A, according to the provisions of GB14975-94< stainless steel seamless steel pipe steel pipe length >,

 

usually (not length) of hot-rolled steel 1.5 ~ 10m, hot extruded steel pipe is equal to and greater than 1m.

 

cold drawing (rolling) steel pipe wall thickness of 0.5 ~ 1.0mm, 1 ~ 7m; the wall thickness is greater than

 

1.0mm, 1.5 ~ 8m.

 

B, hot rolling (hot extrusion) pipe diameter of 54 ~ 480mm is 45; the wall thickness is 4.5 to 45mm. A total

 

of 36 kinds of cold drawing (rolling) steel pipe diameter of 6 ~ 200mm is 65; the wall thickness is 0.5 to

 

21mm a total of 39.

 

C, both inside and outside the pipe surface shall not have cracks, folding, cracking, crack, rolling

 

reduction, there is separation and scab defects, these defects should be completely removed (except for

 

machining tube), after the removal of the outer wall thickness and shall not exceed the negative

 

deviation. Where does more than allow negative deviation of the minor surface defects can he not clear.

 

D, straight allows depth. Hot rolling, hot extruded steel pipe, the diameter is less than or equal to 140mm

 

less than 5% of the nominal wall thickness, the maximum depth of not more than 0.5mm; cold drawing

 

(rolling) steel is not greater than 4% of the nominal wall thickness, the maximum depth of not more than

 

0.3mm.

 

E, the pipe ends should be cut at right angles, and remove the burr. The manufacturing process of

 

stainless steel seamless pipe: 1 hot-rolled (extrusion seamless pipe): billet, heating, perforation, three roll

 

cross rolling tube, rolling or extrusion, tube, diameter (or reducing), cooling, straightening, pressure test

 

(or testing), marking, raw materials storage rolling seamless pipe is round billet, embryo after cutting

 

machine cutting the growth of about 1 meters of the blank pipe, and the conveyor belt to the furnace

 

heating billet is fed into the heating furnace,

 

The temperature is about 1200 degrees Celsius. The fuel is hydrogen or acetylene. The furnace

 

temperature control is the key problem. Round billet released after pressure punch through the air. Are

 

generally more common puncher piercer, this machine has high production efficiency, good product

 

quality, hole diameter enlargement, can wearing a variety of steels. After perforation, round tube has

 

been three roll cross rolling, rolling or extrusion. The extrusion to take off pipe sizing sizing machine.

 

Through the high-speed rotation of the cone drill into the billet punch forming tube. Pipe diameter by

 

sizing machine drill diameter length to be determined after sizing steel tube. And enter the cooling tower,

 

the water cooling pipe, after cooling, it is necessary to straightening.

 

Pipe by straightening by the conveyor belt to the metal detector (or hydrostatic test) for internal

 

inspection. Steel pipe internal cracks, bubbles and other problems will be detected even after the pipe

 

quality inspection. Through the strict quality inspection of steel pipe manual selection. After using spray

 

paint on the number, size, production batch. And by crane into the warehouse.

 

2 cold drawing (rolling): seamless steel billet, heating, perforation, head, annealing, pickling, oil pipe

 

(copper), multi pass drawing (cold rolling) to the tube, heat treatment, straightening, pressure test

 

(testing), marking and warehousing. Cold drawing (rolling) method for rolling seamless steel pipe than

 

hot-rolled (extrusion seamless pipe) complex. Their production process is basically the same.

 

The first three steps are different from the beginning of the fourth steps, the circular tube was empty to

 

begin, annealing. After annealing and pickling to use a special acidic liquid. After acid pickling oil. Then

 

followed by a multi pass drawing (Leng Zha) and the blank pipe, specialized heat treatment. After heat

 

treatment, it is necessary to straightening.

 

Pipe by straightening sent by conveyor metal detection (or machine Hydrostatic test) internal testing.

 

Steel pipe internal cracks, bubbles and other issues, will be detected. But also through strict quality

 

inspection of steel pipe quality inspection manual selection. After using spray paint on the number, size,production batch. And by crane into the warehouse
