HDPE FITTINGS

Hebei Shentong Plastic Industry Co., Ltd. is a professional enterprise engaged in the research and development design, production and sales, and pipeline installation of water supply and drainage systems in the fields of buildings and municipal engineering. With years of professional technology and practical application experience, the company mainly focuses on "groove type high-density polyethylene (HDPE) silent drainage system", "flexible socket HDPE silent drainage system", "polypropylene (PP) silent system pipeline system", "flange type reinforced polypropylene (FRPP) silent drainage pipeline system", "flange type flame retardant and high-temperature resistant reinforced polypropylene (FRHT-FRPP) silent drainage pipeline system", "hot melt socket HDPE silent drainage pipeline system", and "same layer drainage pipeline system". The development and application of systems. And undertake relevant construction and installation.

The connection methods for HDPE silent drainage pipes include groove type connection, flange connection, screw pressure cap type socket connection, fixed pressure cap type socket connection, hot melt socket connection, and electric fusion connection.

The connection methods of HDPE double wall corrugated pipes mainly include hot melt connection, electric fusion connection, socket connection, and flange connection.

Hot melt connection is a common connection method, which mainly uses specialized hot melt equipment to heat pipes and fittings to a molten state, then quickly connect them together and form a complete connection after cooling. This connection method has the advantages of high connection strength and good sealing, and is widely used in the connection of HDPE double wall corrugated pipes.

Electric fusion connection is a process where a specialized electric fusion fitting with an embedded resistance wire is in close contact with the connection part of a pipe or fitting, and then the connection part is heated by the embedded resistance wire to melt and connect until the joint cools down. This method does not require specialized equipment, but the connection cost is high, making it suitable for connecting small diameter pipelines.

Socket connection is a connection method where one end of a pipe or fitting is inserted into the other end, usually requiring sealing material to be filled between the socket and the socket to ensure the sealing of the connection. This connection method is easy to construct, but the connection strength is relatively low, making it suitable for connecting low-pressure pipelines.

A flange connection is a connection method in which flanges are installed at both ends of a pipe or fitting, and the two flanges are fastened together by bolts. This connection method has the advantages of high connection strength and easy disassembly, but it has a high construction cost and is suitable for connecting large-diameter pipelines or pipelines that require frequent disassembly.

In summary, there are various connection methods for HDPE double wall corrugated pipes, and the specific selection of which method needs to be comprehensively considered based on the actual situation and needs of the project.
