Tubing is a kind of pipe that used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete. Tubing is made to withstand the pressure generated from the extraction process.
MTC is Mill Test Certificate, it contains all the specification of the steel pipe products. Including dimensions, sizes, weight, chemical composition, mechanical strength, heat treatment status, test result, traceability etc. These information is to make sure the quality of ordered steel products, tells the buyer what situations could be applied in engineering purposes. So the certificate standard for the MTC is generated, EN 10204 is European standard for the inspection documents for the steel products including steel line pipe, fittings, steel plate, valves, sucker rods etc. For certifying the results of the specific test is complied with client’s order.
OCTG Tubing in API 5CT mainly used to transport oil and gas well drilling and oil and gas. It includes oil drilling pipe, oil casing, pump tubing. Oil drill pipes are mainly used to connect drill collar and drill and pass drilling power. Oil casing is mainly used to support the borehole when drilling and after completion, to ensure that the conduct and completion of the drilling process after the normal operation of the entire oil wells. The pipeline mainly used in pumping oil and gas at the bottom transported to the ground.
a. Easy maintenance: line capacity is strong, simple in line.
b. High strength, trampling resistance, impact resistance, prevent short-circuit.
c. Sting threading pipe construction anti interference, signal shielding,to prevent the mutual interference between strong and weak electricity.
d. Safety: the safety of grounding and electric leakage protection appliances and timely.
e. Flame retardant: line to prevent burning when short circuit occurs.
f. Environmental protection: can be recycled, avoid secondary pollution.
g. High carrying capacity: under the condition of the same wire diameter passing rate is high; current circuit long life.
