Couplings

Couplings are connecting elements designed for the hermetic joining of two straight pipe sections of the same diameter. They provide a strong connection without changing the flow direction, featuring easy installation and a compact design. Couplings ensure reliable and uninterrupted pipeline operation even under high pressure and elevated temperatures. They are made from various materials resistant to aggressive environments, making them suitable for use in gas supply systems and the petrochemical industry.

Connecting and reducing couplings for pipelines at competitive prices. A wide range of ASME couplings: threaded, combined, union, and couplings for oil and gas production pipelines. Delivery to the destination point. Couplings are designed for leak-tight connection of pipes in industrial pipeline systems. They ensure reliable fixation of pipeline sections while maintaining system integrity under high loads. Manufacturing materials include carbon and low-alloy steels, alloy grades with increased strength and heat resistance, as well as stainless austenitic, duplex, and super duplex steels. The coupling design compensates for axial displacement and stabilizes pipeline operation under temperature fluctuations and exposure to aggressive environments. The products comply with international standards such as ASME, BS, EN, and ISO, and are widely used in the oil and gas, petrochemical, chemical, and power generation industries.
