Types Of Polyethylene Pipe Fittings

It is common in pipe systems to utilize a fitting to join straight segments of pipe or tube, change the form or size of the pipe or tube, and regulate (or measure) fluid flow.

Poly Ethylene pipe fitting is known as a PE pipe fitting. Various mechanical fittings are available to connect PE pipes to pipes made of other materials, such as copper, brass, and stainless steel. Flange connectors or transition couplets can be used to connect the pipes.

What’s the best way to join PE pipes together?

In contrast to PVC and ABS, the poly pipe cannot be assembled with adhesive or solvents. Either heat welding or mechanical joining of the pipe is required.

 How can a PE Pipe Network be put together using various methods?

  1. Electrofusion

This is one of the most used Poly Ethylene pipe fitting methods, known as an EF fitting. The inside section of the fitting is wrapped in copper coils using EF. An electric current is then passed via the coil when both pipes are inserted into the fittings. Fitting and pipe are fused as a result of a melting copper coil caused by an electrical current.

Afterward, the pipes are left to cool,leaving the two pipes from a solid junction. However, the poly electrofusion must be done correctly for it to work. During the joining and cooling process, there should be a good level of contact.

  1. Welding the butt

However, you can also connect the PE fittings by butt welding. A piece of hydraulic clamping equipment is used to sever the two pipes’ ends. Using a hot plate, both ends of the trimmed pipes are heated, and the plates are detached so that the two ends may be forced together, melting them. A high beam is the end consequence of this method of joining. A smooth inner bore can be an issue in this instance. Despite detaching the bead, doing so may cause other issues with the connection.

Your best joint will be made if the connected parts are both clean. There is a greater risk of contamination if the surface is filthy. Allow the pipe to ignite for a sufficient time before welding it together. It is crucial to get assistance from a professional if you like to cope with the bead.

  1. Joints that are compressed

Compression couplings are another option for connecting PE pipes. An O-Ring is used to push the pope firm into the O-Ring technique. The grip is tightened even further after the treatment using the compression ring. The EPMD O-Ring is the ideal material to use for the fitting.

The compression procedure is easy and does not necessitate the services of a specialist.

  1. Melting hot

Hot-melt connections could be used to connect poly pipes and fittings. Generally, hot-melt sockets and butt joints are only suitable for connecting pipes with nominal diameters of less than 63mm. On the other hand, polyethylene pipes and fittings should never be linked using thread.
