316L Stainless Steel Construction
The B9MP-R400 is manufactured from 316L stainless steel, a corrosion-resistant material commonly used in hygienic and process piping systems.
Compared with standard 304 stainless steel, 316L provides improved resistance in many environments involving chlorides, cleaning chemicals, and demanding process conditions.
Material compatibility should always be confirmed for the actual process fluid, cleaning chemistry, temperature, sanitation method, and operating environment.
Clamp Cross Configuration
The clamp-cross design provides four sanitary clamp connections arranged at right angles around a common center point.
This allows one process line to divide into multiple branches or several lines to converge at a common connection point, depending on system design and permitted flow direction.
Each branch uses a removable clamp connection, which can simplify equipment installation, cleaning, inspection, and piping maintenance.

Installation
Confirm that the 4" tube O.D. and 316L stainless steel material match the rest of the process system before installation.
Inspect all clamp faces for damage, contamination, dents, or scratches that could interfere with gasket sealing.
Use compatible sanitary gaskets and clamps on each of the four connections. Gasket material should be selected according to the process fluid, operating temperature, cleaning chemicals, and sanitation requirements.
Align all piping properly before tightening clamp connections. The fitting should not be used to pull misaligned piping into position or carry unsupported piping loads.
After installation, inspect the completed joints and verify leak-free operation under appropriate system conditions.
