SA213 T91 Boiler Tube manufacturer in India
T91 Tube Material is acidic and chloride resistant. It is used in high temperature applications. Specifications of the tubes are ASTM A213 and A691. Multi Metals (India) is a leading manufacturer and supplier of the T91 Tube Material made products. The dimensions of the tubes are covered by ASTM, ASME and API standards. The tubes generally range from ½ inches to 5 inches in diameters and the wall thicknesses range from 1mm to 200mm.
Depending on the need of the application, the length can vary up to 2500mm. The T91 Boiler Tube as the name suggests is used in high pressure, high temperature applications like the boilers. There are different pressure capacities of the tubes which are measured with the schedules. The schedules range from sch20 through XXS. Since the material is resistant to acids and chlorides, it is also known as the T91 Buffer Tube because it buffers the said components from reacting with the tubes. Annealing, normalizing and quenched methods are used to increase the hardness of the material.
But the Tube T91 has to be cooled in a hydrogen atmosphere to make sure that the bright surface is not altered due to oxidation at high temperatures. Once cooled, the tube is ready for application. The material has carbon, manganese, phosphorus, sulfur, silicon, molybdenum and chromium in the composition. The composition of the ASTM A213 T91 Tube provides it with 205MPa minimum yield strength and 585MPa minimum tensile strength. It is also very hard compared to other grades of the similar alloys. The hardness is 250 HB max. You can place your orders for the Asme Sa213 T91 Tube with us and can also get a complete price list upon contacting us
