Internal
Corrosion Monitoring
and NDT Inspections |
The reason for internal corrosion monitoring may be different for many applications. As far as carbon steel is used under potentially corrosive conditions, internal corrosion monitoring is an important and useful purpose that can minimize risk, and help avoid failures and wrong allocation of assets. Other reasons may be the following:
· Requirement for safety reason
· Verification of integrity of process piping
· Optimization of corrosion control and mitigation
· Inspection planning program.
In the fight against corrosion, we provide internal corrosion monitoring services to enhance facility integrity. Effective monitoring principles are available to measure corrosion in these facilities which give actual conditions in a system and provide very reliable data for internal direct assessment.
We provide monitoring for the variety of needs that exist in the industry. Our clients are diverse industries, viz: Oil and Gas Production, Petroleum Refining, Pipeline and Power Transmission, Chemical Processing, Water and Gas Distribution, Manufacturing and Fabrication.
We supply a complete line of internal monitoring hardware, probes, instruments and tools including ER, LPR, coupons, sand/erosion probes, and monitoring devices. We identify the source, type and aggressiveness of the corrosion attack by focusing on direct, on-line techniques for internal corrosion rate monitoring.
· Corrosion Coupons: The weight loss coupon is the most basic monitoring technology where corrosion is determined from the weight loss over a period of time.
· Corrosion Probes: This technology utilizes a range of electrical sensors or probes (electric resistance - ER, linear polarization resistance - LPR) for real time monitoring. Data loggers are used for data collection and transferred to PC having the applicable software installed.
· Sand Erosion Monitoring: Production of sand related to hydrocarbon production can cause a devastating effect and severe erosion problems in pipelines and other process equipment.
· Process Variable Monitoring: pH Probe, Temperature Probe, Pressure Probe, Process Stream Sampling, Process Component Injection.
· Bacteria Monitoring: Bacterial Sampling and control, Bactericide Injection, Bacteria Build Up.
NDT Inspections:
CMS provide technology-based non-destructive testing (NDT) services to evaluate the structural integrity of industrial and public infrastructure, quality control, and material flaw detection and evaluation. We have competent managers, experienced engineers, skilled workers and courteous customer service. We combine the skill and experience of our certified technicians, engineers & scientists with our advanced software and other proprietary product offerings to deliver a comprehensive portfolio of solutions, ranging from routine to complex NDT inspections and plant asset integrity management. We serve a global customer base, primarily in the oil and gas, chemical, nuclear and other power generation, aerospace and defense, pharmaceutical, metal and metalworking and transportation industries. Through our approximately 1,500 employees in over 46 offices across 15 countries, we provide our solutions to a diversified customer base of leading global corporations.
We offer the following NDT systems utilizing Ultrasonics, and Eddy Currents at both land and swamp locations without the removal of pipeline coating.
· Automated Ultrasonic Testing (AUT)
· Long Range Guided Wave Ultrasonic testing
· Pulse Eddy Current (PEC)
· External inspection of above ground pipe with Robotic Pipe Scan (RPS) using Magnetic Flux Leakage (MFL) methodology.
· Circumferential and longitudinal compression wave ultrasonic wall thickness inspection of exposed pipeline section.
· Spot check inspection at the o’clock positions and at a given spacing upstream and downstream of exposed pipeline weld girth using ultrasonic wall thickness meter and USK7 scanning equipment.
· Spot check inspection at minimum of 4 positions (12, 3, 6, 9 o’clock) and at given intervals on de-coated pipeline or pipe fitting sections using D-meter and USK7 scanning equipment.
· Pit depth measurement of defective section of pipe using pipe pit gauge tool.
Internal Pipe Inspections:
Internal pipe inspection is an occasional requirement and should be carried out by pipeline operators. We offer the following internal pipe inspections:
· Internal visual inspection of pipe using internal remote viewing crawler tool.
· Internal corrosion inspection of pipe wall thickness and flaw detection using internal crawler tool.
· Internal inspection of pipe weld using internal crawler tool
