ASTM B705 is a standard specification for welded nominal tubes for nickel alloys (UNS N06625, UNS N06219, and N08825). The following is a detailed analysis of the standard and the alloy pipes involved: 1. Overview of the standard Standard number: ASTM B705 Coverage: This standard covers welded metric tubes for UNS N06625, UNS N06219 and N08825 nickel alloys under annealed conditions (tempering). Second, the main requirements The ASTM B705 standard mainly specifies the following: Chemical Composition: The chemical composition requirements for each alloy are detailed to ensure that the material of the tubing meets the standard. Mechanical properties: The mechanical properties of the tube, such as tensile strength, yield strength, etc., are specified, and the test methods and acceptance standards are given. Size and tolerance: The size requirements such as the outer diameter and wall thickness of the pipe and the allowable deviation range are clarified to ensure the dimensional accuracy of the pipe. Manufacturing & Inspection: The manufacturing process of the tube is regulated, including the welding process, heat treatment, etc. The requirements for inspection and testing, including non-destructive testing, hydrostatic testing, etc., are specified to ensure that the quality and performance of the pipe meet the standards. Schedules and deviations: Schedules may be included in the standard listing the specific dimensions of the tubes and the allowable deviation ranges for the manufacturer’s and users’ reference. Third, the field of application Due to their excellent corrosion resistance and high temperature strength, these alloy welded nominal pipes are widely used in a variety of industrial fields, including but not limited to: Chemical: used to manufacture chemical equipment and pipelines with strong corrosion resistance. Oil & Gas: In the process of oil and gas extraction, processing and transportation, it is used to manufacture high-pressure, corrosion-resistant pipelines and equipment. Aerospace: used in the manufacture of engine parts, structural parts, etc. 4. Precautions When selecting and using alloy welded pipe under ASTM B705, parameters such as chemical composition, mechanical properties, dimensions, and tolerances of the product should be carefully checked to ensure that they meet actual needs. The selection and use of products should comply with relevant standards and norms to ensure the quality and safety of products. During use, attention should be paid to the maintenance and care of the product to prolong the service life of the product. In summary, ASTM B705 is an important standard specification for welded nominal tubes for nickel alloys (UNS N06625, UNS N06219, and N08825), which provides detailed specifications for the chemical composition, mechanical properties, dimensions, and tolerances of the product to ensure that the quality and performance of the product meet the requirements of the standard.Huanickel?related?products?strictly?implement?this?standard.?For?more?information?about?the?standard?and?the?corresponding?product?information,[email protected] |
