Senrui is a professional manufacturer and supplier of high-quality Slip On Flange (SO Flange) products for industrial piping systems worldwide. Our flanges are available in stainless steel flange, carbon steel flange, and alloy steel materials, designed to provide secure sealing performance, easy installation, and long-lasting durability in demanding environments.
A slip on flange is widely used for low to medium pressure applications due to its simple installation and cost-effective welding design. The pipe is inserted into the flange and welded both inside and outside, ensuring stable connection and reliable operation in industrial pipeline systems.
With advanced manufacturing equipment and strict quality inspection, Senrui provides precision-machined flanges that meet international standards and project requirements.
Compared with some other flange types, the slip on flange is easier to align and weld, helping reduce installation time and labor costs.
