EN10216-2 16Mo3 pipe

Three problems in the welding process EN10216-2 16Mo3 pipe need to be careful



EN10216-2 16Mo3 pipe is belong to pipe for pressure purposes, and it is mainly product in Katalor. We can supply EN10216-2 16Mo3 pipe with good quality according your require. But there are also some points in EN10216-2 16Mo3 pipe have to be careful.
In the welding process of EN10216-2 16Mo3 pipe, the main problems are as follows: 


First, it is easy to produce welding cold crack. The hardening property of steel depends on its carbon content. The alloy composition and content of EN10216-2 16Mo3 pipe contain more carbon and alloy elements, and the hardening sensitivity is greater. The alloying elements Cr and Mo delay the transformation of EN10216-2 16Mo3 pipe during cooling process. The stability of undercooled austenite is improved and the hardening property of steel is improved obviously.


Second, the EN10216-2 16Mo3 pipe still has the tendency of reheat crack, and long time brittle change caused by diffusion segregation of trace elements such as phosphorus along grain boundary.

Third, if customer use EN10216-2 16Mo3 pipe to produce the water wall structure of gasifier, it is complicated. The water wall tube is only 230 mm from the inner furnace wall, the tube arrangement is dense, the welding area is narrow, so the welding is difficult.

Finally, Because the combustion chamber of the gasifier operates at higher temperature and pressure, the weld seam of the EN10216-2 16Mo3 pipe is required to be high, and 100%RT detection is needed.
