D u r a l i n eThe World's Finest Fire Hose

Topic: Chemical ResistanceToday's fire hoses are increasingly used in locations where aggressive chemical are present. BS6391 Type 3 or covered hoses are required to demonstrate chemical resistance. This is substantiated by the water pick-up test in BS6391.

Why is it important?

Synthetic textiles used in the reinforcement of covered fire hose are prone to attack by even weak acids or alkalis. The cover on Type 3 hoses are pin pricked during manufacture to allow volatile gases to escape during vulcanisation. Unless these holes are plugged with latex after manufacture then a reduction in burst strength can result if a hose is exposed to chemicals.

How does Duraline perform?

Duraline has totally sealed pin holes which prevent the ingress of contaminants and chemicals from the outside. This gives totally effective chemical and oil resistance over a wide range of products which is confirmed by the water pick up test and a more stringent test involving battery acid.

How do other hoses compare?

Some hoses try to "fool" the test by applying a thin membrane of latex or silicone to the cover. Even though new hoses may pass the specified water pick-up test, unfortunately this coating can be easily ruptured on flexing or destroyed by chemicals exposing the textile to further attack. Only Duraline has its pin holes fully and permanently sealed.
