Dräger Hose FKM

Description

Dräger Hose FKM works with the Draeger multi gas meter and pump. It is extremely easy to use: insert the Dräger MicroTubes, start measuring, then read out the test result. Add the Dräger Pump connected with this Coupler for X-act 7000 to extend fire department and hazmat capabilities.

Draeger Hose FKM helps test for hazmat substances that can be measure in the ppb range, in hard to reach places like pipes, ducts, and tanks up to a distance of  147.6 feet (45 meters). With the Draeger multi-gas detection monitor also gives first responders precise results right on site. This replaces slow, expensive lab analyses.

Dräger sampling hoses for portable gas detection devices

Working in confined spaces and containers like pipelines, silos, ducts and shafts is part of everyday operations in many industries. But before maintenance, cleaning or repairs can take place inside these spaces, any risks facing the workers must be minimised. In general, a risk assessment will determine which specific risks might occur. Common risks include concentrations of toxic or explosive gases and fumes, as well as life-threatening oxygen depletion.

To prevent accidents and protect workers, these confined spaces and containers must be cleared for entry. That means checking and analysing the concentrations of any hazardous substances that may be present. This is done from outside by using sampling hoses that can be connected to compatible multi-gas detection devices. These hoses enable you to take in gas samples and test them remotely without exposing the testing crew to hazards.

TIME IS A RELEVANT FACTOR DURING TESTING
Before each test, the sampling hose must be flooded with the air sample to be tested. The flooding phase is intended to eliminate any interfering factors such as “dead volumes”. Flooding times vary depending on the type and concentration of gas or vapour being tested, as well as the material, length, diameter and age of the testing hose. As a rule of thumb, this approach is recommended: With a dry, brand-new hose, allow the hose to be flushed for about 3 seconds per metre.

During the testing phase, The narrower the hose diameter, the faster the results will be available. For a volume flow of 0.3 l/min, a standard gas such as methane, oxygen or carbon monoxide only takes 1 about 5 seconds to pass through a 10 m hose with an inner diameter of 3 mm. Under the same conditions, it takes the same gas as long as 40 seconds to pass through a 10 m hose with an inner diameter of 5 mm – in other words, almost 3 times longer. The table below shows other testing times for hose lengths of 10 and 45 metres, at three different volume flows and an inner hose diameter of either 3 mm or 5 mm. In all these cases, the 3 mm hose works more than twice as fast as the 5 mm hose.
