Tubing And Casing

We can provide various steel grade quality tubing with size range from 2-3/8 to 4-1/2, casing with size range from 4-1/2 to 18-5/8 and wall thickness from 0.19in to 0.27in for tubing, from 0.205in to 0.595in for casing in compliance with API Spec 5CT & API Spec 5B. We Are positively importing and self developing Thread Seal Configuration with independent intellectual property rights and casing to meet demands of users from home and abroad.

 
 
Technical specification for tubing and casing
Delivery status:
As hot rolled and heat treated,
Delivery standard:
API Spec 5CT, Specification for Casing and Tubing; Q/ML002-2007, Specification for High Collapse Grade Casing. Q/ML003-2007, Specification for Anti-corrosive Tubing and Casing.
Usage:
Tubing is used to pump oil or gas. Casing is used as wall of oil or gas well.
Features:
Purified steel; stable chemical composition; good quality surface; high accuracy dimension (Accu-Roll tube rolling mill is also called as accurate tube rolling mill, at present, it is the most accurate of all the tube rolling mills), perfect mechanical properties and workman-ship are products virtues.
