Product Description

Casing pipe is most often used in underground construction projects to encase or protect utility lines from being damaged.
Once a well has been drilled, if it is to become a production well, the well must undergo completion. While drilling a well cuts
through the rock formations and allows drilling engineers to reach the reservoir below, the raw sides of the well cannot support
themselves. Similar to the bones of your spine protecting the spinal cord, casing is tubing that is set inside the drilled well to
protect and support the wellstream.

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.
