产品简介：
丝扣法兰:适用于公称压力不超过2.5MPa的钢管道连接.丝扣法兰的密封面可以制成光滑式,凹凸式和榫槽式三种.光滑式丝扣法兰的应用量最大.丝扣法兰多用于介质条件比较缓和的情况下，如低压非净化压缩空气、低压循环水，它的优点是价格比较便宜
丝扣法兰:用于法兰与管子的对口焊接,其结构合理,强度与刚度较大,经得起高温高压及反复弯曲和温度波动,密封性可靠丝扣法兰.
公称压力为0.25～2.5MPa的丝扣法兰采用凹凸式密封面.板式螺纹法兰采用内孔管螺纹加工，应使钢管拧紧后的端部靠近但不超出法兰密封面。在工程建设中比较常用，安装方便，不需焊接。
法兰适用标准：化工部HG20601-1997，化工部HG20622-1997、国标GB/T9123.1-2000—GB/T9123.4-2000。
注：可定做各种材质非标法兰
