The invention relates to a steel wood-plastic composite tube which comprises a carbon steel tube. The inner surface and the outer surface of the carbon steel tube are respectively provided with a concave-convex combining part, and concave-convex grains or pits and protrusions are arranged on the concave-convex combining parts on the inner surface and the outer surface of the carbon steel tube. An anticorrosion wood-plastic composite material layer and a fire prevention wood-plastic material layer are arranged on the inner surface and the outer surface of the carbon steel tube respectively in a pressure casting mode. The outer surface of the fire prevention wood-plastic material layer is further coated with a fire prevention coating layer. The steel wood-plastic composite tube has high rigidity, can bear high water pressure, further has the high anticorrosion function and the high fire prevention function, is particularly suitable for fire control systems of high-rise buildings and has large using value and market value.
Description
technical field [0001] The invention relates to special pipes, in particular to a steel-wood-plastic composite pipe. Background technique [0002] Fire accidents are more harmful and frequent disasters in modern society. According to statistics in recent years, fire accidents with mass deaths and injuries occur almost every year in our country, which poses a great threat to the lives and property safety of the masses. Take the fire in 2007 as an example. Ten people were killed and nine were injured in the fire at Mingdian Coffee Tea House in Zhangmutou Town, Dongguan, Guangdong Province. Twenty-one people were killed in the Wenfu Building fire accident in Wenzhou City, Zhejiang Province. The "1.2" Dehui International Plaza fire in Urumqi, Xinjiang killed three people. Famous heroes and martyrs are buried in the ground, and the lessons for people are profound. After learning from the pain and reflecting on fires, in addition to the lack of fire safety awareness and knowledge...
