Sleeve couplings without welded joints (grooved) ensure reliable fastening between pipes, withstanding high pressure. Couplings enable quick installation or dismantling of pipes. This is advantageous in cases where welding cannot be used (fire and explosion hazardous facilities) or urgent repairs are required. Installation time is reduced by up to 55% when using a weldless fitting method of fastening.
Couplings (fittings) have a high degree of reliability and durability.
