Throttling valves are used to control the amount or pressure of a fluid allowed to pass through, and are designed to withstand the stress and wear caused by this type of operation. A double-tapped bushing is a fitting which serves as a reducer. It is a sleeve similar to a close nipple, but is threaded on both its inner and outer circumferences. Like a reducer, a double-tapped bushing has two threads of different sizes.
The ends may be machined for butt welding, threaded , or socketed. When the ends differ in size, it is known as a reducing elbow. From dependable compression fittings to soldier rings and press-fit elbows, our range of pipe fittings helps make sure you can finish the job properly.
They can be tted either into the screwed joint or into specially made devices. In either case the cutting ring and its edges are moved axially as the union nut is tightened. 900#, 1500#, and 2500# stainless steel flanges are available. Call or email us for those or any custom stainless steel flanges. 18″, 24″, 36″, and 48″ lengths are stocked in addition to the standard stainless steel nipples.
Lightly lubricate the thread and cone of the assembly stud and the thread of the union nut. However, the O-ring must be removed before welding, and any stray welding material must be removed from the O-ring groove and the fitting hole. Plug is a component of plumbing component which is generally used to close pipe opening during inspections and repairs. In use, the spigot of one segment was placed into the socket of the preceding one and a ring of oakum was forced down into the joint with a caulking iron. Ideally, this would be done by pouring in molten lead, allowing it to set, and hammering it tightly with a caulking tool. If this was not possible due to position or some other constraint, the joint could alternatively be filled with lead wool or rope, which was forcibly compacted one layer at a time.
Pipe welding is often performed by specially licensed workers whose skills are retested periodically. For critical applications, every joint is tested with nondestructive methods. Because of the skills required, welded pipe joints are usually restricted to high-performance applications such as shipbuilding, and in chemical and nuclear reactors. Although they are usually used to attach pipe and fittings to mechanical supports in buildings, they do not connect the pipes to each other.
Union is a type of fitting, which functions as similar to coupling. But coupling cannot be removed after fixing but in this case we can remove the union whenever we needed. Although compression connections are less durable than soldered connections, they are easy to install with simple tools. However, they take longer to install than soldered joints and sometimes require re-tightening to stop slow leaks which may develop over time. Because of this possible leakage, they are generally restricted to accessible locations , and are prohibited in concealed locations such as the interiors of walls.
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.
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.
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.
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.
