  Industrial steel pipe finishing defects and their prevention

  The finishing process of steel pipes is critical for removing defects, improving quality, meeting special product requirements, and defining the "identity" of the products. Key finishing processes include straightening, cutting ends (chamfering, sizing), inspection and testing (surface quality, geometric dimensions, non-destructive testing, hydraulic tests), grinding, length measurement, weighing, painting, printing, and packaging. Steel pipes for special purposes may also undergo surface shot peening, mechanical processing, and anti-corrosion treatments.

  Seamless pipe pressure calculation

  A seamless pipe (SMLS pipe) is a metal pipe manufactured from a single piece of steel billet. The production process involves heating, perforation, rolling, and cooling. Unlike welded pipes, seamless pipes have smooth inner walls, uniform thickness, and can withstand high pressure and high temperatures. The manufacturing process ensures the high quality and reliability of seamless pipes.
