    VALID? 3/4 double block and bleed valve as a drain

    Hi Is it valid to use a 3/4 DOUBLE BLOCK AND BLEED BALL VALVE as a drain? (I mean, with one of the ends directed to the atmosphere. From what I've read, these valves are used where there is flow or in a instrument, not in drains) In which case one of these valves can be used in a drain...

    Use of low hydrogen electrodes according to API 650. Avoidable?

    Hi. I am part of a company hired to oversee tank construction by a contractor. API 650 states that low hydrogen electrodes should be used if plates are thicker than 12.5mm. First and second courses of the tanks are thicker (19 and 15mm). Courses are A36 Steel. We remind the contractor that...

    Radiographs in API 650 tank roof built to API620

    Hi. We are building a tank designed according to API 650 with 1,5psi internal pressure from nitrogen blanketing, except the roof, that is API620. The roof´s radius is 0,54D outside any type of roof considered in API 650, so is made according to API 620. Roof plates are 1/2 thick. Welds are full...

    Procedure for air test

    We have a 28m diameter new API 650 tank with a roof we need to air test. Considering the dangers of overpressure during the test, does anyone have a procedure for testing? One thing I know is that I could use a water syphon because of the low pressure involved. Thanks Carlos Molina from...

    A283 vs A36 in Tanks

    Hi. I´ve already looked for the response to this somewhat naive question in the forum. Speaking to the residente engineer, we realized that we don´t know why we use ASTM A283 Gr C plate instead of, say, A36, for Aboveground Storage Tanks for oil. We never use other than A283. If weldability...

    Internal Pipe corrosion

    We are doing maintenance to a 50000bls tank in Meta, Colombia. There is some pipe in the plant´s yard, that we could use. Incidentally, I came across a document on the web mentioning the maximun corrosion rate for pipe according to ASME, but didn´t mention the code. Which code adresses this? Thanks

    Hi. I was told in my Liquid penetrant course that surfaces should not be grinded prior to testing, cause that would cause litlle round indications to hide. Now i am working in the pipeline industry, and a quality control engineer with far more experience tells my, after I finish the LP test...
