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.
