Abstract
The invention relates to the technical field of steel pipes, and particularly relates to a manufacturing method of a steel pipe. The manufacturing method comprises the following stages of: (1) a pretreatment stage, i.e., a workpiece is subjected to treatments through oil removing, rust cleaning, phosphorization and passivation processes; (2) an electrostatic coating stage, i.e., an electrostatic coating machine is utilized to spray a powder coating on the surface of the workpiece after pretreatment; (3) a high temperature solidifying stage, i.e., the sprayed workpiece is pushed into a curing oven, wherein the heating temperature is 170-190 DEG C, and the heat preservation time is 10-20 minutes; (4), an end product forming stage, i.e., the workpiece is taken out from the curing oven after high temperature solidification, and the end product is obtained after cooling. The manufacturing method provided by the invention has the advantages that the process is simple, the operation is convenient, the time and temperature are easy to control and master, the end product has the extremely high corrosion resistance, compression resistance and ageing-resistant performance, the service life is prolonged, and the actual use requirement is met.
Description
Technical field
The present invention relates to the technique of pipe field, be specifically related to the production method of steel pipe.
Background technology
At present, the steel pipe sold on the existing market is through after the simple surface treatment, and it is corrosion-resistant, compression resistance, ageing-resistant performance are lower, can not satisfy actual user demand.And existing steel tube surface complex treatment process, time, temperature are all wayward.
Summary of the invention
The purpose of this invention is to provide that a kind of technique is simple, easy to operate, time, temperature are easy to control and the production method of corrosion-resistant, compression resistance, steel pipe that ageing-resistant performance is high.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: the production method of steel pipe comprised with the next stage:
(1), pretreatment stage, workpiece is processed through oil removing, rust cleaning, phosphatization and passivation procedure;
(2), the electrostatic spraying stage, utilize electrostatic sprayer that powdery paints is sprayed on the surface of the described workpiece after the pre-treatment;
(3), the hot setting stage, the described workpiece that spraying is good is pushed in the curing oven 170~190 ℃ of heating-up temperatures, temperature retention time 10~20 minutes;
(4), finished product, the workpiece behind hot setting is taken out in blow-on, cooling namely obtains finished product.
The present invention has following beneficial effect: the production method of steel pipe of the present invention, mainly comprise pretreatment stage, electrostatic spraying stage and hot setting stage, and get at last finished product; Technique of the present invention is simple, easy to operate, time, temperature all are easy to control and grasp, and its finished product has high corrosion-resistant, compression resistance, ageing-resistant performance, has prolonged service life, satisfies actual user demand.
The specific embodiment
Below the present invention will be further described in detail.
