What's the difference between the steel wire mesh composite pipe and the steel skeleton plastic composite pipe?
Steel skeleton plastic composite pipe: steel mesh welding and plastic extrusion simultaneously, the pipe wall inside and outside the plastic layer through the metal mesh tube wall in the middle of the connection as a whole, no obvious interface between steel and plastic, the overall structure is similar to that of reinforced concrete, two kinds of composite material completely as a whole, stable and uniform quality, each part of the pipe. There is no delamination hazard.
1, steel skeleton plastic composite pipe: with reinforced skeleton full wiring fuse sleeve for welding, welding area is large, high reliability.2, steel mesh skeleton PE: General supporting the use of pure PE electric melting sleeve connection, non reinforced skeleton, fused into the middle jumper, the welding area is small, low reliability.
1, steel skeleton plastic composite pipe fittings including: all electric melting sleeve, elbow and three pass, as part of the interior have reinforced steel frame, with a pipe supporting good, pressure pipeline system and heat resistance, and pipe and pipe size consistency.2, steel mesh skeleton PE: general use of frameless pure plastic pipe and pipe fittings supporting pressure level below the pipe body or the pipe wall thickness due to the large part of the pipe diameter is reduced. At the same time, there is no skeleton pipe fittings (including fused sleeve), the resistance to pressure and temperature resistance is obviously lower than that of the pipe, and the joints of the pipe and the fittings are easy to break.
1, steel skeleton plastic composite pipe wall of the inner and outer layers of plastics by metal mesh tube wall in the middle is connected (in form of a reinforced concrete structure), two composite material completely as a whole, because the steel surface is very smooth, no edges, the flow resistance in the molding process of the plastic extrusion is small and uniform so, each part of the pipe quality uniform and stable. Because the mesh is welded, the grid spacing of the skeleton is uniform, the structure is stable, and the supporting effect of the plastic is strong.2, steel mesh skeleton plastic (polyethylene) composite pipe: winding steel wire net forming in hot melt under the action of the inner and outer layers of plastic bonded together, because polyethylene material itself difficult to stick the adhesive properties, general effect, due to multiple molding, uniform quality of pipe is poor. Because the steel wires are only wrapped together, without welding, the mesh spacing of the steel wire mesh is uneven, the structure is unstable, and the local strength of the steel pipe is very low at the place where the steel wire spacing is large. The shrinkage of the end of the pipe is serious due to the poor supporting effect of the steel mesh on the plastic.
Steel mesh skeleton plastic (polyethylene) composite pipe: first inner plastic extrusion, plastic molding in the inner wall and tube coated a layer of hot melt adhesive and wire winding, then coated with a layer of hot melt extrusion molding, multiple outer plastic last way. There is a clear interface between pipe layers and easy delamination, delamination after the pipe internal wire winding separation layer and the plastic layer, in the transport of corrosive medium case will cause serious corrosion of the steel wire layer, the main bearing pipe is damaged, because the bearing capacity of the remaining part of the wire layer is plastic after corrosion is very low, there may be a tube explosion phenomenon occur even at low pressure. Even if there is no corrosion problem, because at the end of the tube portion of the wire without a fixed (bonding effect is not good), under the pressure of the steel wire sliding in the plastic layer, caused by the pipe end part no longer have wire reinforced, become pure plastic pipe wall thickness is very thin, very easy to appear in this section tube.
