ASTM A691 alloy steel grade 91 welded pipes specification typically includes the nominal pipe size, schedule, or wall thickness & length. Depending on the application requirements, the pipes can range from small diameters to larger sizes. Selecting the appropriate pipe dimensions based on the specific project needs is important.

ASTM A691 alloy steel grade 91 welded pipes have excellent high-temperature capabilities. They can withstand elevated temperatures up to approximately 600°C (1112°F) while maintaining their mechanical properties. The pressure limits depend on the pipe dimensions, wall thickness & specific design standards.

ASME SA691 Grade 91 alloy steel welded pipes have been specifically designed for welding applications. They possess good weldability & allow for easy welding using common welding techniques such as gas tungsten arc welding (GTAW) or shielded metal arc welding (SMAW).
