Oil And Gas Well Seamless Casing Pipe High Strength For Oil Industry
Oil casing pipe descriptions:
Puyang Zhongshi Group provide seamless casing from 4-1/2’’-20’’ with steel grade J55, K55, N80, L80,
P110 etc. The Casing pipe length range is R3, with threads of BTC, LTC, STC.
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. Seamless pipe
2. Oil pipe
3. Alloy steel pipe
4. Length range R3
Technical specification:
