High Pressure Threaded Union

A threaded union is a crucial detachable pipe connector used to join two straight pipe sections in fluid transmission systems. Different from fixed pipe couplings, it allows free assembly and disassembly without cutting or damaging the pipeline. This fitting provides rigid connection and zero-leakage sealing for industrial piping, ensuring stable fluid transportation for liquid, gas and oil mediums.

All threaded unions are integrally forged instead of casting. The whole body is formed by one-time forging to achieve dense internal structure, no sand holes, no porosity and no cracks. Adopts advanced CNC precision thread turning technology. Thread teeth are uniform, smooth and highly matched with standard pipe threads. The thread surface is finely processed to avoid burrs, ensuring tight screwing and consistent installation accuracy.

Superior pressure bearing capacity. The forged integrated structure greatly improves structural strength, enabling the fitting to work stably under medium and high-pressure working conditions, resisting pipeline impact and pressure fluctuation. Excellent sealing property. Matched with standard sealing surface design, it achieves full-face fitting, effectively preventing medium leakage under dynamic and static working conditions. Great durability. The surface is treated with anti-rust and anti-corrosion process, resisting oxidation, acid and alkali corrosion, adapting to harsh industrial environments. Flexible and practical. The union structure allows fast disassembly and repeated use, which greatly facilitates pipeline inspection, cleaning, repair and replacement.

Available in multiple industrial standard materials, including carbon steel, stainless steel 304 and stainless steel 316. Carbon steel is suitable for conventional industrial pipelines with strong pressure resistance. 304 stainless steel provides excellent rust-proof performance for water and general corrosive medium. 316 stainless steel offers higher acid and alkali resistance, ideal for chemical and marine industrial piping.

Manufactured in strict accordance with international pipe thread standards. All thread specifications are fully compliant with common industrial standards, with high interchangeability. Each product is strictly inspected for dimension accuracy, thread tolerance and pressure resistance to ensure full compatibility with standard pipeline systems.

Widely applicable in petroleum, natural gas, chemical engineering, power plant equipment, mechanical manufacturing, water supply and drainage, fire protection systems and industrial fluid delivery pipelines. It is the preferred connecting fitting for equipment pipelines that require frequent disassembly, daily maintenance and regular overhaul.

Threaded union fittings solve the maintenance difficulty of fixed pipe connections. With reliable sealing, stable performance and long service life, they reduce pipeline failure rate, lower later maintenance costs and improve the overall safety and stability of industrial piping systems.
