Welwin Pipes & Fittings

SLIP ON FLANGES

is a dynamic group, which was established over a decade ago to cater to growing demands of Slip On Flanges standards in ASME / ANSI B16.5 Flanges,ASME/ANSI B16.47 etc in all materials like Stainless Steel , Carbon Steel & High Nickel Alloys.

Slip On Flange is slightly larger than the outer diameter of the pipe it is to be used with. The pipe is slipped into the Flange prior to welding both inside and outside. High quality Slip on Flanges are ideal for lower pressure applications.

We Manufacture, Export and Supply Flanges which meets with national and international quality standards and producing base which owns equipments conforming to international technical level and is well equipped with a whole set of advanced plasma refining equipments.

We export our high quality Slip On flanges to Kuwait, Egypt and Qatar.
