how to develop dissimilar metal or galvanic corrosion prevention

what is dissimilar metal or galvanic corrosion prevention? Corrosion is a process of damage to a material due to environmental influences. This is a natural process in metals. Corrosion in metals and equipment in the oil and gas industry results in financial losses, pollutes the environment and can endanger human safety. Engineers and scientists do a lot of research on corrosion to prevent and control the corrosion rates. On this occasion, we will discuss Galvanic Corrosion or known as dissimilar metal corrosion. This corrosion occurs when 2 different metal or alloy metals in the same environment and interconnected. This corrosion occurs because of the potential difference between the metals so that one metal functions as the anode and the other metal functions as the cathode. The principle of galvanic corrosion is the same as the electro-chemical principle of electrodes (cathodes and anodes), electrolytes and electric current. Metal that functions as[…]

IDMS Integrity Database Management System best practice 3 (asset management software)

IDMS integrity database management system best practice we will continue the previous article about IDMS integrity database management system best practice. Previously we talk about design code, inspection method involved and trending. now we will focus on Risk Based Inspection feature. IDMS integrity database management system best practice : upload Risk Based Inspection assessment One of Asset integrity Engineer job is conduct Risk based inspection for all fixed equipment. Risk Based Inspection assessment involve many job functions such as Asset Integrity engineer, Inspection specialist / API inspector, Corrosion engineer, operation folk and also IDMS Specialist. there are 3 type RBI methods i.e qualitative assessment, quantitative assessment and semi-quantitative assessment. In qualitative assessment, the SME (Subject Matter Expert) make a score of Pof (probability of failure) based on their expertise. They can say a carbon-dioxide pipeline is higher corrosive than a “high purity” crude oil pipeline.  They do not need to[…]

IDMS integrity database management system best practice 2 (asset management software)

integrity database management system best practice we will continue the previous article about IDMS integrity database management system. Previously we talk about design code and inspection method involved. now will focus on trending of inspection result.   IDMS integrity database management system – understanding trending In practice, the fixed interval of pressure vessel inspection is 5 years. UT inspector take measurement shell & head thickness at some location. we call it as TML, thickness measurement location. a IDMS data entry populate TML readings into IDMS software. IDMS software calculate short corrosion rate, long corrosion rate, remaining life, next inspection date based on half-remaining life method.   TML ID TML 001 required thickness 0.35 in inspection date 1-Jan-00 TML reading 0.525 in TML ID TML 001 required thickness 0.35 in inspection date 1-Jan-05 TML reading 0.510 in TML ID TML 001 required thickness 0.35 in inspection date 1-Jan-10 TML reading 0.505[…]

API Inspector job in Oil and Gas Industry

what is API inspector Job? API stands for American Petroleum Institute. the API manage certification programs called ICP. Since 1989, API’s Individual Certification Programs (ICP) have provided the petroleum and petrochemical industries with an independent and unbiased way to evaluate the knowledge and experience of technical and inspection personnel. These certification programs are based on the industry-developed standards that are recognized and used with confidence worldwide. Inspector, in general, means as an official employed to ensure that official regulations are obeyed. So API inspector is an inspector certified by API organization to ensure regulation for equipment is obeyed by the operating company. People who have an API certification can perform an inspection on company behalf and make a justification or recommendation for the equipment.   API inspector Job – API 570 Piping inspector API 570 Piping inspector jobs are conduct inspection and evaluation of in-service pipe. During the inspection, he[…]
