由中国北方工业公司凌云机械厂和澳大利亚工业管道有限公司、伊期坦·福莱威尔有限责任公司合资兴办生产塑料煤气管道的亚大塑料制品有限责任公司,于87年7月3日在河北省涿州市成立。 鉴于塑料管道具有耐腐蚀、成本低、便于安装、使用寿命长等特点,因而,“以塑代钢”用于输送水、油、煤气、在世界范围内已形成发展的必然趋势。就塑料煤气管道而言,其使用寿命可超过50年,然而,一般钢制和铸铁煤气管道的使用寿命仅有20年左右。1985年,澳大利亚工业管道有限公司在天津安装塑料煤气管道,并在体院北小区进行了试铺,用
Established a joint venture between China North Industries Corporation Lingyun Machinery Plant, Australia Industrial Pipeline Co., Ltd. and Yichangtan Freightwell Co., Ltd. to establish a plastic gas pipeline limited company, YaDa Plastic Products Co., Ltd., on July 3, 87 in Hebei Shengzhou City was established. Since plastic pipes are characterized by corrosion resistance, low cost, ease of installation, and long service life, the “plastic steel” is used to transport water, oil, and gas, and has become an inevitable trend in the world. In the case of plastic gas pipelines, the service life can exceed 50 years. However, the service life of general steel and cast iron gas pipelines is only about 20 years. In 1985, Australian Industrial Pipeline Co., Ltd. installed plastic gas pipelines in Tianjin and conducted trial installations in the North Campus of the Sports Institute.
