工矿液压设备的高压油管接头漏油,是个普遍存在的严重问题。为了解决这个问题,最近创造出几种新型防漏高压油管接头。这些新型管接头不需对管头做复杂的喇叭口、铃状口或焊接处理,也不需要工艺麻烦、成本较高的法兰盘,而且提高了管接头的可靠性和使用寿命,既经济又适用。 High pressure oil and gas pipe fittings leaks, is a ubiquitous serious problem. To solve this problem, several new leak-proof high-pressure tubing fittings have recently been created. These new pipe fittings do not require complicated bell mouths, bell-shaped mouths or welding processes on the pipe heads, nor do they require flanges with high workmanship and cost, but also improve the reliability and service life of the pipe joints, which is not only economical Also applies.
