HDPE reinforced winding pipe has the advantages of corrosion resistance, light weight, easy installation, large flow rate and long life, and can replace pipes made of high energy consumption materials (cement, cast iron, glass fiber reinforced plastic pipe, ceramics, etc.), which is an environmentally friendly green product. So, what is the best connection method for HDPE reinforced spiral wound pipe?

There are many ways to connect HDPE reinforced winding pipes, and the common methods mainly include welding, wire connection and flange connection. In the special system, due to the different requirements of the system for the pipeline, the connection method of the pipeline is also different. For the fire sprinkler pipe, the pipe rust requirements are strict, and the connection method is flange connection in the past, on-site installation, and then secondary galvanizing and reassembly. This method is more cumbersome, and the cost is relatively high, and the requirements for the size and quantity of the blanking material at the initial installation are also extremely strict. In response to this kind of problem, a new installation process has been developed - groove clamp connection, also known as clamp connection technology.

The trough pipe connection system is a process in which the pressure-responsive sealing ring is sleeved into the ends of two connecting steel pipes, the sealing rings are wrapped by two clamps and snapped into the groove of the HDPE winding pipe, and the two round-headed oval neck bolts are tightened to realize the sealing connection of HDPE reinforced winding pipe.

The process flow is as follows: the pipe end is processed into a groove→ the sealing ring is greased→ the sealing ring is sleeved into the pipe end→ close to another pipe section→ the sealing ring is sleeved into the other end→ clamped into the pipe clamp → tighten the bolt. The pipe end machining groove is carried out on a special grooving machine. According to the diameter of the pipe, select the corresponding plus wheel to adjust the corresponding groove depth, and put the pipe end into the machine to press into a standard groove.

In order to easily and quickly insert the sealing ring, the sealing ring should be greased before the ferrule, another section of steel pipe should be inserted into the sealing ring, the clamp should be put on, and the bolt should be tightened, and the whole process was completed. No special technical skills are required for the entire process.
