How to deal with oxidized white spots on stainless steel pipe fittings

White spots are formed on the surface, and corresponding treatment must be made at this time, but how should we deal with it?
　　 1. Surface polishing method.
　　 Polishing can fill the pores of stainless steel pipes with the ground aluminum powder.
　　2. High voltage and high current density impact method.
　　In the early stage of anodizing, high-voltage and high-current impacts are used, so that large and small stainless steel pipes that were previously cut by impurities are connected into pieces by high current impact.
　　 3. Exterior shot peening method.
　　 Because the power of shot peening will be greatly improved, the effect of such stainless steel pipe fittings after anodizing and dyeing will be surprisingly good.

The difference between seamed stainless steel pipe and seamless stainless steel pipe

The main purpose of seamless steel pipe

Although stainless steel plates account for a relatively small proportion of world steel consumption, they are still vital to specific manufacturing industries such as the energy and food processing markets. At present, the global consumption of stainless steel plate materials is continuously increasing.

Production process of welded steel pipe

The development of steel pipe production technology began with the rise of bicycle manufacturing, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry, and The drilling and transportation of oil and natural gas have strongly promoted the development of the steel pipe industry in terms of variety, output and quality.

Steel prices have risen by more than a thousand steel companies generally turn losses into profits

Since the first half of last year, steel prices have begun to recover thanks to a series of measures such as supply-side reforms and elimination of backward production capacity. Taking rebar as an example, the average price on March 9 last year was 2475 yuan/ton, and on March 9 this year, it has risen to 3852 yuan/ton, an increase of 35%.

China Steel Association: Steel prices in the domestic market continued to rise slightly in September

According to data from the China Iron and Steel Association, in September, the domestic steel market demand was strong, and steel prices continued to rise. Affected by the rapid release of steel production capacity, pressure on the supply side has risen, and the price increase of steel has narrowed.
