钢丝网骨架塑料复合管
浙江嘉兴冷拉扁钢厂

  钢丝网骨架聚乙烯复合管是以包覆处理后的高强度镀铜钢丝连续缠绕成型的芯层为增强骨架,以高密度塑料(聚乙烯)为基本材料,采用专业的热熔胶(高性能改性聚乙烯粘接树脂),在生产线上通过连续分次挤塑复合成型的管材。

  广泛应用于长距离埋地供水。供气管道系统,是目前国内替换钢管等传统管道的首选管材。

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.

 

产品性能

  ◆具有超过塑料管强度的较高强度、刚性、抗冲击性。双面防腐,具有与塑料管相同的耐腐蚀性能。

  ◆使用温度提高, 导热系数低,冬季使用外壁不需要保温,夏季使用亦不结露。

  ◆内壁光洁,不结垢,水头损失比钢管低30%。

  ◆管道连接采用电热熔连接, 技术成熟,电热熔接头抗轴向拉力能力强,管件品种多。

  ◆重量轻, 运输及施工方便,管材总体可靠性高。在正常条件下,使用寿命可达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.

 

执行标准

  卫生指标符合GB/T17292《生活饮用水输配水设备及防护安全性评价指标》的规定。产品标准符合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.

 

技术要求

  颜色一般为黑色,也可根据我供需双方协商决定。管材内、外表面应该光滑平顺,允许有自然收缩:的微小凹坑和凸起,不允许有气泡裂口、分解变色及明显划伤,管材两端切割平整。

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.
