API 5CT L80

API 5CT L80

API 5CT L80 casing and tubing is a type of oil casing pipe that is mostly used in oil wells. API 5CT L80 has been frequently used in wells operating in sour (H2S) conditions and including a variety of end connections, including non-upset ends and an external upset end.

API 5CT L80 oilfield casing pipes are classified into three types: L80 type 1, L80 type 9Cr, and L80 type 13Cr. L80 type 1 is used in the presence of H2S, whereas L80 types 9Cr and 13Cr are used in CO2 application. TUSPIPE is a professional API 5CT casing and tubing manufacturer and supplier, offering API 5CT L80 oilfield casing pipe and API 5CT L80 tubing and casing coupling, perforated pipe, and other products.
