Description

Technical Field

[0001] The utility model relates to the field of welded pipes, in particular to a welded pipe with welded protection ports at both ends. Background Art

[0002] Welded steel pipes, also known as welded pipes, are steel pipes made by welding steel plates or strips after coiling. The process flow of welded pipes is raw material uncoiling - leveling - end shearing and welding - loop - forming - welding - removal of internal and external bead - pre - correction - induction heat treatment - sizing and straightening - eddy current testing - cutting - hydrostatic inspection - pickling - final inspection (strict control) - packaging - shipping.

[0003] Classified by use, they are further divided into general welded pipes, galvanized welded pipes, oxygen - blowing welded pipes, wire conduits, metric welded pipes, idler rollers, deep - well pump pipes, automotive pipes, transformer pipes, thin - walled electric - welded pipes, special - shaped electric - welded pipes, scaffolding pipes and spiral welded pipes.

[0004] When traditional welded pipes are used as connecting pipes, they are only used as straight pipe fittings. The two ends of the welded pipe are connected to the connecting objects and fixed, and the connection parts are mostly fixed by welding.

[0005] However, due to the small diameter of some welded pipes, they are prone to deformation under pressure. Especially the pipe bodies at the two ends of the connection parts will be quickly bent and damaged when stressed or pressured.

[0006] Therefore, to solve the above problems, the utility model provides a welded pipe with welded protection ports at both ends. The two ends of the welded pipe body are strengthened and protected by the welded protection ports, and the strength of the two ends of the welded pipe body is improved to resist pressure. One section of the protection port is a frustum - shaped pipe, which uses its inclined body to avoid being pressured. The other end of the protection port is a compression - resistant protection pipe, and the compression - resistant protection pipe is provided with multiple circles of concave rib - groove loops. The opening of the concave rib - groove loops makes the annular outer pipe surface of the compression - resistant protection pipe an irregular strengthening surface, and it is not easy to be damaged when being impacted, squeezed, etc. Summary of the Utility Model

[0007] The main technical problem to be solved by the utility model is to provide a welded pipe with welded protection ports at both ends, which can be used as a connecting pipe fitting. The two ends of the welded pipe body are strengthened and protected by the welded protection ports, and the strength of the two ends of the welded pipe body is improved to resist pressure.

[0008] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a welded pipe with protective ports welded at both ends, including a welded pipe body, openings at both ends of the welded pipe body are opened and connected internally, protective ports are welded on the open ends at both ends of the welded pipe body, the inner end of the protective port is a truncated cone tube, the truncated cone tube is horizontally placed and the bottom surfaces on both sides of the truncated cone tube are open, the interior of the truncated cone tube is hollow and connected to the interior of the welded pipe body, the outer side of the protective port is a pressure-resistant protective tube, and a plurality of circles of concave rib groove ring lines are provided on the annular outer tube surface of the pressure-resistant protective tube, and each circle of the concave rib groove ring line is composed of a plurality of concave rib grooves surrounded by a circular ring.

[0009] In a preferred embodiment of the present invention, the pressure-resistant protection tube is integrally connected with the truncated cone tube to form the protection port, and the diameter of the pressure-resistant protection tube is smaller than the diameter of the truncated cone tube.

[0010] In a preferred embodiment of the present invention, the concave rib grooves on two adjacent concave rib groove loops are arranged in a staggered manner.

[0011] In a preferred embodiment of the present invention, the concave rib grooves are concave in the shape of narrow lines, and the concave rib grooves are all sunken into the outer tube surface of the pressure-resistant protection tube and have a consistent depth of depression.

[0012] The beneficial effects of the utility model are as follows: the utility model is used as a connecting pipe fitting, and the two ends of the welded pipe body are reinforced with protection by welding protective ports, so as to improve the strength of the two ends of the welded pipe body to resist pressure, and one section of the protective port is a truncated cone tube, which utilizes its own inclined body to avoid pressure, and the other end of the protective port is a pressure-resistant protective tube and the pressure-resistant protective tube is provided with multiple circles of concave rib groove ring lines.
