Hainan Steel teach you: General Provisions splicing steel engineering components

1, H-beam flange plate welded seam and web spell from the seam, not less than 200mm flange plate splice length should not be less than 600mm;. Web splice width should not be less than 300mm, the length should not be less than 600mm.
2, side splice length box-shaped member should not be less than 600mm, the adjacent sides of the plate to fight from the seam of not less than 200mm; not splice plates in the transverse direction, when the width exceeds 2400mm really necessary splicing, splicing minimum width of not less than 1/4 of the plate width.
3, no special design requirements, hot-rolled steel may be straight mouth full penetration welding splicing, splicing length should not be less than 600mm.
4, take a long time for each pipe section is preferably a connector between the shortest length should be lengthened to fit the following requirements:
(1) When the pipe diameter d≤500mm, should not be less than 500mm;
(2) When the pipe diameter of 500 mm <d≤1000mm, should not be less than the diameter d;
(3) When the pipe diameter d> at 1000mm, should not be less than 1000mm;
(4) When steel pipe rolling method forming, by a number of joint, but the shortest length should be fit to take a long paragraph 1-3 paragraph.
5, take a long pipe, the adjacent pipe section or longitudinal weld pipe sections should be staggered, staggered minimum distance (along arc direction) should not be less than five times the pipe wall thickness, and not the less than 200mm.
6, parts welding seam should fit the design documents, when the design No, you should use full penetration butt welds and other strong. Hainan Steel
