How many factors we will consider when designing a SS filter housing?

What kind of information you are going to confirm with your client when you get inquiry for SS filter housings? As we know we need to confirm about the liquid source, application, working pressure, working temperature, flux rate, micron rating, material of filter housing first. Then we could come up with our design including details as numbers and size of the filter elements, housing cylinder diameter, micron rating, wall thickness, design pressure, closure type, Inlet/Outlet connection, surface finishing.

What factors will affect the cost of housings?

Housing cylinder diameter: the OD of the housing will be calculated automatically. And the OD will determine how many raw materials used for this housing production.

Wall thickness: similar with housing cylinder OD, will designed to meet the working pressure and flux rate. And the thickness of the raw materials also affects a lot for total cost.

Raw materials: for SS filter housings, we have different options available like SS304, SS316L, Carbon Steel, Duplex 2205, Titanium.
