1. API oil casing pipe / line pipe/oil pipe
2. Finish: black paint for this kind of steel pipe.
It can be bared, 3 layer PE coated for inner or outer, FBE for inner or outer , and EPOXY CARBOBITUMEN in order to corrosion prevention.
4.Packing: in bulk or with your detail requirements
Product Name | API 5L/5CT oil Casing pipe | |
Outer Diameter | 1/2-10” | |
Wall thickness | 0.8-12mm | |
Standard | ISO 11960:2004 | API Specification 5CT |
Weight Per Meter Plain End | 52.79lb/ft | 78,55kg/m |
Nominal Linear Mass T&C | 54.50lb/ft | 81.10kg/m |
Mass Gain Or Loss Due To End Finishing | 30.80lb | 13.97kg |
Type Of Pipe End Or Couplings | Casing Will Be Furnished Threaded And Coupled, 8-Round Short Thread (STC). | |
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 | |
