National Coupling Company, Inc. (NCC) is located in Stafford, Texas, southwest of downtown Houston. Founded in 1968, NCC began its business manufacturing commodity air coupling products for industrial applications. As oil and gas exploration accelerated in the 1970’s, NCC developed and introduced a new line of elastomer hydraulic couplings specifically designed for subsea blowout preventer (BOP) control system applications.
In the early 1980’s, subsea oil and gas production systems were being developed requiring high reliability subsea components including hydraulic couplings. In response to this emerging need, NCC developed a metal-to-metal seal hydraulic coupling and was awarded its first patent in 1987. This design was the industry’s first radial metal-to-metal seal design that established a truly redundant (dissimilar) seal system for the highest reliability in deepwater and high pressure subsea applications. Today, with over 40 years of coupling design and manufacturing experience and over 300 U.S. and Foreign patents granted, NCC is still producing hydraulic couplings for the most critical applications including extreme high pressure/high temperature designs up to 17,500 psi and 350º F. NCC continues to be the industry leader in subsea hydraulic coupling technology with 11 design series and over 2800 different hydraulic coupling designs for a broad range of applications, primarily for subsea drilling and production systems.
As part of NCC’s diversification strategy, the Company introduced a new and revolutionary Chemical Injection System design for subsea applications in 2006. The system utilizes positive displacement metering to provide precise control and verification of chemical injection rates without the use of flow meters. Continuing the diversification strategy, NCC introduced a new line of Specialty Valve products that includes a subsea Chemical Injection Back Pressure Valve designed for subsea BOP control systems and other special purpose directional control valves. Beginning in 2007 NCC began performing specialized welding operations internally to provide customers with complete hydraulic coupling-to-tubing weldment assemblies with full NDE and pressure testing documentation.
NCC continues to be committed to providing the industry with the highest quality products and services, technical innovation, state-of-the-art manufacturing capabilities, on-time delivery and an unsurpassed level of customer service. NCC is proud to be a reliable Solutions Provider to the oil and gas industry today and is poised for the challenges and opportunities of tomorrow. |
