〖Rational design〗Based on the load and torque borne by the pipeline, the corresponding wall thickness and length were determined, and the installation speed was accelerated by 60%. Eliminating welding - saving labor costs compared to traditional flange methods
〖90° Precise Angle Design〗 Provides smooth directional changes in piping systems, reducing flow resistance and minimizing turbulence
〖UL/FM-Certified Fire Safety〗 Certified by UL (Underwriters Laboratories) and FM (Factory Mutual), ensuring compliance with stringent safety and quality standards for fire protection and industrial applications
〖Ductile Iron Durability〗 Corrosion resistance – ideal for outdoor pump rooms and harsh environments
〖Lifetime Cost Savings〗 45% lower maintenance costs than welded joints over 25+ year service life Includes 5-year manufacturer warranty against material defects
