          The latest price reference: spiral pipe price list
          Spiral steel pipe to allow the standard deviation range
          GB / 9711.1-1997 standard requirements:
          Outer diameter D <508, negative 12.5% T positive 15% T,
          > 508, negative 10.0% T is 17.5T.
          Standard of the implementation of the standard spiral steel pipe
          SY / T5037-2008 (Ministry superscript, also known as ordinary fluid pipeline with spiral submerged arc welded pipe)
          The main production process of the standard spiral steel pipe
          Uncoiler - Scroll - Leveling - Butt Welding - Milling Edge - Forming - Internal Welding - Outer Welding - Pipe Cutting - Break - Subsequent Welding - Hydrostatic Test
          The main difference between the standard spiral steel pipe and the national standard spiral steel pipe
          1. Use (5037 is a general flow pipe with the pipe; 9711 is the industrial transportation pipe)
          2. Detection method
          3. The performance indicators
          4. The standard GB steel pipe does not allow Q235B material, must be a pipeline steel
          Spiral steel pipe marked the main use of symbols
          D ----- nominal diameter of steel pipe mm
          T ---- nominal wall thickness mm
          M ---- steel pipe mass kg / m
          P - Test pressure of hydrostatic test
          S - Test stress of hydrostatic test
          H ---- welding residual height mm
