    Subsea Pipeline

    To calculate the methane leakage from a subsea pipeline between the SSIV (Subsea Isolation Valve) and the Riser SDV (Subsea Delivery Valve) with an empty inventory due to blowdown, you should first determine the leakage rate. Given that the passing rate is 124 kg/hr at the SSIV, despite it being...

    Position of Inert Gas or CO2 Line

    In a substation building, the main CO2 gas or inert gas header line is typically positioned above the HVAC duct. This arrangement helps ensure that any potential leaks from the gas header line do not interfere with the HVAC system and allows for proper ventilation and safety measures. For...

    Hi Engineers, I have a small quest

    Using hexane as a flushing media in HDPE piping systems is advantageous because it effectively dissolves and removes contaminants, particles, and residues from the pipe's interior. This helps maintain the purity of the conveyed fluids and ensures smooth operation. Hexane's solvent properties...

    very low temperature gasket maker (-100)

    For addressing a leakage in a low-temperature piping route around -100°C, choosing the right gasket maker is crucial. You should consider using gasket makers specifically designed for extreme temperatures. Silicone gasket makers can work well for a range of temperatures, including low ones, but...

    Antimony carbon vs Resin impregnated carbon

    Antimony carbon and resin impregnated carbon each have their own advantages and disadvantages. Antimony carbon offers good wear resistance and is often used in high-temperature applications due to its high thermal stability. However, it can be more brittle and less flexible compared to resin...

    IP68 Rubber Material

    For sealing to an IP68 standard rating, especially for a camera with electronic components used in a military environment, silicone rubber is typically the best choice. Silicone rubber provides excellent sealing performance, durability, and resistance to extreme temperatures, moisture, and...

    Pressure Increase

    In a sealed cryocontainer, the pressure of liquid CO2 or LN2 will not necessarily reach the vapor pressure at ambient temperature (e.g., 70 bar for CO2 at 20°C) due to the low temperatures maintained by the liquid. Even though the tank is uninsulated, the low temperature of the liquid helps keep...
