Description

tubing is a relatively small-diameter pipe that is run into a well to serve as a conduit for the passage of oil and gas to the field surface facilities for processing. tubing must be adequately strong to resist loads and deformations associated with production and work overs. further, tubing must be sized to support the expected rates of production of oil and gas.

Process

casing pipe manufacturing process:

steel ingot heating → hydraulic punching → reheating → extension → periodic rolling → reheating → sizing → cooling → straightening → pipe cutting → inspection

1. an annular heating furnace is required for ingot heating;
2. punching and reheating with hydraulic press;
3. the oil casing plant uses a two-roller guide plate extension machine for extension;
4. re-use a disc heating furnace for periodic rolling, and use a non-entry furnace for reheating, cooling, straightening, pipe cutting, and inspection.
