Types of Rectangular Steel Pipes and Their Applications
1. Rectangular Welded Steel Pipes
Rectangular welded steel pipes are manufactured by welding hot-rolled or cold-rolled steel strips into a rectangular cross-section. These pipes are cost-effective and easy to produce, making them a popular choice in multiple industries.
Key Features:
Simple manufacturing process, reducing production costs.
Smooth surface and precise dimensions, ensuring easy installation.
Strong load-bearing capacity, making them suitable for construction and machinery manufacturing.
Applications:
Building structures
Machinery manufacturing
Bridge construction
2. Rectangular Galvanized Steel Pipes
Rectangular galvanized steel pipes are produced by applying a hot-dip galvanizing process to welded steel pipes. The zinc coating effectively prevents oxidation and corrosion, enhancing durability.
Key Features:
Corrosion-resistant zinc coating extends service life.
Bright appearance with some decorative properties.
Low maintenance and long-term durability.
Applications:
Petroleum and chemical industries
Water and gas supply systems
Infrastructure projects requiring corrosion resistance
3. Rectangular Seamless Steel Pipes
Rectangular seamless steel pipes are made from solid billets through heating, perforation, rolling, and shaping processes. Compared to welded pipes, seamless pipes have higher strength and superior load-bearing capacity.
Key Features:
High tensile strength, suitable for heavy-load applications.
Smooth inner and outer surfaces for efficient fluid transport.
Precision manufacturing ensures uniformity and reliability.
Applications:
High-pressure equipment
Oil exploration and geological industries
Shipbuilding and marine applications
4. Rectangular Stainless Steel Pipes
Rectangular stainless steel pipes are manufactured using corrosion-resistant stainless steel, making them highly durable and visually appealing.
Key Features:
Strong corrosion resistance, eliminating the need for additional coatings.
Aesthetic appearance suitable for architectural and decorative applications.
Resistant to harsh environments, including marine and chemical exposure.
Applications:
Architectural decoration
Food processing and sanitary equipment
Marine engineering and chemical processing
