Boiler tubes

Boiler tubes is tubes used for boiler systems, like boilers for civil use in life, general industrial boilers, locomotive boilers and thermal power boiler. According to different steam pressure, thermal power boilers are divided to low, medium, high pressure, high pressure, sub-critical pressure, supercritical pressure boilers, ultra-supercritical units. Production standards and materials for boilers tubes: BS3059 Steel boiler and superheater tubes
