由管道局科学研究院承担的“煤焦油瓷漆及其配套材料研制”项目,于1993年4月6日通过了总公司科技发展局的鉴定。煤焦油瓷漆是世界上使用历史悠久、应用普遍的管道防腐材料。通过近百年的应用实践,证明其防腐效果好、使用寿命长、价格低廉,施工技术和质量检验都积累了成熟的经验,至今仍是国外最主要的管道防腐材料之一,广泛地应用于沙漠、戈壁、海洋、沼泽等各种土壤
The research project of “coal tar enamel paint and its supporting materials” undertaken by the Bureau of Science and Technology of Pipeline Bureau passed the appraisal of Science and Technology Development Bureau of the parent company on April 6, 1993. Coal tar enamel is the world’s use of a long history of pipe commonly used anticorrosion materials. Through nearly a hundred years of application practice, to prove its good anti-corrosion effect, long life, low price, construction technology and quality inspection have accumulated mature experience, is still one of the most important foreign pipeline anti-corrosion materials, widely used in desert , Gobi, ocean, swamps and other soil
