Workshop tests on the ø3000 Howell-Bunger valve
We recently conducted the corresponding workshop tests on a Ø3000 Howell-Bunger valve designed to work at a depth of 106 m.The tests, with highly satisfactory results, were conducted under internal pressures of 10.6 bar (leak test) and 15.9 bar (stress test). The force exerted on the blind flange designed for testing during the stress test was […]
