Can be welded together. However, three factors should be considered:
1. Whether the wall thickness and staggered edge of the two pipelines meet the welding requirements.
2. Correct treatment of groove: grinding to a certain slope according to requirements, and removing galvanizing and rust within 5 mm of welding edge.
3、这两种管道是否均契合介质运用要求。 一般情况下碳钢管道与镀锌管道是不衔接在一起的,假如需要衔接在一起,应用阀门进行衔接。 镀锌管能够焊接。包含无缝钢管+热镀锌变成的镀锌无缝钢管和一般的镀锌焊接钢管;在国标和国内监理标准中,镀锌钢管要焊接确实。 是能够的,可是同楼上所说运用条件和耐压等级同镀锌管一样 特别工况下要求必须直接焊接时采纳必要的处理工艺是能够焊接的。但尽量防止。最好是采纳法兰衔接。
3. Whether the two pipelines meet the requirements of medium operation. Generally speaking, carbon steel pipe and galvanized pipe are not joined together, if need be joined together, the application of valves for joining. Galvanized pipe can be welded. Including seamless steel pipe + galvanized seamless steel pipe and galvanized welded steel pipe; in national standards and domestic supervision standards, galvanized steel pipe should be welded really. Yes, but it can be welded by adopting the necessary processing technology when direct welding is required under the same special working conditions as galvanized pipes. But try to prevent it. It is better to adopt flange connection.
碳钢管能够与镀锌管焊接,一般可用于辅助管线,如冷却水管道,压缩空气管道等。 镀锌管在焊接后表皮会不会氧化的很厉害,相当是退火了,质量会不会有太大影响,套丝好还是,没见有接的 赞同二楼的意见,钢管与镀锌管用缧纹或法兰衔接,镀锌管焊接后,会把镀锌层损坏,影响其防腐效果. 能够焊接在一起,但只用于辅助管线,如冷却水管道,压缩空气管道等 感觉用法兰衔接好点,镀锌的焊接不太好。
Carbon steel pipes can be welded with galvanized pipes, which can be generally used for auxiliary pipes, such as cooling pipes, compressed air pipes, etc. Galvanized pipes will oxidize badly after welding, rather annealed, the quality will not have a great impact, the sleeve is good or not, there is no agreement with the second floor opinion, steel pipes and galvanized pipes with stripes or flanges, galvanized pipes after welding, galvanized layer will be damaged, affecting its anti-corrosion effect. Can be welded together, but only for auxiliary pipes, such as cooling pipes, compressed air pipes. Dow and so on feel good with flange connection point, galvanized welding is not very good.
