The flange adaptor (stub flange) is a heavy-duty connection fitting engineered to transition from a solvent-weld U-PVC pipeline to a bolted flange assembly. Manufactured via high-precision injection molding from unplasticized polyvinyl chloride, this adaptor provides a perfectly flat, uniform mating surface to ensure a leak-proof, compressed seal against metal flanges, gate valves, or industrial pumping equipment.

Within the agricultural sector, flange adaptors serve as the engineering standard for assembling high-capacity pumping stations and primary filtration manifolds. Thanks to the exceptional chemical inertness of the material, the joint remains completely immune to the corrosive effects of agrochemicals and liquid fertilizers, unlike traditional metallic alternatives. The optimized geometry of the fitting ensures even stress distribution during bolt torqueing, eliminating plastic deformation and guaranteeing long-term reliability at the most structurally loaded nodes of the irrigation network.

Application: Constructing a detachable, bolted flange connection in high-pressure piping systems
Type: Solvent-weld stub adaptor (requires a backing/loose flange for installation)
Operating pressure: Up to 16 bar (PN16)
Material: High-impact U-PVC
Maximum operating temperature: Up to +45°C
Color: Dark gray
Service life: Exceeds 50 years under standard operational conditions

Flange adaptors are widely utilized in manifold piping for large-scale water storage reservoirs, installing high-flow rate disc or screen filtration batteries, and coupling primary PVC mainlines to carbon steel or cast-iron gate valves. They are absolutely indispensable in large commercial greenhouse complexes and open-field systems where modular layout and rapid equipment dismantling are required for seasonal maintenance. Environmental Stability: Outstanding resistance to corrosion and UV radiation makes these adaptors an ideal choice for harsh open-field environments. Hydraulic Shock Resistance: The high mechanical strength of the product ensures stable performance even when subjected to severe hydraulic surges (water hammer) caused by starting high-power irrigation pumps.
