2 [4] LNGS Specifications SPIITIONS: NSI Pipe langes and langed ittings (merican) S langes for Pipes, Valves and ittings (ustralian) S ircular langes for Pipe, Valves and ittings (PN designated) - (now S N1092) (uropean) S Metallic langes for Waterworks Purposes (ustralian) S10 - Specification for langes and bolting for Pipes, Valves and ittings (ritish) **S2129 is a replica of S10 but is stated in mm rather than inches. In some sizes bolt holes are slightly larger to give better clearance PPLITION: Water Supply, Oil, Gas, Petrochemical, Irrigation, ire Services, General Industry, onstruction. MRKING: ll langes when possible will display a heat number, size, table, grade and dimensional standard PLT STL LNGS: Plate flanges are mainly used for light duty, lower pressure or non-critical applications, commonly referring to S2129, S10 or S4087 standards. The manufacturing method involves cutting and machining from plate steel ORG STL LNGS: orged Steel flanges are commonly used and specified in the Oil, Gas, Petrochemical and mining sectors, where pressure, temperature and safety considerations often specify the NSI 16.5, SM or S4504 standards.
