| 详细介绍： pph管
PPH 管材、管件采用进口原料生产，执行DIN8077/8078 标准。产品主要适用于钢厂的薄板酸洗及废酸回收再生系统，也可用于化工、环保、电厂、食品加工等领域。pph管是FRPP管的延伸产品，主要是其分子都是由β-结晶方式，所以耐高温和耐腐蚀性都比FRPP要强，但价格要比FRPP要贵很多，主要用在钢厂酸洗方面。FRPP和PPH 其80%性能都基本相同。pph管PP-R是分冷热水管，主要用在民用给水方面。但其耐腐蚀，高温性能基本与FRPP管相当，有时候也会选择pph管来替代PPH管但概率不是很高，毕竟PPH直管是专门应用于工业方面，PP-R用于民用。PPH管(均聚聚丙烯管)，其原材料经过β改性，具有均匀细腻的Beta晶型结构，具有极高的化学稳定性和耐高温性，广泛应用于钢厂（酸洗、酸再生、酸雾）、烟气脱硫、工艺冷却水和化工行业的耐腐蚀性介质输送。
PPH pipes, pipe fittings using imported raw materials production, performing DIN8077/8078 standard. Major products applicable to steel sheet pickling waste and recycling of the system can be used in chemical industry, environmental protection, power plant, food processing, etc. PPH pipe is FRPP tube extension products, mainly is the molecules are made by beta crystallization way, so high temperature resistance and corrosion resistance are better than FRPP, but prices are much more expensive than FRPP, mainly used in steel pickling aspects. FRPP and PPH its 80% performance are basically the same. PPH tube PP - R is hot and cold water points, mainly used in domestic water supply aspects. But its corrosion resistance, high temperature performance basic and FRPP tube quite, sometimes also can choose pp-r pipe to replace PPH tube but probability is not very high, after all, PPH straight tube is specially applied to industry, PP - R for civilian use. PPH tube (homopolymerization polypropylene pipe), its raw material after β modification, with uniform exquisite Beta crystal type structure, high chemical stability and resistance to high temperature resistance, widely used in steel mill (acid, acid regeneration, acid mist), flue gas desulfurization, process cooling water and chemical industry resistance to corrosion medium delivery.
