Product Overview - ASME SA106 Grade C Welded Pipes
ASME SA106 Grade C is a specification for high-temperature seamless carbon steel pipes, widely used in refineries, power plants, and pressure systems.
However, in practical industrial usage, welded pipes equivalent to SA106 Grade C are manufactured to meet similar chemical composition and mechanical properties, offering a more economical alternative for non-critical applications.
These welded pipes are produced using ERW or EFW processes, ERW or EFW processes,
They are suitable for high temperature service, structural applications, and general industrial pipelines, where seamless pipes are not mandatory.
