3 02/18 special structural elements will be provided by the Design Engineer. The design provided by Thermal Pipe Systems, Inc. and their engineers for the piping will be in accordance with ANSI B31.1 and good engineering practices. Fluid flow design will be based on Hazen-Williams formula with "C" Factor of 150, or a variation of the Euler formula for water flow. INSULATION: Thickness of insulation for VEE-TITE pipe and fittings shall be as shown on page four. TEMPERATURE AND PRESSURE: The VEE-TITE piping system and all its components are designed to operate up to 150 psig at 230oF plus typical surges. DIMENSIONS AND WEIGHTS of insulated VEE-TITE piping are as shown on page four. The VEE-TITE piping will be furnished in 20-foot lengths.
