The repair of dents in an operating line presents the pipeline engineer with a difficult problem: should it be cut out, sleeved and the sleeve infiltrated with epoxy grout to prevent the dent from flexing, or can it be left as is. Obviously, being…
The application of requirements contained in many industry codes and standards requires some interpretation by the user and by the regulator who is called upon to enforce their use. There are often differences in the way requirements are interpreted…
This document describes the evaluation of the use of internal pipeline coatings. The evaluation includes a software tool suitable for comparison of net present value of various coating options.
The work described in this report focuses on the development of data processing routines for curved-wide-plate (CWP) tests, the presentation of test results in a consistent and unified format, generation of fracture resistance curves from, and the…
This report provides a review of the state-of-the-art knowledge on glycol-water mixtures carried over to dry gas transmission pipelines, i.e., physical properties, the causes of entry, and the corrosiveness. Findings obtained from literature…
This work (1) performed a literature review of existing test procedure and protocols, (2) an associated workshop to evaluate subject matter experts of the key element of the Recommended Practice and a discussion of the Technical issues, and (3)…
This study was focused on determining the effects of thermal radiant energy on ultrasonic meter accuracy at flow rates less than 10% of meter capacity. A straight run ultrasonic meter installation consistent with the recommendations of AGA Report…
Due to the uncertainty in the viscosity correction factors pumps can be over or under-sized. The error in the correction factors is not known, since tests have not been completed to verify the performance of pumps at the higher flows and heads.…
The objective of this report is to investigate failure pressure predictions made by common assessment methods used by the pipeline industry, such as ASME B31G, Modified ASME B31G, RSTRENG and others against recorded burst test pressures. The analysis…
This report summarizes a PRCI research project aimed at evaluation of the effects of anisotropy and the shape of pipe steel stress-strain relationships on pipeline strain demand for X80 and X100 UOE pipe. The research included: a review of pipeline…
