EEMUA出版物143旨在帮助确定管端焊接的适当技术和限制。EEMUA 143通常由采购工程师、指定人、设计师或材料工程师使用。第二版将ISO 15614-8:2016作为主要来源，并在多个领域为用户提供了进一步的澄清。其中包括:每种接头类型的使用限制；测试程序和焊工资格的要求和实用性；关于管和管板制备的建议；预热和层间温度最大值指南；焊接参数和检验和试验计划（ITP）的附加控制。第一版旨在为热交换器管和管道之间的焊接接头的设计、制造、检查和测试建立标准化程序- 盘子。

EEMUA Publication 143 is designed to help identify the appropriate techniques for and limitations of tube end welding. EEMUA 143 would typically be used by a procurement engineer, specifier, designer or materials engineer. This second edition takes ISO 15614-8:2016 as the primary source and adds further clarification for the user in a number of areas. These include: the constrictions of use of each joint type; requirements and practicalities for testing procedures and qualification of welders; recommendations on the preparation of tubes and tube-plates; guidance on maximum values on preheat and interpass temperatures; additional controls on welding parameters and on the Inspection and Test Plan (ITP). The first edition was produced to establish standardised procedures for the design, fabrication, inspection and testing of welded joints between heat exchanger tubes and tube-plates.
