FW: [MW:17257] Re: ASME SA 333 Gr. 6 Chemical composition
Dear Azam,
I missed your email in the first place. Strictly as per Clause 5.2 of SA 333-2010 specification addition of these alloying elements are not permitted. However some of the alloying elements may come from the scrap used for steel melting.
What's the quantity involved? and what're the design requirements ?
A re-check of chemistry by OES spectroscopy would be advisable. If the results of OES conforms to the results of manufacture's "MTR", then material is to be discarded.
If the OES results do not pick up any of the alloying elements as indicated below, then it would be projects' discretion (i.e Client. EPC contractor and fabricator joint acceptance).
However talk to the mill in parallel and see if replacement is available , without jeopardizing manufacturing schedule.

5.2 When Grades 1, 6, or 10 are ordered under this specification (SA 333), supplying an alloy grade that specifically requires the addition of any element other than those listed for the ordered grade in Table 1 is not permitted. However, the addition of elements required for the deoxidation of the steel is permitted

it may vary as per location, (on/offshore), length of vent / drain point from tapping, closed drain, material spec

Re: [MW:17252] HPV & LPD pressure difference.
Dear Jawedji,
From the subject of fluid mechanics at lower level water pressure is very high due to water head created between upper level and lower level.it can be calculated as per given below:
Head loss=R*g*H
Where R=Density of fluid.
g=gravity.
H=head created between lower level and upper level.

Dear Jawed,
The pressure at LPD is higher and the difference is due to the pressure of the height of water column.
Regards,
Ranendra

6 in. (150 mm). The weld overlay cladding shall be
a minimum of 1
1⁄2 in. (38 mm) wide by approximately 6 in. (150 mm) long. For qualification on pipe, the pipe length shall be a minimum

As per B 31.3 seam to seam minimum distance is given as 4 times thickness but B 31.3 haven't mentioned L seam to L seam staggering. Means can be weld without staggering.
