The steel mesh skeleton polyethylene composite pipe, also known as PSP pipe and SRTP pipe, is a new type of environmental protection pipe that takes high-strength steel wire wrapped in the pipe as the reinforced skeleton, its inner and outer layers take high-density polyethylene as the matrix, and is compounded by hot melt adhesive through continuous extrusion. It is widely used in municipal water supply, fire protection, oil and gas fields, chemical industry, smelting, and seawater transportation.
So, what are the differences between the steel mesh skeleton pipe with similar appearance to the PE water supply pipe? Now let's introduce how to distinguish PE water supply pipe from steel mesh skeleton pipe? PE water supply pipe: general purpose pressure water transmission and urban water supply pipe drinking water transmission steel mesh skeleton pipe: urban water supply, urban gas, fire water supply, mine pipe, special fluid transmission steel mesh skeleton pipe: five layer structure, the inner and outer layers are PE plastic layers, and the middle layer is steel mesh skeleton layer.
The inner and outer layers and the middle layer are bonded with PE water supply pipes through the hot-melt adhesive layer: they are polymerized from monomer ethylene. Because of different polymerization conditions such as pressure and temperature during polymerization, composite pipes of resins with different densities can be obtained. Steel wire mesh skeleton pipe: it is a composite pipe made of high-strength superplasticized steel wire mesh skeleton and thermoplastic polyethylene as raw materials, and steel wire winding mesh as the skeleton reinforcement of polyethylene plastic pipe.
PE water supply pipe: hydrostatic strength, elongation at break, longitudinal shrinkage, oxidation induction time, weather resistance, sanitary performance, melt mass flow rate. When processing PE pipes, no heavy metal salt stabilizer is added, the material is non-toxic, no scaling layer, and no bacteria, which solves the secondary pollution of urban drinking water. Wire mesh skeleton pipe: hydrostatic strength and bursting pressure of pipe fittings, hydrostatic stability of composite layer, thermal stability, melt mass flow rate, hygiene, weather resistance, peel strength and pressure cracking stability.
