Seven properties and application range of steel belt reinforced pipe Steel pipe is also called burial steel reinforced polyethylene (HDPE) spiral corrugated pipe (hereinafter referred to as MRP), which is a new type of plastic buried drainage developed in China in recent years. tube. The product is compressed with a continuous steel strip into a similar shape of spiral steel ribs wrapped between two inner and outer layers of heat-sealed polyethylene, combining the high steel strength, high strength of the steel and the flexibility, corrosion resistance and wear resistance of the polyethylene. . Production diameter range of 300-2200 mm, length 6-10 meters, ring steel can reach SN8, SN12.5, SN16, SN18 four grades. Make up for the past large diameter plastic buried drain pipe general ring stiffness can only reach SN8 limits. The product can be adapted to different engineering needs by a variety of connection methods, and better meets the requirements of sealing reliability and convenient connection construction.
Steel belt reinforced pipe performance:
First, the extremely low friction coefficient, small fluid resistance: high wall finish and low friction coefficient.
Second, it is not easy to scale: the surface adsorption force is very weak, and the anti-adhesion ability is strong, so the surface of the pipe is not easy to adhere to other materials and is not easy to scale.
Third, the connection is convenient: it can be flanged directly on the parent body, no need to weld the pipe fittings, avoiding the phenomenon of broken pipe fitting due to poor welding, which can save the cost of pipe fittings.
4. Corrosion resistance: The chemical stability is very high. Except that some strong oxidizing acids can be slightly corroded under high temperature, other acid and alkali liquids are not easy to corrode and resist aging.
V. Stable flame retardant and antistatic properties: good flame retardant and antistatic properties, all meeting the standard requirements.
6. Long service life: The service life of the well is more than 20 years, and the economic benefits are remarkable.
Seven, the steel belt reinforced tube also has non-fouling and corrosion resistance: the self-lubricating and non-adhesive properties of the steel belt reinforced tube, and the friction coefficient is the smallest. The inner wall of the pipe produced by the special process is corrosion-resistant, anti-wear and non-fouling, so the flow resistance is small, and the flow rate and flow rate can be maintained for a long time. Its inner diameter design can be reduced by 15.4% compared to steel pipes. This feature is of great significance for the use of thermal power stations for the discharge of fly ash systems. It is also very suitable for pipelines such as crude oil and mud. It has excellent chemical resistance, in addition to strong oxidizing acid, it can withstand various corrosive media (acid, alkali, salt) and organic media (except naphthalene solvent) at a certain temperature and concentration range, at 20 ° C and It was immersed in 80 kinds of organic solvents at 80 ° C for 30 days, and there was no abnormality in appearance, and other physical properties were hardly changed.
HDPE steel belt reinforced pipe is also called steel belt reinforced polyethylene spiral corrugated pipe for buried drainage. It can be adapted to different engineering needs by various connection methods, and better meets the requirements of sealing reliability and convenient connection construction.
HDPE steel belt reinforced pipe can be applied to sewage treatment plant filtrate collection pipeline, industrial sewage discharge pipeline, garbage treatment plant filtrate collection pipeline, highway drainage pipeline, municipal drainage sewage pipeline network, cable, cable sheathing pipeline, water collection system, Water seepage system pipelines, sea water, rainwater pipelines, water pipelines for agricultural irrigation.
