Internal and external sprayed steel pipe is a composite structure with coating inside and outside, and in 

the middle is a reinforced welded steel pipe. It overcomes the defects of easy corrosion, pollution, short 

service life, low strength and large expansion of plastic pipe, and has the common advantages of steel 

pipe and plastic pipe, such as good oxygen insulation and high deformation. Rigid and high strength, 

buried pipes are easy to detect and so on. Compared with other types of steel pipes, the main bearing 

layer of the inner and outer sprayed steel pipes is completely taken by the welded steel pipes in the 

composite pipes, and the plastic layer only plays the role of corrosion protection, so the bearing capacity 

of the pipes is not affected by the temperature change and the aging of the plastic layer.
