The company adopts the most leading and mature process in tube-making industry, which belongs to core technology. It vibrates evenly, strongly with high frequency and can be adjustable, which makes it possible for the application of hard concrete. Concrete with 0 slump and ０－２４s work greatly improve tube strength and impermeability. Hard concrete makes instant demoulding possible. Therefore, a steel mould can be used to organize the continuous production of a certain caliber product. The mixing system is fully automated and ingredients are electronic metering and computer control, which make quality of concrete stable and reliable. The steel frame is produced by seam welder, ensuring firm welding points of the skeleton and uniform pitch.
