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. 

Katalor is a professional EN10216-2 16Mo3 pipe supplier and stockist. If you have any need in EN10216-2 16Mo3 pipe, please contact us freely. we will according our stock to delivery EN10216-2 16Mo3 pipe at once. If you want to know more price information, please contact us!

ASTM A517 steel belongs to the boiler steel plate

-
ASTM A517 steel (also called ASME SA517 standard) is a kind of high-strength quenched and tempered alloy steel plates intended for use in fusion welded boilers and other pressure vessels. The steel shall be killed and shall conform to the fine austenitic grain size requirement. Under this specification, the plate thickness determines the grade selection and the mechanical properties.   A517 grade A steel pates 2.5" in thickness and under, will have minimum Yield Strength of 100 ksi.  A517 grade b steel plates over 2.5" in thickness will have a minimum Yield strength of 90 ksi.  Typical applications include unfired vessels and tanks. ASTM A517 Grade A plates are Pressure Vessel Plate and supplied in the as-rolled condition. The ASTM A517 Gr. A plate may be ordered normalized or stress relieved, or both. ASTM A517 Grade H are Pressure Vessel Plate and supplied in the as-rolled condition. The ASTM A517 Gr. H Plate may be ordered normalized or stress relieved, or both. AS

20G boiler steel pipe

Boiler operation status of the GB/T 5310 20G boiler steel pipe  Some steel companies produce the fake 20G boiler steel pipe cause the huge problems. Because the creep resistance of 20G boiler steel pipe is lower than other steel pipes and the 20G boiler steel pipe is overheated, the 20G boiler steel pipe wall metal overheated for a long time, which results in accelerated creep at high temperature, decreased strength, and finally the early creep burst occurred. During 20G boiler steel pipe fracture analysis, it was found that the macroscopic surface of the 20G boiler steel pipe fracture was covered with thin blue-purple oxide film, which indicated that the temperature of the 20G boiler steel pipe burst was 800℃, and the section was not smooth due to the effect of high temperature oxidation. There is a thick oxide layer on the inner surface of the  20G boiler steel pipe . The structure of the oxide layer has three layers and usually only when the ambient temperature

Katalor has more useful S235JR steel plate information S235JR steel plate  is a kind steel grade and it is mainly used for steel structural buildings, frames and other steel body under the standard of EN 10025-2.  S235JR steel plate  is for low temperature impacting test under zero centigree. Katalor steel Industrial specialized in S235JR steel plate  in china many decades years. The composition characteristics of S235JR steel plate  are low carbon, less than 0.20%, low alloy and total alloy element less than 3%. Low carbon content in S235JR steel plate  steel is to meet the technical requirements of plasticity, toughness, weldability and cold deformation of S235JR steel plate  used for engineering structural parts. The S235JR steel plate  has Mn as the main additive and conforms to the resource characteristics of our country. Mn not only has a significant strengthening effect on ferrite , but also reduces the cold and brittle temperature of the S235JR steel plate , and
