Carbon steel, stainless steel, and alloy steel slip-on flanges are available in a wide range of sizes, from 1/2" to 48" or larger. These flanges are designed for various pressure ratings, ranging from 150LB to 2500LB, making them suitable for a variety of industrial applications. The flanges come in different types such as Slip-On, Welding Neck, Blind, Lap-Joint, Spectacle, Socket-Welding, Threaded, Ring Joint, Orifice, Tongue & Groove, and more.
They are manufactured according to international standards including ANSI B16.5, API 605, MSS SP 44, API 6A, JIS B2220, DIN 2573/2576/2544/2545, DIN 2527, DIN 2631/2632/2633/2634/2635, UNI 2276/2277/2278/2280/2281/2282/2283/2284, UNI 2253, UNI 2229, UNI 6100-67, AS 4087, ISO 7005, and EN 1092.
Materials used include carbon steel (A105), stainless steel (F304, F304L, F316, F316L), and alloy steel (F52, F60, F65, F70, F11, F22, F51). The flanges are forged using high-quality materials and are available with different sealing surfaces such as RF (Raised Face), FF (Flat Face), and RTJ (Ring Type Joint).
All products are produced under strict quality control and meet the requirements of major international standards like API, ANSI, AWWA, JIS, BS, and DIN. Many of our manufacturers hold ISO 9001, API 6D, TUV, and CE certifications, ensuring consistent product quality. We also provide mill test certificates (EN 10204-3.1B) for all products supplied.
Our product range includes not only flanges but also a wide variety of pipeline components such as ball valves, gate valves, globe valves, check valves, butterfly valves, plug valves, safety relief valves, diaphragm valves, steam traps, knife gate valves, strainers, quick couplings, pipe fittings, bolts, nuts, gaskets, steel plates, tubing, casing, line pipes, and more. These products are widely used in industries such as oil and gas, hydraulics, refining, chemicals, petrochemicals, pharmaceuticals, food processing, fire safety systems, marine systems, and power generation.
