Slip-on flanges are slid over the pipe and fillet welded, offering easy alignment and installation for moderate-pressure systems.




The Slip-on Flange is a popular and cost-effective pipe flange solution widely used in various industrial piping systems. Designed to slide over the end of the pipe and be fillet welded both on the inside and outside, the Slip-on Flange ensures strong, leak-proof connections while being easier to align than other welding flanges. It is ideal for low-pressure and non-critical applications where frequent dismantling is not required.
As one of the professional Slip-on flange suppliers, we manufacture Slip-on Flanges using high-quality stainless steel and nickel alloy materials to provide excellent corrosion resistance, durability, and long-term performance in harsh environments. Whether installed in chemical processing plants, marine systems, oil and gas refineries, or power generation facilities, our stainless steel slip-on flanges and nickel alloy slip-on flanges meet global standards including ASME, ANSI, and DIN.
The Slip-on Flange is valued for its simple structure, easy installation, and lower fabrication cost. It is especially suitable for systems with moderate pressure and temperature requirements.
