说明：
1、 表列“适用主管公称通径”为一般用途，如需用用于更小的主管尺寸，应与制造厂协商。
2、 表列E值适用于国际通用系列的钢管尺寸（英制管），如需用于国内沿用系列钢管（公制管）E值将有所调整，但L值不变。
3、 上表所列对焊支管台有STD、XS、XSS三种等级，选用较为复杂，为此，用户选用时，必须将主管及支管的公称通径及壁厚等级注明，本公司可根据上述参数确定符合用户需要的支管台等级及有关结构尺寸，如用于公制管，用户应注明主管及支管的外径和壁厚尺寸。
4、 定货时必注明主管及支管尺寸、压力等级及材料编号。如：WOL 14"×4" Sch40×STD 16Mn (用于英制管)
WOL 377×108 12×8 16Mn (用于公制管)
