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.
1.Packing :3 layers of packaging, kraft paper inside, water plastic film in
the middle, the outermost GI steel plate tied with steel belt or as
required.
