API 5CT Q125 Casing 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.

API 5CT Q125 Casing 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.
