Good Day All, I've been trying to research the effects of having an undersized motor on a pump with some luck, but I would like a second opinion. Would the pump maximum flow/pressure capacity decrease? or would the motor run at a higher capacity but draw a lot more current (than practical) as a...

Hello All, So, I was informed that putting a wall mount heat exchanger that consists of a motor, pump, filter and a heat exchanger that runs at 8.5 gpm would cause cavitation of the pump, since the gearbox only holds 4 gallons of oil (plus the oil that would compensate for the volume of the new...

very good point, but what kind of testings can be carried out in order to determine the Matl? I know there's the sample one, where you grab a cube and send it to the lab, but what other methods are out there? Thank you

Happy Monday All, I need to asses the integrity of a 10 meter long 10 inch pipe (since it is a dead leg). However, after months of research, we have been unable to determine its origin (MATL). As a result, What would be the best method to determine the pipe's material and WT? are the any...

Thank you for your replies!

Hello, The Canadian company I am currently working for has all their piping Material as "grades" when looking back at ISO drawings. I am tasked with installing and purchasing two slip-on valves in order to replace the weld neck flanges (Grade 248, CatI) in the field. When i requested quotes...

Could someone please explain and define: 1. Above Grade Pipe 2. Below Grade Pipe Thank you, LeitoGM

Good Day Everyone, 2 simple questions: - What determines the hydro test pressure of a spool section? I keep ready 1.5 time the design pressure, could someone elaborate on that? - If there is a TOL fillet welded on the middle of the pipe, how would you carry on a hydro test? Thank you

Hi Snorgy, Thank you so much for replying to my thread at 11pm and I really appreciate your feedback! I will review Z662 and Z245.1 as you recommended. Cheers

Hi All, I am new in the piping design world, and I was asked to design a spool with a hydrotest package for a gas line operating at 1,200 psi at a north region in Canada. I choose the following materials for the spool: · The pipe can be a NPS 1 XS A-106 (WT 0.133 in) · A NPS 2: NPS 1 reducer...
