Unlike metal welding, solvent welding is relatively easy to perform

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.

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 used to connect pipework together and form angles. Plumbing fittings come in various different types to reduce the flow size from larger to smaller or to change the direction of flow between two pieces of pipework. Choose from metal or plastic fittings and various pack sizes.

It is like a concentric reducer that maintains a centerline of the pipe but small in size. A pipe tee is used for distributing or collecting the fluid from the run pipe. It is a short piece of pipe with a 90-degree branch at the center.

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 .

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.

Depending on the connection technology and application, basic skills may be sufficient, or specialized skills and professional licensure may be legally required. This fitting differs from a standard cross in that two of the ports have curved inlets. 9000 class fittings are available in only the socket weld type. There are two types of the reducer used in piping Concentric & Eccentric. Generally, crosses are not used in process piping to transport fluid. But forged crosses are common in the firewater sprinkler line.

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.

A specially shaped limit ridge prevents overtightening, the pipe material that is raised in front of the edges is cold-hardened.

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.
