N——不加厚带螺纹和接箍；U——外加厚带螺纹和接箍；I——整体接头。

N = Non-upset threaded and coupled, U = External upset threaded and coupled, I = Integral joint.

a. 所示带螺纹和接箍的名义重量（第2~4栏）仅供参考。

Nominal linear masses, threads and coupling (col. 2~ 4) are shown for reference only.

b. 马氏体铬钢（L80 9Cr和13Cr）的密度不同于碳钢。因此，表中给出的重量对马氏体铬钢来说不是精确值。可采用重量校正系数0.989。

The densities of martensite chromium steels (L80 types 9Cr and 13Cr) are different from carbon steels. Therefore, the masses values shown above are not accurate to martensite chromium steels. A mass correction factor of 0,989 may be used.

c. 不加厚油管供货时带标准接箍或特殊倒角接箍。外加厚油管供货时带标准接箍、特殊倒角接箍或特殊间隙接箍。

   Non-upset tubing is available with regular couplings or special bevel couplings. External-upset tubing is available with regular, special-bevel, or special clearance couplings.

d. C90、T95和Q125钢级油管应按上表或订单所列的规格、重量和壁厚供货。

Grade C90、T95 and Q125 casing shall be furnished with sizes, masses and wall thickness shown above or on the purchase agreement.
