Embodiment Construction

[0013] Such as figure 1 , figure 2 and image 3 , a reinforced stainless steel pipe with simple connection, consisting of a head 1, a pipe body 2 and a ring 3, the ring 3 is located at both ends of the pipe body 2, and the head 1, pipe body 2 and ring 3 are of an integrated structure , The outer ring of the head 1 is provided with threads, and the inner ring of the bottom of the pipe body 2 is provided with threads matching the head 1. The end-to-end connection of the stainless steel pipe is threaded connection, which has a simple structure, reliable connection, and convenient assembly and disassembly, which provides great convenience for maintenance and replacement.

[0014] The outer surface of the pipe body 2 is coated with a layer of 0.4-0.6mm zirconium nitride layer 5, and the outer surface of the zirconium nitride layer 5 has lines. The zirconium nitride layer 5 protects the pipe body 2, and the zirconium nitride layer 5 with lines on the outer surface can increase t...

Abstract

The invention relates to the technical field of stainless steel pipes, in particular to a reinforced simple connection type stainless steel pipe. The reinforced simple connection type stainless steelpipe is composed of a head, a pipe body and circular rings, wherein the circular rings are positioned at the two ends of the pipe body, the pipe body and the circular rings are of an integrated structure, threads are arranged on the outer ring of the head, and threads matched with the head are arranged on the inner ring at the bottom of the pipe body. According to the reinforced simple connectiontype stainless steel pipe, the design structure is simple, the use is convenient, the practicability is high, the damage to the stainless steel pipe caused by heat treatment is avoided, moreover, dismounting is convenient, and great convenience is provided for overhauling and replacing.

Description

technical field [0001] The invention relates to the technical field of stainless steel pipes, in particular to a reinforced stainless steel pipe with simple connection. Background technique [0002] Stainless steel pipe is a hollow long round steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures, and is also commonly used as furniture and kitchen utensils. The connection between stainless steel pipes is usually welded, and the welding quality cannot be guaranteed, which may cause rework or seal failure, and there is also a problem of corrosion resistance degradation at the weld. Contents of the invention [0003] In order to overcome the shortcomings of the existing stainl...
