What's the difference between steel wire mesh plastic composite pipe and steel skeleton composite pipe?
Comparison of water breakthrough in end face of pipe cut:The steel mesh skeleton plastic composite pipe, connecting factor of the existence of a high performance between the substrate PE and high strength steel wire, the substance of PE modified materials, and PE can be fused into one, under the condition of heating, has strong adhesive properties of the polar bond with steel, make the pipe inside and outside layer and high the strength of steel as a whole, in the process of manufacture, storage and use, between high strength steel wire and PE will not appear gap, even if the two ends of pipe sealing, interlayer channeling water will not appear.The steel skeleton plastic composite pipe, because the clearance must exist between pipe and PE steel plate material, cut pipe, the end is sealed, but the use of electric melting pipe heat sealing is easy to fall off. After installation, the medium will break into the gap between the steel plate and the plastic, which will lead to the decrease of the pressure bearing capacity of the whole pipeline system. Cause the tubing to be damaged at low pressure and cause pipe failure.
First, the production process is not the same, the top man is described in detail;Second: product standards are not the same. The steel wire frame plastic composite pipe carries out CJ/T189-2008, steel skeleton compound pipe, the execution standard is CJ/T123-2004;Third: steel skeleton composite pipe can overhead, steel wire mesh composite pipe can not overhead.
Laying and installation and environmental comparison:The steel mesh skeleton plastic composite pipe, steel pipe in the internal structure of similar metal hose, anti settling effect is good, especially suitable for the underground pipeline, in complex terrain conditions can also use the pipe body (do not exceed the allowable bending transition radius of curvature conditions).The steel skeleton plastic composite pipe, pipe rigidity, poor adaptability of ground subsidence for underground pipeline construction, pipe joint stress concentration, easy to be destroyed.
Comparison of composite structures for tube manufacturing:The steel mesh skeleton plastic composite pipe, with high strength steel wire should be (above 1950Mpa) as the substrate, take two times the combined form, with a 54.7 degree oblique wire wound on the pipe, the pipe under internal pressure to the axial and circumferential uniform dispersion force, a higher safety factor used in determining the wire the diameter and density.The welding of steel skeleton plastic composite pipe, ordinary carbon steel wire for steel wire substrate, although thicker, but the tensile strength is 400Mpa, complex process, product quality fluctuation.
