Connertt Piping Compensatory Couplings are manufactured in strict accordance with international industrial standards, adapted to PN series flange connection dimensions (ISO 7005-1), and widely applicable to multi-medium pipeline transportation scenarios such as seawater, fresh water, cold and hot water, drinking water, crude oil, fuel oil, gas and steam ≤205℃. The product covers six categories: sleeve type, limited type, force transmission type, large flexibility type, spherical type and pressure balance type. All models have passed the 1.5 times nominal pressure strength test and 1.25 times nominal pressure sealing test, with no leakage and no plastic deformation under pressure for 5 minutes. It accurately absorbs the axial and angular displacement of the pipeline, balances the internal pressure thrust, and effectively solves the connection problems caused by pipeline installation errors, thermal expansion and contraction and vibration. High-quality base materials of European/American standards are carefully selected for materials: carbon structural steel complies with EN 10025/ASTM A36, stainless steel adopts EN 1.4404/ASTM A316 (special for seawater/steam medium) and EN 1.4301/ASTM A304, fasteners match ISO 898/ASTM F593 standards, and sealing rubber is adapted to EN ISO 60721/ASTM D2000 series rubber compounds according to the medium. Surface protection adopts hot-dip galvanizing (EN ISO 1461), nickel-phosphorus coating (ISO 4520) and other processes, with corrosion resistance and wear resistance, suitable for harsh industrial environments. From shipbuilding heavy industry, chemical refining to municipal water supply and drainage, gas engineering, Connertt provides safe, stable and long-term connection and compensation solutions for various pipeline systems with standardized design and high-precision manufacturing. #PipingCompensatoryCoupling #ISO7005Flange #MultimediumCompensatoryCoupling #IndustrialgradeCompensatoryCoupling #AxialAngularDisplacementCompensation #InternalPressureThrust Balance #EN10025CarbonSteel #EN1.4404StainlessSteel #ISO1461HotdipGalvanizing #PipelineInstallationErrorCompensation #DismantingJoint
