seat tracks area usually are attacked by general corrosion and may be need some micron added layer, contact aircarft engineer for suitable specification.
what inhibitor type are suitable injected in gas transmission containing high CO2 & no H2S? What is multi injection and are there any effect?
--thx 4 ur advice--
thank you very much. is this similiar case with onshore gasline with the fluid content is wet gas, no H2S, no chloride? well gas Temp above 212deg F, so the duplex more suitable, isn't it?
where i can find composition (percentage) or component of pipeline construction cost? (for ex. pipe, valve, fitting, labor, paint, corosion protection, instrumentation, etc.)
thx for your advice
what is the suitable protective coating for external steel pipe with 95 celcius degree service temperature?
where i can find list of organic coating properties (ex. temperature resistance value of each coating material)?
thx for your advice
yes, we're considering to protect 20,000 meter external burried pipeline; the environment is soil (onshore) with 7000 ohm-cm resistivity and pH = 5.
For galvanic anode system, may be many anodes required to protect it, but untill what total current output of total anodes are considering to...
if we choose galvanic anode CP system for protecting old cs pipe, is there any max possible economical current output that is supplied by total anode than using ICCP system? What is other relevant considerations?
thx
