1.6MPa high-pressure steel mesh skeleton composite pipe, corrosion-resistant and durable

■ 1.6MPa high pressure steel mesh skeleton composite pipe core performance advantages

This pipeline is made of high-strength steel wire woven mesh as the intermediate reinforcement layer, and the inner and outer layers are attached to polyethylene material. The pressure-bearing capacity can reach 1.6MPa, which is suitable for most high-pressure fluid transportation scenarios. Compared with ordinary steel pipes, it does not have the problem of oxidation and rust, and has strong resistance to acid, alkali salts, and weak corrosive chemical media. Long-term buried use will not cause corrosion and thinning of the pipe wall and leakage. The normal service life can reach more than 50 years. The operation and maintenance cost is much lower than that of traditional metal pipes, and it is also more than 3 times higher than the pressure-bearing capacity of ordinary PE pipes.

■ Scope of application of multi-scenario engineering

Its corrosion resistance and high-pressure bearing characteristics can cover multiple application scenarios such as municipal high-pressure water supply and drainage, urban secondary water supply, chemical corrosive fluid transportation, mine slurry transmission, and oil field water injection. It is especially suitable for buried laying scenarios with strong soil corrosiveness, as well as long-distance transportation projects with high pressure requirements on pipelines. It can effectively reduce the probability of later leakage maintenance and reduce the investment in engineering operation and maintenance.

■ Selection points to pay attention to

When selecting the type, it is necessary to match the temperature, corrosion grade, and long-term working pressure of the actual conveying medium. Pipes of 1.6 MPa size are suitable for scenarios where the long-term working pressure does not exceed 1.6 MPa. At the same time, matching pipe fittings of the same pressure level should be selected to avoid problems such as interface leakage and insufficient pressure bearing caused by the mixed use of different pressure grade fittings. In low temperature environments, additional attention should be paid to the low temperature impact resistance parameters of pipes.

■ Precautions for construction and installation

Before construction, it is necessary to check whether the outer wall of the pipe is damaged by bumping one by one to eliminate hidden cracks caused during transportation; during hot-melt connection, the heating temperature and docking time should be strictly controlled to ensure uniform welding of the interface and avoid virtual welding; when laying in the ground, it is necessary to do a good job of sand and gravel cushion, remove the sharp stones in the groove, and layer and compact when backfilling to avoid local stress causing pipe deformation and affecting long-term performance.

Overall, the 1.6 MPa high-pressure steel mesh skeleton composite pipe takes into account the advantages of high-pressure bearing, corrosion resistance and aging resistance, and has a lower cost of use throughout the life cycle. It is a highly adaptable choice for pipeline transportation under various high-pressure and corrosive conditions.
