Abstract
The invention discloses a kind of anticorrosive anti-wear steel tube manufacture technique, the anticorrosive anti-wear steel tube manufacture technique is comprised the following steps：A, cleaning by degreasing and blasting treatment are carried out to steel pipe internal-surface；B, by cemented carbide powder load steel pipe in and vacuumized；C, heating is carried out to steel pipe cemented carbide powder is melted on steel pipe inner wall, then carry out water-cooled；D, steel pipe is carried out temper eliminate residual stress.A kind of anticorrosive anti-wear steel tube manufacture technique of the present invention, by by cemented carbide powder load steel pipe in and being vacuumized can make cemented carbide powder stick to steel pipe inner wall, cemented carbide powder is melted on steel pipe inner wall by steel pipe carrying out heating again just can quickly form anticorrosive anti-wear alloy-layer, the method is not simple using only equipment, and production technology is shorter, excellent product performance.
Description
Technical field
The present invention relates to a kind of steel tube manufacture technique, more particularly to a kind of anticorrosive anti-wear steel tube manufacture technique.
Background technology
Conveying for severe corrosive, abrasive media generally needs to use the steel pipe of anticorrosive anti-wear performance high, traditional steel tube manufacture technique is typically in the spraying of its inner surface or spray weld alloy powder coating, but required equipment and manufacturing process are all complex, and production cost is higher.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of anticorrosive anti-wear steel tube manufacture technique that use equipment is simple, manufacturing cost is relatively low.
In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that：
A kind of anticorrosive anti-wear steel tube manufacture technique, comprises the following steps：A, cleaning by degreasing and blasting treatment are carried out to steel pipe internal-surface；B, by cemented carbide powder load steel pipe in and vacuumized；C, heating is carried out to steel pipe cemented carbide powder is melted on steel pipe inner wall, then carry out water-cooled；D, steel pipe is carried out temper eliminate residual stress.
Preferably, cemented carbide powder is self-fusible alloy powder of nickel-base in the step B.
Preferably, steel pipe heating-up temperature is 1200-1300 degrees Celsius in the step C.
Preferably, steel pipe temperature is 500-560 degrees Celsius in the step D.
Compared with prior art, a kind of anticorrosive anti-wear steel tube manufacture technique of the present invention, by by cemented carbide powder load steel pipe in and being vacuumized can make cemented carbide powder stick to steel pipe inner wall, cemented carbide powder is melted on steel pipe inner wall by steel pipe carrying out heating again just can quickly form anticorrosive anti-wear alloy-layer, the method is not simple using only equipment, and production technology is shorter, excellent product performance.
