ASTM A213 T91 Tubes are processed by heat treatment, cold drawn, and pickling finishes, cleaning and smooth surface inside and outside. A213 T91 Tubing has the capacity of standing in high pressure and high temperature conditions. Different grades of boiler tube suit to different type of boilers; it has to meet complex boiler environments, like boiler pressure, temperature, heat pass location, steaming rate, flow direction etc. T91 Boiler Tube has good corrosion resistance and high strength in high temperature and good properties result from addition of alloys and carbon. Hence it can meet high pressure and temperature requirement.
ASME SA213 Grade T91 is able to fight high pressures, they are also widely used in high-pressure applications like Oil and Gas infrastructure, refineries, hydraulic cylinders and in hydrocarbon industries. A213 Gr T91 Seamless Tube has a higher operating pressure and are more effective in withstanding mechanical stress than A213 Gr T91 Welded Tube.
All Chhajed products are manufactured under strict process control and monitored throughout the production process. They go through several checks to ensure that the product delivered is of finest quality!
