Thank you for your response, SMACNA recommends only H-16t for the duct dimension above 97'' and 10''WG.

Dear experts, We have an issue of duct opening at multiple places along the longitudinal and transverse joints in our site. After a preliminary study it was observed that the duct has been designed for a lower pressure class 3''WG where as required pressure is 10''WG. H-18t was used following...

Dear LittleInch, Thank you for your response. I am designing a cross flow heat ex-changer(HX) which transfer the heat from sodium to air, sodium on tube side and air on shell side. The heat removal capacity per HX is 20 MW. hence the air flow requirement is very high (80-110 m3/sec). But...

Dear All, I want to choose a blower/fan, for nearly 1,00000 cfm flow rate. I am searching for a compact blower for this flow rate and low static pressure requirement. Please suggest 1. Type of fan 2. type of blade etc, Considering low space and power...

We have a existing steel cabin(IS 2062) which is always kept at a 30 mbar gauge pressure. The size of tank is 3.5m*5m*5.5 m. It is already designed and erected at site with 6 mm plate thickness along with orthogonal stiffeners(ISMC 150 BOX) . During pressure test two bulged are observed on the...

Dear JAS and MJCronin, Thank you for this link. This system appears to be exactly what i am looking for.

Dear UofAGrad, We are using guard pipe concept in nuclear industry. To ease the leak detection in double walled system, compartment can be made with a nitrogen supply line which supply nitrogen at specified pressure.This allows you to detect a leak based on a drop in pressure. you can also...

hi! i need some help on design of non circular pressure vessel, specifically rectangular vessels with orthogonal stiffeners under external pressure. i have got some design rules from ASME Sec VIII, Div-1 appendix 13 , but there is no formula given for orthogonal stiffeners. can you guys...
