3431 Guidelines for the management of access fittings for pressurised systems

Overview:

This guidance provides principles and good practice associated with the integrity management of intrusive access fittings. The document covers the life cycle from the design, application, registration and safe handling of the different types of fittings through to abandonment/removal. The types of degradation which can be expected are detailed as well as methods of monitoring and the maintenance required.

This guidance covers intrusive access fittings for corrosion and erosion monitoring, chemical injection and fluid sampling in all systems, but excludes fittings for instrumentation and process control which should be managed within their own scheduled maintenance strategy. It also excludes non-intrusive devices such as ultrasonic testing (UT), subsea monitoring units and acoustic probes and data collection devices. In addition, it does not consider the validity and analysis of data which should be considered within the overall integrity management of the system to which they are installed. This document is not intended as a guide to the specifics of handling or operating access fittings, as those details should be provided by the OEM.

This document is not intended as a guide to the specifics of handling or actuating access fittings, as those details should be provided by the original equipment manufacturer (OEM).
