15CrMo welded steel pipe has the huge market in the future, so it is our mainly product in our company now. We have professional person to produce the 15CrMo welded steel pipe. Of course Katalor aims to supply the high quality 15CrMo welded steel pipe for you.
In view of the some 15CrMo welded steel pipe problems, we should take countermeasures from the following aspects:
1. Preheat before 15CrMo welded steel pipe welding, slow down cooling rate, make weld and nearby hydrogen escape as far as possible, reduce welding stress.
2. Using preheating before welding and controlling interchannel temperature, the reheat crack can be effectively controlled by.
3. In the 15CrMo welded steel pipe welding process, the ultra-low hydrogen R407 electrode and TIGR40 wire should be used to strictly control the content of harmful impurity elements in the weld seam and to reduce the content of Si and Mn.
4. In order to reduce the width and degree of 15CrMo welded steel pipe softening zone, reasonable preheating temperature should be selected before 15CrMo welded steel pipe welding. Reasonable control of interchannel temperature and line energy, heat treatment after normalizing high temperature tempering.
