DIN Flanges Norms

All the Raw Materials received by our company are subject to chemical and physical test and weighed immediately on receipt only thereafter they are taken in the stock.

The Welding neck flanges is normally referred to as the high hub flange.

Welding Neck Flanges

A weld neck flange (also known as a high-hub flange and tapered hub flange) is a type of flange.

Threaded Flanges

Threaded flanges are widely demanded as pipe flanges i.e called as threaded pipe flanges used in different industrial applications.

Slip-on flange

Slip-On flanges or SO flanges are commonly lower in price than weld-neck flanges, and to this effect are a popular choice for our customers.

Blind Flanges

The blind flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes.

Applications Of DIN Flanges

In many applications, engineers need to find a way to close off a chamber or cylinder in a very secure fashion, usually because the substance inside must differ from the substance outside in composition or pressure.

DIN Flanges used in Chemical and petrochemical processing
DIN Flanges used in electronics
DIN Flanges used in processing equipment for maintaining product purity in handling foods, synthetic fibers
DIN Flanges used in marine and offshore engineering

Characteristics of DIN Flanges
