Definition - What does Pipe Joints mean?
Pipe joints are integral to any piping system because it is not possible to have a continuous length of pipe for a pipe network. These joints can make or break a pipeline system depending on the resulting durability of the technique used to form the joint.
There are different materials of pipes used in the pipeline industry depending on the need and the type of product that will be conveyed through the pipe.
Trenchlesspedia explains Pipe Joints
There are different methods used to join pipes depending on the material of the pipe.
- Threaded pipe joints are used to join cast iron (CI), galvanized iron (GI), polyvinyl chloride (PVC), copper pipes etc. and are connected by screwing the threads provided externally and internally on either side in each pipe and are suitable for low temperature and low flow conditions.
- Brazing and solder pipe jointing are done on copper or copper alloy pipes by using molten filler material. For same diameter pipes, butt welding is used to join the pipes and gives high strength to resist high pressure.
- Socket welded joints are used to join pipes of differing diameter and where chances of leakage are high.
- Flanged joints are connected using two flanges secured with bolts and are used for large diameter pipes with high-pressure flows.
- Polyethylene (PE) pipes are joined to each other by heat fusion or mechanical fittings.
