Difference between A series and B series of ssaw pipe

When designing and selecting pipes, the nominal diameter DN is usually used to identify the diameter of the pipe. However, in the actual procurement and use process, the same nominal diameter correspo

Austenitic stainless steel pipe

Austenitic stainless steel pipe refers to stainless steel with austenitic structure at high temperature and normal temperature. When steel contains approximately 18% Cr, 8%~10% Ni, and approximately 0

Differences in performance between SSAW pipe and LSAW pipe

Spiral welded pipe: It is made by rolling low-carbon carbon structural steel or low-alloy structural steel strip into a pipe blank at a certain spiral angle (called forming angle), and then welding th

Advantages and Disadvantages of Using Spiral Pipes in Natural Gas Pipelines

Spiral pipes for gas pipelines have the advantages of strong corrosion resistance, easy installation and maintenance, economical and practical, safe and reliable. It is one of the commonly used pipeli

Internally threaded galvanized pipe

The structure of internally threaded galvanized steel pipe consists of two parts: pipe body and thread. The pipe body is made of welded steel pipe, and the threads are internal threads machined on the

Fin tube production process

Fin tubes are made of fins of the same material or different materials wrapped around a base tube. They are currently a more effective and efficient heat exchange element. Fins are usually added to th

Preheating techniques for alloy steel pipes before welding

The preheating of alloy steel pipes is to make the internal structure of the steel reach a more stable state, thereby improving the quality of the weld. At the same time, it can also reduce the stress

Common connection method for stainless steel fluid pipes
