There has always been a need, within the PGO (petrochemical, gas and oil) industries, for alloys that can be precision formed and welded, guaranteed to be of extreme longevity, of a guaranteed composition that will produce continuous standards of use within set environmental ranges and are affordable.

The desired qualities of PGO pipe fittings are affordability, coupled with a high degree of resistance to their environment. This means minimum pitting, cracking and rusting coupled with high-tensile strength. Such products must be precision engineered to a high degree of accuracy, and guaranteed to maintain their qualities over a minimum period of time – the longer, the better. This has led to the evolution of many superior alloys over the years.

The PGO industries have very specific needs, which vary depending on the application. Evidently, a budget must be adhered to, but it is pointless fitting out a new chemical plant with pipe flanges that will show weld decay after just a few months, and need expensive replacement – and possibly closure of the plant while repairs are done.

Gas pipelines, oil refineries etc are similarly maintained to strict industry guidelines. It is essential, for example, that the flanges and welds of undersea refinery pipelines have a guaranteed lifespan and will not fail prematurely. For environmental, commercial and health and safety reasons, pipe flanges of PGO plants and pipelines both above and below ground must be manufactured to exacting and precise standards.

At ChemiPetro, we stock pipe fittings in alloys ranging from standard SAE 304 to super duplex and titanium grades. We always endeavour to give our customers the highest quality, at the most competitive prices.
