Thank you both friends and Happy New Year!

We are finisihing a tank farm, and we have discussed wether or not you have to use a tie-off after hand rails have been installed to get to the roofs for inspection. I haven´t found the information in OSHA or API, maybe it is in API 2220 but I don´t have it. Is it a must or not to wear them?

Hi, I am making a fast budget, does ab¿ny one know the aproximate price of a 60 hp, 300 psi, 430 cfm API pump?

Hi, does any standard recomend the time to check the plumbness of an API 650 tank? the contractor in our project insists that we do it early in the morning. Of course we rather do it just in after noon....

Thanks JStephen, you are right, it is said in section 1.1.1 that API 653 is for tanks that already had been in service.

When you are mounting a new tank, and you have to repair a weld in the body. Is the tank API 650 or API 653?

Thanks IFRs, I just convinced the contractor by looking at your thread that it´s the supervisor the one who decides the time to make the meassures. This tank has no floating roof but the look is not satisfactory.

We are also through the same matter, and if we measure in the morning the flatness of the shell is ok, but in the afternoon it doesn´t, the code does not say what time is recomended to do this, what would it be?

Hi How do you guys meassure flatness on the walls of an API 650 tank? ASTM A6/6M?

Hi What does it mean in NFPA standards when a chapter appears as "Reserved", and doesn´t have more information? Thank you
