ASTM a270 321 Sanitary silk Mirror Matte surface Stainless Steel Welded Tube for dairy product process

Stainless steel welded pipe is a crucial component in various industries, known for its durability, corrosion resistance, and versatility. This type of pipe is manufactured by welding together two or more pieces of stainless steel, creating a strong and seamless connection. Unlike its counterpart, the seamless pipe, welded pipe offers unique advantages in terms of cost-effectiveness and dimensional consistency.

Benefits of Stainless Steel Welded Pipe

The advantages of using stainless steel welded pipes include:
 
A. Excellent corrosion resistance: This property ensures the longevity and integrity of piping systems in various environments.
 
B. High strength-to-weight ratio: Stainless steel welded pipes offer robust performance without excessive weight.
 
C. Resistance to high temperatures and pressures: This makes them suitable for demanding industrial applications.
 
D. Aesthetic appeal: Their polished appearance makes them attractive for visible installations.
 
E. Cost-effectiveness: Compared to seamless pipes, welded pipes are generally more affordable, offering a balance between performance and cost.

 

Maintenance and Care

To ensure the longevity of stainless steel welded pipes:
 
A. Regular cleaning procedures: Implement routine cleaning to maintain the pipe's appearance and performance.
 
B. Avoiding harsh chemicals and abrasive materials: Use appropriate cleaning agents to prevent damage to the pipe's surface.
 
C. Proper drainage: Ensure systems are designed to prevent water stagnation, which can lead to corrosion.
 
D. Inspection and replacement schedules: Regularly inspect pipes for signs of wear or damage, and replace as necessary.

5. Can we visit your factory?
--Warmly welcome. Once we have your schedule, we will arrange the professional sales team to follow up your case.

6.How to distinguish 304 and 201 stainless steel?
--1). Specification: the Bai composition is different. 304 has better quality  and the price is expensive, but 201 is worse. 304 is imported stainless steel plate and 201 is domestic stainless steel plate.
2). 201 is composed of 17cr-4.5ni-6mn-n which is used for railway vehicles.While 304 is composed of 18cr-9ni, which is used for food production equipment, Xitong chemical equipment, nuclear energy, etc.
3). 201 has high manganese content, bright surface with dark brightness, high manganese content and easy to rust. 304 contains more chromium, the surface is matte and does not rust .The most important thing is that the corrosion resistance is different. The 201 corrosion resistance is not as good as that of 304.
4). The difference between 201 and 304 is the problem of nickel. The 304 nickel's content is more than 201.
5). Stainless steel is not easy to rust because chromium rich oxide is formed on the surface of the steel body to protect the steel body. Material 201 belongs to high manganese stainless steel, which has higher hardness, high carbon and low nickel than 304.
