Homogenizers - material of construction
Homogenizers - material of construction
(OP)
I am reviewing bids from four companies for homogenizers. The homogenizer block represents 1/3rd the cost of the homogenizer, and is obviously of great importance. Three bids indicate duplex stainless steels, either 2205 or 2507, as the material of construction. The other company uses just 316 grade stainless steel. The price for this company is half the others. The formulation we will start with has no chlorides and proceesing conditions are mild. However, I am concerned about just using 316.

I have experience with a 316SS homogenizer in a dairy application (ice cream). It has run for years and years with no major issues.
Without knowing more, that's all I got.
Good luck,

So, it would seem 316 ss is fine if we stick with a non-chloride formulation. The homogenizer cost is about half.

The company offering the lowest cost is from India. Frankly, their offer is so low, it is amazing to me.
RE: Homogenizers - material of construction
Ask the other two bidders why they do not quote 316ss. Nobody bids something expensive without a certain reason and I cannot imagine that the two expensive bidders cannot make a homogenizer out of 316ss. They might not meet the price of the Indian manufacturer but that is another story. You need a technical explanation.
