Flange Weld Testing

Flange Weld Testers (FWT’s) are used for hydrostatic testing of the integrity and tightness of new and / or old welds, without requiring a full system test to be performed. By creating a test chamber around the weld it is not necessary to flood the whole system with water (or another test medium). FWT’s are used in many systems, including pipelines, pressure vessels, etc. Because only part of the pipe, i.e. until the weld, is used as test chamber it is not necessary to clean the entire pipe.

All our flange weld testers are tested in-house, certified and ready for mobilisation within a short time within South-East Asia. Petracarbon’s Weld Tester’s are available in two forms: Flange Weld Testers (FWT) or internal weld testers (IWTs). These can be utilised to perform localised pressure testing of existing or new flange welds, effectively reducing the tedious requirement to flood the entire system. Petracarbon offers efficient, safe and cost-effective solutions to pipeline operators.
