Large -sized spiral welded pipe, including tube body made of being rolled as main ribbon spiral, inboard wall of tube body is equipped with the first liner and the
Two liners, the first liner spiral fit in the surface of main steel band, and the width of the first liner is less than the width of main steel band, and second
Liner spiral fits in the spiral-shaped seam formed between adjacent tubes, and the left and right sides difference of the second liner is adjacent thereto
The welding of the first liner, the first liner and the second liner cover entire inboard wall of tube body, and being equipped with section along tube wall spiral is half
The reinforcing ring of closed form forms spiral helicine channel between the reinforcing ring inner wall and tube wall.
Steam in environment is easy to corrode the outer wall of submerged-arc welding steel pipe, and the outer wall of submerged-arc welding steel pipe is caused to be easy to happen corruption
Erosion, and then cause the corrosion resistance of submerged-arc welding steel pipe entirety to reduce, and then reduce the service life of submerged-arc welding steel pipe and use peace
Quan Xing.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of corrosion-resistant submerged-arc welding steel pipe, to reach raising submerged-arc welding
The humidity resistance of the outer wall of steel pipe, and then improve the effect of the corrosion resistance of the outer wall of submerged-arc welding steel pipe.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of corrosion-resistant submerged-arc welding steel pipe, the outer wall of the tube body including hollow tubular, the tube body are enclosed with waterproof layer.
By using above scheme, waterproof layer wraps up the outer wall of the tube body of submerged-arc welding steel pipe, greatly reduces ring
Erosion of the steam to tube wall in border, mitigates the outer wall of tube body there is a phenomenon where corroding, and then it is whole to improve submerged-arc welding steel pipe
The corrosion resistance of body, and then improve the service life and safety in utilization of submerged-arc welding steel pipe entirety.
The utility model is further arranged to: the waterproof layer is the waterproof roll for being layed in the outer wall of tube body.
By using above scheme, the waterproof performance of waterproof roll is good, is capable of the outer wall of effective protection tube body, and laying side
Just, convenient for operation, the production difficulty of submerged-arc welding steel pipe is reduced.
The utility model is further arranged to: the outer wall of the waterproof layer is enclosed with protective layer.
By using above scheme, protective layer can play a protective role to waterproof layer, and external environment is effectively reduced to anti-
The abrasion and destruction of water layer improve the integrity of waterproof layer, and then guarantee that waterproof layer can play waterproof efficacy for a long time.
The utility model is further arranged to: the protective layer is TPU layer.
By using above scheme, TPU have preferable toughness, wearability and elastic deformability, can be good to
Disappear external impacts, so can effective protection waterproof layer be not destroyed.
The utility model is further arranged to: enhancing steel mesh is embedded in the TPU layer.
By using above scheme, enhancing steel mesh can not only play a supporting role to TPU layer, moreover it is possible to improve entire submerged arc
The compressive property and toughness of Coiling Welded Pipe improve safety when transfer oil, natural gas, coal gas and water and certain solid materials.
The utility model is further arranged to: the tube body is SUS444 stainless steel material.
By using above scheme, SUS444 is a kind of ultra-low carbon nitrogen, the ferritic stainless steel containing 18% chromium and 2% aluminium, tool
There is preferable corrosion resistance, cooperates waterproof roll, the corrosion resistance of entire submerged-arc welding steel pipe can be further increased.
In conclusion the utility model has the following beneficial effects:
1, the waterproof layer formed in the outer wall package waterproof roll of the tube body of submerged-arc welding steel pipe, reduces the steam pair in environment
The erosion of tube wall, mitigates the outer wall corrosion phenomenon of tube body, improve the corrosion resistance of submerged-arc welding steel pipe entirety, service life and
Safety in utilization；
2, protective layer is wrapped up in the outer wall of waterproof layer, reduces abrasion and destruction of the external environment to waterproof layer, improves waterproof
The integrity of layer guarantees that waterproof layer can play effect for a long time；
3, enhancing steel mesh is buried in protective layer, can not only be played a supporting role to TPU layer, moreover it is possible to improve entire submerged arc
The compressive property and toughness of Coiling Welded Pipe improve safety when transfer oil, natural gas, coal gas and water and certain solid materials.
