1、仅供参考For personal use only in study and research; not for commercial use一、玻纤增强HDPE石油化工复合管的产品概述-玻纤增强HDPE石油化工复合管是通过HDPE塑料与玻璃纤维复合而成。玻纤 增强HDPE石油化工复合管综合了塑料和玻璃纤维的一些特性。HDPE无臭、无 毒，具有良好的耐寒性。玻纤增强HDPE石油化工复合管不但具有普通塑料管质轻、搬运装卸便利、施工 简易、耐化学药品性能优良、流体阻力小、使用寿命长、维护方便等特点，而且玻纤 增强HDPE石油化工复合管的机械强度远远大于普通HDPE管的机械强度，同时提高 了管的耐温

2、性能、热变形温度，并降低了尺寸不稳定的特点，克服了普通HDPE塑料 管遇高温易蠕变、使用寿命短等缺点。我们突破并实现了 HDPE管大口径化的生产。玻纤增强HDPE石油化工复合管化学稳定性好，能耐大多数酸碱盐的腐蚀(除了强 氧化性的酸外)，不洛于石油，可用于含有酸碱土质的石油管道。玻纤增强HDPE石油化工复合管不但进一步拓宽了塑料管的使用范围，而且符合 国家倡导的“以塑代钢”、“节能减排”、“绿色环保”的政策，有着广阔的市场发展前 景。1. Product overview of glass fiber reinforced HDPE petrochemical pipeGlass fiber

3、reinforced HDPE petrochemical pipe, is compounded by HDPE and glass fiber So it has some characteristics of HDPE and glass fiber. HDPE is non-toxic, odorless. It also has excellent cold resistanceGlass fiber reinforced HDPE petrochemical pipe has distinguished features of lightweight, handling conve

4、nience, simple construction, excellent chemical resistance properties, small fluid resistance, long serving life and convenient maintenance. Furthermore, compared with the common HDPE pipe, the mechanical strength of the glass fiber reinforced HDPE composite petrochemical pipe is far better than com

5、mon HDPE pipe At the same time, it improves the pipe high temperature performance, high thermal deformation temperature, and lowers dimensional instability. It also overcomes the shortcomings of common HDPE pipe like easy to creep in high temperature, short service life and so on. And we realized a

6、breakthrough in large diameter HDPE pipe productio n.Glass fiber reinforced HDPE petrochemical pipe has good chemical stability. It can resistant most of acid and alkali corrosiveness (except strong oxidizing acid), and doesnt dissolve in oil, so it can be used as oil pipeline in acid and alkali soi

7、lGlass fiber reinforced HDPE petrochemical pipe not only widens the plastic pipe application field but also accords with national policy: Hsteel to plastic 舄 Henergy-saving emission reduction n, environment protecting11 It is doomed to have great prospects for market development.二、玻纤增强HDPE石油化工复合管的优点

8、玻纤增强HDPE石油化工复合管不锈钢管具有优异的耐酸碱腐蚀性，在腐蚀的 环境条件下不发生化学反应，适合各种酸 碱土质的铺设耐腐蚀性较差，在酸碱土质铺设要经 过特殊处理正常使用寿命可达50年正常使用寿命只有20年左右具有很强的耐压性能，抗冲击韧性， 环刚度高，拉伸强度是普通HDPE塑料管 的八倍以上具有很强的耐压性能物理机械性能强度达到钢管物理机 械性能强度的80%,但重量却只有钢管的 20%物理机械性能强度好连接方式釆用法兰连接，施工方便、 操作简单、安装工效高管材、管件连接方式釆用焊接，施工 不方便，操作较复杂，安装工效较低抗静电、防爆抗静电、不防爆纵向收缩率为0.25%纵向收缩率为0.05
