1、膨胀节一、名词解释膨胀节又称补偿器，伸缩节（器）。是现代管道工程系统不可缺少的重要环节。适用于各行各业，只要有管道的地方就有膨胀节，如：石化、仪表、航天、化工、电力、水泥、冶金，钢厂，建筑，制药，供热，市政工程，天然气等。二、膨胀节的作用管道系统在停机和开机两种不同状态下，会因温度变化，造成管道的热膨胀或冷收缩。如果这些膨胀和收缩得不到补偿（消除或平衡），就会造成系统的严重损坏，使系统不能正常工作。膨胀节就是用来吸收这些膨胀和冷收缩的。三、产品分类1、按材质分：金属膨胀节/非金属膨胀节2、按形状分：圆形膨胀节/矩形膨胀节3、按有无约束分：有约束膨胀节/无约束膨
2、胀节解释：有约束就是膨胀节自身能够吸收内压推力（也叫盲板力），无约束就是膨胀节的内压推力（也叫盲板力）由固定支架来吸收4、按形式分：单式膨胀节/复式膨胀节例如：单式铰链型膨胀节/复式铰链型膨胀节/单式万向铰链型膨胀节/复式万向铰链型膨胀节/复式(大)拉杆型膨胀节/弯管压力平衡型膨胀节/直管压力平衡型膨胀节/旁通直管压力平衡型膨胀节/单式(内压式)轴向型膨胀节/复式自由型膨胀节/外压轴向型膨胀节……leadingrole,strengtheningthecapacityofregionalradiation.Urbanandruralisaninevitable
