We Supply 5ct N80 Welding Casing Pipe in wide range of sizes

5ct N80 Welding Casing Pipe belongs to one of the many grades in the API 5CT specifications. There are four groups in this specification and the N80 grade belongs to group 1. The outside diameter of the pipes ranges from 1.315 inches to 13 3/8 inches. The API 5CT N80 Casing Tubing has different wall thicknesses according to the API 5CT standards. The N80 has phosphorus and sulfur in the composition. Due to the low alloying elements, the material is of low cost. Yet, the material has high abrasion resistance, corrosion resistance, impact resistance and strength.

Buy High Yield Strength API 5CT Grade N80 Tubing in various grades and size range

The API 5CT Gr. N80 Casing Tubing  has 552 MPa minimum yield strength and up to 689 MPa minimum tensile strength. The pipes are also marked with color bands to denote the grades. The N80 has two grades as N80-1, N80-Q. The N80-1 grade is marked with a bright red band and the N80-Q has a bright red band and a green band. The API 5CT Grade N80 Casing Tubing can have different lengths, diameters, wall thicknesses and dimensions. The tubing is used in applications other than oil field applications. The abrasion resistance and the strength enable the pipes to be used as clad pipes. The API 5CT N80q Tube is also used in the similar capacities.
