API 5CT PSL 1 Stainless Steel Elbow, A403 WP316, Wrought, 8 Inch, 180°.
Seamless elbow: elbow is a pipe fitting used at the bend of a pipe. The largest proportion of all pipe fittings used in the pipeline system is about 80. Usually, different forming processes are selected for bends with different materials or wall thickness. The seamless elbow forming process used by the manufacturer is hot push, stamping, extrusion and so on.
Key points for production
Stainless Steel Bend
1. electrode should be kept dry, Titanium calcium should be dried for 1 hour after 150℃, A low hydrogen type should be dried for 1 hour (not repeated) after 200-250℃, Otherwise, the skin will crack and peel easily), Prevent electrode coating from sticking oil and other dirt, So as not to cause the weld to increase carbon content and affect the quality of welding parts. When the elbow is welded, Precipitated carbides by repeated heating, Reduce corrosion resistance and mechanical properties. After welding hardening is greater, It is easy to produce cracks. If the same type of welding rod is used, Must carry on 300℃ above preheating and after welding 700℃ or so slow cooling treatment. If the weldment can not be heat treated after welding, Chromium nickel stainless steel electrode should be selected. 2. in order to improve the corrosion resistance and weldability of stainless steel elbows, appropriate amount of stability element Ti,Nb,Mo is added, Better weldability, When using the same type of chrome stainless steel electrode, Should carry on 200℃ above preheating and after welding 800℃ or so tempering treatment. If the weldment can not be heat treated, Chromium nickel stainless steel electrode should be selected.
