Potential Causes for cracks in Suction Liner in Slurry Pumps?

[billions]

Looking at very large slurry pumps with a high chrome white iron suction liner. We're seeing some very large cracks in the inside/hole/inlet of the suction liner.

Could be many things like, over or under torqued bolts, rapid heating (really cold here), dropped it, large nose gap (more turbulence).

What else could it be?

I'm trying to investigate, so any recommendations/insights would be cool.

As for the liner material, read a paper that showed tungsten and another variation of it to be highly durable in impact and sliding wear applications specifically for slurry like this.

Also, the company has materials engineers looking at the appropriate lines over the last yr or so as well, so I'm sure they know what they're doing too
