In daily life, there are many factors that cause the damage and corrosion of the outer surface of stainless steel pipes. This reminds us that we should strengthen the maintenance of stainless steel pipes in various processes. Let's introduce the methods to improve welding quality. In daily life, there are many factors that cause the damage and corrosion of the outer surface of stainless steel pipes. This reminds us that we should strengthen the maintenance of stainless steel pipes in various processes. Let's introduce the methods to improve welding quality.
1. The processing and consumption of stainless steel pipes should have a dedicated workshop (wooden boards are good) to avoid indirect contact between austenitic stainless steel and carbon steel processing platforms or solid aerial indirect contact.
2. There should be special storage racks. The storage racks for stainless steel tubes should be wooden or painted carbon steel brackets or rubber pads to isolate them from carbon steel and other metal materials. When storing, the storage position should be convenient for hoisting, isolated from other storage areas, and protective measures should be taken to avoid liquid purification, avoid collisions with other components, and prevent iron and metal purification and damage.
3. When hoisting stainless steel pipes, public slings should be used, such as hoisting belts and public chucks. It is strictly forbidden to use wire ropes to avoid scratching the surface; and when hoisting and placing, prevent impacts and bumps from causing scratches. If there are surface scratches, arc marks and surface purification during transportation, storage and processing, they should be thoroughly cleaned up, and then polished with an angle grinder, and then polished with a polishing sheet or metallographic sandpaper.
The above are several measures to improve the welding process of stainless steel pipes. Special attention should be paid to the surface of the stainless steel pipe during the processing process, and there should be no cracks, folds, cracks, etc. Ensure the normal use of steel pipes.
