How is oil well casing made? Sometimes the well is drilled in stages called a casing program. Here, a well is drilled to a certain depth, cased and cemented, and then the well is drilled to a deeper depth, cased and cemented again, and so on.

No matter which part of the power plant, there will always be water or steam passing through.

Petroleum casing pipes are steel pipes used to support the walls of oil and gas wells to ensure the normal operation of the entire oil well after drilling and completion.

In order to ensure the quality of welding, the processing of the workpiece that needs to be welded before welding can be gas cutting or cutting. Generally, it is a bevel, and sometimes it is a curved surface.

Why the stainless steel pipe need pickling? The stainless steel pipe will form an oxide film when placed in the air, but the protection of this film is not perfect.

The problems and defects of ERW steel pipes are related to raw materials, production methods, process conditions, equipment status and personnel. Product defects that occur in the production process due to the above factors and restrictions.

Application processing technology of seamless steel pipe: 1. Grinding the nozzle of seamless steel pipe: After cutting, the plastic layer of the nozzle should be polished with an angle grinder.

Why does hot-dip galvanized seamless steel pipe cause chromatic aberration? Mainly due to the violent reaction of iron and zinc.

Nowadays, hot-dip galvanized seamless pipe, as a commonly used type of fire-fighting pipeline, plays an irreplaceable role in the field of fire safety due to its high pressure-bearing strength.

The material and type of casing pipe should be selected according to the drilling structure design and engineering needs. Deep-hole core drilling has a long construction period and a large casing depth.
