Third Party Inspection Services Technical Articles. The technical articles on this website are focused on third party inspection services and are beneficial for:The Importance of Correct Post Weld Heat Treatment (PWHT api 620 vs api 650 impact resistance Strip surfacing weldingWelding is one of the most critical processes in the manufacture of pressure vessels like the boiler of a thermal power plant. The temperature of the molten weld pool during the process is in the range of 2000 deg C. The heat increase is rapid and instantaneous. When this small strip of molten pool cools down the shrinkage results in thermal stresses that are locked up inside the metal. This also can change the macrostructure of the steeSee more on brighthubengineering api 620 vs api 650 impact resistance Strip surfacing weldingThe Heat Treatment of Inconel® 718 | 2019-06-05 api 620 vs api 650 impact resistance Strip surfacing weldingThe term superalloy was coined just after World War II to describe that group of alloys developed specifically to extend the life of aircraft turbine engines and turbosuperchargers so as to offer better performance life at elevated service temperatures.[1,2] Today, superalloys (aka high-performance alloys) are those materials engineered for extreme-duty environments where high levels of mechanical strength and creep resistance at higSee more on industrialheating api 620 vs api 650 impact resistance Strip surfacing welding

2: Does API 650, Section. 2.5.2 preclude the use of electric-resistance welded pipe meeting ASTM A 53, or electric- welded pipe meeting API 5L, for nozzles in shells made from Group IV, IVA, V, Stress-relieving is needed after weldingStress-relieving is the process generally specified after welding of most materials.. Removing or reducing the residual stresses generated by welding is required for improving the dimensional stability of weldments.. In certain applications, internal residual stresses can sum up with those generated by externally applied loads..

Steel pipes are cylindrical tubes made from steel that are used many ways in manufacturing and infrastructure. Theyre the most utilized product made by the the steel industry. The primary use of pipe is in the transport of liquid or gas undergroundincluding oil, gas, and water. However, pipes of varying sizes are used throughout api 620 vs api 650 impact resistance Strip surfacing weldingSome results are removed in response to a notice of local law requirement. For more information, please see here.Repair or Alteration of Pressure VesselsThe most frequent contact with these vessels as a repair organization or inspector is the repair or alteration of over-the-road liquid petroleum gas (LPG) transport vessels. The information contained in this article pertains to vessels fabricated utilizing Code Case 1204-11 or Section VIII, Div. 1, Part UHT, depending on the year built. Repairs api 620 vs api 650 impact resistance Strip surfacing weldingPostweld Heat Treatment Code Exemption - Pt 1 - TWIPost-weld heat treatment (PWHT) is applied to steel assemblies primarily to reduce the likelihood of brittle fracture by reducing the level of tensile welding residual stresses and by tempering hard, potentially brittle, microstructural regions. For large steel assemblies in particular, PWHT can be an expensive operation, and there is thus an economic incentive to avoid PWHT, wherever possible. Whether PWHT is necessary depends on the fracture toughness at the minimum service temperature, the stress levels anSee more on twi-global api 620 vs api 650 impact resistance Strip surfacing welding

The influence of flux formulation, and electrode and skelp composition on the notch toughness of spiral and skelp end welds in 0.540in WT and 0.720in WT pipe has been investigated. It has been shown that: . The oxygen potential of the flux formulation employed has the Materials - Corrosion and Corrosion AllowanceA tank wall required a 5 mm wall thickness for mechanical considerations. The designer has determined that the corrosion rate will be 0.4 mm/yr and the expected life of the tank will be 10yr. The total corrosion allowance is the corrosion rate per year (0.4 mm x 10 yr = 4 mm). The corrosion allowance is doubled to 8 mm as a safety consideration.Material selection and product specification api 620 vs api 650 impact resistance Strip surfacing weldingSteel material is supplied in two product forms flat products (steel plate and strip) and long products (rolled sections, either open beams, angles, etc or hollow sections). For structural use in bridges these products are inevitably cut (to size and shape) and welded, one component to another.In the structure, the material is subject to tensile and compressive forces.
