Slip On Flanges
Slip on flange are slipped over the pipe and welded (generally both inside and outside) to give quality and prevent spillage. Slip on Flanges are at the minimal effort end of the scale, and don't require high precision when slicing the pipe to length. These slip on can here and there have a manager or center point, and can be made with a drag to suit either pipe or tube.

Faqs
A slip on flange is a type of pipe flange that allows the pipe to slip inside the flange before welding. It is welded both inside and outside to provide strength.
They are mainly used in low-pressure, low-temperature applications such as water lines, cooling systems, and fire-fighting pipelines.
They are produced in carbon steel, stainless steel, alloy steel, and other special alloys depending on the application.
