Corten A 09CUPCRNI A


Corten steel also known as Corten steel, divided into two categories: Corten A, CortenB, is the representative of the cu-p series steel in the United States, belongs to low alloy high strength atmospheric corrosion resistance structural steel, called weathering steel in China.

It is mainly used for

Economized gas, air preheater, heat exchanger and evaporator in high sulfur flue gas are used to resist condensation corrosion of sulfur flue gas.Excellent resistance to sulfur ions, hydrochloric acid and other acid corrosion.Spiral groove tube is a high efficiency, economic, mature heat transfer element, has been widely used in a variety of boiler air preheater products.The helical groove tube USES the inner wall of the lotus root joint and the helical groove to conduct the flow, so as to forcibly disturb the working medium inside the tube, thus improving the heat transfer efficiency.The heat transfer coefficient of spiral grooved tube can reach 1.25 times that of light tube of the same diameter. The use of spiral grooved tube can improve the efficiency of heat exchange equipment, reduce the consumption of steel tube and reduce the space occupied by heat exchange equipment, which has good economy and reliability

1. The test specimens and the tests required by this specification shall conform to those described in the latest issue of Test Methods and Definitions A 370.
2. The longitudinal tension test specimen shall be taken from the end of the pipe or, for continuous-welded pipe, it shall be permissible to be taken from the skelp, ata point approximately 90° from the weld, and shall not be flattened between gage marks. The sides of each specimen shall be parallel between gage marks. If desired, the tension tests are permitted to be made on the full section of pipe. When impracticable to pull a test specimen in full section,
the standard 2-in. [50-mm] gage length tension test speci-men shown in Fig. A2.3 of Test Methods and Definitions
A 370 is acceptable.
3. Transverse weld test specimens from electric-resistance-welded pipe shall be taken with the weld at the center of the specimen. All transverse test specimens shall be approximately 1 1⁄2in. [40 mm] wide in the gage length and shall represent the full wall thickness of the pipe from which the specimen was cut.
4. Test specimens for the bend and flattening tests shall be taken from pipe. Test specimens for the flattening test shall be smooth on the ends and free from burrs.
5. All specimens shall be tested at room temperature.
