Slip-On Flanges are one of the most widely used flange types in modern piping systems due to their ease of installation, cost-effectiveness, and reliable performance. At Neonox Overseas, we manufacture and supply a comprehensive range of Slip-On Flanges that cater to various industries including oil & gas, petrochemical, power generation, water treatment, pharmaceuticals, shipbuilding, and offshore applications. Designed with a low-profile hub, these flanges are simply slipped over the pipe and then welded both inside and outside, providing excellent structural strength while ensuring leak-proof connections.
The key advantage of Slip-On Flanges lies in their ability to accommodate pipes of different thicknesses, making them versatile across a wide spectrum of operating conditions. Their smooth bore alignment reduces pressure drop and minimizes turbulence, thereby ensuring efficient fluid or gas flow. These flanges are highly economical compared to other flange types, making them ideal for low-pressure, moderate-temperature pipelines where welding integrity is essential.
At Neonox Overseas, we manufacture Slip-On Flanges in a variety of materials to meet diverse project requirements. Our range includes Stainless Steel Slip-On Flanges (304, 304L, 316, 316L, 310, 321, 347, etc.), Duplex and Super Duplex Steel Slip-On Flanges (2205, 2507), Nickel Alloy Slip-On Flanges (Inconel, Monel, Hastelloy, Nickel 200/201), Titanium Slip-On Flanges, Copper Nickel Slip-On Flanges (Cu-Ni 70/30, Cu-Ni 90/10), Alloy 20 Slip-On Flanges, SMO 254 Slip-On Flanges, Carbon Steel Slip-On Flanges (ASTM A105, A350 LF2, IS 2062), and Alloy Steel Slip-On Flanges (A182 F11, F22, F5, F9, F91). Each flange is engineered to comply with international standards such as ASME, ASTM, ANSI, DIN, BS, EN, and ISO, ensuring global acceptance and reliability.
We provide Slip-On Flanges in sizes ranging from ½” to 48” (DN 15 to DN 1200) with pressure ratings up to 2500#. These flanges are available in raised face (RF), flat face (FF), and ring type joint (RTJ) designs to meet specific industry needs.
