Home / Products / Flanges / Slip-on Flanges

Our organization is engaged in offering a wide range of ANSI B 150 Class - Sorf Flanges fabricated in accordance with the international quality standards. The flanges are offered in full thickness C or with raised face removed as per the specifications of our clients. In addition the weight is based on data and is appreciated for accurate dimension and high performance.

Slip-on Flanges / SORF Flange

The flange is slipped over the pipe and then welded both inside and outside to provide sufficient Strength and prevent leakage. This flange is used in preference to weld necks by many users because of its lower cost and the fact that less accuracy is required when cutting pipe to length.

Sizes for Slip On Flanges

All Slip On Flanges are available available in sizes from 1/4” through to any size.

Wall Thickness for Slip On Flanges

Schedule 5s through to Schedule XXS and heavier.
