Patent number: 11965819Abstract: A method is provided for determining whether post-weld heat treatments should be required for external attachment welds in applications where stress corrosion cracking is a possibility. According to the method, residual stress values are measured in test samples welded at high input heat levels and test samples welded at low input heat levels for a variety of different wall thickness. A threshold residual stress level is determined according to a method of selecting a common pipe used in industry and measuring the residual stress level in the longitudinal seam of the pipe. The measured residual stress values for the high and low heat input welds are compared against the threshold to determine whether for a particular wall thickness, the high and low input data exceeds the threshold, indicating whether post-weld heat treatments are required.Type: GrantFiled: August 3, 2021Date of Patent: April 23, 2024Assignee: SAUDI ARABIAM OIL COMPANYInventors: Tariq A. Alghamdi, Rashid D. Al-Hajri

Patent number: 11585187Abstract: The disclosure describes hydrocarbon flowline corrosion inhibitor overpressure protection. Such a protection system includes a fluid flow pathway fluidically coupled to a corrosion inhibitor injection pump that injections corrosion inhibitor into a hydrocarbon carrying flowline. When the injection pump pressure exceeds a threshold flow pressure, the corrosion inhibitor is flowed through a first branch of the fluid flow pathway to relieve the excess pressure. The first branch is fluidically isolated from a second branch. When a rupture disc in the first branch fails, then the corrosion inhibitor is diverted to flow through the second branch and the first branch is isolated from the corrosion inhibitor flow.Type: GrantFiled: April 20, 2021Date of Patent: February 21, 2023Assignee: Saudi Arabian Oil CompanyInventors: Fathi BuGubaia, Khalid Al Ghamdi, Mohammad R. Khunaizi, Rashid D. Al Hajri, Khalid Al Subaie, Zayed Qahtani
