API 5CT N80 Casing Tubing from China

Seamless tubing made from nonalloy steel, conforming to API 5CT specifications for N80 grade, used in oil and gas wells to line the borehole and protect against collapse. It falls under HTS 7306.29.60 as it is iron or nonalloy steel tubing specifically for drilling applications. The tubing's strength and corrosion resistance make it ideal for intermediate casing strings.
