Hi I am looking at finding a standard that could be used for design of an atmospheric process vessel (tank) for SG>1 toxic/corrosive products. The vessel diameter is 3m or less and will be supported on four legs.
I am looking at completing a flange design for a 2400mm square flue gas duct in a steel mill. Since it is not a circular flange type I can not use BPVC Section VIII Appendix 2 design criteria. Can any one shed light on if there is a design standard for such flange design?
Want to find out the best way to establish a stress intensity factor (SIF) for a butt weld join (BW) that was completed with a unfused root face about 1.6mm (1/16").
Can any body help with finding an isolation valve for a lime chip feeder duct attached to the kiln? Issue is to minimize trap air going into the kiln and the loss of vacuum in the kiln.

Hi,
I am after some information on a good engineering practice document that could be used for shipload out system piping system design for the transfer line between the Wharf and storage tank located inland. Any body know about a link to such information site? Or happy to communicate with me on...
Hi,
I am looking at issues with oxygen compressor building. Recently came a across thsi problem:
The issue is the comp building is naturally ventilated via the roof apex opening (600 wide runs along the building roof). The interstage PSV and discharge PSV tail piping vents within the building...

Currently I am reviewing the need for PWHT of anhydrous ammonia and ammine piping systems as a service requirement. Therefore I would greatly appreciate your feedback to following questions:
1. Is it the best industry practice to heat treat weld joints in anhydrous ammonia & ammine process pipe...
Hi,
Would like to communicate with other Urea plant engineers who have seen Intergranular corrosion (and weld pitting attack) problems related to Sandvik 2RE69 (25Cr/22Ni/2Mo Urea Grade Stainless Steel) austenitic SS material used as corrosion protection liner in High-pressure urea synthesis...
Hi, I work in a ammonia-urea plant and our NH3 stage is done in pressurised vessels. The vessels were design and fabricated to BS5500 in 1981 and have been in service since 1982. The vessels were manufactured using BS1501-224-32A-RT (with spherical dish heads) and all weld joints were post
