With the exploration and innovation of Bebon people, DEN gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel, and established our own Machining processing center in order to meet customer's diverse requirements.




Inconel 625 Tubing Inconel 625 Seamless Tube Inconel

Welded Tube is formed by rolling plate and welding the seam. The weld flash can be removed from the outside or inside surfaces using a scarfing blade. The weld zone can also be heat treated to make the seam less visible.

Heat treating line pipe weld seams The FABRICATOR

Oct 10, 2011 · It is essential to realize that during in line seam heat treatment, the colder part of the pipe acts as a heat sink. Accordingly, the cooling rate is mainly a result of internal heat conduction in the pipe. A properly done weld seam heat treatment ensures a heated zone with the correct normalizing temperatures; that is, with a sufficiently small temperature difference between wall interior

Welding heat treatable steels The FABRICATOR

Mar 14, 2011 · The proper preheat and interpass temperature is usually 400 to 600 degrees F for heat treatable steels. When welding a quench and tempered steel like T1, which has received a heat treatment to achieve a particular strength level, use much lower preheat and interpass temperatures to help control heat input so the designed strength level is

Stabilization Heat Treatment of Austenitic Stainless Steel

Typically the first line of protection is to use an L grade (low carbon) stainless steel and/or filler metal (e.g., Types 304L or 316L stainless steel). Lower carbon, means fewer carbides to deplete the chromium. However, with enough heat or time sensitization can still occur in the L grades.
