Problems and Defects of ERW Steel Pipe

Problems and Defects of ERW Steel Pipe: Process defects , Weld defects and Surface defects.

Technology of Seamless Steel Tube Production

General seamless steel tube production process can be divided into cold drawing and hot rolled, cold rolled seamless steel tube production process generally more complicated than hot rolled.

Technology of straight seam high frequency resistance welded steel pipe

Factors that affect the raw material for the steel pipe welding quality affect the quality of raw materials are mainly steel mechanical properties unstable surface defects and strip geometry deviation big three aspects, therefore, we should focus on these three aspects of control.

Production Process of Seamless Steel Pipe

Production and market of copper powder and copper alloy powder

Foreign industrial copper powder production began in the 1920s. At that time, the main production processes are electrolysis and oxidation-reduction method. After 1950s, the replacement precipitation, water treatment method and atomization production process emerge.

What Equipment does the Sausage Production Line Need?

What equipment is needed for the sausage production line? Different regions have different tastes. The production of sausages is based on the different output of users. It is not enough to rely on one kind of equipment.

Production process of nonwoven bags

Nonwoven bags are generally used screen printing technology, which is commonly known as "silk", and this is a lot of manufacturers have been commonly used printing technology. Generally it's printed by human being, so the color control on the technology control is not easy, therefore, there are many new non-woven printing ways come up.

The Study on Inspection Method Of Seamless Steel Tubes

There are many kinds of detection methods for non-destructive testing, for the surface defects are eddy current, magnetic flux leakage, magnetic powder, penetration and visual, etc., you can use ultrasound, ray, etc. for internal testing, the latest sound emission, acoustic holography, far infrared, nuclear magnetic resonance and electromagnetic ultrasound and other means.

Hot Tension Reducing Steel Pipe

Due to restrictions by its production process, seamless steel pipe production costs have been high, resulting in the gradual decline of its economic benefits. As technology advances China's metallurgical industry, new products instead of seamless steel pipe hot stretch reducing began to emerge.

The clothing customized has became more and more popular in the fashion trend

Advantages and Disadvantages of Straight Seam Steel Pipe

Straight seam steel pipes can be divided into high frequency straight seam steel pipes (ERW Pipe) and submerged arc welded straight seam steel pipes (LSAW Pipe) according to the production process.

Difference of LSAW and SSAW

This artical will explain the difference of LSAW and SSAW in many aspects.
