PRODUCT DETAILS
Product introduction
API 5CT K55 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 K55 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.
