P——Flat end; S——Short round thread; L——Long round thread; B——Trapezoidal thread; E——Direct connection type.
aThe code is for reference when ordering.
bThe nominal weight per unit length (with thread and coupling) (column 2) shown is for reference only.
cMartensitic chromium steels (L80 9Cr and 13Cr) have a different density than carbon steels. Therefore, the weights shown are not exact values ​​for martensitic chromium steels. A weight correction factor of 0.989 may be used.
