Examples <strong>of</strong> Special Cases • Heavy Flanges (ANSI 1500#) – See Barrel Pump Example • High Temperature Pumps – See Barrel Pump Example • Sea Water Pumps (HDPE piping) – Expansion joints • Reciprocating Compressors – Cast cylinder heads; very low allowable loads – Hold down supports, snubbers • Steam Turbines • Screw Pump Example… – 10x8 Screw Pump – Flow = 198.95 m 3 /h, ΔP = 2255 kPa, HP = 300hp 36
