API 3PE Fbe Spiral Steel pipe

　　Spiral Steel pipe strength is usually higher than the straight seam welded pipe, can produce a narrow billet diameter larger pipe, but also with the same width of the billet production pipe diameter is not the same. Forming process, the deformation of uniform steel plate, the residual stress is small, the appearance does not scratch. Processing spiral steel pipe in diameter and wall thickness scale standard scale has greater flexibility, especially in the production of high-grade thick-walled thick-walled tubes, especially in small and medium-sized thick-walled tube has other technology incomparable advantages, can be satisfied Users have more requests for API 3PE Fbe Spiral Steel pipe standards.
