Notes :-

  1. The table is based on metric series of pipe dimensions given in ISO 161/1 on respect of pipe dimensions and ISO DIS 4422.

  2. The wall thickness of pipes is based on a safe working stress of 8.6 MPa at 27oC and the working pressure gets reduced at sustained higher temperatures. Occasional rise in temperatures as in summer season with concurrent corresponding reduction in temperature during nights has no deleterious effect on the working pressure of PVC pipes considering the total life of pipes. For class 1.2 and 3 of all sizes, this requirement need not be satisfied as the ratio of minimum wall thickness to nominal outside diameter does not exceed 0.035 in these cases.

  3. Mpa x 10 = KGF / CM2
