Product Description

Seamless API 5CT Gr.L80 Steel Oil Casing Pipe

According to American Petroleum Institute Standard API SPEC 5CT, a specification for casing and tubing for petroleum and natural gas industries-used for wells, the steel oil casing pipe can be divided into ten types: H-40, J-55, K-55, N-80, C-75, L-80, C-90, C-95, P-110 and Q-125. Grade L80 casing tubing is an API 5CT oil casing pipe and is mostly used for oil well under sour (H2S) environments with varied end connections such as non-upset ends or an external upset end. L80 family includes L80-1, L80-9Cr, and L80-13Cr, is a group of pipe for corrosion-resistant casing application. Wiho metals is a leading API 5CT casing and tubing manufacturer and supplier, we provide not only a broad range of API 5CT L80 type 1, type 9Cr, and type 13Cr as well as their casing coupling, perforated pipe and more. Contact us for more details with the form below.

What's the difference between API 5CT L80-1, L80-9Cr and L80-13Cr?

API grade N80 -1 has the same Chemical composition as grade N80-Q, they both have the same yield strength, tensile strength, and elongation, their difference is mainly:* Heat treatments: API 5CT Grade N80 type 1 steel pipe is treated by normalizing and tempering and N80 type Q is treated by quenching and tempering. The collapsing strength and internal pressure strength of N80-Q are higher than that of N80-1 correspondingly.* API color code (bands): API 5CT N80-1 is a bright red band while N80-Q is a bright red band and a green band. The coupling of N80-1 is an entire red coupling and the N80-Q is an entire red coupling + a green band.
