2, a box-shaped member side splice length of not less than 600mm, the adjacent sides of the plate seam pitch of not less than 200mm; not splice plates in the width direction, when the width exceeds 2400mm really necessary splicing, the minimum width should not be spliced 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 a length of not less than 600mm.
4, take a long time for each pipe section is preferably a fitting room, take long length minimum should meet the following requirements:
(1) When the pipe diameter d≤500mm, not 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, not less than 1000mm;
(4) When steel pipe rolling manner forming, by a number of joint, but the shortest length to take a long paragraph shall comply with the requirements of paragraph 1 to 3.
