Composite Overwrapped Pressure Vessel (carbon fiber)

FRP composite material is a high-performance material formed by mixing fiber material and matrix material in a certain proportion. It has the characteristics of light weight and hardness, non-conductive, high mechanical strength, less recycling, corrosion resistance, etc. In addition to the conventional copper foil FRP winding tube and high-voltage insulation tube, the high-performance functional FRP tube produced by the expansion project can also be used in 5G antenna covers, special bracket shells for wind turbines, special lithium battery jackets for oil exploration, wind power couplings, high-voltage drop-out fuse tubes, etc. The tube diameter is between 100mm and 800mm, the wall thickness is between 5mm and 50mm, the length is between 0.4m and 7m, and the single piece weight is between 5kg and 400kg. About 2,800t/a of the products need to be painted, and the rest of the products do not need to be painted. #ABSCORES #FRPCORES #plasticcores #plastictube #PECORES

Nice job Etheridge Pipeline & Conduit! Inserting the hand hole is a great idea and makes it more accessible and noticeable. Another top tip is to add a tracer wire to make the fiber line more locatable in the future. It's amazing how simple improvements can add up and protect our #utilities #damageprevention #fiber #locates #pipeline #CBYD Utilocate

Cathodic protection is crucial for safeguarding buried pipelines, commonly those with diameters ranging from 8 to 20 inches, against corrosion. Two primary methods are commonly employed: sacrificial anode systems (using magnesium anodes) and impressed current systems. Magnesium anodes are frequently used for smaller diameter pipelines or areas with low soil resistivity. These anodes are buried at regular intervals along the pipeline and connected electrically to the pipe. Magnesium, being more electrochemically active than steel, corrodes in place of the pipeline, providing protection by sacrificing itself over time. This method is simple and effective for relatively short pipelines or those in favorable conditions. For larger pipelines or environments where magnesium anodes alone may not be sufficient, an impressed current system can be implemented. This system involves placing inert anodes, powered by a direct current source, along the pipeline. The current pushes electrons towards the pipeline, preventing corrosion by ensuring the steel pipe remains cathodic to the anodes. In addition to cathodic protection, buried pipelines are often coated with protective layers such as Resistance Thermosetting Resin (RTR). RTR provides a durable barrier against soil chemicals and moisture, significantly reducing corrosion potential. When combined with cathodic protection, the paint ensures that the protective system works more efficiently and requires less maintenance. This dual approach of using magnesium anodes and impressed current, alongside a robust protective coating like RTR, is essential for prolonging the lifespan of buried pipelines and maintaining the integrity of vital infrastructure. #buried #pipeline #impressed #current #rtr #magnesiusm #steel #pipe #cathodicprotection #paint

Thermal Integrity Profiling (TIP) Thermal Integrity Profiling (TIP™) is a technology that utilizes the heat generated by curing of concrete to assess the integrity and quality of drilled shafts, augered cast in place (ACIP), micropiles and other concrete foundations. From the test results, necks, bulges, the as-built shape of the shaft, and variations in concrete cover and including steel cage eccentricities, can be characterized. #GRLEngineers #TIP
