Helical steel pipe plant with constant length of straight seam compared to pipe.High production potency, low price and quick growth.Spiral steel pipe plant has higher strength than straight joint pipe, and might turn out welded pipe with larger pipe diameter with narrower billet, or turn out welded pipe with totally different pipe diameter with billet of constant dimension.Therefore, the attachment pipe with smaller diameter principally adopts straight seam welding, whereas the attachment pipe with larger diameter principally adopts spiral welding.The main stress of straight joint pipe is perpendicular to all-time low deviation of the anti-attack ability of the pipe, whereas the spiral steel pipe plant staggers all-time low deviation of the anti-attack ability of the pipe, in order that the upwind of the attachment seam length of the spiral steel pipe plant turns into a bonus.This kind of caliper could be a calipers specially marked with the diameter of the foundation of the external thread and also the diameter of the taper hole of the inner thread.The manipulation is telegraphic, intuitive and proper.In addition, it should be attainable to directly manipulate an extended foot calipers to attach with a steel ruler to live the external diameter, length of the foundation of the external thread, the taper bore diameter of the inner thread and check the thread dimensions.
