Hydraulic fittings are designed and constructed to resist high-pressure leakage and sudden failure. The diverter tee is designed to allow flow to continue in the main line, even when the side branch is shut down and not calling for heat. Diverter tees have directional markings which must be heeded; a tee installed backwards will function very poorly.

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.

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.

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 .

We offer more detailed information about NPT pipe threads here. Choose from our extensive range of plumbing pipes and fittings including the pushfit system of valves and connectors, as well as brass and copper compression fittings. Whether you’re on-site or fitting piping domestically we have only the best plumbing and pipe fittings, in numerous pack sizes for you to use. Various types of pipe fittings are available in plumbing systems for different purposes and functions. A pipe fitting is used in plumbing system to join multiple pipes of same size or different sizes, to regulate the flow or to measure the flow.

Our goal is to help make purchasing quick with fewer shipping costs and less time spent scouring the web for the pipe fittings you need. Tee type fitting is a component of plumbing system which is in T-shape. It is having one inlet and two outlets, outlets are arranged at 90o to the main line connection . It can also be used to combine the flow from two inlets to one outlet. They are also available in different materials and different sizes.

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.

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.

PTFE tape and pipe joint compound (also known as “pipe dope”) should only be used on “IPS” (“iron pipe size”) threads, which are normal pipe threads. IPS threads make their seal along the threads themselves; when a piece of IPS-threaded pipe is screwed into a fitting, PTFE tape and/or pipe dope is used to assist that seal on the threads. Flare fittings, on the other hand, seal on the beveled ends of the fittings, and so using pipe dope or tape on flare threads could actually prevent the fittings from making an adequate seal. The chief advantage of these connectors is that they can be installed after cutting the pipe to length in the field. This can save time and considerable expense compared to flange connections, which must be factory- or field-welded to pipe segments. However, mechanically fastened joints are sensitive to residual and thickness stresses caused by dissimilar metals and temperature changes.

This instruction describes the pre-assembly of a cutting ring (SRD…VA) on the stainless steel pipe in the assembly stud and the finishing assembly of the cutting ring in the screw sleeve. Manufacturers such as Victaulic and Grinnell produce sleeve-clamp fittings which are replacing many flange connections. They attach to the end of a pipe segment via circumferential grooves pressed around the end of the pipe to be joined. They are widely used on larger steel pipes, and can also be used with other materials.

There are two types of Tee used in piping, Equal / Straight Tee, and Reducing / Unequal Tee. 45 Degree elbow is installed between the pipe to change the direction of the pipe by 45 Degree. Tighten union nut about 1/2 turn, bracing the screw sleeve with a spanner. Tighten union nut 1/4 turns, bracing the screw sleeve with a spanner. Disassemble the pipe and check that a clearly visible shoulder of cut material is present in front of the rst cutting edge.

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.

Wye tee allows one pipe to be joined to another at a 45° angle. This type of tee reduces friction and turbulence that could hamper the flow. A barred tee which is also known as a scrapper tee is used in pipelines that are pigged. The branch of the tee has a restriction bar welded internally to prevent the pig or scrapper to enter the branch. The bars are welded in the branch in a way that it will allow restriction free passage of the pig from the run pipe.

Socket weld and Threaded Pipe Fittings are forged products and classified based on their pressure-temperature rating. These fittings are available in four pressure-temperature rating class. It used to connect pipe to pipe or pipe to swage or nipple. Click the spin controls to enter number of pipe fittings for each pipe section.

The joint is then heated, typically by using a propane or MAPP gas torch, although electrically heated soldering tools are sometimes used. Once the fitting and pipe have reached sufficient temperature, solder is applied to the heated joint, and the molten solder is drawn into the joint by capillary action as the flux vaporizes. “Sweating” is a term sometimes used to describe the soldering of pipe joints. Assembling threaded pipe is labor-intensive, and requires skill and planning to allow lengths of pipe to be screwed together in sequence. Most threaded-pipe systems require the use of strategically located pipe-union fittings in final assembly. Threaded pipe is heavy, and requires adequate attachment to support its weight.

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.

Unlike metal welding, solvent welding is relatively easy to perform . Solvents typically used for plastics are usually toxic and may be carcinogenic and flammable, requiring adequate ventilation. In drainage systems, it is primarily used to connect horizontal drains to vertical drains. The center connection is generally to the pipe leading to a trap . It must not connect a vertical drain to a horizontal drain, because of the likelihood that solids will accumulate at the bottom of the junction and cause a blockage.
