PE過路頂管

　　鋼絲網骨架聚乙烯復合管是以包覆處理后的高強度鍍銅鋼絲連續纏繞成型的芯層為增強骨架，以高密度塑料(聚乙烯)為基本材料，采用專業的熱熔膠(高性能改性聚乙烯粘接樹脂)，在生產線上通過連續分次擠塑復合成型的管材。

　　廣泛應用于長距離埋地供水。供氣管道系統，是目前國內替換鋼管等傳統管道的優選管材。

The steel wire mesh framework polyethylene composite pipe is a kind of reinforced core layer formed by continuouswinding of coated high strength copper-plated steel wire, and high density plastics (polyethylene) as the basicmaterial. It adopts professional hot melt adhesive (high-performance modified polyethylene adhesive resin) tocontinuously extrude and compound the pipe on the production line in stages.
It is widely used in long-distance buried water supply. Gas supply pipeline system is the preferred material forreplacing traditional pipes such as steel pipes in China.

產品性能

　　◆具有超過塑料管強度的較高強度、剛性、抗沖擊性。雙面防腐，具有與塑料管相同的耐腐蝕性能。

　　◆使用溫度提高， 導熱系數低，冬季使用外壁不需要保溫，夏季使用亦不結露。

　　◆內壁光潔，不結垢，水頭損失比鋼管低30%。

　　◆管道連接采用電熱熔連接， 技術成熟，電熱熔接頭抗軸向拉力能力強，管件品種多。

　　◆重量輕， 運輸及施工方便，管材總體可靠性高。在正常條件下，使用壽命可達50年。

It has higher strength, rigidity and impact resistance than the strength of plastic pipe. Double-sided　anti-corrosion, with the same corrosion resistance as plastic pipes.
The use temperature increases, the thermal conductivity is low, the external wall does not need thermal　insulation in winter and does not condensate in summer.
The inner wall is smooth and scale-free, and the head loss is 30% lower than that of steel tube.Pipeline connection adopts electro-thermal fusion connection, which has mature technology, strong resistance to　axial tension of electro-thermal fusion joint, and many kinds of pipe fitings.
Light weight, convenient transportation and construction, high overall reliability of pipes. Under normal　conditions, the service life can reach 50 years.

執行標準

　　衛生指標符合GB/T17292《生活飲用水輸配水設備及防護安全性評價指標》的規定。產品標準符合CF/T189- -2007。

The hygienic index conforms to GB/T 17292 "Safety Evaluation Index of Domestic Drinking Water Transportationａnd Distribution Equipment and Protection". The product standard conforms to CF/T189-2007.

技術要求

　　顏色一般為黑色，也可根據我供需雙方協商決定。管材內、外表面應該光滑平順，允許有自然收縮:的微小凹坑和凸起，不允許有氣泡裂口、分解變色及明顯劃傷，管材兩端切割平整。

The color is usually black. It can also be decided by negotiation between the supplier and the buyer. The inner andouter surfaces of the pipes should be smooth and smooth, allowing for natural shrinkage of small pits andprotrusions, not allowing bubble cracks, decomposition and discoloration and obvious scratches, smooth cutting atboth ends of the pipes.
