Leak testing may be performed on any process pipework or system to prove the integrity of all flanged joints, welding joints, fittings & valves before the introduction of live systems contents. Process systems are typically tested during the initial commissioning stage, and then subsequently after each further intervention to prove that any disturbed joint has been correctly reinstated. The advantage of hydrotesting of any process facility is that it will reduce loss of production through unplanned shutdown to repair leaking joints. The safety of any facility that has been leak tested is enhanced through the elimination of potential escape of flammable, toxic, or asphyxiating system contents. Environmental performance is improved through the elimination of hydrocarbon and hazardous product releases into the atmosphere. Our personnel are multiskilled. We can combine our bolting/flange management service with hydro test to create a significant reduction in headcount, schedule, and costs. AWI offers hydro testing pressure up to 20,000 psi, with flow rates up to 4 gallons per minute. Pneumatic or electrically driven hydro testing is available. All units are supplied with certified slings and are approved for offshore use.
