Lined stainless steel clad pipe

First, it has good mechanical properties. Because both inner and outer layers are metal materials, they have strong compressive, impact resistance, high tensile strength, high elongation, high modulus of elasticity and low coefficient of thermal expansion. Especially suitable for building water supply riser hidden application.

2. High bonding strength. Carbon steel stainless steel composite pipe is a kind of steel pipe with inner layer embedded in hot-dip galvanized steel pipe. Under the action of mechanical force, the elastic deformation of outer carbon steel pipe and plastic deformation of inner stainless steel pipe make the two layers of material closely intertwined. Its bonding strength exceeds 1 MPa stipulated by the national standard. Because the inner and outer materials are similar, there will be no split phenomenon.

3. Good rust and corrosion resistance. The stainless steel material is superior to other materials in rust and corrosion prevention because of its chemical properties such as rust and oxidation resistance, acid and alkali resistance, and good intergranular corrosion resistance. Lining stainless steel composite pipe and lining stainless steel pipe fittings and stainless steel pipe fittings matching connection, its application scope is wider, in addition to a water supply and heating, but also applicable to chemical, pharmaceutical, petroleum, food, power and other industries with high anti-corrosion requirements.

Fourth, heat-resistant and cold-resistant, cold and hot dual-purpose. The liquid nitrogen freezer is made of stainless steel, so the stainless steel composite pipe has excellent heat and cold resistance, and it is suitable for both cold and hot water pipes.

5. Large diameter and small resistance. The inner stainless steel of the lined stainless steel composite pipe is only 3b8mm, so the actual diameter is basically consistent with the prescribed diameter. Moreover, the inner wall is smooth, non-scaling, low resistance and large flow.

6. High working pressure. The lined stainless steel composite pipe can ensure that the working pressure is more than 2.5 mpa, and can meet the needs of various construction water supply projects.

7. Easy installation and simple process. Carbon steel lined stainless steel composite pipes are installed with galvanized steel pipes. Wire joints are used below DN100 and groove joints are used above dn100. The process is simple and installation workers do not need special training.

8. Good hygiene, environmental protection and safety. Because stainless steel material is chemically stable and harmless to human body, stainless steel material is used in various kinds of stents, splints and internal fixation screw implanted in human body by international and domestic medical circles. The secondary pollution caused by water quality can be effectively prevented by the matching connection of the lined stainless steel composite pipe with the composite pipe fittings and the non-toxic rust-proof treatment of the joint threads and end faces. The inner stainless steel composite pipe system is made of stainless steel, which is hygienic, environmentally friendly and safe. It meets the requirements of "ecological residence" and the people-oriented concept of the times.
