Multi Metal Corporation is a leading manufacturer, exporter and supplier of stainless steel bends, carbon steel bends, and alloy steel bends in a complete range of radius and diameters. Steel pipe bends can be manufactured from a wide range of pipe materials – including low and high yield carbon steels, alloy steels, stainless steels, Cr-Ni alloys and titanium. We specialise in the manufacture of large and small size stainless steel bends and piggable bends in grades Duplex, 310S, 304L, 316L, 317L, 347, 321, 904L.

Slip-on pipe flange usually slips over the pipe. Slip-on pipe flanges are typically made with an inside diameter of the pipe flange slightly larger than the outside diameter of the pipe. This allows the slip-on flange to slip over the pipe. Slip-on pipe flanges are welded (usually both inside and outside) to provide strength and prevent leakage. Slip-on pipe flanges can sometimes also have a boss/ring or hub, and can be made with a bore to suit either pipe or tube. Ring pipe flanges and hub pipe flanges are both considered slip-on pipe flanges because they both slip over the pipe.

Slip-on flanges are generally preferred by users over weld neck flanges, as they are a cheaper option than weld neck flange and the fact that less accuracy is required when cutting pipe to length.

Slip-on flanges are available with raised, flat or RTJ faces, and are also available in orifice configurations.
