输油钢管防腐保温泡沫夹克生产工艺技术近年来在国内发展迅速,使管道工程技术向前迈进一步。“一步法”成型工艺技术中夹克与泡沫间的粘接一直是个技术难题,它是进一步完善“一步法”的关键。胜利油田油建一部机具研究所科研人员已于1987年10月成功地在“一步法”生产线上实现了夹克与泡沫层间的粘接,解决了这个技术难题。这种粘接易于实施,费用低,适用于“一步法”等多种工艺,
In recent years, the production technology of anti-corrosion and thermal insulation foam jacket for oil transmission pipelines has been rapidly developed domestically and has made pipeline engineering a step forward. The bonding between jacket and foam in “one-step” molding technology has always been a technical problem, which is the key to further improve the “one-step” approach. Shengli Oilfield Oil built a research institute of machine tools in October 1987 has been successfully in the “one-step” production line to achieve the bonding between the jacket and foam layer, to solve this technical problems. This bonding easy to implement, low cost, suitable for “one-step” and other processes,
