ASTM A209 T1A steel pipe has strong heat preservation and high corrosion resistance. It is suitable for dark or open decoration. Clean, nontoxic, safe and hygienic. All the performance indexes meet the requirements of the ministry of health.
The inner wall of ASTM A209 T1A steel pipe is smooth without corrosion and scaling, and the flow rate is 25% - 30% higher than that of metal pipe with the same inner diameter. There is no diameter loss at the connector.
ASTM A209 T1A steel pipe adopts special process. The convex network pattern is processed on the inner wall of ASTM A209 T1A steel pipe, which greatly increases the friction between the outer metal pipe and the inner plastic pipe, thus effectively reducing the inconsistency of thermal expansion between the inner and outer pipes.
The linear expansion coefficient of the steel plastic composite pipe is 2.5×(1 / 100000) /℃, and its service life is five times that of the galvanized steel pipe. The installation is convenient and reliable. The ASTM A209 T1A steel pipe is connected by quick fitting connector, which is convenient and fast without threading.
