Understanding Common Methods for Joining Pe Pipes and Pe Fittings

When it comes to the installations of pipes and tubes, the right kid of pipe connector fittings makes a significant difference in securing the pipes and preventing leaks and damage. The correct pipe fittings and joints also ensure the structure integrity of the entire network. There are many types of plastic pipes available with PVC distributors and it is important to choose fittings of the same material as the pipe or a compatible material and method. When it comes to Polyethylene or PE pipes, there are a number of PE fittings available which can be used to join the pipes using different methods. Let us understand the common methods for joining PE pipes and fittings:

1.Generally, PE pipes and fittings are joined through the method of heat fusion, one of which is the butt fusion method. In this method, the two PE pipe ends are heated to the desired temperature and are then put together with the action of force. This type of joint can also be used for pipes with different wall thickness.

2.Another heat fusion method for joining PE pipes is saddle or conventional fusion. In this method, a saddle fusion machine is required which connects the two pipes. The pipes to be connected and the saddle fitting are both heated and fused together.

3.The socket fusion method for joining PE pipes is also a heat fusion method. In this, both the internal and the external surface of the PE pipe are heated and the pipe to be inserted is fixed and kept in place until the joint cools and the pipes are joined together.

4.In the category of mechanical couplings, there are several types of fittings available which need to be chosen for the particular function they serve. The most common type of PE fittings are mechanical compressor fittings which come with threaded compression nuts and elastomer grip rings which secure the joints. One can also choose stab type mechanical fittings and bolt fittings, with the latter being used for joining PE pipes with steel or PE pipes.
