This recommended practice covers the weld fabrication of connectors and handling attachments such as lift eyes and landing pads to pipe.

This document includes practices currently being implemented by a broad spectrum of the industry. This recommended practice is intended to be analogous to API 6A PSL 1 with additional requirements specific to the equipment fabrication.
