ASTM B407 Incoloy 800H Tubes details-
Incoloy tubes are solid solution iron, chromium and nickel alloy tubes. Typically, these are offered as one, dual certified alloying meeting the elemental requirements of alloy. This material is restricted titanium and aluminium grade. This results in higher creep and stress to rupture properties. These tubes have superior resistance to creep and stress rupture. Typically, these tubes are used for applications that include long term service in the higher temperatures where resistance is required from carburization and oxidation and other types of higher temperature corrosion.
Power generation, hydrocarbon processing, and heat furnaces are some of the common applications of ASTM B407 Incoloy 800H Tubes. Due to the presence of alloying elements structure of tubes get resistance from sulfidation. The presence of nickel content increases the resistance to nitriding.
The hot working operations of tubes are performed in the temperature between 1600 deg F and 2200 deg F. also, no forming operation should be performed in the temperature below 1600 deg F. the preheating of tools is required to avoid the chill. The hot working operation performed in fast as possible avoiding higher temperatures between 1000 deg F to 1400 deg F. however, the cold working operation is performed in the annealed condition.
Quality-
We are committed to never compromise with the quality of the manufactured range of products. Thus, to do so we follow and apply strict quality control measures. The quality measures were developed by professionals who serve our clients for a long time. Our strong focus is to manage and implement quality standards in each level of productions. This assures the reliability of products even after manufacturing. With the testing procedures, damaged products can be identified and removed. Also, a damaged lot will be replaced if the fault is major.
Mainly, two types of testing are performed by us are destructive testing and non-destructive testing.
Destructive testing-
• Tensile test
• Hardness test
• Mechanical test
• Compression test
• Leakage test
• Pressure test
• Thermal stability analysis
Non-destructive testing-
• Pitting corrosion test
• IGC test
• Positive material test
• Macro test
• Micro test
• Chemical analysis
• Radiography
• Ultrasonic test
We certify our quality standards by providing documentation and certificates to our customers. Those include fumigation certificates, quality assurance plan, mill test report, specification guide, product invoice, (NBAL) test report, attested certificates, raw material test report, etc.
The delivery of ASTM B407 Incoloy 800H Tubes is done in the standard packing of wooden cases, wooden pallets, plywood pallets, and cartons. Moreover, the extra protection of end caps is also provided on tubes to prevent damages while exporting. Also, the plastic shield provides protection from contamination while exporting.
