Flanges need to be sealed properly to prevent leakage and must also be cathodically isolated to prevent stray currents which cause corrosion and eventual breakdown of the metal. FT Gas continues to regularly receive sizeable enquiries and orders for Kleerband® #flange protectors. Designed to protect the flange face, studs and gaskets on raised face, full face and ring joint flanges from atmospheric corrosion, Kleerband® flange protectors are specified for deployment in #chemicalplants, #refineries, #gas plants, #offshore platforms, onshore #oilfields, metering stations, #water and #wastewater plants, pump stations and underground #pipelines. An additional, clear benefit is that visual inspection can be achieved without removing the flange protector.

Why are vents installed in trenchless cased pipeline crossings? Inside a cased crossing annulus, Hydrogen (H2) may be generated mainly from two sources, - One, from corrosion of the Service/ Casing pipeline, since Hydrogen is a byproduct of Corrosion. - Second, from the CP current outside the pipe especially in high water table areas. Over longer durations, this Hydrogen permeates through the steel pipe and gets trapped in the annulus. If the annulus is air sealed and not allowed to vent to atmosphere this Hydrogen can build up sufficient pressure to cause the carrier pipe or casing pipe to collapse. For casings with rubber end seals this is still a controllable issue as the rubber seals cannot hold high pressure and get blown out, still the effects of end seal removal will severely impact pipes in longer run. The main problem arises when the casing and carrier pipe are sealed at the end with Steel reducers welded to the carrier pipe as this leads to build up of trapped Hydrogen, that eventually lead to pipe failure. To avoid such cases vents are mandatory for releasing this Hydrogen (or leaked process gas) from the annulus between Casing and Carrier pipe. All this is in addition to the Hydrogen embrittlement of steel that anyways is detrimental!!

We recently performed some Medium Range EMAT Ultrasonic scans on insulated carbon steel pipe using the Innerspec Volta. The gear performed exceptionally well, pinpointing corrosion pits. If you have problems with corrosion under insulation (CUI) issues, or corrosion under pipe supports (CUPS), give Revo a call to discuss solutions. #ultrasonictesting #emat #corrosion #oilandgas #pipelineintegrity #assetmanagement #assetintegrity

Stress corrosion cracking (SCC) poses a significant threat to pipeline operators, as it results from corrosion-induced stresses leading to cracks in high-stress areas of the pipe. While sometimes visually apparent, SCC can be reliably detected using magnetic particle testing (MPI) and accurately assessed for depth using conventional shear wave or phased array ultrasonic testing (PAUT).   Addressing SCC typically involves either sleeving the affected area with compression or containment type sleeves, or, when safe, removing the cracked portion entirely through grinding.   To delve deeper into the subject or discuss your specific pipeline integrity concerns, don't hesitate to reach out and connect with Tilt. We're ready to provide expert insights and solutions tailored to your needs. #pipelineintegrity #scc #corrrosion #pipelineindustry #pipelineinspection #paut #mpi #oilandgas #ndt

Cathodic corrosion protection (CCP) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. There are two main types of cathodic protection: 1. Sacrificial Anode Cathodic Protection (SACP): In this method, a more reactive metal (anode) is attached to the metal structure to be protected (cathode). The anode corrodes instead of the protected metal. Common sacrificial anode materials include zinc, magnesium, and aluminum. 2. Impressed Current Cathodic Protection (ICCP): This method uses an external power source to provide a continuous direct current to the metal structure. The current flows from an inert anode to the protected metal, reducing its tendency to corrode. The anodes used in ICCP systems are usually made of materials like mixed metal oxides, platinum, or silicon iron, which are more resistant to corrosion. Cathodic protection is widely used in various applications, including pipelines, ship hulls, offshore platforms, underground storage tanks, and reinforced concrete structures. The primary goal is to prevent the metal from losing electrons (oxidation), which is the fundamental process of corrosion. #corrosionservices #corrosionengineer #cathodicprotection #cathodicprotectionengineer #cathodic_protection #cathodicprotectionsystem #cathodicprotectionequipment #CPspecialist #cathodicprotectiontraining #CPsystem #ICCP #corrosion #nace #cp #oilandgas #pipeline #cpequipment #cpmanufacturing #corrosion #corrosionprotection #corrosionprotectionengineer

Thermal Spray Aluminium Coating (TSA) is Metatech's best solution for corrosion in the challenging environments faced by oil and gas refineries. TSA offers protection against moisture, temperature fluctuations, salty environments, and more, making sure that your components stay in top condition for longer. What’s so special about our thermal spray aluminium coating? 1. Extended Service Life: TSA provides over 15 years of protection, which is 5–6 times longer than traditional paint systems. This means fewer shutdowns and less frequent maintenance, saving you time and money. 2. Superior Adhesion: It simply makes sure that the coating stays firmly in place, providing long-term protection. 3. High Corrosion Resistance: TSA is an expert in preventing corrosion, even in harsh environments. 4. Temperature Resistance: Can handle temperatures up to 500 °C. 5. Low Maintenance: With TSA, maintenance needs are minimal. 6. Instant Results: Unlike paint, TSA requires no drying or curing time, so you can get back to work faster. TSA is versatile and can be applied to various components and structures, including: - Subsea Pipelines - Offshore Platforms - Heat Exchangers - Vessels and tanks - Valves - Structures - Chimneys - Reactors For more information about Metatech Thermal Spray Pvt Ltd's Aluminium Coating, contact us today at www.thermalsprayworld.com #thermalspraying #coating #steelmanufacturing #cementmanufacturing #powergeneration #chemicalindustry

Cathodic protection is crucial because it controls the corrosion of metal surfaces, extending their lifespan. It's especially vital for infrastructure like pipelines, ship hulls, and offshore platforms, where corrosion can lead to significant safety and financial implications. Love the animation 👍🏼
