Problems solved by technology

Stainless steel seamless steel pipe has been widely used in many fields at present. The seamless steel pipe is made of food-grade stainless steel, which has very outstanding anti-rust and anti-fouling characteristics. Therefore, the quality of stainless steel represents the quality of stainless steel seamless steel pipe. Quality, so the production process of stainless steel is particularly important. The stainless steel process method of the prior art cannot meet the needs of the application. The stainless steel produced has a short life, and frequent replacement of steel pipes will increase the production cost. Therefore, it is necessary to use stainless steel for seamless steel pipes. Further Improvement of Fabrication Process of Uncovered Steel Pipe

Abstract

The invention discloses a production method for a stainless steel seamless steel tube. The production method comprises the following steps: immersing the stainless steel seamless steel tube into an acidic solution to perform chemical reaction; flushing inner and outer surfaces of the stainless steel seamless tube through pressure water, and performing point-like polishing on surface defects of theacidified stainless steel seamless steel tube; fixing the stainless steel seamless tube onto an oil coater so as to be fixed, and using a rotary brush to coat oil for inner and outer surfaces, and lubricate. The production method has the beneficial effects that: production efficiency is improved, and stable product quality also can be guaranteed according to the production method for the stainless steel seamless steel tube and application of the production method; special cleaning fluid can be used for enabling the steel tube to obtain uniform surface quality, so that the service life of thesteel tube is prolonged; and moreover, several different cold-processing methods are disclosed according to different needs, so that different consumer needs can be met, sales range is increased, andeconomic benefits are improved.

Description

technical field [0001] The invention relates to a production method of seamless steel pipes, in particular to a production method of stainless steel seamless steel pipes. Background technique [0002] Stainless steel seamless steel pipe is a seamless steel pipe made of stainless steel. It has very good anti-oxidation properties, is safe and hygienic, and is widely used in food, medicine, heating, domestic water, air-conditioning return water and other fields. According to the hardware and steel building promotion center The data shows that stainless steel seamless steel pipes have a better heat transfer effect than carbon steel seamless steel pipes, and have a longer service life. Stainless steel seamless steel pipe has been widely used in many fields at present. The seamless steel pipe is made of food-grade stainless steel, which has very outstanding anti-rust and anti-fouling characteristics. Therefore, the quality of stainless steel represents the quality of stainless ste...
