Sir/s:
Thank you for the response.
It is a full cut out of joint. Because of not passing the NDE requirement.
As required by client, only 3 cut out on same joint.
Thank u
Hello everyone,
Hope you are all in good health.
I want to ask the experts, How many (multiple) times re-welding of joints is allowed in ASME? (CS, Alloy and Stainless Steel)
Thank you in advance for your answer.

Hello everyone,
It is our debate with our coworkers that PWHT is another kinds of NDT (non destructive testing).
As we know, PWHT will align microstructure of metal.
Can we consider PWHT as NDT testing of pipe?
Thank you
Sir,
would you help me interpret the drawing attached.
the meaning of PF?

Thank you Sir/s for your response.
ACI 351.2 for static equipment foundation is the Standard.
but I still coudnt found the required dimension/quantity of Steel pad prior to erection of equipment.
nevertheless, ACI standard would help me through.
Attached is the foundation drawing for...
The foundation is already there with Bolts..
our scope is to do the chipping of foundation, install pad, grouting and erection of equipment.
I just want to know, how to put the pad by following an international standard.
Where can i found the standard or rule of thumb stating the dimension of...
Respected Sirs,
I have search all the discussions, but unable to find the basic of foundation especially pad.
I want to learn the steel pad to be used for concrete foundation for Equipment such as vessel,
What standard to which i can see the pad distance between bolts?
I already have in hand...
Sorry for the wrong typo.

Sir/s:
Our project has mistakenly using 316 Stainless Steel instead of 304 Stainless Steel (Drawing BOM 304 SS).
Our client recommend to cut all joints and change to 304 SS Pipes.
As we know that 316L has higher corrosion resistant than 304.
What can we suggest to our client in terms of Code...
It was mistake using about the word "paint", actual we did is we sent the pipe spool 6" at galvanizing company for hot dip galvanizing.
The service for the pipe is for Service Air use for chemical processing plant.
The galvanizing company is weighing the spool thru weight bridge ( the trailer...
Good Day Everyone,
Could someone help me calculating the weight of pipe because the painting company is calculating the price through surface area of pipe and its weight and weight of the paint in microns.
Example Given are:
Pipe OD is 0.53 m2/Meter
Pipe Thickness is 7.11 MM
Pipe Weight 28.83...
Thanks for the reply.
It is a longitudinal crack.
and have a 10degree C preheat.
Is there any factory defect can be considered also in determining the cause of the crack?

The crack is actually not on weld but on pipe horizontal formation (or going to the length of pipe) almost 2 inches in length. the crack is in the middle between two welded joints.
the length between two joints is approx 15mm.
Thanks in advance
