Hello,
I wonder if what difference between chromium carbide applying for overlay of slurry piping and that of forming in stainless steel is or these two mean the same one.
I appreciate it if you someone replies on this.

Hello,
I was requested to come up with solution to prevent settlement of vertical in-line pump support due to ground heaving.
As reuslt of history of settlement pump supports have been down gradually.
I carried out piping stress analysis based on original design conditions but stress are...
Hello,
I am trying to conduct strss analysis on ethane liquid piping systems.
Design temperaure of this piping is ranged 150F to -200 F at 375psig and operation condtions was given -169F at 172psig.
This piping was constructed 20 years ago but supports rearragement are required due to...
Hello everyone,
I am trying to predict errosion-corrosion rate per year.
In order to do that I have to find Schmid number in its formular, Sc=µ?/d and then using the Berger and Hau correlation and rewriting to solve for K, K=(d/D)(0.0165)(Re)^0.86(Sc)^0.33
but I don't know how to calculate or...
Hello,
I am trying to predict erosion rate per year for slurry piping.
However, I am not sure if it is possilbe to use formula or otherwise there is any specific software available.
Could somebody please help me out?
Thank you.

Hello FK,
What is the handling fluid and what is design temperature?
For your reference, as internal materials F6(13Cr), which is 400 series stainless steel can be used as a minimun unless severe conditions.
Thank you for your comment.
As you mentioned specified Trim#2 can be replaced with Trim #10 in my old version of API602.
Then what kind of trim material can be recommned for replacement of Trim #10?
Regards,
Hello everyone,
We are making engineering spec.now but we want to know what in table 9 as per API 602 can Trim 10 (316SS) be substituted with?
I think that Trim #2 could be possible to replace it.
I appreciate it if somebody responds to my question.
Regards
The eventual intent of your client is to very that weldment would be obtained the same level of properties as that of base material through PWHT.
Accordingly, PWHT will increase to the resistance to brittle fracture due to hardness reduction and relaxing residual stresss on weldmetal.
For your...
Hello,
I am going to consider corrosion rate for mining slurry piping.
Does some one know the criteria how to detemine coarse slurry and fine slurry based on SFR.
As well, I wonder if all pipings as well as fittings have be overrayed due to corrosion- erosion matter in case of coarse slurry in...
Could you some one help me out how to determine a corrosion allowance for slurry piping/pipeline in oil sands mining process?
Generally speaking, I think that there are variables to do that, that is, size of solid, velocity, flow rate(min.& max.)and expected life time of pipe.
As well, I know...
Metengr,
This is a new slurry piping system not related to existing piping system.
I wonder if all piping materials, such as pipe and valve are included in MSD.
Thank you.
Hello,
I was asked to prepare material selection diagram for slurry piping system from owner.
Before doing this job I would like to know what information are required from our process engineer.
I wonder if a PFD is enough to prepare MSD.
As well, is there any particular format to prepared...
Hello metenger,
The delamination occurred in pipe is not weld metal but the surface of outside.
I can figure it out if this was happend in weld metal.
I am not sure but this problem could be related to heat treatment because the laminated area was covered when post-weld heat treatment on...
