Hi Experts,
I am faced with a problem of restoration of a Water tank, designed conforming to API 650, built in sand pad foundation. The tank is 48 m dia and 16 m height having cone roof supported by Shell.
The tank was ready for water filling when a bulge of the bottom plate was noticed...
Thanks BigInch and LittleInch for your suggestions.
The Fuel will be going through temporary strainers/ filters initially, by passing the permanent ones, during initial phase of commissioning. The Airport facility is having with filters before entering the 4 tanks of 10000 cu m. They are...
I am working on Jet fuel pipeline over 100 km long. The fuel will be supplied from refinery tanks to the airport tanks through booster and main line pumps feeding to the cross country pipeline.
The fuel recived will be cretified as per the newly introduced stringent JIG 1530 quality...
Dear Experts,
I am working on a lquid pipeline project (over 2100km long), which is having piping and pipeline going from UG to AG for locations such as below:
1. Pipe crossings at road crossings within the station. these include product pipes, fire water pipes and drain pipes.
2. At...
@BigInch , @littleinch, Thank you very much for your suggestions. This is liquid tarnsportation pipeline.
I summarise my understanding as below:
1. Code break can be at weld joint. I can use
2. All the valve station piping can be ASME B 31.4, Flange can be underground, though not...
I have a small 8" branch line from a 24" API 5L X 60, 9.53 wt pipeline at the block valve station for the valve by pass. The pipeline is over 100 km long, having 4 similar block valve stations. as the length is very short, I want to use 8"piping material, as I do not want to buy few meters...
Steve Jones, Thanks for the advice. Have you come across any internal corrosion protection for jet fuel tanks? Here the client is insisting to have. As you rightly said, the anodes will not work in traces of water. I am trying to convince the client that it is not required.
However, my...
I am designing a jet fuel tank. It requires internal cathodic protection as per the client.The tank is internal floating roof type, having an aluminium roof over the floating roof. The Interla CP is to prevent corrosion from the very unlikely occurance of water inside. Tank and the product is...
Power0020 and 7anoter4, thanke for your valuable opinion. I am taking up with the cable laying contractor to study the impact on the inductance effect on the pipeline for parrallelism and for crossings.
Thank one again.
Power0020, Thanks for the reply. The attached literature speakes about overhead power lines crossing pipelines ( both above ground and underground). In the case I am referring is interference of UG cable with a UG pipeline, crossing and also running parrelel for about 50 meters.
You have also...
Dear experts,
In one of our current projects, two 132 KV buried cable is proposed to be running parallel for about 50 meters to a16” buried pipeline with a gap of about 5 to 6 meters. These cables will be crossing the pipeline again after some distance, the cable will be the HT cable...

I agree with you that anchor block should be avoided as far as possible, and in all caeses of pipeline where I was involved there was no anchor block. My comment was not on the requirement of anchor block, but on the location, if at all is required, as the query was that the Op does not...

I have attended many tank situations like, long back when I was in charge of inpsection and maintenance of tank farms and pipelines.
The tanks properly designed could withstand two adjacent compartments having leaks.
There is no such load bearing capacity as scuch, as the roof is...
Eng180, Adding to what Big inch said above, I would like to add the following:
long distance transmission lines do haveundulating ground profile. pressure at any point is the sum of the static head, minus friction and correction with respect to the profile/ elevation. You have to add...
