Abstract

The utility model relates to a steel wire framework reinforced ultra-high molecular polyethylene pipe, which belongs to the technical field of corrosion resistance middle and low voltage pipes. The existing corrosion resistance middle and low voltage pipe has the essential structure that a steel plate is arranged between an inner wall and an outer wall, so once the inner wall is destroyed, pressure or corrosive media can directly act on the steel plate of the pipe and the outer wall, so that the quality and the use reliability of the pipes can be lowered. The utility model has the technical proposal that the inside of the interval between the high-density polyethylene layer 1 and an ultra-high molecular weight polyethylene layer 4 is provided with a high-intensity plastified steel wire screen 3 which is immersed with high-intensity adhesive. The utility model has the advantages of high intensity, high rigidity, high impact resistance, creep resistance, ultraviolet radiation resistance, high abrasive resistance, corrosion prevention on double surfaces, low heat conductivity, good energy saving performance, high reliability, long service life, low cost, sanitation, and innocuity. The performance at the connection point of the utility model is the same with the performance of the pipe, and the fusion technology is mature, so the temperature resistance and pressure resistance pipes can be made.

Description

Steel-wire carcass strengthens the ultra high molecular polyethylene pipe

Technical field: the utility model relates to corrosion-resistant mesolow tubing technical field, is that a kind of steel-wire carcass strengthens the ultra high molecular polyethylene pipe more specifically.

Background technique: the corrosion-resistant mesolow pipe structure that now uses is as being provided with the steel plate layer between inwall and the outer wall, if inwall is in case destroy, pressure or aggressive medium will directly act on the steel plate layer of pipe and quality and operational safety that outer wall makes tubing reduce greatly.

Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is that a kind of steel-wire carcass of design strengthens the ultra high molecular polyethylene pipe.Its technological scheme is: have the high strength that immerses high strength bonding agent 2 to cross plastic-steel silk screen 3 between high-density polyethylene layer 1 and the ultra-high molecular weight polyethylene layer 4.The advantage of this model utility is: intensity height, good rigidly, good impact resistance, have the low coefficient of linear expansion of similar steel pipe, and creep resistance and antiultraviolet irradiation property, wear-resisting property is 5～8 times of steel pipe.Two-sided anticorrosion, have the antiseptic property identical with plastic tube.Thermal conductivity is low, uses winter outer wall need not be incubated, and also uses not dewfall, good energy saving property summer.Inwall is bright and clean, non-scaling, and loss of head is than steel pipe low 30%.With the caliber pipe material wall thickness reduction, pressure rating improves.Pipeline connects the molten connection of employing electric heating, and the performance of joint is identical with pipe performance.The fusion techniques maturation, the pipe fitting specification is wide in variety.Adopt the high plastics of temperature resistant grade,, can make heat resisting and pressure resisting tubing as middle and higher density polyethylene, polypropylene, PP-R etc.Tubing overall reliability height, under normal operation, can reach 50 years working life.In light weight, transportation and easy construction.With low cost, health is nontoxic.

Description of drawings: Fig. 1 plan view, Fig. 2 are the sectional view at Figure 1A place.In the accompanying drawing: 1, high-density polyethylene layer, 2, the high strength bonding agent, 3, high strength crosses the plastic-steel silk screen, 4, the ultra-high molecular weight polyethylene layer.

Embodiment: steel-wire carcass strengthens ultra high molecular polyethylene pipe outer tube wall and adopts high-density polyethylene layer 1, inner tubal wall adopts ultra-high molecular weight polyethylene layer 4, be provided with the high strength that immerses high strength bonding agent 2 and cross plastic-steel silk screen 3 composition plastic alloy layers between inner tubal wall and outer tube wall, the three forms monolithic construction in the mode that merges.The steel wire of reinforcement is in seamless effective protection; also fusion and the interface, slit can not occur fully of plastic alloy layer and inside and outside tube wall simultaneously; well solve simultaneously ultra high molecular polyethylene material and the bonding problem of other materials, therefore eliminated corrosion or damage that interior pressure of pipe or Korrosionsmedium may cause tubing.

Claims

1, steel-wire carcass strengthens the ultra high molecular polyethylene pipe, it is characterized in that: have the high strength that immerses high strength bonding agent (2) to cross plastic-steel silk screen (3) between high-density polyethylene layer (1) and the ultra-high molecular weight polyethylene layer (4).
