thanks for your response guys
As additional information, because the amount of piping system is very much then if the piping test alone, amounted to more than 1000 packages. If some test piping package with vessel as a system, it can be reduced in number.
Also, because the design pressure is...
Hi guys,
My company currently have a project, Ammonia Urea Plant Project.
The contractor is preparing the hydrotest plan for piping system, he would like to carry out the hydrotest of piping system together with the connected static equipment to expedite the progress, which s allowed by the...
many thanks weldstan, Duwe6, MJCronin to your advise and valueable information. Ammonia stored is anhydrous at temperature -33C. The tank is double wall, diameter of inner shell 40250 mm and outer shell 41750 mm. Annular space filled with perlite insulation. We have existing 4 ammonia tanks...
thanks gentlemen, in my consideration is the technical design of the ammonia storage tank follows API 620, while the phased array method has not been accommodated in API 620 (please correct me if I wrong). Therefore, technically, can I use PA method to replace RT method?
Hi Dear, as per Code, whether phased arrays test method could be used for ammonia storage tank to replace radiographic test? What are the things that must be considered to make phased arrays test. Many Thanks
Dear metengr & weldstan, scope of Appendix G.3 is the corrosion because of presence of hydrogen sulfide in the service condition, isn't it?. In the existing ammonia storage tank (I have 3 exisiting tanks) we inspect every 5 years, no corrosion problem I found. Normally liquid and vapour ammonia...
For ammonia (NH3) storage tank (plate material of A537 Cl.1) of capacity 20.000 MT, is it a must to apply API 620 appendix G (G.3) Hydrogen Induced Cracking ??
Which material is the best for pump to handle Ammoniated phosacid liquid, HA 28.5 : 654 SMO : HV 9
Ammoniated phosacid : 28-48% P2O5 - N/P :0.1-0.l42 - 10% solids - 5% H2SO4 (MAX). Traces Cl- , F
HA 28.5 : 26-28 % Cr : 5-7 % Ni : 3-4 % Mo : 0.03-0.46 % C
654 SMO : 24 % Cr : 22 % Ni : 7.3 %...
I have some questions here.
1. In ammonia line ( dia 4", 6" ), is it recommended to use socket welding joint ?
2. What about inspection & test procedure ?

I have some questions here.
1. I need an ammonia pump (vertical can type) with specification : capacity 30 m3/h, total head 13.5 kg/cm2,
and NPSH A. = 0.4 m. Is it possible to get a pump with dia. Of barrel < 700 mm and distance between
center line of suction nozzle and bottom of barrel < 1700...
