Introduction to PSP steel - plastic composite pressure pipe
Gangsu composite pressure vessel (Plastic - steel - Plastic composite pressure pipe) referred to as "(PSP), five layer composite structure is a type of steel, Plastic composite pipe, overcome the steel tube is easy to rust, pollution, heavy, and the strength of the Plastic pipe is low, short service life of large amount of expansion and the defects of easy deformation, and and has advantages of steel pipe and Plastic pipe joint.With smooth inner wall, chemical corrosion resistance, no pollution, fluid resistance, no scaling, no breeding of microorganisms, fluid from secondary pollution and other advantages, at the same time with high pressure, long life, less maintenance characteristics.It is an excellent product with reasonable structure, excellent performance, long service life, superior comprehensive performance and high cost performance.Among all steel and plastic composite pipes, the steel and plastic composite pressure pipe and "PSP" are unique, referring to the pipes defined in CJ/ t183-2008 standard.
Performance characteristics of PSP steel - plastic composite pressure pipe
1, excellent mechanical strength: high strength, rigidity, impact resistance, stable pressure performance;Mechanical properties, tensile strength 275 ~ 320MPa, is 7 ~ 8 times of pure plastic pipe.
2. Thermal conductivity: 0.46 ~ 0.57W/m.k, about 1/100 of the steel pipe and close to the thermal conductivity of plastic pipe.
3. Hydraulic performance: the inner wall roughness of steel-plastic composite pressure pipe is 0.007mm, and the inner wall is smooth. When transporting fluid, the resistance loss is small, and no scale is formed.The pipe wall is smooth and clean, the flow resistance is small, no scaling, and the water head loss is 30% less than that of metal pipe under the same pipe diameter and pressure conditions.
4, corrosion resistance: without any corrosion treatment can be installed, save engineering costs, steel and plastic composite pressure tube outer layer of plastic, including PE, PERT, pe-x \PPR, etc., are a non-polar material, very stable chemical properties, normal temperature insoluble in most of the known solvent, can withstand a variety of acid, alkali, salt solution corrosion.
5, sanitary performance: steel-plastic composite pressure pipe is sanitary and non-toxic, the contact medium is plastic, no matter PE/PERT/ pe-x \PPR, all in line with GB/T 17219 standard, can be used for direct drinking water transportation.
PSP steel - plastic composite pressure pipe applications
1. Urban piped water supply system
2. Natural gas transmission system
3. Communication system (cable sheath)
Drinking water supply system for high-rise buildings
5. Municipal engineering and industrial fields
