Each pipeline should be laid straight. When the case of the road around the bend or need other pipes, pipe segment curved straight pipe length should be less than the maximum allowable segment length. 3. Qu bend radius bend pipe of not less than 10m, bending angle should be as large as possible pipe center. With a length of tubing should not have reverse curvature (i.e., "S" shaped bend) bend a pipe or a bent portion of the central angle of less than 90 ° (i.e., "U" shaped bend).
