Hi, As per ASME B31.3, Table A1-M,  -46 Deg Celsius is the minimum temperature applicable without impact test. But Please consider the below note description also before concluding. It is better to do an impact test below -29 degree celsius.

Dear, Yes, according to API 1104, if a pipe welder is qualified in the 6G position, they are generally considered qualified to weld in the 5G position as well. API 1104 typically covers welding standards and procedures for pipeline welding, and it doesn't specifically differentiate between 5G and 6G positions in terms of qualification requirements for welders. Therefore, a qualification in the more challenging 6G position typically implies proficiency in welding positions of equal or lesser difficulty, such as the 5G position. However, it's always essential to review the specific requirements of API 1104 and any relevant project specifications to ensure compliance.

Dear, Let's address each query with detail: 6" nozzles required RF pad or not? According to the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, specifically in UG-36, when the thickness of the vessel wall exceeds 10 mm (or 0.394 inches), reinforcement pads are typically required for nozzles larger than 2 3/8" ID. However, there are exceptions based on specific design considerations and loadings. In the case of the vessels you mentioned, if the thickness of the vessel wall where the 6" nozzles are located exceeds 10 mm, then RF pads may be required. The decision to use RF pads depends on factors such as the design pressure, vessel material, service conditions, and nozzle loads. RF pads help distribute the stresses and loads at the nozzle-to-vessel junction, enhancing the structural integrity of the vessel. Engineers and fabricators need to conduct detailed stress analysis and consider factors like nozzle loads, internal and external pressures, th...

Dear, Dual grade stainless steel, like 316/316L, refers to a type of stainless steel that contains a mixture of two grades within one material. In this case, 316/316L indicates a combination of 316 stainless steel and its low carbon version, 316L. 316 stainless steel is a widely used grade known for its excellent corrosion resistance, particularly in acidic environments. It's commonly used in industries like marine, chemical processing, and pharmaceuticals. 316L is a variant of 316 stainless steel with a lower carbon content, which enhances its weldability. This makes it more suitable for applications where welding is involved, as it reduces the risk of carbide precipitation and consequent corrosion in the heat-affected zones of welded joints. So, when you see "316/316L," it means you're getting the best of both worlds: the corrosion resistance of 316 stainless steel and the improved weldability of 316L. This dual-grade approach allows for greater versatility in vario...

Dear All, Design code – ASME B31.3, Welding Code- ASME BPVC SEC IX Material  to be used used during Fabrication - SA 333Gr6 (P No.1 Gr. 1) To SA 350-LF2 (P No.1 Gr. 2) Production Thickness range-5.54mm(Minimum)-9.53mm(Maximum) PWHT – Nil MDMT-= -45 Deg Cel. Kindly give your valuable suggestions for applicability of PQR impact requirement for above details. Pl.reply with code clause. Thanks & Regards Vinit India

Dear Vinit, For the applicability of PQR impact requirements based on the provided details, we need to refer to the ASME Boiler and Pressure Vessel Code (BPVC) Section IX, which covers welding qualifications. Since you're dealing with welding and materials in the context of ASME BPVC Section IX, the specific clause relevant to your scenario would be Clause QW-402.2. This clause outlines the impact test requirements for procedure qualification. Based on the information provided: Material: SA 333Gr6 (P No.1 Gr. 1) to SA 350-LF2 (P No.1 Gr. 2) Thickness range: 5.54mm (Minimum) - 9.53mm (Maximum) PWHT: Nil MDMT: -45 Deg Cel. Given these details, you would need to assess if impact testing is required for the welding procedure qualification. The decision would depend on factors such as the material specification, thickness, service conditions, and design requirements. According to ASME BPVC Section IX, if the design temperature is equal to or colder than the Minimum Design Metal Temperat...
