Reinforcement Pad

Uhhh. Yes....

Is there a specific question here ? ..... Things work out soooo much better on these engineering fora when a specific question is asked rather than a declarative sentence.

That would depend upon the end Client's standards, which is not something this forum can advise on. A British Standard would not necessarily be an European Norm, nor would it be applicable west of the Atlantic, for example, yet successful and indemnity-covered installations can be found in all those locations.

The specifics are best discussed directly with the Engineer/Surveyor from the insurance company providing indemnity insurance and structural assurance warranty for the equipment in question.

actually, you're right . it should be designed according to the desired standard according to the customer's request. That's the problem. the customer requested the design according to the en 13445-3 standard. but that doesn't give an idea of the necessity of a standard reinforcement plate. It gives an idea whether it's appropriate or not if we just use it. and he leaves the use of the collar to me. The ASME and AWWA standards, by design, make you mandatory or say you don't need to. En 13445-3 has no equivalent. Not according to ASME and AWWa. I thought I'd ask my colleagues about it.

This is a public safety issue. The client's standards (or lack or inferiority thereof) should not be allowed to count, unless even more stringent.

you are right but, I am not boss of the company, I am a worker and I didnt sıgn the document, because, I cant do it. Its not safety for people so I tell them and didnt sign. I hope, maybe there was a one way for calculation , but there is no way for calcualtıo fo reinforcement plate in En 13445-3

ASME VIII Div 1 UG-37

It surprises me that EN-13445 would not have a standard and method for this, but if not, why not use the ASME method, which is quite rational, indeed obvious?

Because the customer wanted according to this standard and I could not explain to my manager that you may have ambiguities in the design according to this standard :) I said to do it many times according to ASME, my manager said No according to the customer wanted.

You still need to get on the blower to the insurance people, Mildred. Waiting for a better response here is just a waste of time. Get it straight from the horse's mouth instead.
