target="_self"><span style="font-size: 16px;">沟槽式管件</span></a>时要选择合适的密封圈。管路中不同的介质要求配备不同材质的密封圈，目前市场上有八种不同材质的密封圈以适用不同的介质。</span></p><p><span style="font-size: 16px;">对不锈钢水管进行沟槽连接，应选用正规厂家的产品，否则在滚槽时易开裂，从而影响密封和使用寿命。管道安装后为了达到良好的密封性，除了选购性能好的沟槽件并保证密封圈无损伤外，安装时密封圈凸缘及外边需要涂一层中性润滑剂，以保证密封圈的唇边和管道密封圈贴合较严密。</span></p><p><span style="font-size: 16px;">管道沟槽(也叫滚槽)是管道连接的关键工艺，也决定<span style="font-size: 16px;"><a href="http://www.masmenosuno.com/gcsgj.html" class='con_kwd'>沟槽式管件</a></span>连接质量的重要环节。沟槽的宽度和深度尺寸需要符合要求。在滚槽时，管口端部应平整，无毛刺，端口应垂直于管子轴线，这样轧出来的沟槽与管子中心轴才能垂直，同时要保证沟槽至管端的长度要均等。若管道的椭圆度和<a href="http://www.masmenosuno.com/bobibxg.html" class='con_kwd'>不锈钢水管</a>壁厚不均，在滚槽时应尽量予以纠正，否则沟槽会产生深浅不均的现象，无法保证它们的严密性。<img src="/UploadFiles/FCK/2020-11/6374129039931991505952762.jpg" title="沟槽卡压式异径接头大小头广东永穗管业品牌.jpg"/></span></p><p><span style="font-size: 16px;">消防水平管若距离较长，采用吊架时，为了打压防止管道窜管，建议中间局部地方使用挠性接头，保证轴向窜管不大，以免影响与它相连的横向支管的弯曲。</span></p><p><span style="font-size: 16px;"><span style="font-size: 16px;">沟槽式管件</span>中的刚性接头、挠性接头的使用要合理。刚性接头适用低压力管道中需要刚性连接的管端使用，如喷淋立管、长距离直线管道、阀门、设备等连接，要求在管路不允许产生位移、转角和扭转的场合使用，以获得良好的刚性。挠性接头适用于中低压力管道连接使用，安装后允许管道有适量收缩、偏角，补偿管道的微量位移，较适用于凹凸不平环境的管道安装；还能吸收噪音、震动，吸纳地震应力，一般应用于消防系统中水泵的进出水管道上。</span></p><p><span style="font-size: 16px;">在有相应温差的场合安装消防管道，管道用固定支架和防晃支架时，可采用挠性接头和刚性接头组合使用，这样打压或温差变化产生的轴向力不会影响横向支管的弯曲。<br/></span></p><p><span style="font-size: 16px;"><img
