    What is the difference between straight seam steel pipe and spiral steel pipes

    First: welding process In terms of the welding process, the welding methods of spiral steel pipes and straight seam steel pipes are the same, but straight seam steel pipes will inevitably have many T-shaped welds, so the probability of welding defects is also greatly increased, and the welding re...

    Introduction to methods of rust removal from spiral steel pipes

    1. Sandblasting and rust removal method: Sandblasting and rust removal uses a high-power motor to drive the sandblasting blades to rotate at high speed so that abrasives such as steel sand, steel shots, iron wire segments, and minerals can sandblast the surface of the steel pipe under the effect ...

  • Differences and uses of seamless steel pipes and spiral welded pipes

    Differences and uses of seamless steel pipes and spiral welded pipes

    1. Seamless steel pipes are widely used. General-purpose seamless steel pipes are rolled from ordinary carbon structural steel, low alloy structural steel, or alloy structural steel. They have the largest output and are mainly used as pipes or structural parts for transporting fluids. 2. They are...

  • Methods for cleaning steel pipes in natural gas pipelines that transport oil, gas, and water together

    Methods for cleaning steel pipes in natural gas pipelines that transport oil, gas, and water together

    In the long-term use of natural gas steel pipelines, liquid accumulation in the pipeline and corrosion of the inner wall will occur during the long-term operation of the two-phase flow pipeline. These liquids accumulate at the low points of the pipeline, causing the pressure drop of the pipeline ...

  • How to distinguish welded steel pipes and seamless steel pipes

    How to distinguish welded steel pipes and seamless steel pipes

    1. Metallographic method: The metallographic method is the main method to distinguish welded steel pipes and seamless steel pipes. High-frequency resistance welded steel pipes do not add welding materials, so the weld seam in the welded steel pipe is very narrow. If the method of rough grinding a...
