REQUIREMENTS FOR LOW ALLOY STEEL PIPING ATTACHMENT WELDS

Product Number: MPWT19-15315
Author: Ameer Hamza, Jignesh Desai, Jan-Willem Rensman, Mark Van Den Broek, Kuntak Daru

Proper design and fabrication, heat treatment and inspection practices play a vital role in achieving good quality and performance of low alloy steel piping. These materials have narrower fabrication windows as the alloy content goes up and non-adherence to correct execution practices may lead to leakage by delayed hydrogen cracking, stress corrosion cracking or fatigue resulting in unplanned shutdowns and costly repairs.
This paper describes details about strengths and weaknesses of support design and fabrication practices for such attachment welds. The paper discusses various precautions to be taken during the design and fabrication stages for low alloy steel supports attachment welds. It will discuss heat treatment cycles viz. preheat, interpass, dehydrogenation treatment (post heating) and post weld heat treatment (PWHT). The control of consumables, welding environment conditions, and the weld heating cycle is essential to prevent hydrogen assisted cold cracking in high hardness microstructures in weld and HAZ, and for achieving successful relief of residual welding stresses.

Air Cooler Plug Gaskets Leakage During Startup

Severe leakage on a high percentage of the plug gaskets on a high alloy air cooled heat exchanger during or shortly after initial startup has occurred in only a small percentage of air coolers, but has resulted in costly replacements and unit shutdowns. These problems have occurred with 304L stainless steel (SS), 316L SS and Nickel 200 gaskets, although each material also has many successful applications. The contributing factors to the leakage has included corrosion, galling and/or inadequate manufacturing steps. This paper summarizes a number of case histories and gives their root causes and solutions. The pros and cons of various gasket materials and design options are discussed, along with a proposal for additional requirements to be added to industry standards which would minimize the risks of these problems.

The increasing demand for energy has brought a pressing need to reduce our reliance on regular fossil fuels as they are a primary source of greenhouse gas (GHG) emissions. The continued use of these fuels has resulted in an anthropogenic based increase in global warming, climate change, and other environmental challenges. To tackle these issues, it is essential to shift towards alternative sources of energy that are renewable and sustainable, and that can provide a pathway to stated decarbonization goals.

It is well known that H2S promotes hydrogen entry into steels that may result in many types of steel failures. This paper examines the influence of traces of oxygen on corrosion and hydrogen charging of steel in an H2S containing environment.

By far, the microbiological species most associated with corrosion has been Sulphate-Reducing Bacteria (SRB).  Majority of Microbiologically Influenced Corrosion (MIC) research has focused on the activities of this type of bacteria. One of the primary reasons for this has been the presence of iron sulfides in corrosion products associated with MIC. SRB reduce sulfates to sulfides, which then react with iron and steel. However, an accepted fact is that MIC is also caused by the action of the biofilm produced by bacteria, in a similar way to under-deposit corrosion. 

The primary method used to prevent MIC in the oil and gas industry is by use of biocides. The criteria used for selection of biocides is often their proficiency to kill SRB. The danger with this is that one can neglect the ability of other bacteria frequently found in oil and gas environment, such as general aerobes and general anaerobes to cause corrosion by biofilm production. This became evident when severe general & pitting corrosion was observed in two oil and gas separators in one of the facilities in Kuwait Oil Company (KOC), where SRB levels were zero but significant numbers of sessile and planktonic general aerobes and general anaerobes were found to be present in the process. 

Using microbiological and chemical analysis, the mechanism of this type of MIC, specially the relationship between the quantity of various biofilm-forming bacteria and nature and magnitude of corrosion has been studied and the findings are presented in this paper.

The integrity of new pipeline projects is critical to Saudi Aramco to avoid any short or long-term impact on the supply of energy. During construction activities, pipeline internal welding inspection is carried out in compliance with international and Saudi Aramco requirements. The visual inspection of internally cladded girth welded pipes requires extra care to avoid any improper field fabrication errors during welding, especially at the root pass area. Such errors can limit the inspection capability and compromise the integrity of pipeline network with possible degradation of corrosion resistance at/near the weld rot, resulting in premature failures. Currently, projects utilize conventional tools such as borescope which is time consuming with limited inspection capabilities (up to 150 meters inside the pipe) and system maneuverability at inspection locations.
The Saudi Aramco Inspection Department enhanced their active inspection technology program and collaborated with a local technology developer. They trialed a wireless crawler robot, which is a high resolution remotely operated robot capable of inspecting internal girth welds with 5000 meters travel capability inside the pipes. The robot can inspect internal girth welds in the field, and inside pipelines with internal diameters of 6 inches and above, and wirelessly transmits the visual inspection results to the outside control room for a timely assessment and critical decision making. The internal visual inspection with wireless crawler robot will help in improving the project progress, reducing repair costs, by identifying defective welds before coating application.
