Physical properties is to ensure that the stainless steel material performance parameters of the main indicators, it depends on the composition of the steel heat treatment and management system.

Sharing: precision steel pipe fire protection measures
1, outsourcing layer. Outsourcing is in auto precision steel tube appearance add layer, can cast-in-situ forming, spraying method can also be adopted.

Precision steel tube must raise service life. First, for precision steel tube in pickling passivation to get rid of the oxide skin appearance, then carry out RunHua solved, thus for pipes to carry out the acid treatment and passivation to generate a layer. Protective film.

Galvanized pipe processing after plating process including pretreatment, plating and electroplating processing. The electroplating process depends on the quality of coating materials and plating process is influenced by side impact beams many factors.

Precision steel pipe pickling passivation technology elements: the purpose is to provide a pickling passivation process, the technology can reduce the material cost, at the same time, the process can increase the manufacture of precision steel pipe pickling passivation speed, reduce the ma
