Electric melting pipe fittings

Electric melting pipe fittings refer to a type of plastic (polyethylene) pipe fittings that can be melted and connected by the temperature generated by an electric current. Gathering together

In the sales and application of ethylene pipeline systems, approximately 15% to 20% of the sales revenue belongs to fittings. Polyethylene pipeline system fittings are mainly divided into two types: hot-melt fittings and electrofusion fittings. Due to price reasons, hot-melt fittings are used more in engineering applications than electrofusion fittings. However, electrofusion fittings play an important and irreplaceable role in engineering and maintenance, especially in construction where they are less affected by external environment and human factors. Therefore, they have better reliability and are more popular among users. Electric fusion fittings are increasingly being used in gas pipeline engineering.

Product performance:

Due to the fact that the base material of the electric melting pipe fittings is PE material, the PE pipeline system composed of PE pipes together solves the two major problems of traditional pipelines: corrosion and leakage at the joints. Its advantages are mainly reflected as follows:

(1) Corrosion resistance: Long service life;

(2) No leakage at the joint; The use of electric fusion fittings for connection essentially ensures the consistency between the interface material, structure, and pipe body of the PE pipeline system, achieving the integration of joints and pipes;

(3) It can effectively resist underground movement and end loads: After the PE pipeline system is connected by fusion welding method, the joints based on this method can withstand end loads without joint leakage. Meanwhile, the stress relaxation characteristics of PE can effectively dissipate stress through deformation, so in most cases, expensive anchoring is not required at joints and bends. Based on its high toughness, the elongation at break generally exceeds 500%, making PE pipeline s
