How long is the service life of the composite polyethylene pipe with steel belt from Kongwang?

Under normal operating conditions in compliance with usage specifications, the service life of perforated steel belt polyethylene composite pipes typically reaches 50 years. This lifespan expectation is primarily attributed to the stable performance provided by its special structure and high-quality materials, with the following specific supporting factors:

Excellent Corrosion ResistanceThe inner and outer layers of the pipe are made of polyethylene material, with the cold-rolled steel strip frame completely encapsulated within the plastic layers. This design prevents the steel strip from being eroded by acidic and alkaline substances, microorganisms in the soil, and eliminates issues of electrochemical and oxidation corrosion, fundamentally reducing the lifespan of the pipe due to corrosion and aging.

2. Strong structural stability:The steel strip, after being punched and welded into a framework, provides the pipe with a low coefficient of expansion and creep resistance similar to that of steel pipes. Simultaneously, the polyethylene layer and the steel strip form a strong mechanical interlock through the holes, preventing delamination of the composite layer. This structure can withstand the stresses caused by underground soil pressure, heavy surface loads, and temperature changes, reducing the risk of pipe deformation and cracking, and ensuring the structural integrity for long-term use.

3. Reliable Connection with Leak-Proof DesignThe pipe fitting used in this pipe material is connected by electric heat-fused joints. After welding, the plastic of the pipe and fitting can melt and integrate into one, resulting in a high strength connection and excellent sealing. This prevents local damage caused by leakage, loosening, and other issues at the pipe joint, thereby ensuring the long-term stable operation of the entire pipeline system and extending its overall service life.

However, if the environment exceeds the standard range, such as for long-term conveyance of mediums with temperatures exceeding 60°C, highly corrosive industrial wastewater, or if the pipeline is damaged during installation or the joints are not properly welded, the actual service life will be less than 50 years.
