Power Plants) as per requirement of ASME Section-III NB

and meeting the requirement of Purchaser’s specifications.

This is to be established by a documentary evidence.

Clarifiation Required : Documentary Evidence may be

clarified in detail.

Documentary evidence like P.O, Manufacturing

63 21 General

Instead of HT of full header, it is proposed for local HT for

Dished end. Since thickness of feeder pipe is less than 19mm,

HT is not warranted as per section III NB, Table 4622.7(b).

Not acceptable.

64 22 GeneralIn case of repair after HT, it is proposed not to raise NCR, as it

is a weld deposit over weld.Tender condition shall prevail.

65 23 General

Whether the mentioned thichness of weld on weld joint for

outlet headers is bend side min. thickness or parent material

min. thickness after welding /repair, needs to be clarified.


66 24 General

The thickness in the bend region(after thining) of the feeder

pipes to be taken care such away that slight increase in

thickness of the pipe.which is very marginal leads to

NCR/DCR in all headers


67 25 General 20 NB thickness in bend region to be taken care Tender condition shall prevail.

68 26 General

NDE is 100% customer/third party witness is given in the

tender for all MPI,RT,UT,PT may be reduced in percentage

level.


69 27 General

Consider the feeder pipe thickness to avoid thickness built

up in weld joint after merging will reduce cycle time and

rework.

month

Photographs of the job cannot be provided due to security

reasons..Tender condition shall prevail.

71 2The manufacturer shall ….. will be borne by the
