Re: [MW:14942] RE: 14919] Stress relieving Rejected for 5 min less soaking time.

You can propose the following to your client:

            Perform Simulation on separate coupon, check the mechanical & metallurgical properties. If they meet the code requirements, it may be acceptable. After all, code is made by humans for humans.

2012/7/23 John Henning <jhenning@deltak.com>

Most common materials require 1 hour/25mm or 60minutes/25mm and I assume you are working with one of these materials.  Then, for a 40mm thick material the required minimum soak time is (40mm)*(60min.)/(25mm) = 96 minutes

 

You don't meet Code required minimum soak time.  Your soak time must exceed the minimum time.  Therefore, your pipe weld is unacceptable.  No discussion – it is clearly unacceptable in its present condition.

Dear expert,

 

As per ASME 8-1-UCS-56

 

We have done SR for our 40mm thk-30" pipe joint.

 

but unfortunetly, soaking time was just short by 5min.Now our client/PMC both are not agree to release.

 

Required time : 1hr.15min

Actual Time : 1hr.10min

 

It is acceptable OR could you share any technical view to convince client?

 

regards,

mohd.
