API 5CT 3 1/2 HDPE Liner Tubing Seamless Steel Pipe

API 5CT HDPE  Liner Tubing Pipe 

Shengji is the leading manufacturer of HDPE/EXPE liner tubing in China. HDPE/EXPE liner tubing reduces the coefficient of friction between sucker rod and tubing. By adopting Shengji HDPE liner, the non-failure operational time related to either abrasion or corrosion, between sucker rod and tubing increases by 400%. The HDPE/EXPE liner tubing reduces the energy consumption and increases the fatigue lifespan of sucker rod string. This solves abrasion & corrosion problems commonly experienced in the oilfield.

Shengji was the first Chinese company to introduce HDPE/EXPE liner tubing production line in 2003. To date, Shengji has produced over 8,000,000 m HDPE/EXPE liner tubing for more than 6,000 wells in both domestic market and abroad.

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.
