FULL COUPLING / HALF COUPLING / REDUCING COUPLING / THREADED COUPLING THREDED UNION / SOCKET WELD UNION
At C-Way Engineering Exports, we specialize in manufacturing high-quality Couplings and Unions pipe fittings designed to meet the diverse needs of industries such as oil and gas, chemical processing, food, water treatment and more. Our couplings, available in full, half, reducing, and threaded variations, are engineered for permanent or semi-permanent connections in high-pressure systems. Similarly, our unions, including threaded, socket weld, and flanged types, ensure secure, detachable connections for systems requiring regular maintenance. Manufactured from premium materials like carbon steel (ASTM A105, EN P235GH), stainless steel (SS304, SS316), and alloy steel (F11, F22), our products comply with ASME, EN, and DIN standards. Whether for low-pressure applications or high-temperature environments, our couplings and unions are designed to deliver exceptional durability and efficiency. Each fitting undergoes stringent quality checks to meet ISO 9001:2015 and CE certification requirements, ensuring superior performance and reliability.
All pipe fittings with standard sizes and materials are readily available in stock for immediate delivery. "Looking for large diameter pipe fittings? Contact us today for Customized Pipe Fittings.
