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...
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,
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...
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...
Dear All,
At the moment I am working on a project which is about modernisation of an existing 2100 mt cement pipeline that feeds the water treatment plant of our petrochemical complex with fresh water. We are going to replace the existing line with 1400 mm (t=12 mm) diameter steel pipe. In our...
There is an Equal Tee Configuration right on the discharge line of a Boiler Feed Water Pump. The Tee branch is very close to the pump discharge, less than half a meter. The piping and fitting material is Carbon Steel. Although it is Sch 160 material, there is severe abrasion. I plan to replace...
In our boiler plant the temperature of continuous blow water drained by steam drum is near 160 C degrees. We decided to pass this continuous blow water through the Make-up Water Tank via 4" SS pipe. Our objective was to cool down the continuous blow water and send it back to Demi Unit, besides...
In our boiler plant, there are two fuel-oil ( aboveground, flat bottom )storage tanks.
The tanks are around 14m in height and 10m in diameter. We will add an additive to fuel oil. In order to do this we are going to take an 8" branch from the existing line, this line will pass through an...

Next week I will be participating the tests of a centrifugal pump, which my company has ordered, at pump manufacturer's site. What would you expect at this type of test?
I am a mechanical engineer at a large petrochemical complex in Turkey. We are located on the seaside and we have decided to feed our fire water pipeline with sea water during an emergency such as lack of fresh water or very low fresh water pressure. In the project the suction line from sea to...
