304 Stainless Steel Decorative Pipes and Seamless Pipes: What’s the Difference?

Stainless steel has good heat resistance, high-temperature resistance, low-temperature resistance, and even ultra-low-temperature resistance, as well as good corrosion resistance, and has been widely used in various projects. Among them, 304 stainless steel pipes are very popular. Many projects don’t know whether to choose 304 stainless steel decorative pipes or seamless pipes when using them. So what is the difference between 304 stainless steel decorative pipes and seamless pipes?

What’s the Difference between 304 Stainless Steel Decorative Pipes and Seamless Pipes?

1. Weld seam: Stainless steel decorative pipes are basically welded pipes. There will be a weld on the inner wall of the pipe, but seamless pipes are as seamless as its name.
2. Thickness: The wall thickness of stainless steel decorative pipes is uniform, and the inside and outside of the pipes have high gloss. The thickness can be made into thin or thick pipes. However, seamless pipes often have uneven thickness, low gloss, and generally thick wall thickness.
3. Application: Seamless pipes are mainly industrial pipes. Since they are industrial pipes, the surface requirements are not strict and there will be less obvious spots. Decorative pipes are widely used, mainly in the field of decorative welding. However, as the technology of decorative stainless steel pipes becomes better and better, there are also thick-walled decorative pipes that will replace some seamless steel pipes.
4. Surface: The surface treatment requirements of seamless pipes are not strict, while the surface treatment requirements of stainless steel decorative pipes are stricter.

The above is the comparison of the differences between the two from four aspects: weld, thickness, use, and surface.

Advantages of 304 Stainless Steel Decorative Pipes:

304 stainless steel is a very common type of stainless steel, also known as 18/8 stainless steel in the industry. This 18/8 refers to the composition, 18% chromium and 8% nickel. 304 stainless steel is recognized as a food-grade stainless steel by the state. Therefore, 304 stainless steel is the first choice for many home renovations.

304 stainless steel is a versatile stainless steel material with strong rust resistance. It has high temperature resistance and can generally withstand temperatures up to 650℃.

304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance.

For oxidizing acids: In nitric acid with a concentration of ≤65% and a boiling temperature of less than the boiling point, 304 stainless steel has strong corrosion resistance. It also has good corrosion resistance to alkali solutions, organic acids, and inorganic acids.

Advantages of Seamless Steel Pipe:

The advantages of seamless steel pipes are high-pressure resistance, good toughness, long sections with few joints. They are widely used, and domestic steel plants are also very mature in rolling technology.

Compared with round steel, seamless steel pipes have lighter weight at the same strength. The manufacturing of annular parts with seamless steel pipes can improve material utilization rate, simplify manufacturing processes, save materials and processing time, and other advantages.

Compared with welded pipes, seamless steel pipes have no weld on the outer surface. They are transformed from solid round steel to hollow round bars, and have good compressive properties.
