EEMUA 243 provides an overview of the selection, installation and maintenance of a variety of mechanical pipe connector designs which can be used as an alternative to hot work. 

The primary function of the connectors covered in this guidance is to join two pipes whilst maintaining pressure containment and not for the purpose of leak sealing or providing mechanical strength to a damaged section of piping. EEMUA 243 focuses on key points for Users to select the most appropriate mechanical connector for the specific application and when developing their maintenance and inspection strategies for these components post installation. 

The design of the mechanical connectors included in EEMUA 243 are often proprietary and are classed as ASME B31.3 Unlisted Components. For this reason, the User should work closely with the OEM when developing their strategy, while using this guidance to supplement their knowledge and considerations. The remit of EEMUA 243 does not cover threaded fittings, flanged joints, or mechanical clamp repairs (as defined by ASME PCC-2). 

This publication was developed by engineers who work exclusively in the oil and gas sector, as well as OEM technical specialists. Although the use of EEMUA 243 was originally targeted for the topside and upstream industry, it is recognised that it may be applicable to a range of other industries including: shipping, mining, steel, chemicals, nuclear, water, and food and beverages. It is expected that the reader will have a basic competency in piping design.
