How to avoid thermal expansion and thermal deformation of carbon steel pipes at high temperatures?
Carbon steel pipes are prone to thermal expansion and thermal deformation at high temperatures, which can lead to leaks at pipe connections or damage to the pipe itself. Here are a few ways to avoid this: 1. Choose the right pipe support Proper pipe support can help the pipe bear the weight and l...Read more -
How to distinguish the normal floating rust and rust of seamless steel tubes?
Seamless tubes (SMLS) are cut into sections by steel mills, and then heated in an annular furnace-perforated-sizing-straightening-cooling-cutting-packed to become qualified finished products, which generally cannot be placed in the production workshop of the user. With so many stocks in stock, de...Read more -
