INQUIRY
  • PRODUCT DETAIL
  • Material

Slip on flanges (SO flanges) are slipped over the pipe and welded (usually both inside and outside) to provide strength and prevent leakage. Slip-on Flanges are at the low cost end of the scale, and do not require high accuracy when cutting the pipe to length. These SO Flanges can sometimes have a boss or hub, and can be made with a bore to suit either pipe or tube.

Titanium information group has 3 warehouses in Wenzhou, Wuxi and Hebei. As one of the piping solution providers, Titanium information group has been committed to providing one-stop solutions for projects in the fields of oil and gas, water, renewable energy and infrastructure. With years’ consistent dedication and innovation, our reliable, cost-effective and environment-friendly solutions have won clients’ wide recognition.

China Slip-On Flange manufacturer Titanium information group supplies Slip On Flanges, SO Flanges, Slip-On Flanges in forged steel, Stainless Steel, alloy steel, etc.
