Description
Technology field
The present invention relates to a kind of stainless steel pipes production procedure, belong to pipeline production technical field.
Background technique
In recent years, thin-walled stainless steel tube has obtained increasingly being widely applied in many industries such as chemical industry, medicine, light industry, uses
Various stainless steel hot-rollings, cold rolling stainless steel tube is widely used in the stainless steel knot of oil, chemical industry equipment pipeline and various uses
Structure part, it is all to ensure that the water pressure test is qualified as the steel pipe for bearing Fluid pressure except should ensure that chemical composition and mechanical performance,
In recent years, developed to cavitation direction with mitigating the Axle Parts of weight, these hollow parts are in tube axial direction variation in diameter shape
Shape is more, but tube reducing phenomenon occurs because tube outer diameter is smaller than mold for molding position internal diameter, but this method meeting for mitigating weight
Occur rupture, and surface spikes phenomenon.
The content of the invention
Goal of the invention：In order to overcome the rupture embathed, and surface spikes problem, the present invention provides a kind of stainless steel pipes
Production procedure
Process program：The present invention discloses a kind of stainless steel pipes production procedure, comprises the following steps：
The first step：Inspection raw material, the raw material are stainless steel tube；
Second step：The stainless steel tube mark that will be verified is marked；
3rd step：Stainless steel tube is mechanically polished, is polished flat stainless steel pipe surface is rough, then cleaned；
4th step：By stainless steel tube electrobrightening, stainless steel tube is put into electrolytic cell, passes to direct current ionization reaction and produced
The anodic solution of selectivity, trickle burr is removed by stainless steel pipe surface；
5th step：By the shaping equating of stainless steel tube port, then it is passivated, HNO3 liquid is used to acid-washing stainless steel passivation,
Corrosion inhibiter such as Lan-826,93 DEG C of temperature, time 6h, temperature：121 DEG C, time：6h, then with hot water injection and immerses 10mg/L
In ammonium hydroxide+100mg/L hydrazines；
6th step, drying is cleaned by the stainless steel tube after passivation, then checks size；
7th step：Stainless steel tube after the assay was approved, is put into 100 grades of dust free room, is cleaned with pure water and dried up, diseases caused by external factors inspection after drying
Test, surface roughness is checked, oil content inspection；
8th step：After the assay was approved dust free room pack, double casing, it is interior vacuumize, be finally put in storage.
Procedure of processing of the present invention is simple, and the product external surfaces light for processing is smooth, and light weight, than traditional steel pipe more
Easily carry.
Further, during the electrobrightening electrolytic cell using sulfuric acid, phosphoric acid, hydrofluoric acid and it is sweet be electrolysed, so
Layer protecting film can be formed in stainless steel pipe surface by grease.
