Casing Pipe
Casing Pipe
A casing pipe is a specialized large-diameter pipe lowered into an open hole and cemented in place. Our casing pipes are available in standard API configurations, with all sizes from 4-1/2" to 20" in grade J55, N80, L80, C90, P110 and Q125. They are strictly made in accordance with API Specification 5CT, API Specification 5B and others. However, their steel yield strength is higher than API standard. Additionally, our casing pipes provide high thread bonding strength with good anti-thread gluing ability.
