Although "inorganic fine chemicals" sound fairly innocuous, the range of processing conditions include extremely aggressive and hot mixtures of chemicals such as sulphuric, hydrochloric and nitric acids, ammonia, hydrogen peroxide and caustic soda.
The company traditionally used lined tanks including rubber lined steel, fluoroplastic lined steel and celmar, materials which in the arduous conditions experienced were prone to sudden failure.
This led to a search for new materials.
The Chem Resist development of a unique, patented spirally wound method of manufacturing one-piece homogeneous thermoplastic cylinders enables the design and manufacture of chemical tanks, vessels and equipment that could not previously be considered in "straight thermoplastic".
As a result a 12m3 HDPE vessel with a solid homogeneous wall thickness of 100mm was manufactured and installed.
Since the initial installation the company has replaced several of its traditional lined vessels and has installed further vessels on its "new" projects.
Chem Resist have the ability in the UK to manufacture the largest spiral wound plastic tanks in the world with volumes over 100m3.
And what's more, Chem Resist have over 40 years of experience in the use thermoplastic tanks in aggressive chemical applications.
