Embodiment Construction

[0010] See figure 1 , the present invention has a hollow pipe body 1 made of stainless steel, the pipe body 1 is a seamless pipe; the outer wall surface of the pipe body 1 is coated with a zirconium nitride layer 2, and the inner wall of the pipe body 1 is attached with a plastic Lining layer 3. Since the hardness of the zirconium nitride layer 2 is relatively high, it can effectively prevent hard objects from abrading the tube body. And because the inner lining layer 3 is made of plastic material, it has good anti-corrosion performance, so it can obviously improve the service life of the product, and when the medium in the pipe is suitable for the occasion of plastic, its performance is even more superior. The thickness of the above-mentioned zirconium nitride layer 2 is 0.3-0.5mm, and the thickness of the lining layer 3 is less than 2mm, which will not affect the use of the product.

[0011] The specific embodiments described above have further described the purpose, techn...

Abstract

The invention relates to a stainless steel tube. The stainless steel tube comprises a hollow tube body with stainless steel materials; an outer wall surface of the tube body is plated with a layer of zirconium nitride; an inside liner with plastic materials is attached on an inner wall of the tube body; the thickness of the zirconium nitride layer ranges from 0.3m to 0.5m, and the thickness of the inside liner is less 2mm. The stainless steel tube is simple in structure, good in anti-wear performance and anti-corrosion performance.

Description

technical field [0001] The invention relates to a steel pipe, in particular to a stainless steel pipe. Background technique [0002] Stainless steel refers to steel resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. The basic alloying elements of stainless steel include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for the structure and performance of stainless steel. Stainless steel is easily corroded by chloride ions, because chromium, nickel, and chlorine are isotopic elements, and the isotopic elements will be exchanged and assimilated to form corrosion of stainless steel. Moreover, the strength of stainless steel is also very high, so it is widely used in some building components and pipelin...
