Thin wallstainless steel pipe, If the pipe fittings are treated with impurity removal, pickling, and passivation, the thickness of the generated Cr2O3 can be increased, and the uniformity of the fineness can be enhanced; the polishing of the stainless steel pipe and the finishing process of the pipe can not only eliminate the appearance defects, but also make it dull. The chemical film is more delicate and dense to reduce the probability of pitting corrosion. At the same time, the inner wall of the pipe fittings is bright and the friction is small after finishing, which further improves the hydraulic performance of the pipe and saves consumption.

Introduction to the installation points of thin-walled stainless steel pipes:

1. The pipeline shall not be cast in the reinforced concrete structure layer.

2. Plastic-coated stainless steel pipes should be used for buried ground to avoid acid-base corrosion of the outer wall of the pipe and damage to the surface of the pipe by hard debris.

3. Stainless steel pipes should not pass through settlement joints, expansion joints and deformation joints of buildings. When it is unavoidable, technical measures to avoid damage to the pipeline should be adopted.

4. Stainless steel pipes and pipe fittings should not be in direct contact with cement, cement mortar and concrete. In order to avoid chloride corrosion to the pipeline, it can be protected by plastic film or wrapped with anti-corrosion tape.

Thin-walled stainless steel pipes can save materials: because the thin-walled type is selected, the weight is only 1/3 of the galvanized pipe, which saves a lot of materials and reduces the weight of the product, especially suitable for high-rise buildings. Products can be recycled and reused, in line with my country's industrial policy.

Thin-walled stainless steel pipe has strong corrosion resistance: stainless steel pipe has very good corrosion resistance, stainless steel can withstand 200ppm chloride, stainless steel can resist water corrosion of chloride, and the surface of the pipe is in contact with oxygen to actively generate fine and strong corrosion resistance. The chromium oxide protective film is designed to select stainless steel, and there is no need to consider the corrosion margin.

The domestic thin-walled stainless steel pipe is a new type of pipe that came out in the late 1990s. Because of its hygienic, high strength, good corrosion resistance, sturdiness and durability, long life, protection-free, and beautiful features, the development of stainless steel water pipes is now strong. It has been widely used in the construction of water supply and direct drinking water pipelines.

The use of thin-walled stainless steel pipes has expanded from the current water supply and direct water supply pipelines to heating, gas pipelines, food, medicine, chemical, electronics, and fire protection industries.
