Description

Technical Field

[0001] This utility model relates to the field of pipe fittings, and in particular to a welded pipe with friction embossing on its outer surface. Background Technology

[0002] Welded steel pipes, also known as welded tubes, are steel pipes made by rolling and welding steel plates or strips. The production process of welded steel pipes is simple, efficient, and offers a wide variety of specifications with low equipment investment, but their strength is generally lower than that of seamless steel pipes. The general production process for welded pipes is as follows: raw material uncoiling—leveling—end shearing and welding—looping—forming—welding—removal of internal and external weld beads—pre-correction—induction heat treatment—sizing and straightening—eddy current testing—cutting—hydraulic pressure testing—pickling—final inspection (strict quality control)—packaging—shipping.

[0003] However, welded pipes are generally used as support and reinforcement components, and their surfaces are smooth. The smooth surface makes it difficult for welded pipes to meet the work requirements when clamping, protecting, or stacking them, requiring the use of matching parts to complete the task, which reduces work efficiency.

[0004] This utility model provides a welded pipe with friction embossing on its outer surface, which can improve the surface friction of the welded pipe by setting friction texture on the outer side of the welded pipe. It is used in the fields of welded pipe clamping, protection, stacking, etc. The welded pipe consists of inner and outer welded pipes welded together, and has good protective performance.

The outer welded pipe is welded and fixed to the outside of the inner welded pipe. Multiple rings of friction embossing are processed on the outer surface of the outer welded pipe. The multiple rings of friction embossing are arranged horizontally on the outer welded pipe with intervals between them. Each ring of friction embossing has multiple raised friction stripes, and the friction stripes surround the outer surface of the outer welded pipe. The friction stripes are spaced apart from each other, and the spacers are concave grooves. The outer surface of the friction stripes is also provided with pressed embossing.

[0007] In a preferred embodiment of this utility model, the outer welded pipe is thicker than the inner welded pipe, and both the inner welded pipe and the outer welded pipe are steel pipes that are open at both ends and hollow inside.
