Import Api Tubing — Buy in wholesale FOB from Supplier in China

Dynoland Industrial Supply Co., Ltd. offers API tubing in standard sizes of 1.9", 2 3/8", 2 7/8", 3 1/2", 4", and 4 1/2" outer diameters, with grades including J55, N80, L80, C90, T95, P110, and Q125. The tubing is manufactured using ERW, hot rolled seamless, or upset methods, with a 3 step forging mold and full body normalization applied after upset to ensure material integrity. Specialized Vacuum Insulated Tubing (VIT) is available for steam injection wells, designed to lower the viscosity of heavy crude oil.

The tubing features various API connections, including Non Upset (NUE), External Upset (EUE), and Round Thread (8RD and 10RD), as well as premium connections like HSM, TP CQ, and RJS, which are compatible with VAM and HSC standards. Additional technical modifications include a resilient seal (SR 13) with an extra Teflon ring, special clearance for extra clearance applications, and a 20° bevel for specific joining requirements. Internal coatings such as FBE, tungsten nickel alloy electroplating, and titanium zirconium alloy powder are available for enhanced corrosion resistance.

This tubing is primarily used in oil and gas extraction, particularly in wells requiring high pressure and temperature resistance. Buyers in the energy sector source these products for their durability and compliance with API standards, with length ranges available in Range 1, 2, and 3. The tubing is bundled with steel belts and end protectors for safe transportation, and options like vacuum nitriding coating, vacuum insulated tubing, and HDPE liners are offered for specialized applications.
