This product flyer is intended for reference purposes.  It should not be used in place of the advice from a licensed Professional Engineer.  Nominal pressure (PN) is based on C = 1,25 and an operating temperature of 20°C.  Weight is calculated using DN and Minimum wall plus 6% for use in estimating fluid flow. Actual ID will vary. When designing components to fit the pipe ID, refer to pipe dimensions and tolerances in the applicable pipe manufacturing specification.  To obtain pressure in psi, multiply bar by 14.5 (1 bar ≈ 14.5 psi).  Additional information is available at www.bingopipes.com.
