Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment of the high bending resistance welded pipe convenient for fixing is as follows:

referring to fig. 1-4, a high bending resistance welded pipe convenient for fixing includes a pipe body 1, a snap ring 2 fixedly connected to the outside of the pipe body 1, the pipe body 1 and the snap ring 2 are corresponding in position and matched in specification, and the snap ring 2 and the pipe body 1 are fixedly connected by bolts.

The outside fixedly connected with extension board 3 of snap ring 2, the corresponding and specification phase-match in position of extension board 3 and snap ring 2, the design of square is adopted to 3 appearances of extension board, can effectively prevent through positive direction extension board 3 that body 1 from moving in welding process and transport transportation to make welded tube manufacturing more stable and high-efficient, improved welded tube welding seam welding quality, improved the quality of welded tube.

The surface of extension board 3 has been seted up through-hole 4, the inboard swing joint of through-hole 4 has energy-absorbing pole 5, the outside swing joint of energy-absorbing pole 5 has swivel nut 6, the diameter of through-hole 4 is greater than the specification diameter of energy-absorbing pole 5, swivel nut 6 passes through threaded connection with energy-absorbing pole 5, swivel nut 6 corresponds and the specification phase-match with the position of extension board 3, the quantity of energy-absorbing pole 5 is four, all energy-absorbing pole 5 circular equal angular distribution is in the outside of extension board 3, make energy-absorbing pole 5 and extension board 3 fixed connection through swivel nut 6 rotation, thereby make the stress concentration that the boat welded tube produced at processing handling process absorbed by energy-absorbing pole 5, the bending resistance characteristic of welded tube has been improved effectively, the manufacturing and the structural strength who uses of welded tube have been improved.
