精密无缝管表面处理工艺： 1、精密无缝管除油脱脂 精密无缝管的表面在进

Precision seamless surface treatment: <br>1, precision seamless degreasing <br>before performing precision seamless surface passivation and pickling process, must first degreasing process, a degreasing treatment must also be performed further row after welding assembly, to avoid carbon pick-up at high temperatures. <br>2, precision seamless tube passivation <br>passivation process can handle sophisticated surface precision steel and stainless iron, fine light pipe primary purpose is to avoid the passivation of precision seamless surface oxidation and corrosion. <br>3, pickling precision seamless <br>precision seamless pickled is intended to remove the high temperature solder, or heat treatment after hot working scale precision seamless appearance. Also the purpose of eliminating steel or iron or steel particulate contaminants red rust corrosion. But after pickling should pay attention to timely clean acid pickling precision seamless surface, otherwise the surface of the steel pipe will soon begin to rust corrosion. Lead to a decline in the steel surface layer below the corrosion resistance.

Precision seamless tube surface treatment process:<br> 1, precision seamless tube degrease<br> The surface of the precision seamless tube must be treated with degrease before passivation and acid washing, and further components must be welded in a degresive treatment to avoid the carbon of the picker at high temperatures.<br> 2, precision seamless tube passivation<br> The passivation process can only deal with precision steel pipes and rust-free iron, the primary purpose of the dull light pipe passivation is to avoid precision seamless tube surface oxidation and corrosion.<br> 3, precision seamless tube acid washing<br> Precision seamless tube acid washing treatment is intended to remove high temperature welding, heat treatment or heat processing after precision seamless tube exterior oxidation skin. It can also eliminate red rust corrosion of steel or iron or steel particle pollutants. However, the acid washing needs to pay attention to the acid to clean the surface of the precision seamless tube in time, otherwise the steel pipe surface will soon begin to rust and corrode. Causes a decrease in corrosion resistance on the surface of the steel pipe below.

Surface treatment process of precision seamless pipe:<br>1. Degreasing of precision seamless pipe<br>Before passivation and pickling treatment, the surface of precision seamless pipe must be degreased and degreased, and further components must be welded in degreasing treatment line to avoid carbon in high temperature.<br>2. Passivation of precision seamless pipe<br>Passivation process can only deal with precision steel pipe and stainless iron. The primary purpose of passivation is to avoid surface oxidation and corrosion of precision seamless pipe.<br>3. Pickling of precision seamless pipe<br>The purpose of pickling treatment of precision seamless pipe is to remove the oxide skin on the surface of precision seamless pipe after high temperature welding, heat treatment or heat processing. It can also eliminate the pollution of steel or iron or steel particles corroded by red rust. But pay attention to clean the acid on the surface of precision seamless pipe in time after pickling, otherwise the surface of steel pipe will start to rust soon. This results in a decrease in the corrosion resistance of the steel pipe surface below.<br>
