Downcomer Piping Sourcing and Holding for Witness
Downcomer Piping Sourcing and Holding for Witness
(OP)
Can you guys give some hints on following Qs in regard to CFB Downcomer Piping Sourcing and Holding for Witness?
Q1:
We're sourcing Downcomer piping for two CFBs: 1) 56T (169m 558mm OD x 25.02MW) SEAMLESS Carbon SA106C, random length; 2) 53T (195m 457mm x 25.7MW)SEAMLESS Carbon SA106C, random length. The qty here is for one CFB. Term of delivery:CIF Tianjin or Shanghai, China by Feb 2006.
As the qty is small and most of mills around the world are fully booked, we've located "Valcovny trub Chomutov a.s." of Czech Republic as a potential vendor.
My question is: does anybody know if there is still another optional vendor/manufacturer other than "Chomutov" that can meet our request? if not, is there anybody who has experiences dealing with "Chomutov" since we have no idea of how good this mill is?
Q2:
As we're not sure about Chomutov qualification, which critical witness points have to be included in PO?
Looking forward to you guys' valuable advice.
Thanks.

The cost of a trip to audit their facility is small dollars in comparison to the end result. I have done many of these types of audits and nothing beats having a look see at the facility that will supply your piping.

The most critical parts of the audit are their lot control (traceability) and heattreatments.
