure flanges. Whether you’re simply stocking up on plumbing fittings and repair parts or have a specific project in mind, Ace offers many types of pipe fittings made of different materials. Find your plumbing fitting solutions at Ace, then shop for other essential plumbing repair parts for your home needs. Coupling are also useful if the pipe is broken or leakage occurs.

A threaded pipe has a screw thread at one or both ends for assembly. Crosses, also known as four-way fittings or cross branch lines, have one inlet and three outlets , and often have solvent-welded socket or female-threaded ends. Cross fittings may stress pipes as temperatures change, because they are at the center of four connection points.

Isolation valves are typically left in either a fully open or fully closed position. A given isolation valve may be in place for many years without being operated, but must be designed to be readily operable whenever needed, including emergency use. Since the alignment stop is missing, it is up to the installer to carefully measure the final location of the slip coupling to ensure that it is located correctly. If there’s a pipe needing cut or bent, we have the equipment to help make it happen.

They are made up of different materials like copper, iron, brass, PVC etc. Flange fittings are generally used for connections to valves, inline instruments or equipment nozzles. Two surfaces are joined tightly together with threaded bolts, wedges, clamps, or other means of applying high compressive force. Although a gasket, packing, or O-ring may be installed between the flanges to prevent leakage, it is sometimes possible to use only a special grease or nothing at all . Although flange fittings are bulky, they perform well in demanding applications such as large water supply networks and hydroelectric systems. Elbows are used to change the direction of flow between two pipes.

Cutting rings with elasto- mer seal work according to the same functional principle, but they are furnished with additional elastomer seals to increase operating reliability further still. “Ordering was flawless, website straight to the point, shipping was quick and as stated, product was exactly as ordered.” Log in to TheConstructor to ask questions, answer people’s questions, write articles & connect with other people.

Short radius elbows are used under limited space applications. However, it has a high-pressure drop due to a sudden change in the direction of flow. The 90 reducing elbow is designed to change direction as well as reduce the size of the pipe within a piping system. The reducing elbow eliminates one pipe fitting and reduces the welding by more than one-third. Also, the gradual reduction in diameter throughout the arc of the reducing elbow provides lower resistance to flow and reduces the effect of stream turbulence and potential internal erosion. These features prevent sizeable pressure drops in the line.
