Product Advantages:
Angular, lateral & axial displacement compensation far beyond standard couplings.
Isolates vibration and water hammer to protect pumps, valves and piping.
EPDM/NBR/Neoprene body resists acid, alkali, seawater and steam.
Absorbs pipe misalignment, cutting labor and field modification costs.
CHANGHONGSHENG Discover high-quality flexible joints for a wide range of industrial piping applications. Designed for reliable sealing, vibration absorption, pressure resistance, and easy installation, they help improve system performance and durability.
Body & Flanges: Ductile Iron (GGG50/ GGG60), epoxy-coated for corrosion resistance
Sealing Sleeve: EPDM rubber (NBR optional for oil media)
Bolts, Nuts & Washers: Carbon steel with hot-dip galvanizing or Dacromet coating
Working Pressure: PN10/ PN16 (higher ratings on request)
Size Range: DN50 - DN300 (custom sizes available)
Color: Standard blue (RAL 5015) / Red, customizable
Wide Tolerance Range —Stepped design accommodates multiple pipe OD standards (ISO, Dl, PVC, PE, AC, Steel), reducing the
need for different fittings on site.
Leak Proof Sealing —Integrated EPDM sleeve delivers reliable water -tight performance under pressure fluctuation and ground
movement.
Angular & Axial Deflection—Allows up to ±3-5° angular misalignment and axial expansion/contraction during installation and
operation.
Corrosion-Resistant Coating —Fusion-bonded epoxy (FBE) or anti-rust paint coating extends service life in buried or humid
environments.
Easy Installation —Bolted connection requires no welding or special tools, suitable for both new projects and retrofit
applications.
Reusable & Maintenance-Friendly —Bolts can be released for re-positioning, pipe replacement, or future maintenance
