Is The Wear-resistant Ceramic Elbow Welded Or Flanged?

1: It can be welded, because the wear-resistant ceramic elbow is made of three layers. The first layer is carbon steel, the second layer is a transition layer, and the third layer is ceramics. Then we generally weld on the external carbon steel when welding. The ceramic inside is unaffected!
2: Can it be flanged? The answer is yes, there is no problem in making a wear-resistant elbow and then welding at both ends!
3: Generally, it is better to weld or flange. In fact, the two forms are the same, but the cost is different. If we use flat-welded flanges on both sides, the cost will be high, so some industrial and mining conditions generally use welding!
The answer obtained from the above three items is that ceramic wear-resistant elbows can be welded, and can withstand welding high temperatures of 400°.
