Types of ASTM A789 Stainless Steel Pipe
S32205 Duplex Stainless Steel Pipe
Duplex stainless steel pipe has good welding performance. Compared with ferritic stainless steel and austenitic stainless steel, it does not exhibit the welding heat-affected zone issues seen in ferritic stainless steel, where severe grain coarsening greatly reduces plasticity and toughness.
S31500 Duplex Stainless Steel Pipe
The main feature of duplex stainless steel is that its yield strength can reach 400-550 MPa, which is twice that of ordinary stainless steel. This characteristic allows for material savings and reduced equipment manufacturing costs.
S32760 Duplex Stainless Steel Pipe
Duplex stainless steel refers to stainless steel in which ferrite and austenite each account for about 50%, and generally the content of the lesser phase needs to reach at least 30%. At the same time, it retains the 475°C brittleness and high thermal conductivity of ferritic stainless steel, and has the characteristics of superplasticity.
S31803 Duplex Stainless Steel Pipe
Duplex stainless steel has the characteristics of both austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance.

1. Polishing involves mechanical or chemical processes to smooth the pipe surface, reduce roughness, and enhance aesthetics or functionality.
2. Mechanical polishing: Uses abrasives to grind the surface.
3. Electropolishing: A chemical process that selectively dissolves metal to create a mirror-like finish.
4. Buffing: Uses soft wheels and compounds to refine the surface after grinding.

Industrial Applications of Steel Pipes
Chemical Plants
Line pipes are used to transport various chemicals within industrial plants. They are chosen based on their compatibility with the specific chemicals being transported. For example, in chemical plants that produce acids or bases, line pipes made from corrosion-resistant materials like stainless steel or coated carbon steel are used to prevent chemical reactions that could compromise the integrity of the pipe.
Power Plants
In power plants, line pipes are used to transport water, steam, and other fluids. For example, in thermal power plants, line pipes transport water to boilers and steam to turbines. These pipes must be able to withstand high temperatures and pressures, ensuring the safe and efficient operation of the power plant.
