PE pipe is manufactured in sizes ranging from 16mm to 2000mm and can be jointed using a variety of techniques and fittings systems.

Puhui Industry carries a huge selection of polyethylene pipes and fittings.  Polyethylene(HDPE) pipe and fittings are for industrial applications involving corrosive media. We offer both threaded and mechanically joined fittings.


PE Fittings

Compression fittings are mechanical accessories that can be quickly and simply installed in many applications and can be easily dismantled.

Special gas compression fittings (yellow) are also available for mesh systems.

There are also a range of threaded fittings for mechanically tapped saddles for metric and PE pipes as well as valves for a variety of applications.Puhui's patented fusion joint system is the world's leading, consisting of 16mm to 2000mm joints. The range includes couplers, elbows, tees, transition fittings and tapped saddles.

PE pipe connection methods

Polyethylene pipes and pipes, pipes and PE pipes, pipes and fittings, and connection between polyethylene pipes and metal pipes, there are many different connection methods with their own advantages and limitations, User can select the appropriate connection methods, depending on the diameter of the pipes, working pressures, places of using, etc. The most common connection methods for polyethylene pipes in urban water supply are: hot-melt connection, fused connection, socket-type flexible connection, flange connection, and steel-plastic transition joint connection.

Connecting methods:

1. Hot -melt connection: Melt PE pipes through special heating tool. Remove heating tools, press the two melting end faces together and keep this pressure until it cools down. Hot -melt connection includes butt fusion, socket fusion, and hot-melt saddle connection.

2. Electrofusion: this connection uses special fittings with electric resistance wire inside that sticks with PE pipes or fittings. PE pipes  heat and fuse through the embedded resistance wire. Cools down naturally. The fusion connection is divided into socket fusion and  saddle fusion.

3. Flexible socket connection: The socket connection is a new method, based on the principle of socket connection of cast iron pipes and polyvinyl chloride pipes (PVC-U). It uses special socket, that inserts PE pipes directly into other pipes or fittings, then compress the anti-pulling or seal the rubber sealing ring to connect them.

4. Flange connection: flange is composed of PE flange connection, steel or aluminum loose flange, gasket or seal ring, bolt, nut, and so on. Flange connection is achieved by tightening the bolts and nuts.

 5. steel plastic transition joint connection: The steel-plastic transition joints connection uses a steel-plastic transition joint prepared by cold pressing or other methods to connect the polyethylene pipes and metal pipe. Steel-plastic transition joints have anti-pull locking rings and seal rings, which usually require good sealing performance and resistance to pull-out, and the pressure resistance are required to be better than the polyethylene pipes in the system.

Above are all connection methods of PE pipes. It should be noted that it is forbidden to make pipe threads directly on PE pipes and pipe fittings. It is forbidden to use open fire to bake polyethylene pipes and pipe fittings to connect directly.

Today, the connection technology of polyethylene pipes has been very mature and reliable. 


These pipes offer superior flow characteristics while retaining their lightweight and flexible properties.

1. Healthy and non-toxic, bacteriological neutral

2. Resistant to high temperature, good impact strength

3. Excellent heat-insulation property from minimum thermal conductivity

4. Light weight, convenient to transport and handle, good for labor-saving

5. Smooth inner walls reduce pressure loss and increase flow speed

6. Light colors and excellent design ensure suitability for both exposed and hidden installation

7. Recyclable, environment-friendly, accords with GB/T standards
