What are polyethylene pipe connections?
Polyethylene connections are used in pipelines and facilities in various industries to change the angle of the fluid flow, change the diameter of the pipeline, change the flow rate and connect the pipes to each other. they take
These connections, like polyethylene pipes, are produced and supplied from polyethylene raw materials PE80 and PE100 with different angles and sizes.
These connections can be produced by various methods, including injection or using thick polyethylene sheet with cutting and turning. For making polyethylene joints, each of these methods has advantages and disadvantages. For example, in the injection method, due to the abundance and variety of sizes, types of materials and different pressures, it is not possible to access all these sizes, but in the machining method, based on the connection plan, they can be machined and Matched perfectly with the map.
According to their needs in different projects and applications, polyethylene pipelines are connected by means of various polyethylene connections (electrofusion, welding and screwing). For example, for gas supply projects, electrofusion fittings are used, and for water supply projects, screw fittings are used up to a pressure of 10 atmospheres. For the rest of the projects, polyethylene welding joints are used according to the German DIN16963 standard.

Important Note in Installing Polyethylene Connections
1- It is necessary before installation; The end of the pipe should be cleaned carefully and the parts should be installed according to the specified order. 2- The parts must be placed in their exact place and the necessary work must be done firmly. 3- A special wrench must be used to close the connections. 4- It is better to make polyethylene joints in the same family type so that the fastening is done completely 4- The core that is connected to the connection of polyethylene material is better to be made of plastic material so that the corrosion rate of the connection is reduced and leakage is reduced.
