In the industries that we at ChemiPetro supply, it’s important the products are of a very high quality, able to withstand pressure, and are chemical resistant. This is why we always recommend duplex and super duplex pipe flanges and fittings as being the most suitable.

Flanges are pipe fittings used to assemble pipes together quickly and efficiently. There are many different flange standards, depending on what the product is to be used for.

The pipe fittings we supply at Chemipetro have specific dimensions unique to the petrochemical, gas and oil industries. They are standardised to allow easy and inter-changeability between products. British pipe flanges are classified to BS standards, e.g. BS10. European pipe fittings, meanwhile, are classified to PN/DIN standards, and American to ASA/ANSI standards.

It’s important to realise you can’t match one standard with another. So you can’t put a BS flange on an ANSI pipe, for example. However, there are a growing number of pipe fittings showing a BS/ANSI configuration; this means they are compatible with both. Most of our products show ANSI standards. The US leads the world in the manufacture of high spec pipe fittings – ideal for the industries that we at ChemiPetro supply.

Super duplex stainless steel pipe fittings are made to very high specifications and are heat, pressure and chemical resistant. Although Duplex steel is corrosion and rust resistant, super duplex has higher levels of Molybdenum and Chromium, which increase its resistant properties.

Pipe flanges are potentially the weakest point in a pipe system. However, pipe flanges can be the system’s greatest strength if the right products are used.
