OCTG: Oil country tubular goods is the classification used for a variety of downhole products
API 5CT C90 Casing 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 C90 Casing Tubing can be widely applicable to petroleum, construction, shipbuilding, smelting, aviation, electric power, food, paper, chemical industry, medical equipment, boilers, heat exchangers, metallurgy 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. for more details check below Casing And Tubing Tables, Casing Grade Table, & Casing Data Tables.
