Do you need to exchange with stainless steel joint or stainless steel pipe joint?If so, 32*3.5 and 34*4.5 should not be chosen.Because the CARDS are metric, and there are series.
2. Weldability
The thickness of welding wall between stainless steel joint and steel pipe determines the difficulty of welding.The thinner the wall, the higher the requirements of the welder, standard stainless steel quick joint if you have the opportunity to see the size of the welded joint weld, the north lun hexagon plug sometimes you find that some of the welding piled up weld is very wide.Standard nozzle universal joint is the level of the welder is not good, no welding will be the steel pipe to burn leak.To make up for the missing.In addition, manual welding is not allowed to directly weld the hydraulic pipeline, also deceive the people of the enterprise just so dry, haigu curved pipe joint on the small caliber of steel pipe is argon arc welding.Large diameter steel tube is argon arc bottom welding cover surface.Some enterprises use electric welding direct welding and then tell the supervision with argon arc strength is not enough.In fact, that is a fraud, are for convenience to do so.
3. The pickling
The welded steel tube must be pickled in order to remove metal impurities such as oxide skin of welding slag inside. At this time, you will find that the welding slag inside electric welding or welding nodules formed during welding are difficult to be pickled away.The flow path of the medium changes, affecting the stability of the system.If working for a long time, the welders will be impacted down into the system, so manual electric welding is not allowed.
4. Wash with oil
After pickling, use working medium or string oil medium, use flushing station to flush the pipeline to make the pipeline meet the technical requirements of accuracy.The time can be long or short, depending on the effect of pickling after welding.
Another method is online pickling
It is the combination of pickling and string oil washing.But the effect is bad, the system with high requirement, pipeline as far as possible do not use this kind of method, it is to fool a person.Another method is to use ordinary pump (not acid resistant pump), using a string of oil medium, which adds a chemical powder.Can both acid wash away dregs, and wash the pipeline, the effect is general.
