HX-4_Drawing.pdf

This is a technical engineering drawing and specification sheet for a plate heat exchanger model SR66LM manufactured by APV Companies Inc. The document contains detailed materials of construction specifications, including components such as the head (ASME B16.5 carbon steel), end support (ASME B16.5 carbon steel), tie support (carbon steel), titanium nozzles, and various internal components constructed from Series 316 stainless steel. The unit is designed to operate with water as both inlet and outlet fluids at specified temperatures and flow rates, with detailed dimensional tolerances and assembly instructions provided throughout the drawing.

The specification indicates the heat exchanger has a plate stack of 227 total plates with a frame size of 1" and is built to ASME Code Section VIII, Division 1 standards. Key operational parameters include a maximum operating temperature of 275°F, a maximum working pressure of 150 PSI, and dry machine weight of 254 lbs. The document references Work Order 26315 and includes APV's Seattle, Washington location, suggesting this is a commercial equipment specification for industrial heat transfer applications. Technical details include lift holes for installation, gasket seal tolerances, and provisions for metal-to-metal contact operation between plate surfaces when gasket sealing is not required.
