Several components in geothermal power plants need to be protected from the environment due to the corrosive nature of geothermal fluids used to generate the energy. Depending on the fluid properties for any location, the type of protection varies. In geothermal power plants, wear, erosion, corrosion, and scaling are all known problems1. These issues can lead to a variety of outcomes, ranging from decreased plant efficiency to upstream component failure. Failure of a component is thus a significant challenge in the geothermal industry, where materials need to operate in high temperature and high pressure environments. A major cost factor is also linked to the drilling of geothermal wells, where cost rises due to increased depth/distance of drilling, increased trip times, higher high temperature and high-pressure conditions which can lead to increased wear and corrosion of the materials. To address the issue, coatings can be considered to be a potential solution to extend the service life of downhole equipment.

The austenitic alloy UNS N08935 has been developed to offer high resistance to corrosion in various environments – especially those containing high levels of chlorides or acid components. It can be an interesting alternative to conventional Ni-based alloys, due to its relatively low Ni-content at 35% by weight. In applications where thick gauges are required, it may be beneficial to utilize clad material – i.e., a thin layer of corrosion resistant alloy (CRA) bonded to a thicker gauge of a less costly backing material (typically carbon steel). In this work, explosion clad plate with a UNS N08935 CRA layer has been produced and evaluated to characterize the effect of the bonding process and heat treatment on the material properties. Prior to explosion bonding, two UNS N08935 plates were welded together (GTAW, groove weld, ENICRMO-13 filler metal) to simulate pre-cladding processing. The resulting welded plate was explosion bonded to SA516-70N carbon steel, and the effectiveness of the bonding process was confirmed via automated ultrasonic inspection of 100% of the clad surface. Mechanical testing at various locations was performed in order to characterize the strength of the UNS N08935 / carbon steel bond. Material properties of the CRA layer, in both the welded and unwelded condition and before and after heat treatments simulating subsequent processing steps for the bonded plate, have been evaluated in terms of microstructure and corrosion resistance.

From 6Mo To Ni-Base – Characterizing The Corrosion Performance Of Two Important Material Groups

Product Number: 51322-17935-SG

Author: Björn Helmersson

Publication Date: 2022

$20.00

Stainless steels and Ni-base alloys are often considered as construction materials in applications where highly corrosive conditions are expected. High levels of halides, low pH and high temperatures are factors that often contribute to the selection of such materials.

Ten different alloys have been included in this work, representing a range of highly alloyed stainless steels and Ni-base alloys. The purpose has been to evaluate the corrosion resistance of stainless steels with alloying content in the 6Mo range or higher, and competing Ni-base materials. The austenitic grade N08904 and two super-duplex grades have also been included for reference.

ISO 27913 - Example for Successful Standardization Activities in the Field of CCUS

Product Number: 51324-20592-SG

Since 2016 ISO Technical Committee (TC) 265 is working on standardization the whole CCS-process chain. Around 30 countries are working together to provide international guidelines. As ISO 279131 was the first standard finished within these activities it is already in the stage of first revision. The objective of ISO 27913 is “to provide specific requirements and recommendations on certain aspects of safe and reliable design, construction and operation of pipelines intended for the large-scale transportation of CO2 that are not already covered in existing pipeline standards such as ISO 136232, ASME B31.83, EN 15944, AS 28855 or other standards. Existing pipeline standards cover many of the issues related to the design and construction of CO2 pipelines; however, there are some CO2 specific issues that are not adequately covered in these standards. The purpose of this document is to cover these issues consistently. Hence, this document is not a standalone standard, but is written to be a supplement to other existing pipeline standards for natural gas or liquids for both onshore and offshore pipelines. This contribution shall provide information on the content, the current stage of the revision process, encourage to contribute to this standard and make listeners aware to consider the influence of ISO standard on documents currently in draft.
