siddhivinayak Steel is a specialised manufacturer of high quality ASME/ANSI/DIN standard slip-on flanges in India. We offer immediate delivery programs for standard size of carbon steel slip-on flanges and stainless steel slip-on flanges. Slip-on flanges manufactured in special stainless steel grades, nickel alloy and alloy steel can be supplied with just in time programs.
Slip-on pipe flange usually slips over the pipe. Slip-on pipe flanges are typically made with an inside 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.
We offer slip-on pipe flanges manufactured at our facility to companies in various industries including shipbuilding, power generation, petrochemical plants, oil refineries, waste water treatment plants, paper mills, pharmaceutical plants and turnkey projects among others.
