法兰螺栓对照表
法兰螺栓对照表法兰螺栓对照表1、六角头部类型:一种是平脑的,另一种是凹脑的。
2、表面颜色类别:根据不同需要,表面有镀白、军绿、彩黄、耐腐蚀的达克罗。
3、法兰盘类别:根据法兰螺栓的使用位置不同,盘的大小要求各不相同,另有平底和带齿之分,带齿的起防滑作用。
4、按连接的受力方式,有普通的和有铰制孔用的.铰制孔用的法兰螺栓要和孔的尺寸配合,用在受横向力时。
另外为了满足安装后锁紧的需要,有杆部有孔的,这些孔可以使螺栓受振动时不至松脱.有的法兰螺栓没螺纹的光杆部位要做,叫细杆法兰螺栓.这种法兰螺栓有利于受变力的联结.备注:市场上常用的国标号,GB5789(大头)、GB16674代替GB5787(小头)参考标准GB16674 小系列GB5789 加大法兰系列对应德标DIN EN 1665IF III /ASME B18.2.1 美制系列ASME B2.3.9 公制系列DIN 6921 德国公制系列SAE法兰主要应用于造船,液压机械,矿山机械等行业,来连接各个管路实现管路间液压油的流通SAE法兰的详细信息SAE沉插法兰}JB/ZQ4462-97对焊钢法兰尺寸(PN=10Mpa){sae法兰,SAE分体法兰,SAE对开法兰,SAE对焊法兰,SAE承插法兰,SAE沉插法兰}JB/ZQ4463-97对焊钢法兰尺寸(PN=15Mpa){sae法兰,SAE 分体法兰,SAE对开法兰,SAE对焊法兰,SAE承插法兰,SAE沉插法兰}JB/ZQ4464-97对焊钢法兰尺寸=25Mpa){sae法兰,SAE分体法兰,SAE对开法兰,SAE对焊法兰,SAE承插法兰,SAE沉插法兰} JB/ZQ4465-97对焊钢法兰尺寸(PN=31.5Mpa){sae法兰,SAE 分体法兰,SAE对开法兰,SAE对焊法兰,SAE承插法兰,SAE沉插法兰}JB/ZQ4466-97对焊钢法兰尺寸(PN=40Mpa){sae法兰,SAE 分体法兰,SAE对开法兰,SAE对焊法兰,SAE承插法兰,SAE沉插法兰} JB/ZQ4483-97凸面钢制法兰盖PN=6.3Mpa){sae法兰,SAE 分体法兰,SAE对开法兰,SAE对焊法兰,SAE承插法兰,SAE沉插法兰}JB/ZQ4484-97凸面钢制法兰盖=10Mpa){sae法兰,SAE分体法兰,SAE对开法兰,SAE对焊法兰,SAE承插法兰,SAE沉插法兰}。
