The channel connecting the ground to the reservoir withstands high-pressure oil and gas erosion and corrosion, ensuring efficient oil and gas production.
Product Specifications: 1.050″ to 4-1/2″
Steel grades: H40, J55, K55, L80, R95, N80 1/Q, C90, T95, P110
We provide users with oil pipes meeting all API SPEC 5CT standard steel grades and thread types, including H40, J55, K55, L80, R95, N80 1/Q, C90, T95, and P110 steel grades. The product dimensions cover all external diameters, wall thickness specifications, and thread types specified in the API SPEC 5CT standard.
Shape: 60° dome-shaped conical thread with circular base, taper ratio 1:16
Pitch: 8 teeth/in (3.175 mm), 10 teeth/in (2.54 mm)
Structure: The tube end is not thickened; connected by a coupling clamp without a shoulder
Sealing: tooth surface + thread grease seal with non-metallic auxiliary sealing
Features: affordable, easy to process, and quick to fasten
Applicable to: shallow wells, conventional vertical wells, and low-pressure oil and gas wells
The end of the tube is enlarged and thickened, resulting in longer thread engagement and enhanced load-bearing capacity
The tensile, torsional, and fatigue resistance far exceed those of NUE
Higher sealing reliability with reduced risk of disengagement or leakage
Applicable to: medium-deep wells, inclined wells, wells with reciprocating pump pumping, and wells under alternating loads
Manufactured to standard specifications, globally interchangeable, easy to procure and maintain, with ample spare parts available.
The technology is mature, the cost is low, and the installation and removal of fasteners are simple.
The curved tooth base ensures stress dispersion, resistance to minor impacts, and effective stain retention with anti-adhesion properties.
Strictly adheres to the API 5CT standard, ensuring stable and reliable quality.
It offers a wide range of strength grades, from H40 to P110, precisely meeting the requirements of various well depths and operating conditions.
Ensure structural stability of the wellbore, enhance oil and gas extraction efficiency, and reduce operational risks.
