Product Description
Steel spiral pipes are a vital component in various industries, known for their strength, flexibility, and unique design. These pipes are manufactured using steel strips wound helically and joined through submerged arc welding (SAW). Their robust structure and versatility make them suitable for heavy-duty applications, including fluid and gas transmission.
Key Features of Spiral Pipes
• High Strength: Designed to withstand high pressure due to their spiral structure. • Enhanced Flexibility: Ideal for projects requiring high bending radius. • Customizable Length: Available in various lengths to minimize on-site welding. • Compliance with Global Standards: Manufactured according to API 5L, ASTM A139, and ISO 3183 standards.
Applications
1. Water Transmission: Perfect for municipal and industrial water pipelines. 2. Oil and Gas: Widely used in natural gas and oil transportation lines. 3. Construction: Utilized in bridge-building, foundations, and other civil structures. 4. Industrial Materials Handling: Suitable for chemical and industrial material transportation.
Advantages of Spiral Steel Pipes
• Cost-Effective: Lower production cost compared to longitudinal welded pipes. • High Flexibility: Ideal for projects with curved or variable paths. • Long-Term Durability: Resistant to corrosion and environmental factors with proper coatings. • Ease of Customization: Manufactured to meet precise specifications for specialized applications. At Rosha Steel, we provide high-quality spiral pipes that adhere to international standards, meeting the needs of various industries. These pipes offer a reliable solution for industrial and construction projects globally.
