The chemistry of alloy precipitation is an exact and ever-evolving science. For example, pipe fittings created for high level physical and chemical industries, such as petrochemical and oil refining plants, must be manufactured to a very high degree of resistance to physical stress and corrosion.

The alloys for our pipe flanges, fittings and fastenings are made from a base of either ferrite or austenite steel, which is combined with other elements to create a unique crystalline matrix. Depending on the elements used and their percentage content, the alloy will show superior strength, resistance to impact, low corrosion, and minimal distortion under pressure and heat resistivity. Pipe flanges used in specified locations, for example in deep submarine pipelines, will be expected to be highly specific for that environment.

The pipe fittings we stock at ChemiPetro are highly specific to the industries we deal with, which require extreme levels of corrosion resistance. For this reason our pipe flanges are made from superior austenite steel alloys, rather than ferrite alloys (which corrode easily). However, ferrite has double the strength of austenite, so when the two are combined you have the perfect material for industrial pipe flanges.

Our duplex and super duplex pipe flanges contain equal amounts of ferrite and austenite, as well as other elements besides nickel and chromium. This creates “super-alloys” that are highly resistant to pitting and crevice corrosion, have a low incidence of chloride stress induced cracking, extreme strength and weld stability.

This makes them highly suited to use in undersea pipelines, oil refineries, gas processing plants, pulp and paper plants and chemical factories. We at ChemiPetro stock a wide range of industrial pipe flanges and other fittings in duplex, super duplex, molybdenum, titanium and stainless steel alloys.
