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.

· BS 3293 Class 150 WN Flange

· BS 3293 Class 300 WN Flange

· BS 3293 Class 600 WN Flange

· DIN 2631 PN 6 Flange

· DIN 2632 PN 10 Flange

· DIN 2633 PN 16 Flange

· DIN 2634 PN 25 Flange

· DIN 2635 PN40 Flange

Threaded Flanges

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

· DIN 2565 PN6 Flange

· DIN 2566 PN10 Flange

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.

· BS 3293 Class 150 SO Flange

· BS 3293 Class 300 SO Flange

· BS 3293 Class 600 SO Flange

· DIN 86029 PN 10 Flange

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.

· DIN 2527 PN10 Flange

· DIN 2527 PN16 Flange

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

DIN Flanges production and processing of finished solution treatment must be enclosed , so that product performance is optimal.

· DIN Flanges is highly resistant to various reducing chemicals

· DIN Flanges is excellent resistance to caustic alkalies

· DIN Flanges is high electrical conductivity

· DIN Flanges is excellent corrosion resistance to distilled and natural waters

· DIN Flanges is resistance to neutral and alkaline salt solutions
