Title:
PRODUCTION METHOD FOR ARCH-SHAPED CORRUGATED STEEL PLATE WALL OF ASSEMBLY-TYPE STEEL STRUCTURE PIPE RACK
Document Type and Number:
WIPO Patent Application WO/2021/022808
Kind Code:
A1
Abstract:
Disclosed is a production method for an arch-shaped corrugated steel plate wall of an assembly-type steel structure pipe rack. By means of first welding corrugated steel plates of an assembly-type steel structure pipe rack and then bending same into an arch shape, the overall camber and the gradient of two end faces of the corrugated steel plates are consistent, thereby facilitating assembly and welding of flanges. The method can avoid the nonuniformity of welding seams of contact faces and difficulty in welding due to inconsistent inclination angles of the end faces of the corrugated steel plates during flange welding.
