METHOD OF ASSEMBLING UNITS OF SPRINKLER OR WATER RECEIVER OF WATER COOLING TOWERS Russian patent published in 1997 - IPC

FIELD: heat and mass-exchange technics. SUBSTANCE: according to invention, members of units and spacers on tightening pipes or rods are fastened by way of contact heating of pipe or rod ends to a temperature by 20-50 C exceeding that of fusion of pipe and rod material. As a result, a collar is formed. Then ends are cooled to ambient temperature by means of calibrating attachment. Tightening pipes and rods have axial opening in their ends made of polymer material. Ratio of inner diameter to thickness of walls of tightening pipes or rods is 2 to 5. EFFECT: improved assembly procedure. 4 dwg
