Novel pipe intersecting joint structure
The invention discloses a novel pipe intersecting joint structure. The structure comprises a main pipe, branch pipes and a cushion piece; the branch pipes are welded on the cushion piece; the cushionpiece is connected to the main pipe; the length, along the axial direction of the main pipe, of the cushion piece is greater than or equal to the maximum value, in the axial direction of the main pipe, of the outer envelope line of the welding end surface of each branch pipe; and the length, in the circumferential direction of the main pipe, of the cushion piece is larger than or equal to the maximum value, in the circumferential direction of the main pipe, of the outer envelope line of the welding end face of each branch pipe. Compared with a traditional mode that branch pipes are directly welded to a main pipe, the structure has the beneficial effects that the welding condition of weld joints is improved; meanwhile, loads are transmitted through the cushion piece, and the traditional direct branch pipe transmission is abandoned, so that the problem that stress and deformation of the intersecting portion of the main pipe are large due to stress concentration is solved; the bearing capacity of the main pipe is improved; and the problems that the welding workload is greatly increased due to the measures such as welding longitudinal stiffening ribs between the branch pipes and the main pipe, and between the branch pipes, residual stress is caused by a large number of weld joints, and the windward area is increased are solved.
本申请公开了一种新型管相贯节点结构，包括：主管、支管以及垫件；支管焊接于垫件上；垫件连接于主管上；垫件沿主管轴向的长度，大于或等于支管焊接端面的外包络线在主管轴向的最大值；垫件沿主管周向的长度，大于或等于支管焊接端面的外包络线在主管周向的最大值。较于传统的直接将支管焊接于主管上的方式，改善焊缝施焊条件，同时载荷经垫件进行传递，而不是传统的直接支管传递，避免了受力集中，导致主管相贯部位的应力和变形较大问题，提高了主管的承载能力，从而也避免了在支管与主管之间、支管与支管之间焊接纵向加劲肋等措施导致的大大增加焊接工作量、大量焊缝进一步引起残余应力、增大迎风面积的问题。
