API 5CT Anti-Corrosion 2 3/8 J55 EXPE coating Tubing and Casing Coupling

Product Description

Shengji manufacture the tubing and casing coupling with more than 20-year production enperience, we can make EUE and NUE coupling, strictly comply with API 5CT/5B standard, the annual production capacity is 1,000,000 pcs.

The EXPE coating Tubing and Casing Coupling has good corrosion resistance and is used in combination with the HDPE liner tubing. It is widely used in high corrosion Wells.Shengji liner tubing are repair-free thereby extending performance 4.7 times. This reduces maintenance costs. All HDPE/EXPE liner tubing must pass strict quality inspection to guarantee 100% customer satisfaction. Shengji uses an advanced defect detection machine.
