Hi racookpe1978, It is a gravity pressure in soil...

Hi metengr, Originally, the pipe has a bell and spigot joint. Then, it has been shorten the length as required at site installation. Then, the proposed solution is to join the pieces by butt welding.

Can anybody explain if butt welding for ductile iron material is applicable? What parameter required to obtain good sound weld? Thanks.

Hi, May I know where can I find in ASME B31.3 the minimum longitudinal weld seam distance for piping and what should be their locations? Thanks

I would like to know how to join the Copper-Zinc-Lead material? Which is better process, GTAW welding or Brazing? And what filler I have to use?

I would like to know the minimum hardness test value requirement of P11 weld joint? As mentioned in the ASME standard is the maximum value only..

Kindly tell me what is the ASTM/ASME equivalent for U71Mn material. And what electrode I can use for overlay welding? thanks.

Well folks, I found the answer from the previous thread..see the link below: http://www.eng-tips.com/viewthread.cfm?qid=43256

Ron, i appreciate your concern. I am familiar in hydrostatic testing but of course I am not familiar in special case like this. If I will ask some local consultant, I think I don't need to raise this question in this forum. The reason I need the calculation is because we need to fabricate blind...

Kindly give me a calculation of plate thickness to be used for hydrostatic test..

Hi QualityAsia, If I can only convince TPI that paragraph QW-200.4(b) shall not be considered, I will be happy. But the code must be followed for combination of welding procedure..as per the requirement according to QW-451.1.

Hi Weldtek, According to ASMEIX...To prepare single WPS with multiple PQRs, refer to QW-451.1, Note (2) "For combination of welding procedure, see QW-200.4". Where in QW-200.4(a) for qualification of WPS for root pass deposit only, refer to QW-200.4(b). In QW-200.4(b) to support the single...

I am also little bit confused with the interpretation...why ASME IX provides an example like in par. QW-200.2(f), where mentioned about "a single WPS may cover 1.5 to 32mm if PQRs exist for both the 1.5mm through 5mm and 5mm through 32mm thickness range". How we can satisfy the paragraph...

Hi Everybody, Where can i find in ASME standards the minimum girth butt joint to girth butt joint distance for piping?

Hi Everybody, This is my query: I would like to prepare single WPS with two supporting PQRs. PQR-1 is GTAW process with 2.77mm coupon thickness and PQR-2 is SMAW process with 10.00mm coupon thickness. I would like to know if I can make WPS with the PQR-1 as root/hot pass and PQR-2 is fill/cap...

I would like to know where can I find the required maximum hardness test value(HB) of carbon steel(A106-B) after post weld heat treatment. Is this mandatory to carry-out in the preparation of welding procedure, if the design codes are for ASME I, B31.1 and B31.3?

ok, thanks metengr..

Where can I find in ASME Section I the requirements for the heating and cooling rate during post weld heat treatment of material(ie: Carbon steel)?

It was our customer who made the design. Anyway, I will consult to the welding engineer for this. Thanks.

It is to vent the gas from a condensate water in the condenser.
