What is the difference between U stamp and R stamp?
U and R stamps are ASME codes certification Stamps, qualifying organisations for the manufacture(ie fabrication) and repair and/or alteration of pressure vessels-in line with ASME boiler and pressure vessel codes(check ASME IX, ASMEViii Div 1). The U stamp is for fabrication of pressure vessels and the R stamp is for repair and/or alteration of pressure vessels. These are stamped on the finished work signifying complete compliance with the code requirements. (Contribution from Michael Obinna Okoye odu-Nigeria)
What is the difference between a U2 stamp and a U stamp?
An ASME U Vessel Stamp signifies that the vessel was made to the standards stated in Section VIII Division 1 by the American Society of Engineers. A U2 Vessel Stamp means it meets the standards for Section VIII Division 2 Alternative Rules.

State the assumptions made in the development of Euler's equations and trace the origin of these assumptions?
For incompressible flow the inviscid 1D Euler equations decouple to:ρt+ uρx=0px=0ut+ρet+ uex=0The 3D Euler equations are given by ρwρvρuρ ρuw ρuv ρu2 + p  ρu  ρv +  ρuv +  ρv2 + p  +  ρvw =0  ρw2 + p  ρvw ρuwρw(E + p)wz(E + p)vy(E + p)uxE twhere ρ is the density, u =(u, v, w) are the velocities, E is the total energy per unit volume and p is thepressure.

The assumption of incompressiblitygivesShow that in 3D the inviscid Euler equations with the assumption of incompressible flow decouple to:The mass conservation equation takes the form:=ρe+ ρ(u2 + v 2 + w2 )/2∇ · u =ux+ vy+ wz=0,ρt+ u · ∇ρ=0px=0ut+ u · ∇u+ρpyvt+ u · ∇v+=0ρpzwt + u · ∇w+=0ρet+ u · ∇e=00 =ρt+ ∇ · (ρu)=ρt+ ρ∇· u + u · ∇ρ=ρt+ u · ∇ρ=0 .The momentum equation along the x-axiscan be condensed into0 =(ρu)t+ (ρu2 )x + (ρuv)y+ (ρuw)z+ px=ρut+ uρt+ ρuux+ u(ρu)x+ ρvuy+ u(ρv)y+ ρwuz+ u(ρw)z+ px=ρut+ ρuux+ ρvuy+ ρwuz+ px+ (ρt+ (ρv)y+ (ρu)x+ (ρw)z)=ρut+ ρu· ∇u+ px+ (ρt+ ∇ · (ρu))⇒ ut+ u · ∇u+px=0.ρ1A similar argument reveals that the y- and z-axismomentum equations reduce to their appropriate equations,giving (in vector form):∇p(3)⇒ ut+ (u · ∇)u+=0.ρFinally, The energy equation can be manipulated in the following way:0 =Et+ ∇ · [(E + p)u]=Et+ ∇ · (Eu) + ∇ · (pu)=Et+ E∇ · u + u · ∇E + p∇· u + u · ∇p()()()111=ρ e + u · u + ρte + u · u + u · ∇ ρe+ ρ u · u + u · ∇p222t()()11=ρet+ ρu· ut+ ρte + u · u + u · ∇(ρe)+ u · ∇ ρ u · u + u · ∇p22()()11=ρet+ ρu· ut+ ρte + u · u + ρu· ∇e+ eu· ∇ρ+u · u u · ∇ρ+ ρu· (u · ∇u)+ u · ∇p22)()(∇p1=ρet+ ρu· ∇e+ e + u · u (ρt+ u · ∇ρ)+ ρu· ut+ u · ∇u+2ρ⇒ et+ u · ∇e=0 .
Does pig launcher require asme U stamp?
The pig launcher is a type of pipeline product. It requires an ASME U stamp in order to be properly certified.
Minimum requirement for ASME U stamp?
The design should conform to ASME Sec VIII Div.1.
What is the difference between ASME U and U1 stamps?
The ASME U stamp designates an unfired pressure vessel of more than 35 gallons (4.68 cu. ft.) has been built to ASME Code specifications, under ASME Code section 8. A U-1 form must be filed and signed by the authorized inspector for each and every pressure vessel built. The ASME U2 stamp is for unfired pressure vessels not built to ASME section 8 div. 1 standards, but under the alternative rules, has been inspected and found to comply with acceptable construction methods. A U-1 form signed by an authorized inspector must be filed for each such vessel, along with a description of the methods of construction used. The ASME U3 stamp is for high pressure (over 600 psi?) unfired pressure vessels. The ASME UM stamp is for pressure vessels less than 35 gallons capacity.

What are the main requirements of ASME U Stamp and what are it benefits?
Pressure vessels fabricated to ASME Sec VIII Div 1 need to be U stamped. The vendor's facilities should qualify for fabrication of such vessels and audited at periodic intervals as specified in the code. The benefits of fabricating to U stamp are 1) higher quality standards 2) competent authority involved in all stages for approval 3) uniformity of code requirements irrespective of geography
Does heater tubes in fired heaters require ASME stamp?
have seen one fired heater with asme u stamp. ASme recogbnises DF, direct firing however it excludes tube heaters per the follwoing form ASME VIII-1.U-1(c)(2) Based on the Committee's consideration, the following classes of vessels are not included in the scope of this Division; however, any pressure vessel which meets all the applicable requirements of this Division may be stamped with the Certification Mark with the U Designator:(a) those within the scope of other Sections;(b) fired process tubular heaters;(c) pressure containers which are integral parts

Is asme U-stamp U2 Stamp R stamp can get at a time?
normally U2 to be get after increasing the ability of manufacturers for pressure vessel (P<3000 psi) that have U stamp. but it is possible for U2 in same time normally U2 to be get after increasing the ability of manufacturers for pressure vessel (P<3000 psi) that have U stamp. but it is possible for U2 in same time normally U2 to be get after increasing the ability of manufacturers for pressure vessel (P<3000 psi) that have U stamp. but it is possible for U2 in same time
How do you get a u stamp?
you go to the post office.
How do you how create stamp in club penguin?
u cant
What are the production specifications of the plate heat exchanger?
It is manufactured according to the Electrical Business Law, High Pressure Gas Security Law, ASME "U" stamp and authorization certificate, and the domestic and international specifications of the first pressure vessel.YOJO already has rich heat transfer experience in the field of heat exchange equipment, if there are other related issues, we look forward to your consultation.
