Sockolet Fitting

If you do, what are you going to do when the s**t hits the fan someone finds out?

Class 3000 is meets pressure rating for schedule 160 threaded fittings.

Class 6000 is needed for schedule 160 socket weld.

Do you have a set of "pipe classes" ( or pipe specifications) for the various systems in your plant ? If so, then the pressure rating (or class)of the elbow should be stated there.

Was all of the HRSG documentation discarded by the previous owner and is this your first job as an engineer ?

Since you will not tell us about the pressure/temperature conditions.... we cannot help you very much.

In the USA, the pressure/temperature ratings for various socket welded components (of selected materials) is contained in ASME/ANSI B16.11

Dear Sir,

design pressure 2120 psig and design temperature 984 deg F .

My pipe class is 2500.

If we see ASME 16.11 then it recommened the socket fitting Class 6000 for pipe schedule 160 and Class 3000 for pipe schedule XS and below.

We piping specification where the mistake happens and material brought out.

In normal case we follow ASME 16.11, so For pipe schedule Above XS we use #6000 rating for socketed fittings.

Could you help us regarding socketed fittings limitaions regarding pressure and temperature sustainability.

OK. If it calls for class 6000 fittings for that pressure/temperature/diameter then using class 3000 is just folly. Does that help?

Chau.....

According to my quick piping wall thickness calculation, in accordance with ASME B31.1 code, your systeml requires a wall thickness of 0.363 inches for 2"NPS A335P22 piping at 2200 psig and 1000F.

This includes a corrosion allowance of 0.0625 inches....which is reasonable.

Since Schedule 80 piping is only 0.218 wall thickness, the Sch 80 piping is unacceptable.

Since Schedule 80 piping is unacceptable, the 3000# fittings are unacceptable.......in accordance with the rules and logic of ASME B16.11.

Replace the 3000# fittings with 6000# fittings

Where are you located ?

Hi

I just want know the limit of voilation of code. As per code it is absolutely wrong.

i just want know the pressure temperature limit of sockolet fitting that can be voilate the code 16.11.

my query regarding the product of socket fitting limitation not the code specific.

is there some one know the testing of socket fittings and workability of these fittings.

please don't compare with code.

No, see below website's Non-shock Temperature Service Charts for P22.

Note, "Pressure-temperature ratings in the following charts are reported from ASME B16.11 - 1966 and are for historical reference only. As per latest revision of ASME B16.11, pipe fittings are rated based on the schedule number (wall thickness) of appropriate size seamless pipe of equivalent material..."
