| 大口径法兰用于法兰与管子的对口焊接，主要使用在焊接技术中，表现良好的使用特点和性能，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，公称压力为0.25～2.5MPa的卷制法兰采用凹凸式密封面。卷制法兰主要应用的环境是适宜的，需要根据具体的情况确定，保证卷制法兰的具体使用价值和性能，承受住高温高压。 Large-caliber flange is used for butt welding of flange and tube. It is mainly used in welding technology. It has good performance and characteristics. Its structure is reasonable, strength and rigidity are large, it can withstand high temperature and high pressure, repeated bending and temperature fluctuation, and its sealing is reliable. Rolled flange with nominal pressure of 0.25-2.5 MPa adopts concave-convex type. Cover. The main application environment of rolled flange is suitable. It needs to be determined according to the specific situation to ensure the specific use value and performance of rolled flange and withstand high temperature and high pressure. 大口径法兰管件焊接时，受到重复加热析出碳化物，降低耐腐蚀性和力学性能。大口径法兰管件，对焊法兰焊条具有良好耐腐蚀性和性，广泛应用于化工、化肥、石油、医疗机械制造。 Carbides are precipitated by repeated heating during welding of large-caliber flanged pipe fittings, which reduces corrosion resistance and mechanical properties. Large caliber flange pipe fittings, butt welding flange electrode has good corrosion resistance and is widely used in chemical industry, fertilizer, petroleum, medical machinery manufacturing. |
