Hi Everyone, I thought twice about posting this as I'm not sure if it's in the spirit of this forum. I'm looking for a site that shows pictures of boiler and pressure vessels explosions. Preferrably with explanations to what happened and why. I've already Googled but had limited success...

Ok Rod. Thanks, Prabh

I need to replace the o-ring in my fuel petcock. The o-ring will be in contact with gasoline. I was wondering if I need to pay special attention to the material that the o-ring is made of for gasoline service? The o-ring is metric and approx. 7/16 od X 1/16 thick (don't have the actual metric...

Hi Rod, I was calling around and could not find the TB 1104 or I sure would have used it. I don't think that the valve cover sees a lot of pressure as there is a breather hose attached. This actually leads to another question, for which I should probably start another thread, but here goes. I...

Thanks Franz, I ended up using the Permatex Ultra Bond over the weekend. Everything seemed to go fine and I'll have to wait till I run the engine to see if the repair was successful.

I've got an oil leak where my valve cover of my motorcycle engine bolts onto the head. The local bike shop says they use 3-bond 1104 gasket sealer but all I can find is Permatex. I understand that they are both silicone gasket sealers that do not harden and are meant for high temperature...

Just my $0.02, John Britten designed a marvelous bike from scratch. He designed the whole machine including an advanced front suspension. If you search his name at the very least you'll see an amazing machine. Unfortunately he passed away a few years back.

Thanks to the both of you. I was incorrectly thinking that the hp conversion gave me the motor hp required to turn a chiller/compressor for a given "tons of refrigeration". I was using this logic against a household a/c unit and could see something wasn't right. Thanks again!

Hi MarauderX, Thanks for your response. I was at this website; http://www.engnetglobal.com/tips/convert.asp?catid=16 and I was converting 1 ton refrigeration (UK), I'm in Canada. When I use 1 ton refrigeration (US), I get 4.7hp per ton refrig as you mention in your response. However, I not...

I'm trying to find the unit conversion as mentioned above. Generally speaking the conversion was 12,000 btu/hr to 5.2 hp. There was also a boiler hp conversion that was really different. I think I should be using 1 ton refrig = 12,000 btu/hr = 5.2 hp. Can someone verify this and if you...

I need to do a thickness calculation on a dryer roll which was manufactured in the U.K. by Black and Clawson in 1975. The nameplate is stamped TS=35000psi. The material is BSS 1452 Class 17. Does anyone know if there is an ASME equivalent for this material? Thanks in advance.

Oops! Just re-read the previous posts and realized A 570 is an ASTM spec and not ASME. The coffeee hasn't started working yet. How do we edit a posting?

Hi Metengr, That's where I was going with my previous post. I just wanted to make sure that I had not overlooked the material in Sect. 2 Pt. D. I take it that the "A" designation ie. A 570, is not a material that I would find in Sect. 2 Pt. D and as such is not suitable for PV fabrication as...

Thanks for your response. Is A570 a material that is typically used in the fabrication of air receivers? If so can you tell me where to find it in Section 2 Part D. Thanks in advance.

Hi metengr, I was looking for SA516 Gr.70, thanks for your assistance. Sorry for posting the wrong spec.

Hi metengr, I'm trying to develop a table of plate thickness values (tmin)for air receivers. I was told the material was SA 570 Gr.B but I have not been able to locate it either. Based on your response I may have the incorrect material spec. I'll double check and post back. Thanks for...

I've been looking through Sect.11 Pt.D but can't seem to locate the stresses for ASME SA 570 Gr.B plate. Can someone point me in the right direction? Thanks!
