Steel mesh skeleton polyethylene pipe
Steel mesh skeleton polyethylene pipe Profile
Steel mesh skeleton polyethylene pipe is high strength steel wire mesh around the spiral winding framework to strengthen the body to high-density polyethylene(HDPE)as matrix, and high-performance adhesive resin ofHDPEmodified within the wire frame and , outside the story closely linked density polyethylene, a new pipe.Because of the high-strength steel wire reinforcement was being coated in a continuous thermoplastic, steel mesh skeleton so polyethylene steel composite pipe and plastic pipe to overcome the shortcomings of their own, but to maintain a steel pipe and plastic pipe with their respective advantages.
Steel mesh skeleton polyethylene composite pipe, using a high-quality materials and advanced production technology, so that it has a higher pressure resistance.Meanwhile, the composite pipe has excellent flexibility, suitable for long distance underground with the water supply, gas pipeline system.Steel mesh skeleton polyethylene pipe used in pipe is fused polyethylene pipe.Connection, the use of heat pipe inside the outer body of the plastic pipe and melt the plastic inner tube, pipe and pipe fittings to connect reliably.
Steel mesh skeleton Features polyethylene composite pipe
Steel mesh skeleton polyethylene pipe with corrosion, no scaling , Smooth, low resistance, thermal insulation is not wax, wear-resistant, light weight plastic pipe and other common features, and its unique structure also created the following characteristics:
(1)Good creep resistance, long-lasting high mechanical strength
。As the plastic at room temperature and creep occurs under stress, under stress at a high sustained brittle fracture will occur, so pure plastic pipe allowable stress and pressure is very low (generally less than1.0Mpa).The mechanical strength of steel is about10times thermoplastics, and in the plastic range is very stable temperature creep does not occur.The mesh wire frame and plastic composite, steel mesh skeleton can be effectively bound by plastic creep rupture strength of plastic itself is also greatly improved.Therefore, steel mesh skeleton polyethylene pipe plastic pipe than the allowable stress doubling.
(2)Good heat resistance
The strength of plastic pipe used in the temperature range generally decreases with increases in temperature, a temperature increase of about10℃its strength reduced by10% ormore.As the steel mesh skeleton strength polyethylene composite pipe about2 / 3is assumed by the wire mesh frame, so its intensity decreases with temperature increase is lower than the extent of any pure plastic pipe.10℃，Experimental results show that for every increase of10℃, steel mesh skeleton polyethylene pipe strength decreased below5%.
(3)Rigidity, good impact resistance, dimensional stability, have moderate flexibility, hardness and softness
Modulus of elasticity of steel is usually high-density polyethylene elastic modulus of200times, due to the strengthening of the role of the skeleton of steel wire to make steel mesh skeleton polyethylene pipe rigidity, impact resistance and dimensional stability than any of the pure plastic pipe.And because the mesh of steel skeleton itself is a flexible structure, so that the composite pipe in the axial direction there is a certain flexibility.Therefore, the pipe has just, with soft features, in the handling, transportation, installation and operation of adaptive performance in terms of superior reliability.Ground bearing installation can save the number of low cost; underground installation can effectively withstand the due settlement, sliding, vehicle, etc., causing sudden impact load.Small diameter pipe may be appropriate to bend, or snake-like layout with undulating terrain layout, saving fittings.
(4)Thermal expansion coefficient
As the plastic tubes steel linear expansion coefficient of10.6~12.2 × 10-6(1/℃), pure linear expansion coefficient of plastic pipe170 × 10-6(1/℃), the skeleton of steel wire mesh polyethylene steel composite pipe in skeleton of the constraints, the thermal expansion of composite pipe is greatly improved, lower than any of the commonly used plastic pipe, test, steel mesh skeleton polyethylene pipeline expansion coefficient of35.4~35.9 × 10-6(1/℃), only ordinary carbon steel pipe3to 3.4times.Experimental results show that underground installation is generally no need for thermal compensation device, like laying pipe winding can be played using the absorption (or release) the role, so that the installation costs.
(5) Cracking does not occur quickly
Pure large diameter plastic pipe, especially at low temperatures, pure plastic pipe hoop stress the role of durable, easy to produce from the local defects, stress concentration caused by the rapid cracking (a few hundred meters to kilometers above the moment), so the pipe on the current international resistance to rapid crack performance plastic madehigh demands, and low-carbon steel does not exist the problem of brittle fracture, the presence of steel mesh and plastic deformation to produce the stress will not reach the critical point of rapid crack.Therefore, in theory, steel mesh skeleton polyethylene pipe does not exist fast cracking.
（6) Steel, plastic composite of two materials uniformly reliable
Currently on the market-plastic composite pipe as steel, plastic composite surface is continuous between the rules of theinterface,long-term use in alternating easy to delamination under stress, resulting in junction leakage, internal bottlenecks like contraction, blockage and failure .Compared with steel mesh skeleton polyethylene pipe is a special hot melt through the network structure (modifiedHDPE)plastic and steel mesh closely integrated and seamless.Each binding two materials uniformly large, small stress concentration.
（7) Double-sided anti-corrosion
Steel mesh skeleton through a dedicated hot melt adhesive layer being in the plastic compound, inside and outside pipe surfaces have the same corrosion resistance, wear-resistant, smooth wall, conveying resistance, no scaling, no wax, energy-saving effect is obvious, for the underground transmission and corrosive environmental conditions is more economical.
(8)Since the tracer is good
Because the presence of steel mesh skeleton, so the steel mesh skeleton buried polyethylene pipes can usually find ways to detect the magnetic orientation, avoid other damage caused by excavation works.And this is pure damage plastic pipe and other non-metallic tube to produce the most damage.
(9) Convenient and flexible adjustment of product structure and properties
By changing the wire diameter, from the gateway, the plastic layer thickness, and types of plastic to adjust the product structure and performance to meet different pressure, temperature, corrosion requirements.
(10) Dedicated fused joints, variety, very fast and reliable installation
Steel mesh skeleton polyethylene pipe connected by electrical connections and hot-melt flange in two ways.Electrical connection is complex hot melt into the electric melt pipe fittings, the inside of the pipe embedded in the surface of the heating wire electricity to heat. First the inner tube surface melting resulting melt, melt expansion and the gap filled with pipe fittings, pipe until the outer surface of the melt also produced, both with each other molten melt together, cooling after molding, pipe and pipe fittings close connected to one
