Casing Specifications 4 1 2” 20” - China

Oil Casing: An Essential Component in Oil Drilling Oil casing is an indispensable part of the oil drilling process.

It plays a crucial role in supporting the wellbore and preventing collapse, while also providing a stable channel for the extraction of oil and gas.

Currently, the common specifications of oil casing on the market range from 4-1/2 inches to 20 inches, which can meet the needs of wells with different depths and geological conditions.

In the production of oil casing, the design of the thread type is particularly critical.

The STC (Short Round) thread type, which is relatively short and round in shape, is an early widely used type.

It is relatively simple in processing technology, but its strength and sealing performance are relatively weak.

With the development of technology, the LTC (Long Round) thread type has gradually become mainstream.
