Reinforced Functional Steel Skeleton Plastic Composite Pipe and Its Technology

通过对钢骨架塑料复合管抗静电、耐温基料、国产化原材料的改性和机理研究,以及对磷化表面处理钢丝技术、管材压力等级系列化结构优化设计及生产配套技术研发,实现增强功能型钢骨架塑料复合管规模化生产,使传统的复合管道除具有双面防腐、耐老化、自示踪性好、抗结垢、寿命长(50年以上)等特点外,还有导静电、耐温等新的特殊功能。增强型钢骨架塑料复合管广泛应用于油田、矿山、化工企业油气集输,以及城市供水、采暖、排污、高压燃气输送等领域,扩大了管道应用领域,目前年产品销量约260km,销售收入达1亿元以上。

This paper focuses on modification and mechanism study of anti-static temperature-resistant base material and domestic rawmaterial for production of steel skeleton plastic composite pipe.Based on phosphate surface treatment technology and optimization ofstructural design for pipe pressure grade series,reinforced functional steel skeleton plastic composite pipe was put into mass production.Asa result,traditional composite pipe can have some special functions,such as electrostatic conductivity and temperature resistance,inaddition to the characteristics of double-sided anti-corrosion,anti-aging,and long service life( more than 50 years).Reinforcedfunctional steel skeleton plastic composite pipe was widely used for oil and gas gathering and transferring of oil fields,mines and chemicalenterprises as well as urban water supply,heating,drainage and transmission of high-pressure fuel gas,expanding the application area ofpipe.Currently,the annual sales of product are about 260 kilometers while the revenues reach 100 million yuan.
