EEMUA 143:2017 PDF Download

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.
