Abstract
Processes and systems for preparing pipe for machine processing to form pin and box ends for assembly into pipelines using mechanical press-fit pipe joints that are fully measured and documented during both manufacturing and assembly. Installed pipelines include pipeline data monitoring systems coupled to a pipeline data management center for receiving, archiving, and analysis of the data records to aid in administration, operation and management, and troubleshooting of pipelines.
Claims9
A process, carried out on a bench having a stationary pipe clamp on a first end and a hydraulic ram for operating a movable tooling support on a second opposite end for preparing pipe sections for assembly in a pipeline using mechanical press-fit pipe joints to join the pipe sections, comprising the steps of:
- performing a pre-preparation process for each section of taw pipe;
- forming respective pin and box ends of each section of pipe for joining using the mechanical press-fit pipe joints;
- measuring and storing parameters for hydraulic pressure P and displacement length L associated with forming the pin and box ends of the pipe sections using a process monitoring computer system, wherein a data record of the at least two parameters of the formation of each pin and box end is created and stored;
- marking each pin and box end of each pipe section with a permanent encoded data panel recording identification and end preparation data for the associated pin or box end;
- and
- coating the formed pipe sections according to specifications applicable to the expected use of the pipe sections in a pipeline.
