    Heavy-Duty Dismantling Joint (Type C2F)

    1.Double-flanged power transmission and restraint joint designed for pump, valve, and equipment connections requiring secure thrust restraint and length adjustment.
    2.High-tensile Grade 8.8 tie rods (hot-dip galvanized or A4 stainless steel) prevent pipe pull-out under pressure thrust loads.
    3.Conical EPDM or NBR rubber gasket delivers uniform circumferential compression and zero-leak service across all pressure ratings.
    4.Quick-adjust design allows valve installation and removal without pipe cutting — create withdrawal clearance by retracting the movable sleeve.
    5.DN50–DN4000 (2″–160″) with PN10–PN40 / Class 150–300 pressure ratings and Ductile Iron or Carbon Steel body.
    6.WRAS-approved Fusion-Bonded Epoxy (FBE) coating (≥250μm) for potable water service and buried pipeline installation.
    7.Installed length adjustment range of ±15–25mm compensates for pipe misalignment, thermal expansion, and installation tolerance accumulation.
    8.Full restraint design transfers thrust loads directly to the tie rods and anchor flanges — no pipe shoulder reliance required.

    High-Strength Universal Flange Adaptor

    1.This versatile mechanical coupling directly connects plain-ended pipes to flanged valves, pumps, flow meters and fittings, eliminating welding, threading and special tooling entirely.
    2.Multi-material compatibility: compatible with ductile iron, PVC, steel, PE/HDPE and GRP as well as asbestos cement pipes — a single adaptor suits all piping systems.
    3.Fast installation using only standard wrenches for bolt-and-nut assembly; no hot work permits, welding teams or specialized equipment are needed.
    4.Fusion-bonded epoxy (FBE) coating (minimum thickness 250 μm) delivers superior corrosion resistance for buried and submerged applications, with a design service life exceeding 50 years.
    5.Built-in EPDM or NBR rubber gaskets form a full 360° circumferential seal. EPDM gaskets comply with NSF/ANSI 61 standards for potable water pipelines.
    6.Built-in tolerance absorption accommodates pipe misalignment, angular deflection of ±5°, and thermal expansion and contraction of pipelines.
    7.Sizes range from DN50 to DN2000 (2″–80″), with pressure ratings PN10–PN40 / Class 150–300; housings are available in ductile iron or cast steel.
    8.Perfect for emergency pipeline repairs, system retrofits and new installations where traditional flanged connections cannot be implemented.
