不锈钢三通（ST-6）
不锈钢等径三通:
不锈钢等径三通为管件、管道连接件。用在主管道要分支管处。不锈钢三通有等径和异径之分，等径三通的接管端部均为相同的尺寸；异径的三通的主管接管尺寸相同，而支管的接管尺寸小于主管的接管尺寸。不锈钢三通的液压胀形是通过金属材料的轴向补偿胀出支管的一种成形工艺。其过程是采用专用液压机，将与三通直径相等的管坯内注入液体，通过液压机的两个水平侧缸同步对中运动挤压管坯，管坯受挤压后体积变小，管坯内的液体随管坯体积变小而压力升高，当达到不锈钢三通支管胀出所需要的压力时，金属材料在侧缸和管坯内液体压力的双重作用下沿模具内腔流动而胀出支管。
本公司生产的不锈钢等径等径三通是液压胀形工艺可一次成形，生产效率较高且不锈钢等径三通的主管及肩部壁厚均有增加。因不锈钢等径三通的液压胀形工艺所需的设备吨位较大，本公司生产的无缝三通主要用于小于DN500的标准壁厚不锈钢等径三通的制造。
不锈钢等径三通在报价时,一定要准确告知所使用的管道压力,或直接告知三通壁厚,这样才能报出精准价格,常规表述三通壁厚的有sch10s sch20s等不同的压力等级代表着不同的厚度.可以参照压力等级壁厚表.
不锈钢等径三通用途：石油气管道工程，天然气管道工程，化工厂，电厂，造船厂，制药，乳品，啤酒，饮料，水利等。
