Production process
Raw material preparation:
Select appropriate alloying elements, such as chromium, nickel, manganese, etc., to ensure that it meets the standards of stainless steel.
Smelting:
The raw materials are placed in an electric arc furnace or induction furnace for melting to form stainless steel liquid. The temperature and composition need to be controlled during the melting process to ensure the uniformity of the alloy.
Casting:
Molten stainless steel is poured into a mold and cooled to form an ingot or block.
Hot rolling:
After the ingot is heated to a certain temperature, it is rolled through a hot rolling mill and gradually rolled into the required pipe blank.
Cold rolled or cold drawn:
The tube blank is cold rolled or cold drawn to improve its strength and surface finish to achieve the required tube diameter and wall thickness.
Welding (if applicable):
For seamless pipes, welding is usually not required, whereas for welded pipes, the edges of the pipe blanks are heated and welded together.
Heat treatment:
Heat treatment of the pipe to eliminate internal stress and improve its mechanical properties and corrosion resistance.
Pickling and passivation:
Remove surface oxides and impurities by pickling, followed by passivation to improve corrosion resistance.
.Inspection and testing:
Carry out various inspections on finished products, including size, appearance, mechanical properties and chemical composition, to ensure they meet the standards.
Cutting and Packaging:
Cut the stainless steel pipes into required lengths according to customer needs and pack them for shipment.
