Straight crease welded steel pipe with frosty development measurement is for the accompanying purposes:
(1) To enhance the straight crease submerged bend welded pipe body and pipe end geometric dimensional exactness, so that the pipe body and pipe end measurement, roundness and distance across contrast between the two finishes of the pipe to meet the standard necessities for simple on location welding development.
(2) To decrease the framing and uneven twisting in welding procedure of submerged circular segment welded pipe, diminish the development and welding brought about by leftover anxiety, and enhance its circulation, enhance the general mechanical properties of steel.
(3) The general execution of the steel pipe to direct a complete and compelling examination.
(4) Cold extension likewise enhance the fixing of DSAW steel pipe, particularly for the littler width of the straight crease submerged circular segment welded pipe is more evident part.
Straight submerged curve welded pipe after chilly extension, the pipe body and pipe end breadth will increment by around one percent, distance across, roundness and measurement contrast between the two finishes of the steel pipe are enormously enhanced, the pipe straightness is likewise extraordinarily enhanced, the length is diminished by around 0.5 percent, the divider thickness is lessened by around 0.8 percent. In the advancement of straight crease submerged circular segment welded pipe innovation ought to assess these progressions to decide the width of the pipe plate, length and thickness, and the breadth of the pipe before the expansionFind Article, so as not to extend the distance across of the basic steel pipe does not meet the last necessities and cause inadequate.
