How to improve the bonding strength of polyurethane steel composite pipe
- I recommend that you can see the double metal composite tube and memory stainless steel composite pipe, which is characterized by extremely high impact resistance, high pressure resistance, high temperature resistance, corrosion resistance, long service life and easy installation.s
What is the difference between PPR pipe and aluminium plastic pipe?
- From the high temperature performance, long-term use temperature of aluminum pipe GB is 95 DEG C, maximum temperature is 110 DEG C, can fully meet the need of household water; PE pipe as the temperature increases the performance decreased rapidly, only cold water transport; long-term use of GB PP-R temperature is 70 DEG C, the highest temperature is 95 C, there are some limitations in the use of hot water tube.s
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.s
What are the advantages and disadvantages of PE composite pipes for water supply?
- PE composite pipes have a wide range of standards.Simply put: CJ/T 123124, water supply steel skeleton, polyethylene plastic composite pipeAdvantage：1, pipes, pipe fittings have reinforced skeleton. Pipe is welded steel wire, pipe is punched steel plate. (other standard pipe fittings are made of pure PE pipe fittings)2, and PE ratio, good anti cracking performance. It includes: slow crack growth and rapid crack cracking.3 and CJ/T 123, the standard is nominal internal diameter. With the valve, instrument, through the national standard flange matching, convenient and quick.The advantages and disadvantages of other equivalent PE pipe line.s
Is there any difference between steel wire mesh and polyethylene composite pipe for water supply and fire protection?
- Because the high strength steel wire reinforcement is coated in the continuous thermoplastic, the composite pipe overcomes the defects of the steel pipe and the plastic pipe, and maintains the respective advantages of the steel pipe and the plastic pipe.s
Rpap5 butt welded aluminum plastic composite pipe and PB pipe which is good?
- The same PPR tube also has special belt wire fittings, a hot PPR, a head rest outside the wire or wire. Wow and iodine spy Yan paid winter riveting inclined towersThen the two are threaded, hoping to help friendss
What is a composite pipe?
- The composite pipe, as the name suggests, is composed of two layers (including two) of a pipe pipe by some above multilayer structure and processing technology of the compound into the Aluminum Alloy as our factory production of plastic composite pipe, the outer pipe is Aluminum Alloy tube, inner tube for thermal plastic pipe, two layer structure the pipe through prestressing Compositess
What's the difference between the steel wire mesh composite pipe and the steel skeleton plastic composite pipe?
- 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.s
