When using ASTM A139 steel pipes, it is recommended to consult the specific standard for detailed information regarding the applicable grade, dimensions, and other requirements. Additionally, it is advisable to work with reputable manufacturers or suppliers who can provide pipes that meet the necessary ASTM specifications and quality standards.

Stainless steel square pipes are hollow tubes with a square cross-section that are made from stainless steel. They are commonly used in various industries for applications that require strength, durability, and corrosion resistance.

Here are some key characteristics and features of stainless steel square pipes:

1. Material: Stainless steel square pipes are typically made from austenitic stainless steel, such as grades 304 or 316. These grades are known for their excellent corrosion resistance and mechanical properties.

2. Shape and dimensions: Stainless steel square pipes have a square cross-section, which means all four sides of the pipe have equal dimensions. The size of the pipes can vary, ranging from small dimensions to larger sizes, depending on the application requirements.

3. Strength and durability: Stainless steel square pipes offer high strength and durability, making them suitable for applications where structural integrity is essential. They can withstand heavy loads and pressures without deforming or breaking.

4. Corrosion resistance: One of the primary advantages of stainless steel is its resistance to corrosion. Stainless steel square pipes are highly resistant to rust, oxidation, and staining, even in harsh environments or when exposed to chemicals. This property makes them suitable for outdoor and corrosive applications.

5. Versatility: Stainless steel square pipes find applications in various industries, including construction, architecture, automotive, manufacturing, and more. They are used for structural supports, handrails, frames, furniture, industrial equipment, and piping systems.

6. Weldability: Stainless steel square pipes can be easily welded using common welding techniques, such as TIG (tungsten inert gas) or MIG (metal inert gas) welding. This allows for easy fabrication and customization according to specific project requirements.

7. Surface finish: Stainless steel square pipes are available in different surface finishes, including polished, brushed, or mill finish. The choice of finish depends on the desired aesthetic appearance and the application requirements.

8. Maintenance: Stainless steel square pipes are relatively low maintenance. They are easy to clean, and regular cleaning helps maintain their appearance and corrosion resistance over time.

When purchasing stainless steel square pipes, it's important to consider the specific grade, dimensions, wall thickness, and any additional requirements based on the intended application. Consulting with a supplier or a professional in the field can help ensure you choose the right product for your needs.
