API 5CT L80 casing and tubing are important materials in the petroleum industry and are available in a variety of grades, including L80-1, L80 9Cr and L80 13Cr. These pipes have a minimum tensile strength of 655 MPa and a yield strength ranging from 552 MPa to 655 MPa, making them a medium strength grade, similar to N80. L80 pipe is widely used in oil well construction, drilling and the oil and gas industry.

Product Introduction

API 5CT Grade L80 casing pipe is a type of steel pipe used in the oil and gas industry for casing in well construction.

During use, API 5ct Grade L80 Type 1 casing and tubing require heat treatment at specific tempering temperatures to avoid the material becoming brittle. In addition, cold working operations are not recommended for L80 grade pipes after heat treatment. For oil-quenched API 5CT casing, modifications can be made by adjusting the carbon content.

Under this specification, standard API 5CT L80 well casing contains no sulfur and is a non-corrosive component. Therefore, they have been widely used in the petroleum industry, providing reliable guarantee for oil and gas extraction and transportation.

Seamless API 5CT Gr.L80 Steel Oil Casing

API Specification 5CT is a technical standard for tubing and piping used in well systems in the oil and gas industry. Unlike API 5L, API 5CT L80 grade pipes are divided into three product specification levels, namely - PSL-1, PSL-2 and PSL-3. L80 grade pipes are heat treated after upsetting. According to this standard, the heat treatment process will be different for different grades.

For example, API 5ct Grade l80 Type 1 casing and tubing must not be tempered below 1150°F to avoid becoming brittle. In addition, cold working is not recommended after heat treatment of L80 grade pipes.
