Product Details

Oil Well drilling Seamless Casing Pipe API certified Alloy Steel Tube

Oil casing description:

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

an anti-collapse performance.

Features:

1. Length range R3
2. API 5CT seamless pipe
