Engineering Embedded Steel Mesh Skeleton PE Composite Pipe Strength Supply

#Core performance requirements for pipelines in engineering pre-embedding scenarios

The pre-embedded pipeline of the project is a concealed project. Once the failure occurs, the maintenance cost is extremely high, so there are strict requirements for the pressure resistance, corrosion resistance and settlement resistance of the pipeline. Ordinary pure PE pipes have limited pressure-bearing capacity and cannot meet the needs of high-rise water supply, fire protection pipe network and other high-pressure scenarios; steel pipes have poor corrosion resistance and are easy to rust and leak when pre-embedded in wet or acid-alkali soil. Steel mesh skeleton PE composite pipes use steel mesh as a reinforced skeleton, combining the corrosion resistance of PE material and the high pressure-bearing of steel. The pressure-bearing capacity of conventional products can reach 1.6MPa, and the normal service life can reach 50 years. They are fully suitable for various pre-embedded scenarios such as municipal water supply and drainage, residential pipe network, and industrial fluid transportation.

#Selection points of steel mesh skeleton PE composite pipe for pre-embedding

When selecting the type, first match the pressure level of the pre-embedded scene. The pre-embedded in the passageway and heavy-load areas should choose a higher pressure level than the conventional scene to avoid pipeline cracking caused by settlement and extrusion. Secondly, check the uniformity of the wall thickness of the pipe to confirm that the inner steel wire mesh has no offset or ruth problem, and whether the matching electrofusion pipe fittings fully match the pipe diameter and pressure level to avoid later interface leakage. Also pay attention to check whether the product meets the requirements of the national standard, whether the relevant test reports are complete, and do not choose non-standard products in order to reduce the budget.

#Core screening criteria for strength sources

To identify reliable sources of goods, don't just compare quotations. First, look at the stocking capacity, whether the conventional caliber (dn50-dn630) is in sufficient stock, and whether special length pipes can be customized on demand to reduce the number of on-site joints and reduce the risk of leakage. Secondly, look at the supply timeliness, whether it can match the project nodes to deliver in batches on demand to avoid missed work. It also depends on whether the source can provide supporting construction technical support, such as parameter guidance for fused connections and specification suggestions for pressing tests to help the construction party reduce the operating error rate.

For the engineering side, selecting the right supply of steel mesh skeleton PE composite pipes can not only control the procurement cost, but also reduce the later failure probability of hidden projects from the source and improve the overall project quality.
