ASME B16.48 Spades and Ring Spacer Manufacturers in India

The spacer ring dimensions consists of various other parameters like outside and inside diameter, centre to end, thickness, handle width and many more. These are known for excellent performance; corrosion resistance is good and the durability is good. Spacer ring for raised face flange has a welded handle which is in different form. Spacer ring for socket weld provide pre-measured 1/16 in minimum gap for socket welding contractions. The specifications of this materials consist of various sections like carbon steel spacer ring, brass ring spacer flange, Inconel ring spacer flange and lot more.

Spacer Ring

The spacer ring for flat face flange is thus widely used in many other industrial sectors. These are available in various sizes and also can be easily assembled or dissembled. Carbon steel spacer ring material is used for this flange as this is round shaped ring and the pressure used is 150-200 lbs. Pipe flange spacer ring is thus manufactured by thousands of steel companies but Regal Sales Corporation is the best as we are ISO certified and various steel products are available. Stainless steel spacer ring is thus available in stock and we also supply it to many other countries.

What do you mean by Spacer Ring ASME B16.48 ?


Spacer Ring are installed between stern tube and the AFT seal housing. Spacer ring flange is also known as spade flanges. These are used in installation of piping system and are available in filler flanges and ring spacers. It is usually designed from a single piece of metal that is cut to match the pipe size, these are fitted between the two pipe flanges and requires additional gasket when installed. Also, in oil and chemical process this is used.
