Stainless Steel Square Pipe

Stainless steel square tube is a hollow tube with a square cross-section and is made of stainless steel. Stainless steel square tubes are manufactured using various processes such as hot rolling, cold rolling or extrusion according to the required size and specifications.

They are available in a variety of sizes, thicknesses and grades to meet different industry needs. For example, 304, 316, etc. are all commonly used grades of stainless steel. The main material of stainless steel square pipe gives it excellent corrosion resistance. Plus, they are extremely durable and can withstand high pressures, extreme temperatures, without deforming.

Gnee has the widest range of square tubes available in stock. Here are a variety of lengths, widths, and thicknesses to choose from. In addition, we provide test certificates and processing services. We have our own factory and can supply steel pipes in large quantities at factory prices.

Stainless steel square pipes are highly resistant to corrosion and oxidation. They contain a minimum of 10.5% chromium, which forms a protective passive layer on the surface, preventing rust and corrosion even in harsh environments. This makes them suitable for outdoor and marine applications.

Stainless steel square pipes are known for their exceptional strength and durability. They can withstand high pressure, heavy loads, and extreme temperatures without deformation or structural damage. This makes them suitable for structural applications in construction, architecture, and industrial settings.

Stainless steel square pipes can be easily welded, ensuring strong and secure joints. This enables seamless construction and facilitates the fabrication of complex structures.

Stainless steel retains its strength and integrity even at high temperatures. It exhibits excellent thermal conductivity, making it suitable for applications involving heat transfer or exposure to elevated temperatures.

FAQS

Stainless steel square pipes are available in various sizes, ranging from small dimensions suitable for decorative purposes to larger sizes used in structural and industrial applications. Common sizes include 1/2 inch, 3/4 inch, 1 inch, and larger, with different wall thicknesses to accommodate specific requirements.

Stainless steel square pipes are typically manufactured using the same processes as round stainless steel pipes, such as seamless or welded methods. The square shape is achieved by shaping the steel into a square cross-section during the manufacturing process.

Similar to round stainless steel pipes, square pipes are available in various grades, including 304, 316, 409, and others. The choice of grade depends on factors such as corrosion resistance, strength, and cost, as well as the specific requirements of the application.

Yes, stainless steel square pipes can be customized to meet specific requirements in terms of size, length, wall thickness, finish, and other parameters. Custom fabrication services are available to tailor square pipes to the needs of individual projects or applications.

Yes, stainless steel square pipes are suitable for outdoor applications due to their excellent corrosion resistance. They are commonly used in outdoor structures, such as railings, fences, and architectural features, where exposure to harsh weather conditions is a concern.

What Services Does Gnee Provide?

Gnee can provide the following measurement services for pipe:

1. Dimensional measurement: Measure the dimensional parameters such as length, width, and thickness by measuring instruments to ensure the pipe is qualified and meets the design requirements.
2. Surface measurement: Measure parameters such as flatness, unevenness, and surface roughness of pipe surface to help ensure that the quality and surface state of the pipe meet the requirements.
3. Thickness measurement: Use a thickness measuring instrument to accurately measure the thickness of the pipe to ensure that it meets the design requirements.
4. Material measurement: Use material analysis instruments to measure the chemical composition and mechanical properties of the product to ensure that the quality and performance meet the requirements.
5. Bending and Deformation Measurements: The degree of bending and deformation of the steel pipe is measured and monitored by using tools such as bending measuring instruments and displacement sensors to ensure that it is within the allowable range.

Ask Measurement service

Gnee can customize the size and shape of steel pipes for your project according to specific project needs. The custom design of the pipe is carried out by a professional engineer and design team. Based on the requirements and constraints of the project, they will use calculation and simulation tools, combined with experience and technical knowledge, to optimize the steel pipe design to meet the specific needs of your engineering.

● According to the strength requirements of structural design, adjust the thickness, width, and length of pipes.
