摘要
PVC管材在使用中的连接形式大体上分为两种:一是采用管端承插部位直接涂上胶水的粘接形式;二是采用橡胶密封的承插形式,该形式密封性较好,又有一定的挠度和轴向伸缩,满足了工程要求,普遍用于给排水和大型改水工程、电缆保护管等。
Two kinds joint form was introduced for applying to heavy-caliber PVC pipe, the lubricant was spread around the orifice or the rubber was installed correctly ring into the slot. But the second joint technique was extensive use in water supply and drainage, fields water conservancy project engineering, cable sleeve etc, owing to better preferable airproof performance, the flexibility and axial adjustment can satisfy engineering requirement.
