ASTM B626 is a standard specification for welding nickel and nickel-cobalt alloy pipes, and the following is a detailed breakdown of the standard: 1. Overview of the standard Standard number: ASTM B626 Scope of application: The ASTM B626 standard regulates the requirements for welded pipes made of nickel and nickel-cobalt alloys, covering a variety of alloy grades, such as UNS N10001, UNS N10242, UNS N10665, etc. Second, the main requirements The ASTM B626 standard specifies in detail the following aspects for welding nickel and nickel-cobalt alloy tubing: Chemical composition: The content range of various elements in the alloy is specified to ensure that the chemical composition of the product meets the requirements of the standard. Dimensions: Covering the outer diameter, wall thickness and other dimensions of the pipe to meet the needs of different applications. For example, pipes can range from 1/8″ to 31/2″ (3.2 to 88.9 mm) with outside diameters from 0.015″ to 0.148″ (0.41 to 3.7 mm). Mechanical properties: including test methods and requirements for tensile strength, yield strength, elongation and other indicators to ensure that the mechanical properties of the product meet the needs of use. Manufacturing process: It covers the requirements of the welding process, including the quality control of welding methods, welding materials, welded joints, etc., to ensure that the manufacturing process of the product meets the standard requirements. Inspection and testing: It stipulates the inspection and testing methods of products, including chemical composition analysis, mechanical property testing, dimensional measurement, hydrostatic testing, etc., to ensure that the quality of products meets the standard requirements. Third, the field of application ASTM B626 is a standard specification for welding nickel and nickel-cobalt alloy pipes that are widely used in various fields such as: heat exchanger Condenser tubes Energy and chemical industry 5. Precautions When selecting and using ASTM B626 welded nickel and nickel-cobalt alloy tubing, ensure that the product meets the requirements specified in the standard. In the process of processing and use, the relevant safety operation procedures and standards should be strictly adhered to to ensure the safety of personnel and equipment. As technology continues to advance and the market continues to evolve, the ASTM B626 standard may also be revised and updated. Therefore, when using the standard, attention should be paid to its latest version and revisions..Huanickel?related?products?strictly?implement?this?standard.?For?more?information?about?the?standard?and?the?corresponding?product?information,[email protected] |
