If the wall thickness of the elbow is relatively thick, it is best to perform stress relief heat treatment on the weldment immediately after welding. This is especially true for large-thickness weldments Q235B, high-rigidity structural parts, and weldments that work under severe conditions (dynamic load or impact load). The tempering temperature for stress relief is 600～650℃. For thin-walled elbows, stress heat treatment is not necessary after welding.
The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product RA32 oil supply vessel steel more than 15 years.
For stainless steel plate cutting, the choice of cutting method is determined by the thickness of steel plate. If the thickness of RA32 oil supply vessel steel stainless steel plate is more than 20 mm, flame cutting is adopted, while the thin plate is suitable for plasma cutting. In addition, if the cutting requirements are relatively high, laser cutting can be used. In addition, if the RA32 oil supply vessel steel stainless steel plate is used as a billboard, plasma cutting is adopted, Because it uses thin plates.
