Rustproof DN2000 Bi Metal Pipe , Stainless Steel Plumbing Pipe

Product Specification

Rust-proof and corrosion-resistant lining stainless steel composite pipe

1. Has good mechanical properties:
Because the inner and outer layers are made of metal materials, it has strong compressive and impact resistance, high tensile strength, high elongation, high elastic modulus, and low thermal expansion coefficient. It is especially suitable for risers and branch pipes of high-rise building water supply. .
2. High bonding strength:
The lining stainless steel composite pipe is to sleeve the inner stainless steel pipe into the carbon steel pipe. Under the action of mechanical squeezing force, the outer carbon steel pipe is elastically deformed, and the inner stainless steel pipe reaches plastic deformation, so that the two layers of materials are tightly fitted. Its bonding strength exceeds the requirements of the national industry standard and reaches more than 1MPa. Because the inner and outer layers are similar in materials and have strong bonding force, there will be no peeling of the two materials during groove pressing and cutting, preventing the occurrence of galvanic corrosion.
3. Good rust and corrosion resistance:
The stainless steel material has chemical properties such as anti-rust and oxidation resistance, acid and alkali resistance, and good intergranular corrosion resistance, and its anti-rust and anti-corrosion performance is superior to other materials. The lining stainless steel composite pipe and the lining stainless steel composite pipe fittings are connected with a wider range of applications. They are mainly used for water supply, heating, air conditioning, fire protection, chemical industry, medicine, petroleum, food, electric power, metallurgy and other high anti-corrosion requirements. industry.

4. Heat-resistant and cold-resistant, dual-purpose cold and hot:
The working temperature of temperature-resistant stainless steel can reach -40℃-350℃. The cold resistance performance is also very good. For example, the liquid chlorine freezer uses stainless steel, so the stainless steel composite pipe lined with excellent heat resistance and cold resistance, and regardless of the hot and cold water pipes, one pipe is used for two purposes, both cold and hot.
5. Large diameter and low resistance:
The inner layer of stainless steel composite pipe lined with stainless steel is only 0.25~0.7mm, so the actual diameter is basically in line with the specified diameter, and the inner wall is smooth, sanitary, non-scaling, small in resistance, and large in water flow.
6. High working pressure:
The lined stainless steel composite pipe has good rigidity, pressure resistance, no leakage, and can ensure the working pressure ≥2.5MPa, ≤3.5 MPa, which can meet the needs of various construction projects.
7. Convenient installation and simple process:
The installation of lining stainless steel composite pipe is equivalent to ordinary galvanized steel pipe, wire connection is used for DN100 and above, groove connection is used for DN100, the process is simple, installation workers do not need special training, the probability of joint leakage is almost zero, safe and reliable, and easy to maintain.
8. Sanitation and environmental protection, good safety:
As the stainless steel material has stable chemical properties and no harm to the human body, the various brackets, splints, and internal fixation screws implanted in the human body in the international and domestic medical circles are all made of stainless steel. The lined stainless steel composite pipe is connected with the composite pipe fittings, and the threads and end faces of the joints are coated with anticorrosive liquid, which can effectively prevent secondary pollution to the water quality. The fluid transmission part of the lining stainless steel composite pipe system is all made of stainless steel, which is hygienic, environmentally friendly, safe, and has a long service life, in line with the development requirements of "ecological residence" and the people-oriented concept of the times.
Application areas of lining stainless steel pipes:
(1) Water supply introduction pipe
(2) Outdoor water supply pipes
(3) Pipes for pump room
(4) High-rise building water supply pipes and water distribution main pipes
(5) Air conditioning circulation pipes and fire sprinkler pipes
(6) Hot water pipes, direct drinking water pipes
(7) Water supply pipes for finely decorated high-end commercial houses, etc.
