Does a conical venturi falls under ASME B31.1 or under ASME sect. VIII Div. 1

Thanks,

Is it common practice to do HIC testing on forgings? (In sour services)

Hi, The mill I used to work for the last 47 years produces horizontal fire tube boilers up to 1200 BHp (+/-50 MBTU) acc to Section IV limited by the welddetails of HW to 30 psi. We also made locomotive like fluidised bed heating boilers fired with wood pellets or coal also acc. to Sect. IV...

High, Isn't it practical to use staybolts at a pitch depending on the plate thickness?

LS. For wallthickness calculation acc ASME B31.1 304.1.2 2008 edition a Weld Joint Strength Reducion Factor W is to be used. In earlier editions p.e. 2002 there was no factor like this. 1st. Is that same factor still to be used in 2010 edition? 2nd. When a part of a system built to the 2002...

Thanks weldtek, LR will be involved as NoBo for required CE certification. Kwaliteitshenk

Thanks unclesyd, I'll try to contact one of the mentioned company's. Recently w've built deco's for Svitzer-Wijsmuller but they have no experience with PE envolvment.

Thanks unclesyd, When on board means, being present in the shop where the PVHO is to be built it's not possible to built an PVHO in Europe having an PE in Canada. Am I correct? Does anyone know the PE equivalent in the Netherlands? Kwaliteitshenk

PVHO last line of 1-5 says that a Registered Professional Engineer has to certify the Manufacturers Data Report for a PVHO. Is that the U-1A form from Section VIII-1 which is to be completed after hydrotesting etc.? Or is the complete design (drawing, calculations and material specifications)...

LS. ASME PVHO-1-2007 1-7.6 (a) says: "Penetrators shall be constructed of material suitable for the intended service and compatible with the vessel shell material" Still I have seen PVHO's (decompression chambers) made of SA516-60 plate with stainless steel penetrators welded in. Please advice

API 650 or 620? What is the wrigth design code for a hot water storage tank. API 650 or 620? Dia. app. 25 mtr. Cil. heigth 10-12 mrt. The water with max. temperature of 95°C (203°F) will be blanked with Nitrogen, overpressure of 30 mBar (0.45 PSi)to prevent corrosion. And is it allowed to...

For the leading tankbuilder of hot water storage tanks used in the agricultural in the Netherlands and nabor countrys it's common practice jacking tanks up to diameters of 30 mtr. It's not only cost saving but also safer working for the employers since the max level the have to do there welding...

LS. Does anyone know anything about the availability of acetyleendyssous and oxygen (to be used for flame cutting), Ar/Co2 shielding gas for GMAW and dieselfuel near Shanghai, China? And what the Voltage is and the alternation? Thanks in advance.

SJKWS, There is such a sequence in the Shell dep's (design engineering practice) You migth try to get a copy of the applicable part of it. Other oil company's will probebly have the same documents. Regards

No, I was only asked to quote a tank with seismic loads.

You're rigth JStephen it is a vertical tank. But just working trough the calculations is not so easy for an unexpierend person. Therefor I've posted it as a general question.

LS. What will be the effect on wallthickness etc when a horizontal storage vessel with a self supporting roof, slope 1:5 dia 81' cilindrical heigth 46' acc. API 650, has to be designed for seismic loads? (Loc. California) Thanks in advance.

We also are located in Europe, but we have to quote the delivery of pre-fabricated parts for a 3000 m^3 tank to be erected in the USA or Canada. Is it possible to send a copy of chapter 4 to adsl614059@tiscali.nl. (I'll buy the complete API 650 if it's an order)
