·本表并未限制使用较薄或较厚壁厚的管子和管件。实际采用的管子公称壁厚可小于或大于本表所示的管子公称壁厚。采用较薄管子时。其强度可支配额定值；采用较厚管子时（例如对机械强度而言），管件的强度支配额定值。
·This table is nkt intended to restrict the use of pipes and fittings of thinner or thicker wall.Pipe actually used may be thinner or thicker in nominal wall than that shown in Table. When thinner pipe is used,its strength may govern the rating.When thincker pipe is
used(e.g,formechanical strength),the strength of the fitting governs the rating.
