Abstract
The invention discloses a kind of steel pipe inner wall surface defect processing method, the steel pipe inner wall surface defect processing method is comprised the following steps：A, penstock installation is made into steel pipe rotary on whirler, while setting a vibrating mechanism makes penstock vibration；B, to steel pipe inner wall spray high-pressure water jet, abrasive particle is contained in high-pressure water jet；C, purged and dried to being passed through dry gas in steel pipe.A kind of steel pipe inner wall surface defect processing method of the present invention, by penetrating high-pressure water jet and abrasive particle to the steel tube inner spray for rotating and vibrate, steel pipe inner wall surface can be made to be subject to erosion and shearing, so as to fast and effeciently steel pipe inner wall surface defect be removed, the method is simple using equipment, and production efficiency is higher and environment friendly and pollution-free.
Description
Technical field
The present invention relates to a kind of manufacture of steel pipe, more particularly to a kind of steel pipe inner wall surface defect processing method.
Background technology
In the fabrication process often there is the defects such as crackle, scar, roughness be big in its inner wall surface with steel pipe, subsequent handling and final product quality are influenced whether if processing not in time, current processing method mainly has pickling, shot-peening etc., but it is larger more complicated all to there is equipment, environmental pollution is big, low production efficiency, manufacturing cost grade high is substantially not enough.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of production efficiency steel pipe inner wall surface defect processing method high, environment friendly and pollution-free.
In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that：
A kind of steel pipe inner wall surface defect processing method, comprises the following steps：A, penstock installation is made into steel pipe rotary on whirler, while setting a vibrating mechanism makes penstock vibration；B, to steel pipe inner wall spray high-pressure water jet, abrasive particle is contained in high-pressure water jet；C, purged and dried to being passed through dry gas in steel pipe.
Preferably, steel pipe rotary rotating speed is 1000-1400 rpms in the step A.
Preferably, the step B mesohighs water jet pressure is 6-10MPa.
Preferably, abrasive particle is quartz sand in the step B.
Preferably, the particle diameter of abrasive particle is 80-100 mesh in the step B.
Compared with prior art, a kind of steel pipe inner wall surface defect processing method of the present invention, by penetrating high-pressure water jet and abrasive particle to the steel tube inner spray for rotating and vibrate, steel pipe inner wall surface can be made to be subject to erosion and shearing, so as to fast and effeciently steel pipe inner wall surface defect be removed, the method is simple using equipment, and production efficiency is higher and environment friendly and pollution-free.
