HDPE fittings are widely used in municipal water supply, gas pipelines, the chemical industry, coal, and other industries. In order to meet the requirements of different scenarios, HDPE compression joints are required to connect the pipes. Next, IFAN will introduce the production process of HDPE compression joints and how to connect them.IFAN Facebook Website:www.facebook.com,IFAN factory has 30+ years manufacture experience supporting color /size customization support Free Samples.

Production Process

1. Preparation of raw materials

The production process of HDPE compression joints takes the preparation of raw materials as the first step. High-density polyethylene is the main raw material for making HDPE compression joints. In the production process, high-quality polyethylene raw materials need purchasing from raw material suppliers.

2. Processing and manufacturing

During the processing and manufacturing of HDPE compression joints, it is necessary to add polypropylene raw materials to the injection molding machine, and form molds for pipe parts after heating and melting. Molds professionally ground and cut to create complete HDPE compression fittings.

3. Inspection and testing

The finished HDPE compression joints need to be quality checked and tested. Strict inspection and testing are carried out on the structure, size, pressure resistance, and other aspects of the compression joints to ensure that high quality and high efficiency can be achieved during use.

Connection Method

HDPE compression joint is a commonly used connection method, which can be used to connect HDPE bellows and other types of pipes. The following describes the connection method of HDPE compression joints.

1. Preparation

Before connecting, check whether the size and material of the pipe and joint match and confirm that the size of the joint is consistent with the outer diameter of the pipe. Before connecting, it is also necessary to clean the pipes and joints to ensure that there are no impurities such as dust and oil stains.

2. Connection process

Insert the pipe into the fitting, making sure that the insertion depth is as specified. Then tighten the nut. Before tightening, a layer of sealant needs applied.

3. Test

After the connection completes, it needs to tests to ensure the tightness and pressure resistance of the connection. When performing a pressure test, it is necessary to gradually increase the pressure to check whether there is leakage at the connection and whether the tightening state is good.


The production process and connection method of HDPE compression joints are very critical. If the production and connection are not timely, leakage and rupture will occur, resulting in unnecessary losses. In order for HDPE compression joints used normally, recommended to follow the correct connection method to ensure that the joint structure completes and the connection firms.
