Materials for the petro-chemical industry

An Introduction

The world of Petro-Chemical engineering is unquestionably a most testing industry for engineering materials. Not only is there the severe corrosion threat from chemicals used in the refining of oil into petrol, there's also the fact that oil is often mined at sea - being brought up from below the sea bed - compounding the issues of corrosion by adding salt water into the mix. In addition to this, high temperatures are demanded, which must also be cooled to maintain machinery's lifespan and increase mechanical efficiency. 

 

Materials used in the Petro-Chemical Industry must be resistant to corrosion from saline solutions, aqeuous solutions and corrosive chemical attack as well as high temperatures, high pressures and the forces of drilling and tidal activity. As one might expect, the materials required are very specialised, but rest assured that Integ Metals have the capability of supplying all of your material leads, complete with mill certificates, if required. 

The materials and applications on this page are listed solely as a guide and do not reflect the limit of our supply, or the uses of said materials. If you have a specific application for which you need particular materials, please do not hesitate to contact us.

aluminium

Pros

+ Lightweight and low density - useful for drill pipe shafts used in marine               environments. 

Grade 5xxx Alloys have good resistance to corrosion from sea water

+ Good resistance to crude oi

+ High strength for large structures, whilst being light weight allows                         larger structures to be built, whilst requiring shallower support foundations

Cons

+ Excellent corrosion resistance to sea water and a wide range of acids and           alkali chemicals

Very high strength

+ Superior high temperature properties

+ Exceptionally long service life

Ability to contain high pressures

Resistance to creep allowing narrow bore pipes to be used under high                  pressure

Lightweight, making it very easy to transport, and can be coiled thereby               increasing shipping capacity.
