Overview
Grooved Flanges, including Split Flanges, are specialized pipeline components designed to connect pipes and valves securely and efficiently. They provide a reliable mechanical connection with faster installation times and reduced space requirements compared to traditional threaded or butt-welded flanges. Split flanges allow easy assembly and disassembly without rotating the pipe, making them ideal for maintenance and retrofit projects.
Product Description
A Grooved Flange features a raised edge with bolt holes that align with matching flanges, providing a secure bolted connection. A gasket is placed between the flange faces to ensure a leak-resistant seal. Split Flanges, or two-piece flanges, allow installation over an existing pipeline without disconnecting the pipe, which is particularly useful in tight spaces or retrofit scenarios. Available in various pressure ratings, typically PN16 and PN25, these flanges are suitable for a wide range of industrial, commercial, and fire protection piping systems.

| 1.Take out the Rigid &Flexible Coupling Clean the gasket sealing surface within 16mm of the hole and visually inspect the sealing surface for defects that may prevent proper sealing of the gasket.Don't drill the hole on weld line. | 2.Split the Rigid &Flexible Coupling If any burrs or slug exists at the pipe hole,please remove them before assembly,to protect the gasket and avoid leakage. | 3.Pipe preparation Insert the gasket into outlet housing making sure the tab in the gasket line up with the tab recesses in the housing.Align outlet housing over the pipe hole making sure that the locating collar is in the pipe hole. | 4.Lubricate gasket Align the strap around the pipe,inser the bolts and tighten the nuts finger tight. | |||||
