API 5CT L80 steel Tubing

API 5CT L80 steel tubing mainly includes three types, such as L80-1, L80-9Cr and L80-13Cr. All of API 5CT L80 steel tubing can provide outstanding corrosion resistance. In addition, they all possess the yield strength of 552 to 655MPa and the tensile strength of above 655MPa, providing wonderful mechanical properties. The surface of our product is processed by heat treatment, which makes smooth appearance without any phenomenon like crease, hairline, separation, crack or scab. After the hydraulic test, hardness test and some others, our API 5CT L80 steel tubing can well ensure its sealing performance and impact resistance.

API 5CT L80 steel Tubing serves to transport both crude oil and natural gas from oil and gas layer to the surface pipeline after drilling is completed. It is able to bear the pressure produced by the exploitation process. After the outer surface is coated with a protective layer, the tubing is marked in accordance with the API 5CT standard and strapped with metal belt.

Our oilfield tubing & API 5CT L80 steel Tubing can be widely applicable to petroleum, construction, shipbuilding, smelting, aviation, electric power, food, and so on. This oilfield tubing can be classified as NUE type and EUE type. You can find here Casing Dimensions & Casing Wall Thickness.

Specifications include 1.9in (48.3mm), 2 3/8in (60.3mm), 2 7/8in(73.03mm), 3 1/2in(88.9mm), 4in(101.6mm), 4 1/2in(114.3mm) etc. The depth of our product for descending the well is basically identical to that of oil casing pipe. Both mechanical property and sealing performance of this tubing are also required to correspond with the oil casing pipe. Petroleum Tubing main steel grade includes J55, N80, C90, P110 and some others.
