Scrap Handling In The Production Of Stainless Steel Welded Pipes

Scrap handling in the production of stainless steel welded pipes

Stainless steel welded pipe, referred to as welded steel pipe, is a steel pipe made of commonly used steel or steel strips after being crimped and formed by a unit and a mold. Welded steel pipes have simple production process, high production efficiency, many varieties and specifications, and less equipment investment, but the general strength is lower than that of seamless steel pipes.(Seamless pipe means a long steel strip with a hollow section and no joints around it.)

Many users of stainless steel welded pipes are very curious about how to deal with the waste in the production process of stainless steel welded pipes. In fact, stainless steel welded pipes are prone to produce a lot of waste in the production process, which are mainly divided into stainless steel dust waste and solid waste.

Stainless steel dust waste is mainly generated during the storage inspection and preliminary processing of stainless steel welded pipe blanks.After the stainless steel welded pipe blank is perforated, the surface is a relatively thick oxide layer. Before being put into production in the production workshop, the black oxide layer on the surface must be removed.The first purpose is to detect whether there are cracks with the naked eye, and the second is to peel off the impurities on the surface, the surface of the stainless steel welded pipe will be better when it enters the production workshop. Dust waste is generally recycled by manufacturers using professional stainless steel dust collection equipment.

In the production process of stainless steel welded pipes, some scraps will also be produced, which are mainly recycled to stainless steel scrap recycling companies for processing to increase the utilization rate. In order to further realize green and environmentally friendly production management, more and more enterprises pay more attention to waste disposal, which not only creates a good development environment for enterprises, but also saves costs for enterprises and turns waste into treasure.

The quality of stainless steel welded pipes is affected by many factors, including environmental factors at the production site. The production of stainless steel welded pipes requires an independent production workshop or a special fixed production site.Stainless steel raw materials must be stored separately and cannot be mixed with carbon steel.Stainless steel welded pipe raw materials and semi-finished products should be equipped with necessary anti-iron pollution and scratches during transportation during turnover and transportation.

When the welded pipe is welded, the stainless steel welded pipe is not allowed to pass through the wind, avoid wind, rainfall, and direct impact on snow, and the temperature is not lower than -5°C. Stainless steel welded pipes must have special welding materials to ensure that the storage temperature is not lower than 18° and the humidity is not more than 60%. The production environment of stainless steel welded pipe generally requires comprehensive quality control of stainless steel welded pipe, and responsible manufacturers must strictly require the implementation of environmental control of stainless steel welded pipe production.
