The penstock pipe for the hydroelectric power plant is 2400mm in diameter and the thicness varies from 12mm to 30mm, total head ise 288mt. The pipe material was selected as St-52 (S355JR). As we had hard time to find the 26 and 30mm thickness pipe in the local market. We decide to switch to API...

Gentlemen, At our small geothermal power plant we have been trying to mitigate the metal silicate scaling occurring at the brine pipelines from the Wellhead Separator to the ORC Binary Power Plant. According to the initial calculations 6,6% of the NCG gas thrown from the top of the PP (96% of...

For instrumentation tubings and tubing connections I would recommend stainless steel material for better sealing at the threads within time.

Gentlemen, Thank you for the feedback, The 20" main line carries hot geothermal brine into an ORC Heat Exchanger. The tubings inside the Heat Exchanger are 1". Purpose of this 1" branch line is to simulate the scaling effect inside the tubings of the heat exchanger on a branch line tied to the...

Gentlemen, There is a 20" main pipe. The fluid velocity in the pipe is 1 mt/sec. Assume that we take a perpendicular 1" branch line from the main pipe, and then tie it back to the main line a few meters ahead. The material will be the same. Please see the attached link for simple scheme...

Gentlemen, Thank you very much for your comments. Dear Ed, The downhole temperature is 150 Cdeg. Do you recommend the thinnest wall tubing for economic reasons? Regards,

Gentlemen, We are drilling geothermal wells on a reservoir where the geothermal fluid is saline, has similar Na and Cl concentrations as seawater. Here, I am trying to select the proper material for coil capillary tubes which we use to inject anti scaling chemicals downhole. I have received...

Hi Kevin, Thank you very much one more time one more time. This is going to feed a binary plant, it needs to be large but how large is the question. Is there a general rule for this? Mufasa

Gentlemen, Thank you very much for your valuable input. This is for a new jeotermal power plant project in west coast of Turkiye. There are other JES Power plants in the country but they do not have such corrosive brine. They use carbon steel pipes with inhibitor system at the well. Thanks again,

Dear All, What kind of material would you suggest for a geothermal brine which has TDS (57000) and Cl (44140) concentrations? Ph of the brine is 7.5. On the other hand it is also rich in Ca, K and Mg. Well temperature is 174 Cdeg. Surface temperature is around 150 Cdeg. I have reviewed some...

Gentlemen, I already posted this thread at the Boiler and Pressure Vessels forum. I just saw that there is also a geothermal forum. For that reason excuse me for posting it twice. I am working as a project engineer at a Geothermal Power Plant Project. On the geothermal wellhead there will be a...

Gentlemen, API650 Appendix G - G.3.2 Aluminum Panels says as follows: "Attachment fasteners shall not penetrate both the panel and the flange of the structural member." Manufacturers are using either lapped joint or battened joint panel attachment system. At battened joint there is no...

Gentlemen, Our boiler specification is as follows: 350 ton/hour, 134 kg/cm2, 540 Cdeg, Single Drum, Natural Circulation, Top Supported, Oil Firing, C.E. Box Type We control our blowdown manually based on our daily lab results of the dissolved solids in boiler water. According to specification...

Appreciate your feedback, I will let you know about the outcome..Thanks for the steam forum tip too..

Gentlemen, I came across this thread, while I was doing a research on a similar case. In our boiler plant we would like to recover the HHS (High High Steam)condensate that is thrown out of the 3 steam traps located on HHS line at Steam Generating Plant area. HHS Steam Pressure is 84 kg/cm2 and...
