HDPE fire fighting pipe

    Fire HDPE pipe, also known as fire polyethylene pipe, It is a specialized firefighting pipeline made of high-density polyethylene (HDPE) material. This type of pipeline plays a crucial role in fire protection systems due to its unique performance characteristics. It is made with high density polyethylene (HDPE) as raw material by plastic extruder, especially suitable for acid and alkali resistance, corrosion resistance environment. Fire fighting HDPE pipe fittings adopts hot melting and melting connection, realize the integration of interface and pipe, and can effectively resist the annular stress and axial impact stress generated by internal pressure.

    Fire HDPE pipe has excellent corrosion resistance, and can resist the erosion of many chemicals, ensuring that it will not be damaged by corrosion during long-term use. without anticorrosion treatment, long service life, the minimum life of 50 years. At the same time, it also has excellent impact resistance, can withstand a large external impact, to ensure that it will not rupture or leakage in case of emergency.

    In addition, the internal wall of fire HDPE water pipe is smooth and the fluid resistance is small, which can ensure the rapid supply of fire water source and effectively respond to emergencies such as fire. Its lightweight characteristics also make the installation process more simple and fast, reduce the construction difficulty and cost.

Fire HDPE pipe Specifications and standards:

• The specifications of fire HDPE pipes are diverse, and suitable pipe diameters and wall thicknesses can be selected according to specific needs.
• The length of the pipeline is generally 6 meters or 4 meters. According to the different diameter and working pressure of the pipeline, the national standard specifies the corresponding minimum wall thickness.

Connection

• Hot melt connection: This is a commonly used connection method that involves heating the end faces of HDPE pipe and fittings to a softened state, then quickly connecting and maintaining until they cool and solidify. This method is suitable for HDPE pipes with larger diameters and has advantages such as high connection strength, good sealing performance, and high tensile strength.
• Electric fusion connection: a method of connecting HDPE pipe together using specially made electric fusion fittings. Firstly, certain electric fusion threads are machined at both ends of the pipeline. Then, the electric fusion fittings are inserted into both ends of the pipeline and heated to melt and fuse the materials inside the hdpe pipe and fittings. After cooling, a connection is formed.

• Steel lined PPR pipe: This type of pipe has better performance than HDPE pipe in all aspects.
• PVC pipe: Although PVC pipes have relatively low strength and wear resistance, they have good corrosion resistance and low-cost advantages.
• Steel pipe: Steel pipe is a very sturdy and durable pipeline material, suitable for high-pressure and high-temperature environments, but its weight is heavy and installation and maintenance costs are high
