Chemical Processing

Chemical Processing

"In these extreme environments using the right materials and sealing products is not simply a requirement but an obligation. Seals and materials need to last longer, have higher levels of purity, and meet the increasingly stringent legislation"

Developing High Integrity solutions for Chemical Processing where the long term risks to personnel and the environment can be catastrophic requires meticulousness attention to detail, a thorough understanding of the working environment and a commitment to deliver the highest standards & manufacture throughout the supply chain.

The increasing complexity and continual drive for higher operating standards within the Chemical Processing market is a significant challenge for any supplier. Hazardous or unstable chemical compounds can destroy unsuitable sealing solutions, the consequence of which can be catastrophic. Delivering solutions that work requires an understanding not only of the anticipated conditions but also of the failure risks within the operation. If conditions change marginally the solution needs to accommodate the change and survive within parameters that allow the operators to de-risk the situation.

The toxic and corrosive nature of many of the Chemical processed not only demands high performing innovative solutions but sealing materials of the highest purity with full traceability and product testing throughout the supply chain and manufacturing process. MacLellan`s High Integrity Sealing materials provide an unmatched level of safety and reassurance, coupled with a consummate attention to quality and service.

In these extreme environments using the right materials and sealing products is not simply a requirement but an obligation. Seals and materials need to last longer, have higher levels of purity, and meet the increasingly stringent legislation associated with the hazardous activity such as :-

BPD/R – Biological Products Directive/Regulation

COSHH – Control of Substances Hazardous to Health

DSEAR – The Dangerous Substances & Explosive Atmospheres Regulations
