PRODUCT
Corrosion resistant alloy (CRA) seamless pipe L80 (13Cr ) for API tubing and casing
OVERVIEW
It can be applied to oil and gas well production that contain carbon dioxide and chlorine ion acidic medium, meanwhile, since its high strength and excellent corrosion resistance and low temperature toughness, it is adapt to the high temperature and bad environment of carbon dioxide and small amount of hydrogen sulfide coexist.

DIMENSION TOLERANCE
The following tolerances apply to the outside diameter, D, of pipe
| Label 1 | Tolerance on outside diameter, D |
| < 4-1/2 | ± 0.79 mm (± 0.031 in) |
| ≥ 4-1/2 | -0.5 %D / +1.0 %D |
Wall thickness: tolerance for pipe –12.5 %
Inside diameter: inside diameter, d, is governed by the outside diameter and mass tolerances.
HOT EXTRUSION PROCESS

FEATURE OF EXTRUDED SEAMLESS TUBE
Extrusion pipe production is completely different from skew rolling and roller rolling and has following characteristics
(1) Compared with other methods of tube process, extrusion method is characteristic of the metal in the process of forming through three-way compressive stress, which can be used to produce low plasticity steel and alloy, such as zirconium alloy, titanium alloy, Ni-Cr-Fe heat resistant alloy, etc for application of atomic energy industry and special chemical industrial. And good surface quality could be obtained.
(2) Extrusion method has great flexibility and mobility due to the simple die, easy to manufacture and replace.
(3) The specification range of tube produced by extruder is larger than other process.
(4) Compared with other methods of tube process, extrusion can get better quality, the mechanical properties of tube are more even, and the inner and outer surface of the tube is better than that of rolling.
