Qingdao NPA Industry Co., Ltd was founded in 2011. In China. NPA is a leading manufacturer in high-temperature alloy industry in China. We specialize in centrifugal casting tubes used in Float Glass, PV (Photovoltaic), Low-e glass and Rolled Glass Production line, which also are widely used in petroleum & chemical industries including Hydrogen, Methanol, Synthetic Fules, Ammonia, Carbon Monoxide, Ethylene Propylene, Butadiene, and Aromatics reformer/cracker furnaces.
NPA has11 horizontal centrifugal casting machines(under independent property rights) and 2 vertical centrifuge. The unique base and mold design ensures high rotate speed, small vibration and stable running. The rotate speed of automatic centrifuge(NPA property right) can reach over 3, 000 RPM.
The structure of furnace tube is more compact, and long enough to meet customer's requirements. The pouring efficiency per tube is 3 times quicker.
