What is the difference and relevance of steel grades and materials of oil pipes and casing?

Relevance: It is an iron ring used to protect the pipe or to facilitate the installation of the pipe.

Difference:

 1, the nature of different: casing is a kind of electric conductor into the electrical equipment or through the wall of an insulating device. Oil pipe is a pipe that transports crude oil and natural gas from the oil and gas layer to the surface after drilling is completed.

2, different specifications: oil pipe specifications: 8-1240 × 1-200mm. casing -0.5%, +1%.

3, different outside diameter: the outside diameter of the oil pipe is generally 60.3 mm to 114.3 mm. Casing outer diameter ± 0.79.

Precautions:

1, must be strictly selected raw materials: steel casing is a kind of engineering parts, it is welded with a water stop ring outside the pipe wall, the water stop ring and the outer pipe wall of the steel pipe casing vertically, the pipe wall is set inside the pipe flange, the pipe flange is vertically connected with the inner pipe wall of the steel pipe casing. Visible, good steel casing is with waterproof function, in the selection of raw materials must pay strict attention to this point, do a good job of waterproof test function, in order to ensure that the selection of raw materials with waterproof.

2, steel casing is a physical class of parts, there is a certain volume, although the precision is not as good as a lot of small parts, but to make the best steel casing must have top technical support.

3, high-quality raw materials coupled with a professional technical team, is not enough to produce steel casing, because this kind of engineering parts must have perfect production equipment to be able to produce successfully.
