13 3/8" P110 Steel Grade Seamless Casing Pipe For Oil And Gas Well
Oil casing pipe descriptions:
Oil casing is a large diameter seamless pipe that is assembled and inserted into the drilled section of
the borehole and typically held into place with cement.
Puyang Zhongshi Group provide various seamless casing from 4-1/2’’-20’’ with steel grade J55,K55,
N80,L80,P110 etc. The Casing pipe length range is R1,R2,R3, with threads of BTC, LTC, STC.
According to the strength of steel, casing pipe steel can be divided into different steel grades. Different
steel grade is used in oil well with different well depth. In corrosive environment also requires the casing
itself has corrosion resistance. In the complicated geologic condition place also asked the casing
having a anti-collapse performance.
Features:
1. Alloy steel seamless pipe
2. Length range R3
