Pipe & Fittings

Quality GroovJoint fittings carry approvals by UL, ULC, and NSF-61. Flexible fittings may also be used to reduce transmission of vibration into the DWV system. Although the fittings are not cheap, they are reasonably durable .

Other one is eccentric reducer which is having one edge parallel to connecting pipe due to which air accumulation is not possible. Slip-joint fittings are frequently used in kitchen, bathroom and tub drainage systems. They include a detached slip nut and slip-joint washer; the washer is made of rubber or nylon.

Long elbows are used in low-pressure gravity-fed systems and other applications where low turbulence and minimum deposition of entrained solids are of concern. They are available in acrylonitrile butadiene styrene , polyvinyl chloride , chlorinated polyvinyl chloride , and copper, and are used in DWV systems, sewage, and central vacuum systems. This section discusses fittings primarily used in pressurized piping systems, though there is some overlap with fittings for low-pressure or non-pressurized systems. Specialized fittings for the latter setups are discussed in the next major subsection.

Push-to-pull fittings are a type of easily removed compression fitting that allows pipes to be connected with minimal use of tools. These fittings are similar to regular compression fittings, but use an O-ring for sealing and a grip ring to hold the pipe. The main advantage is that it can easily be removed and re-used, it is easy to assemble, and the joints are still rotatable even after assembly. The pipe end should be square so it sits against the stop in the fittings and does not create turbulence, and needs to be a clean cut to avoid damaging the O-ring during insertion.

This view looking upwards through a hole in the ceiling shows a traditional leaded hub joint and a more recent rubber-sleeved hubless connection . There are similar fittings for both sweat and solvent joinery. Since they are not “tapped” , they are simply called reducing bushings. 3000 & 6000 class fittings are available in both Threaded and Socket Weld types.

Male adapters contain male threads and female adapters contains female threads. One end of adapter is plain which is glued or welded or soldered to the plain pipe end. These are connected when there are 4 pipes are meeting at a point. These fittings generate more amount of stress on pipe as the temperature changes, because they are located at the center of four connection points. Cross fittings are generally used for fire sprinkler systems.

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.

Take a look at our comprehensive ranges for effective plumbing and Gas Safe installation below. The information on those websites is not provided by Steel & Tube. Tighten the union nut until the point at which it becomes noticeably more di cult to turn the union nut. At this point, for example, minor damage on the thread caused by the union nut getting caught must be overcome.

McAlpine valves, such as the McAlpine VP50P air admittance valve, features a dual-fit synthetic rubber finger seal for 3” or 4” soil pipe. Direct the flow of water outside a property with overflow pipes. Our range of PVC overflow pipes are available to buy in 30m, in either black or white. Aquaflow pipes come in a variety of sizes and shapes to complement the property design.

A galvanized coating of metallic zinc was often used to protect steel water pipes from corrosion, but this protective coating eventually would dissolve away, exposing the iron to deterioration. Pipes used to convey fuel gas are often made of “black iron”, which has been chemically treated to reduce corrosion, but this treatment does not resist erosion from flowing water. Hydraulic systems use high fluid pressure, such as the hydraulic actuators for bulldozers and backhoes. Their hydraulic fittings are designed and rated for much greater pressure than that experienced in general piping systems, and they are generally not compatible with those used in plumbing.

Above a certain velocity, the laminar ow of the oil becomes a turbulent ow. Turbulent flows lead to greater heat generation in the system, with consequential losses of pressure and performance.
