Embodiment Construction
[0032] Attached below Figure 1-2 The present invention is described further:
[0033] With reference to accompanying drawing: the production technology of a kind of sanitary grade stainless steel pipe in the present embodiment, comprises the following steps,
[0034] (1) Forming welding: Send the uncoiled stainless steel to the forming machine; weld the gaps of the formed stainless steel pipes, and use protective gas to cool them during welding; use a grinder to trim the outer surface welds of the welded stainless steel pipes flat;
[0035] (2) Solution annealing: Push the stainless steel pipe after leveling the weld seam into a continuous heating furnace for heating at a temperature of 120°C, then perform non-oxidative heat treatment in a heat treatment furnace at a temperature of 1050°C, and cool it when it comes out of the furnace. The water jacket cools the finished stainless steel pipe, and the outlet temperature of the finished stainless steel pipe is 32°C--38°C;
