  • Some Tips for Preventing Steel Pipeline Corrosion

    Some Tips for Preventing Steel Pipeline Corrosion

    Corrosion of pipes occurs because metals are sometimes susceptible to chemical reactions that weaken them. Once the metal is weakened, it is prone to rust and can form cracks and holes, which is a big problem. Corrosion protection for pipes is therefore critical, not least bec...

  • Causes of rust and corrosion of spiral steel pipe

    Causes of rust and corrosion of spiral steel pipe

    Because spiral steel pipes are stacked outdoors, and most of them are buried in the ground when they are in use, they are easy to corrode and rust. To ensure the smooth flow of the pipes, spiral steel pipe manufacturers must have strong corrosion resistance. Once the pipeline ...

  • The difference between thin-walled spiral steel pipe and thick-walled spiral steel pipe

    The difference between thin-walled spiral steel pipe and thick-walled spiral steel pipe

    The concept of thin-walled spiral steel pipe: the strip steel is fed into the welded pipe unit, rolled by multiple rollers, the strip steel is gradually rolled up to form a circular tube billet with an opening gap, and the reduced amount of the extrusion roller is adjusted to ...
