Can anyone give me any insight into the Brinell Hardness requirements for Monel 400 after PWHT for pipe? Is it in the range of 160-185 BHN? I also can not find any information regarding at what hardness levels does Monel 400 become susceptible to cracking. I have seen some documentation...
Can anyone explain why the allowable stresses for F316 are higher than F316L in SA-182? It appears that above 850'F, 316L is not suitable wheras 316 has allowable stress up to 1500'F.Other than the low carbon content in the L grade, I see no difference in the composition.
I've seen that a copper based thread lubricant is not recommended for use in HF alkylation units, rather a Nickel base anti seize compound is recommended. Why is that? I've heard that for marine applications to prevent a galvanic cell from forming but not HF units.Thanks

We have a Delaval barrel type Recycle Gas compressor in our Reformer unit.Periodically the compressor becomes fouled with ammonia chlorides, which produces high rotor unbalance vibrations.Consequently, we have to take the compressor out of service and purge it to the atmosphere.By purging I...
Hello everyone,
First time I've posted an inquiry here although I've used it as a reference in the past. I have a double suction impeller with a shrink fitted wear ring that experienced a fatigue failure.I want to calculate the stresses on both the impeller hub and ring(both tangential and...
