Mass (weight) determination	a)     We will response for weighing the pipe to determine conformance with mass tolerance. b)    Threaded-and-coupled pipe may be weighed with the couplings screwed, provided proper allowance is made for the mass of the couplings. c)     Threaded-and-coupled pipe shipped without couplings will be weighed with thread protectors if proper allowances are made for the mass of the thread protectors. But weighing of a pipe is not mandatory. d)    Each length of casing will be weighed separately
Mass	a)     The masses determined as described above will conform to the calculated masses as specified herein(or adjusted calculated masses) for the end-finish specified on the purchase agreement, within the tolerances stipulated in next blank. b)    Calculated masses shall be determined in accordance with               Ml = (Mpe *L) + em Where (1)        Ml is the calculated mass of a piece of pipe of length L, in kilograms (pounds); (2)        Mpe is the plain-end mass, in kilograms per meter(pounds per foot); (3)        L is the length of pipe, including end-finish, in metres (feet), (4)        em is the mass gain or loss due to end-finishing, in kilograms (pounds),Here it equals to 13.97kg or 30.80lb.
Tolerance Of Weight	a)       Each Pipe -3.5%~~+6.5 tolerance will be allowed b)      Total Weight -1.75 will be allowed
Tolerance Of Outer Diameter	-0.5%D~~+1%D
Threading	Pipe threads, gauging practice and thread inspection conforms to the requirements of API Spec 5B. Pipe ends shall not be rounded out by hammering to secure conformance with threading requirements.
Workmanship of ends	a)      The inside and outside edges of the ends of all pipe will be free of burrs. b)    The threads have shown a tendency toward adhesive wear, or galling during make-up and breakout. But their galling resistance may be improved by surface preparations
