Product Details

Our products are tested by Tubular Inspection Center of China National Petroleum Corporation, and each performance index meets America ASTM A269, and related industry standards, partial quality index even exceeds the international level. Our products are well accepted by domestic oifield such as Shengli Oilfield, Daqing Oilfield and etc. Our products are mainly applied in petroleum industry, chemical industry, shipbuilding, natural gas, etc.


The company has passed certification of CCS, GL, DNV, ABS and etc. High quality and good service make our products exported to many countries.

Seamless control lines are used in SCSSV, Chemical Injection, and Advanced Well Completions. Seamless tubes provide another tubing solution for our customer's complex well designs. The most common uses for Seamless line tend to be shorter length applications whereby no orbital welds are required.


Welded Control Lines are the preferred construction for lines being used in downhole oil and gas applications. Our welded control lines are used in SCSSV, Chemical Injection, Advanced Well Completions, and Gauge Applications.
