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:

Casing is an electric conductor used in electrical equipment or through the wall of an insulating device. An oil pipe is used to transport crude oil and natural gas from the oil and gas layer to the surface after drilling is completed.

The specifications for oil pipes are 8-1240 × 1-200mm, while casing has a tolerance of -0.5%, +1%.

The outside diameter of oil pipes is generally between 60.3 mm and 114.3 mm, while casing has an outer diameter tolerance of ± 0.79mm.

Precautions:

The steel casing used must be made from strictly selected raw materials. It is an engineering part that consists of a pipe wall welded with a water stop ring on the outside. The water stop ring is positioned vertically with respect to the outer pipe wall of the steel pipe casing. Inside the pipe wall, a pipe flange is set, which is vertically connected to the inner pipe wall of the steel pipe casing. The steel casing must have a waterproof function, so it is important to select raw materials carefully and conduct thorough waterproof testing.

As a physical component, the steel casing has a certain volume and requires top technical support to ensure the best quality.

High-quality raw materials and a professional technical team are not enough to produce steel casings. This type of engineering part requires perfect production equipment for successful production.
