One configuration has two functions: it can both leak seal and timely discharge liquid.
The sealing film in the transportation package can be fixed under the inflation sleeve on the pipeline to correct any unevenness that may occur during inflation.
The test pressure is 1.3 times the maximum operating pressure.
Acid resistant drainage hose with stainless steel interceptor.
When supplying, the flange drainage bag set is stored in a portable transport box of 800 * 600 * 120mm, which is more convenient.
Product Description
The German VETTER 1.5 bar flange drainage bag is specifically designed for sealing leaks and liquid drainage at flange or pipeline joints. Place the flange drainage bag in the leakage area to fully seal both sides of the flange and pipeline with the inflation sleeve, and then seal the flange drainage bag by using gas and liquid leak proof pull and twist buckles. After inflating the drainage bag, dangerous substances can be easily discharged through stainless steel ball valves and acid resistant drainage hoses.
The 1.5 bar flange drainage bag is equipped with two functions: it can both leak seal and timely discharge liquid. The sealing film in the transportation package can be fixed under the inflation sleeve on the pipeline to correct any unevenness that may occur during inflation. The test pressure is 1.3 times the maximum operating pressure, and the acid resistant drainage hose is equipped with a stainless steel interceptor.
