Expand flare after insert the pipe expander. 051220**092/122** Diameter of pipe Dimension A (mm) 6.35mm (1/4î) A Liquid pipe 9.52mm (3/8î) 1.0~1.2 Gas pipe 12.7mm (1/2î) 15.88mm (5/8î) 1.4~2.2 Pipe expander Correct Incorrect Deflection Crack occurs Broken Incomplete Over outward (3) The maximum length and drop height of connecting pipe The maximum length is 20m The maximum drop height is 10m. To ensure the efficiency ,Pipes shall be as short as possible. Cautions for piping connection Do not twist or deform the connecting pipe. Do not mix dust. The bending radius shall be as large as possible. Both gas pipe and liquid pipe shall be heat insulated. No leakage in the flare. (4) Piping connection Connecting method Smear refrigerant oil on the joints of piping and flare. The bending radius shall be as large as possible. Align the pipe center when fastening, and tighten the nut, as shown in the figure. Pay attention to not mixing foreign matters into pipe such as sands.
