Insights on technology, productivity, programming, and good reads.
The differences have to be taken into consideration by both designer and welder. The high thermal expansionand low thermal conductivity of the austenitic steels lead to higher shrinkage stresses in the weld thanwhen carbon and ferritic steels are used. Thin sections of austenitic steels may therefore be deformed when an abnormally high heat input is […]
In pressure Part Industry we use various type of material. Typically in industry like this, we mainly classify material as Mild Steel also known as Carbon Steel, we also use low & high alloy steel & yes stainless steel! What diffrentiate staineless steel from Carbon steel is its corrosion resistance properties, whcih comes because of […]
Hello friends, After long time I’m updating my blog.Please find here some shortcut to useful websites.http://www.cleavebooks.co.uk/scol/ccpress.htm For Conversionhttp://www.unitconversion.org/ for Conversionhttp://mrnathan.munichre.com/ For World Sesmic/Wind Chart!http://www.nicee.org/IITK-GSDMA_Codes.php Great india IIT website for earthquake and wind load calculationshttp://www.allstainlessltd.co.uk/otherproducts.asp Good site for pipe fittings details I’ll update more links soon..
On 1st May I joined Ziemann, My Previous company is Boilers and my new company is in Brewing. and Now my job profile has changed.. Now i’ll learn how to make beer.. As i’m learnign I’ll share some good thing in steam with you after a while Till then take care..
Lets start this session with some overview on Control Valves. A power operated device, which modifies the fluid flow rate in a process control system. It consists of a valve connected to an actuator mechanism that is capable of changing the position of a flow controlling element in the valve in response to a signal […]
Most of the cases.. Custumer ask for expected boiler life & we tend to say approx 10 years.. How one arrive at this figure? I’ve asked this question so many time to may expert inthis field but not able to get any satisfactory answer. Recently i went thru ASME VIII Division1 , where the Fatigue […]
OK..Now the big question.. the flow parameter Re & thermal parameter Pr, how they connects to HEAT TRANSFER??? So for our help.. Mr. Nusselt has created Nusselt Number!! The traditional dimensionless form Nusselt number Nu, which may be defined as the ratio of convection heat transfer to fluid conduction heat transfer under the same conditions. […]
Lets See.. “CONVECTION HEAT TRANSFER” Heat transfer occur when there is Delta T Across the two bodies.. heat always flow from hot side to cold side. Heat transfer may occur under natural draft or under forced circulation. Industrial heat transfer equipment are mostly occur under forced condition. As discussed above, one can conclude that the […]
The discussion is IS 4503 Oriented. IS 4503 is the code for heat exchanger .. Type of heat exchanger Fixed Tube Plate U Tube Floating head Classification on Pressure 2.5 kg/cm²(g) 6.3 kg/cm²(g) 10 kg/cm²(g) 16 kg/cm²(g) 25 kg/cm²(g) 40 kg/cm²(g) Classification on Temperature Max. Allowable Metal Temperature Carbon Steel : 250ºC SS : 120ºC […]
In day to day life we have to deal with Pressure vessel / heat exchanger manufacturing code.These codes are not performance oriented code, these are safety oriented code. The basic approach of the code is from user point of view.. more the hazard stringent will be the code. The Category of the pressure vessel are […]
