On-site hydrostatic testing for Doosan Babcock

Civil Nuclear


Doosan Babcock develop and offer sophisticated and innovative technology products and skills to help manage the challenges of the nuclear industry.

Tyne Pressure Testing has provided on-going, on-site hydrostatic testing and leak testing on fabricated stand pipes for Doosan Babcock.

The purpose of this testing was to verify the structural integrity of the stand pipes for use in a nuclear power station and to ensure that the components met industry standards BS EN 13480-5 and ASME B31.3.

Tyne Pressure Testing invested in various equipment to enable on-site testing including a transportable container which houses a pump, booster and data loggers. The container is fully self-sufficient, relying solely on air compressors to operate, with the structure acting as a safety barrier between the on-site engineers and the testing, allowing on-site testing in most circumstances.


The testing was carried out over several months at the Doosan Babcock facility. During testing, the stand pipes were placed within the restricted area and subjected to hydrostatic testing to varying pressure up to 261 Bar. A filtration system was employed to distil the water used ensuring that the components were not damaged by chemicals present in unfiltered water, such as chlorine. High pressure gas testing, otherwise known as leak testing, was also carried out to ensure that the pipes are leak-proof.

A Tyne Pressure Testing engineer was present on-site at Doosan Babcock daily to oversee the project from the safety of the container. Where required, night shifts minimised disruption within the facility and ensured that all tests were carried out within the client’s schedule.

Tyne Pressure Testing tested multiple pipe spools which supported the successful delivery of a significant project to a major client of Doosan Babcock.
