Tubing & Casing Coupling
Coupling is the joining of two short length pipes by the means of male and female threads.
All types of couplings have internal threads which are known as female thread forms. These thread forms are usually machined so that they can be coupled with the external threads on pipes known as male thread forms. Couplings are strictly designed as per API specifications.
There are two types of tubing couplings widely used in the pipeline coupling manufacturing industries namely:
Non-upset Thread Tubing Coupling
External-upset Thread Tubing Coupling
Oil Pipes

Fast delivery, high quality, and cost-saving for customers. Our vision: To build an international petroleum pipeline equipment enterprise with integrity and innovation. We welcome leaders and friends from all walks of life to visit and explore cooperation opportunities.
1. Since 2008, with a registered capital of 11.18 million yuan and an 8,000 square meter workshop, the annual foreign trade turnover is 20 million yuan.
2. Holding the right to import and export, ISO9001 quality system certification, API 5CT certification from the American Petroleum Institute, and several national patents.
3. The production workshop is equipped with high-precision CNC lathes, thread rolling machines, hydraulic presses, and a complete set of inspection tools.
4. Products include J55, K55, N801/Q, L80, P110 oil and casing pipes, couplings, short connections, and transition joints.
5. We have a large inventory of high corrosion-resistant oil and casing pipes such as 80S, 90S, 110S, L801Cr/3Cr/13Cr, with about 2,000 tons in stock throughout the year.
6. We undertake special sealing thread processing and copper plating services for oil well pipes and petroleum accessories, including straight connection, wedge, double-step, and variable-pitch threads, with tens of thousands of special thread components produced annually.
Oil casings and oil pipes are critical components in oil and gas extraction, while the design of short joints, fittings, quick connectors, and integral connectors further enhances the connection efficiency and reliability of the pipes. TP110S oil pipe is a high-strength pipe suitable for various complex oil and gas extraction environments. The design of various fittings, quick connectors, and integral connectors improves the connection efficiency and reliability of the pipes. The quick connector design allows for easier connections, reducing installation time and labor intensity. The integral connector, through its integrated design, enhances the connection strength and sealing performance of the pipes.
The couplings produced by our company are good at stable quality which the technical parameters are completely complied with the requirements of API5CT and API5B latest standards. Meanwhile, the company has equipped with more than 30 sets CNC threading machines, is able to produce variety of steel grade couplings include STC, LTC, BTC and NU, EU threading couplings. Please visite our website: www.richsen.cn
The size for Tubing couplings are ranged from 2-3/8'' to 4-1/2'', as well as 4-1/2'' to 20'' for Casing Couplings. The company can produce all kinds of couplings over 1 million pieces annually.
