P110 Alloy Steel Grade Casing Pipe With Wall Thickness 5.21mm-16.13mm NDC Test
Oil casing pipe descriptions:
API 5CT casing is inserted into a well bore and cemented in place to protect both subsurface formations
and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place.
The cost of casing is a major part of the overall well cost, so selection of casing size, grade, connectors,
and setting depth is a primary engineering and economic consideration.
Features:
1. Special alloy steel
2. Steel grades J55 K55 N80 L80 P110; L80-13Cr, P110-13Cr, Super 13Cr
3. PSL1, PSL2
4. Length range R3
5. API 5CT seamless pipe
