Manufacturing Process of ASTM A335 P22 Pipes

ASTM A335 P22 Pipe is produced in seven steps. It manufactures a wide range of shapes, goods, and parts, ranging from ASTM A335 P22 Pipe and Coil.

• Step 1 : Raw Material Selection
  To begin the process of creating ASTM A335 P22, raw materials such as iron ore and other elements including nickel, chromium, and molybdenum are carefully selected. The choice of alloying elements depends on the specific properties that the ASTM A335 P22 is intended to possess.
• Step 2 : Smelting and Melting
  Once the raw materials have been selected, they are smelted in a furnace to create a molten metal alloy. The composition of the alloy is closely monitored and controlled to achieve the desired grade of ASTM A335 P22.
• Step 3 : Forming
  After the molten ASTM A335 P22 has been produced, it is cast into different shapes and forms, depending on its intended use. The most common shapes include slabs, billets, blooms, or ingots.
• Step 4 : Primary & Secondary Steelmaking
  The subsequent step is primary steelmaking, which can be accomplished through different methods such as the Basic Oxygen Furnace (BOF) or the Electric Arc Furnace (EAF). At this stage, impurities like carbon are eliminated to achieve the desired chemical composition.
• Step 5 : Casting
  The molten ASTM A335 P22 is then cast into semi-finished forms, which can take the shape of plates, sheets, bars, or other forms. Continuous casting or ingot casting methods are usually employed for this purpose.
• Step 6 : Hot Rolling
  In the case of products like ASTM A335 P22 Pipes, the semi-finished castings are hot-rolled to achieve the desired thickness and shape. During this process, the thickness of the castings is reduced while improving their mechanical properties.
• Step 7 : Cold Rolling and Annealing
  In the case of specific ASTM A335 P22 products such as thin sheets and coils, cold rolling is employed to further reduce the thickness and enhance surface finish. To relieve stresses and enhance corrosion resistance, annealing is frequently performed.
