Alloy Boiler pipe and tube standard and specification
It takes an uncompromising level of quality to manufacture pressure tubing and piping. AGICO understands the critical end-use applications and maintains the strictest production standards and procedures required to meet the precise ASTM/ASME specifications required for heat ex-changers, condensers and boilers. We offer complete, non-destructive testing equipment to ensure our products consistently meet our customer’s specifications and worldwide quality standards.
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, super-critical pressure boilers, ultra-supercritical units.
