Determine the length of pipe

Determine the length of pipe (1) determined based on a fixed 8.2 piping path length of the tube measured in the field, to pay attention to the size of the radius of bending; (2) make access to the different types of pipe fittings of post taken into account; Jic hydraulic fittings(3) determine the length of the tube should be piecewise, cut, pre-assembled for easy on-site adjustments according to actual situation, if you cut off all at once, the accumulated error occurs when the piping on the difficult; (4) a short cut tubes need to try to take advantage of short tubes in various places, if necessary, can take a long straight pipe joints, but the pipe segment joints should not much less.
