Hose lines are subject to special requirements when used for handling chemical substances, toxicants or gases or are possibly exposed to high temperatures.
Therefore ready-assembled hosepipes are also work equipment as defined by the new operational reliability regulation and are subject to the European pressure equipment directive 97/23/EG.
Where they are a permanent installation, they can form part of a plant that is subject to official control. Under certain conditions, hose lines are required to bear the CE marking! Temperature, pressure, abrasion, wear and ageing can lead to failure and so constitute a source of danger to life and limb.
It has therefore been recognized that only tested and thus reliable hose lines are a guarantee for safe operation, which in the final analysis will save on operating costs.
The state of the art is reflected in standards, recommendations and regulations.
Compared to former years, the assembly, repair and testing of such hosepipes may only be carried out by competent personnel such as "a qualified person in accordance with the operational dependability regulation for pressure vessels and pipelines" It goes without saying that a number of our employees have this qualification, and other employees are
"certified specialist consultants for hoses & fittings".
We manufacture hose lines for all conceivable applications, such as e.g. water, steam, chemicals, acids, solvents, petrol, hot bitumen, for aircraft fuelling, chemical works, ship loading operations, haulage companies, fire services ("GWG, AB Gefahrgut"), etc..
