HOUSTON – Petrobras and ConocoPhillips have signed up to a joint industry project (JIP) concerning certification for additively manufactured (AM) industrial parts.

Lloyd’s Register (LR) and TWI in the UK have been running the program for just over a year, examining how to achieve code compliance for AM materials.

Currently no codes or standards exist to provide guidance for assessment of AM materials and their performance in the oil and gas industry.

Aside from the two new sponsors, Swiss flow control specialist Sulzer has also joined the JIP. Existing sponsors are Chevron, Sellafield, AECC BIAM, and AVIC MT.

David Hardacre, Project Leader for LR, said: “As more companies look to AM as a way to reduce asset downtime through the production, repair, and replacement of safety-critical parts, it’s clear they also need to ensure that these parts are compliant with the relevant regulations, codes and standards, which differentiates our project.”

The JIP will seek to deliver material property data and understanding of 316L type stainless steel used in three AM processes: powder bed fusion (PBF), wire arc AM (WAAM), and laser metal deposition (LMD).

Phase one of the project, already completed, involved:

1.) Assessing standards selected by members of the sponsor group

2.) Defining test coupon geometries and associated cutting plans for test specimens

3.) Producing test plans for powder and wire feedstocks

4.) Specifying requirements for mechanical and metallurgical testing, and numerical modeling of the PBF and WAAM processes to facilitate development of the build parameters.
