Production process of stainless steel corrugated pipe

Abstract

The invention discloses a production process of a stainless steel corrugated pipe. According to the technical scheme, the production process is characterized by comprising the following steps: a, selecting a welded pipe with an appropriate outer diameter and an appropriate wall thickness and cutting the welded pipe into the appropriate length; b, leveling a welding seam of the welded pipe; c, extruding the middle part of the welded pipe by using a wave beating device to form an arc-shaped spiral groove with concave-convex corrugations, namely a stainless steel corrugated pipe with smooth two ends and corrugations in the middle; d, carrying out annealing treatment on the stainless steel corrugated pipe; e, cutting the two smooth sections of the stainless steel corrugated pipe, and obtaining a proper length; and f, performing pressure test and flaw detection on the stainless steel corrugated pipe to ensure the leakproofness of the pipe wall. When corrugation forming treatment is carried out on the surface of the welded pipe, a smooth section can be reserved and then folded and extruded inwards, so that the smooth sections can be formed at the two ends of the welded pipe, it is guaranteed that the smooth sections and the corrugated pipe are integrally formed, the leakage risk of the stainless steel corrugated pipe is reduced, and the use value is improved.

Description

technical field [0001] The invention relates to the field of manufacturing stainless steel pipes, more specifically, it relates to a production process of stainless steel corrugated pipes. Background technique [0002] The traditional method of condenser tube is to use copper light tube with good thermal conductivity, which not only increases the product cost, but also has problems such as poor corrosion resistance, poor impact resistance, low surface strength and hardness, easy vibration, and easy scaling. Therefore, at present, stainless steel bellows are used instead of steel bare pipes, but the smooth sections at both ends of the existing stainless steel bellows are welded later, and there is more risk of leakage. [0003] Therefore, a new solution needs to be proposed to solve this problem. Contents of the invention [0004] The object of the present invention is to provide a production process of stainless steel bellows in order to solve the above problems. [0005...
