Stainless Steel Square Pipe

Stainless steel square pipe is mainly used in construction, machinery manufacturing, steel construction and other projects. Its production process includes billet preparation, cutting, heating, piercing, rolling, sizing, cooling, straightening, pipe cutting, inspection and storage and other links.

According to the production process, this kind of square pipe can be divided into two kinds: hot-rolled seamless square pipe and cold-drawn seamless square pipe. Its wall thickness can be expressed in both theoretical and actual ways. Because of its excellent corrosion resistance, formability and compatibility, many fields are inseparable from its figure.

Performance Introduction

1. Corrosion resistance: It has good resistance to weak media such as atmosphere, water and steam, as well as organic acids, alkali, salt and other chemical corrosion characteristics. Its surface can form a dense oxide film, effectively prevent the occurrence of rust, especially in the square pipe containing a higher percentage of chromium and nickel, corrosion resistance is more prominent.

2. Heat resistance: In high temperature environment, it has excellent thermal strength and oxidation resistance, can continue to work and maintain good performance.

3. Strength and toughness: It has high strength and toughness. And it can produce an appropriate amount of plastic deformation when stressed, absorb energy, and reduce the possibility of brittle fracture. Its excellent fatigue life makes it suitable for applications that need to withstand periodic changes.

4. Weldability and plastic processing performance: This square tube has excellent welding performance. And it is easy to plastic processing, which makes it highly flexible in the manufacturing process.

5. Aesthetics and economy: The surface of the square tube is smooth and delicate, with shiny luster, beautiful and generous. At the same time, it is also economical and practical, can be recycled and reused, reducing the cost of use.

6. Environmental health: Stainless steel square pipe will not release harmful substances in the production and use process, in line with environmental requirements.

Applications of Stainless Steel Square Pipe

Construction field: This kind of square pipe is very common in the construction field. And it is widely used in indoor and outdoor decoration, screens, stair railings, railings, doors and Windows, kitchen and bathroom. Because of its high strength, corrosion resistance and beautiful features, it has been widely used in the field of construction.

Mechanical manufacturing field: In the field of mechanical manufacturing, it is also an important material. It can manufacture high-demand parts and mechanical equipment, such as power equipment, ships, petrochemical, rail transit and other fields. Its high temperature strength, corrosion resistance, oxidation resistance and other characteristics make stainless steel square pipe indispensable in the field of machinery manufacturing.

Conveying fluid: This kind of square pipe has excellent corrosion resistance and high strength, so it can transport oil, natural gas, water, gas, steam and other fluids.

Public facilities: The construction of public facilities is also inseparable from it, such as stainless steel fences, guardrail, street lights, humanistic decorative landscape.

Automotive mechanical structure: In recent years, with the development of the automotive industry, due to its durability, rust resistance, strong metal texture and other excellent properties, its use in automotive mechanical structure is also growing rapidly.
