Spans indicated above shall not be used.2.+ Pipe walls require reinforcing at point of support.6.Tempratures in the above table are in degrees Celsius,as indicated (maximum 400 C)3.Allowable spans are based on a maximum bending stressof 41.37 Mpa (6000 PSI) or a maximum deflection7.Corrosion Allowance: As indicated, spans can be usedof 12.7 MM (0.5in)for lines of equivalent or smaller allowance than thosespecified in the above table.4.Hydrostatic testing: Spans are adequate without theaddition of auxiliary supports for insulated lines and8.All dimensions are in millimeters, except as noted.lines on shoes.
