Product Description

ASTM A213 Gr. T11 ASME 36.10M Seamless Alloy Tube 

ASTM A213 (ASME SA213) tubing has been widely used in high temperature services especially for the boiler and superheater. Tube material could be in alloy steel and stainless steel, and manufactured in seamless of hot rolled or cold drawn. so this pipe usually used in very important places and the price is much higher than normal carbon pipes. Common grades are T9, T11, T12, T21, T22, T91 and stainless grades in TP304 or TP316.
 

SA213 T11 boiler tube, properties of hot strength makes it suitable for use in pressure-bearing plants in temperature up to 1,000°C. It has excellent fabrication characteristics necessary for high temperature boiler plant construction. In pressure vessel construction and power station engineering, excellent creep rupture strength is one of the most important properties of materials used. The operating conditions in the newly constructed power stations are critically set on by the recent developments in T11 boiler tube fabrication. In this fabrication by the use of heat resistant high-alloy steels it allows the determination of reliably improved supercritical steam characteristics. A213 T11 tubing not only improves the material efficiency but also allow reducing the volumes of materials, both of which results into positive economic benefits.  Moreover, the more severe the climatic conditions forced on combustion emissions, the more effective and productive sa213 T11 tubing becomes. Outstanding hot strength properties of it make it use excellent for resistance to hot gases.

The working temperatures for sa213 T11 materials start above 550°C. The properties for pressure vessel fabrication may be verified by reviewing ASTM a213 T11 Tube material long-term strength values and design characteristics that can be determined over periods of up to 200,000hrs through creep tests. The chromium content at the inner and outer surface of A213 gr T11 Seamless tube determines the corrosion and oxidation, a technique was developed to safe costly alloying elements and makes enough chromium available to provide improved oxidation behavior at the outer tube surface. Although the loads that act on ASME SA213 Grade T11 Tubes in heat resistant materials diverse and it can be determined by estimation and can be managed by right chemical elements and correct design. However, incident has shown that outside effect occur during the service life of plants, which cannot be predicted at the planning and design stage, as they largely result from the actual working conditions to which the Alloy Steel T11 Seamless Tubing exposed and most of these effects are related to high-temperature corrosion. Within the limits of the acceptable temperature ranges, heat resistant austenitic steels generally provide excellent resistance to combustion gases with sufficient excess air.
