Corrosion & Mechanical Properties of Nickel Based Alloy 825 Explosion Welded Plates for H2S Service

Product Number: 51323-19123-SG
Author: O. Sarrat, H. Alves, J. Botinha, P. Maas
Publication Date: 2023
$20.00

The total project study focused on six suction and discharge drums. Each of them was built with twohemispherical heads and a number of shells. The H2S service and Stress Corrosion Cracking (SCC) from this specific oil and gas field required the equipment to be cladded with Alloy 825 to protect them from corrosion.

Design Consideration for Internal Welding Attachments in Clad Pressure Vessels

Product Number: MPWT19-14326
Author: Olivier Sarrat
Publication Date: 2019
$0.00

Process equipment which employs a corrosion resistant alloy (CRA) layer cladded to steel is common in refineries, petrochemical plants and other plants processing highly corrosive media. There are two regularly employed methods for welding attachments and internals to clad process vessels. One is to remove the CRA cladding for welding the attachment to the steel base metal assuming dissimilar welds and restoring CRA by weld overlay. The other eliminates the step of removing the cladding, simplifying the attachment process by direct welding of the internals onto the clad layer. With the lack of data to prove the integrity of direct welding attachment onto the clad layer, designers frequently demand the cladding be removed or allow only a conservatively low stress limit for what can be attached directly to the clad surface. It is well understood that eliminating the step of removing clad increases the simplicity, improves the lead-time, and reduces the cost of making these attachments for trays or other internals, but there are concerns about clad disbonding risks. With the aim to provide data around the integrity of direct welding attachments for better risk assessments, a technical study was undertaken. In this study, it will be shown that the bond between clad material and the base steel is robust enough to withstand the heaviest attachments and harshest conditions. The theory behind the technical study will be presented along with the results of this study

The alloys used as clad material for this study are members of the so-called “C-family”. It consists of Ni-Cr-Mo alloys, which are known for combining the corrosion resistance of Ni-Cr alloys in oxidizing media with corrosion resistance of Ni-Mo alloys in reducing media. As a result, these materials have proven to be extremely durable in a wide range of highly aggressive media. The development of these materials started in the 1930s with Alloy C. This alloy showed remarkable corrosion resistance in a wide spread of media, low sensitivity for pitting or crevice corrosion and virtual immunity to chloride induced stress corrosion cracking.
