  • According to the manufacturing method, steel pipes can be divided into two categories: seamless steel pipes and welded steel pipes. Of these, ERW pipes are the main variety of welded steel pipes. Today, we are discussing two types of steel pipe used as raw material f...
  • ERW pipe is made by rolling metal and then welding it longitudinally along its length. Seamless pipes are made by extruding the metal to the desired length; therefore, ERW pipes have welded joints in their cross-section, while seamless pipes do not have any joints in...
  • Spiral pipe conveying fluid can be in accordance with seasonal changes, to take reasonable on and off cooling tower operating fan and pump room used to cool the work of the axial fan measures, effectively reducing the electricity consumption. In due to the steelmakin...
  • Welded pipe to be divided from the production process, and divided into: spiral submerged arc welding pipe SSAW (Spirally Submerged Arc Welding); LSAW pipe(LongitudinallySubmerged Arc Welding); resistance welded pipe ERW (Electric Resistance Welding) three.The next w...
  • Seamless pipe is a long piece of steel with a hollow cross-section and no peripheral seams. In total, more than 5,100 plants under more than 1,850 companies in more than 110 countries produce seamless pipes worldwide, including more than 260 plants under more than 17...
