1. Smooth surface, vertical and high accuracy; 2. It has high compressive strength and strength, and has a long service life; 3. Strict dimensional tolerances reduce machining time; 4. The surface is

1. Eddy current testing can be used instead of pressing test. The experimental working pressure or eddy current testing should meet the relevant requirements as compared with the sample specifications

The gas cylinder tube is an accessory that connects to the outside world. In the case of pumping gas cylinders, metal hoses must be used due to the high working pressure. The gas in the bottle should

Gas cylinder pipe is a kind of seamless steel pipe, collectively referred to as seamless steel pipe for gas tank. Manufacture of gas tanks such as composite coiled gas tanks. What is the manufacturing

The honing tube is a high-precision steel tube material, which integrates the advantages of no oxide layer on the outer wall, no leakage under high pressure, high precision, high finish, no deformatio

The first stage is the shedding and cutting stage. In this constant pressure honing, at the beginning, due to the roughness of the hole wall, the contact area between the oilstone and the hole wall is

The cold drawn pipe has the characteristics of no air oxide layer on the inner and outer walls, no leakage under high pressure, high smoothness, no deformation after cold drawing, no gap in the flarin

The wall thickness of the cold-drawn pipe should be uniform, and there should be few defects on the inner and outer surfaces; it is necessary to equip the outer surface polishing and inner hole defect

Gas cylinder tube is a general term for the production of seamless tubes for gas cylinders and high-pressure vessels. There are many types of gas cylinders. In addition to general oxygen cylinders and

Gas cylinder pipe is a kind of seamless steel pipe, commonly known as seamless steel pipe for gas cylinder. Waiting for the production of gas cylinders. What are the production processes of seamless s

In the actual production of cold-drawn steel pipes, it is often affected by various factors. That is to say, the defects caused by cold drawn steel pipes are often caused by the combined effect of sev

With magnetic inspection Magnetic non-destructive testing can only find defects on the surface and near-surface of magnetic cold-drawn pipes, and only qualitative research can be done on the defects,
