Blind Flange For Hydrotest

A hydrostatic test could be a method during which pressure vessels like pipelines, plumbing, gas cylinders, boilers and fuel tanks may be tested for strength and leaks. The check involves filling the vessel or pipe system with a liquid, sometimes water, which can be bleached to help in visual leak detection, and pressurization of the vessel to the desired check pressure. Hydrotest blind flange pressure tightness may be tested by closing off the availability valve and perceptive whether or not there’s a pressure loss. the placement of a leak may be visually known additional simply if the water contains a colorant. Strength is typically tested by measurement permanent deformation of the instrumentation. hydraulics testing is that the most typical methodology used for testing pipes and pressure vessels. victimization this check helps maintain safety standards and sturdiness of a vessel over time. freshly factory-made items are at first qualified victimization the hydraulics check. they’re then re-qualified at regular intervals victimization the proof pressure check that is additionally known as the changed hydraulics test. Testing of pressure vessels for transport and storage of gases is incredibly necessary as a result of such containers will explode if they fail harassed.

The Steel Flange manufacturers in India Produce these flange in O.D. & thickness based on ASME rating and line size for isolation or hydrotest blinds.

Hydrotest blind flange can be purchased in sizes up to 96″ are available. Many thickness, rating or alloy can be produced upon request.

Includes both MSS SP44 Series “A” and API-605 Series “B” ratings.
