Why do stainless steel precision steel pipes need metallographic inspection
From the perspective of metallography, because stainless steel precision steel pipes contain a high content of chromium, chromium forms a very thin chromium film on the surface. This film isolates the oxygen that invades the steel, thus playing a role in corrosion resistance. For stainless steel ...Read more -
Small-diameter precision stainless steel pipe processing-polishing
Small-diameter precision stainless steel pipes are widely used due to their high corrosion resistance and economic practicality, especially in medical equipment, mechanical parts, experimental equipment, etc. Precision stainless steel pipes should be corrosion-resistant, bright in appearance, and...Read more -
The simple method to identify stainless steel pipes
First, magnetic test The magnetic test is the simplest way to distinguish annealed austenitic stainless steel pipes from ferrite stainless steel pipes. Austenitic stainless steel pipes are non-magnetic steels, but they will have a slight magnetism after being cold worked under heavy pressure; pur...Read more -
Corrosion-resistant conventional galvanized steel pipe and its application fields
Conventional galvanized steel pipe is a steel pipe that has been hot-dip galvanized and has good corrosion resistance. It is widely used in construction, machinery manufacturing, road traffic, and other fields. Galvanized steel pipes are immersed in molten zinc liquid to form a zinc layer coverin...Read more -

Introduction to nondestructive testing of pressure vessels such as boiler steel pipes
Pressure vessels such as boiler steel pipes and pressure vessel components often have defects that are difficult to detect, such as lack of fusion, lack of penetration, slag inclusions, pores, cracks, etc. in the welds. It is impossible to conduct destructive inspections on each boiler or pressur...Read more
