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.
