HX drawing for F37.pdf

This is a technical drawing and specification document for a horizontal heat exchanger manufactured by ChemTed LLC, located in Rio Vista, Texas. The document contains detailed engineering specifications, material of construction details, design parameters, and manufacturing requirements for a shell-and-tube heat exchanger unit.

The exchanger is designed for a maximum allowable working pressure of 300 psig on the shell side and 150 psig on the tube side, with design temperatures of 400°F for the shell and 350°F for the tube side. The unit features stainless steel construction for key components including the shell, channels, nozzles, and flanges, with carbon steel materials used for other structural elements. Construction specifications include comprehensive tolerances, weld details, hydrostatic testing requirements at 450 psig, and surface preparation and coating requirements using Sherwin-Williams MacroPoxy products. The document specifies a capacity of approximately 5.8 million BTU/hour for medium liquid water flow conditions, with detailed dimensional drawings, bill of materials, loading calculations for fixed and sliding saddle supports, and nozzle schedule information. The exchanger is marked "Release for Fabrication" and includes revision history documenting design approvals and modifications during the product development and quality improvement process.
