Shunde Longyao Steel Co., Ltd. in Foshan was established on May 11, 2015. The legal representative is Huang Songming, and the company is engaged in the sale of steel and domestic commerce.
The characteristics of spiral steel pipes mainly include the following aspects:
High strength: Spiral steel pipes are made by welding high-strength steel plates, offering high strength and toughness, capable of withstanding significant internal and external pressures. Excellent welding performance: Produced using continuous welding methods, the seams of spiral steel pipes have high quality, ensuring strength and sealing at the welds. Moreover, the seams have high quality, the main stress is hoop stress, the spiral seam angles at 45 degrees to the axis, avoiding the main stress, while the main stress of straight seam pipes is perpendicular to the weld. Strong adaptability: Spiral steel pipes can be produced in various diameters, wall thicknesses, lengths, and materials to meet engineering needs and conditions. Easy and quick construction: The diameter and length of spiral steel pipes can be adjusted as needed to meet different construction requirements. Additionally, the installation process is mature, allowing both manual and mechanical construction with rapid work progress. Competitive cost: The mature production process of spiral steel pipes allows the use of the same width steel strip to produce pipes of different diameters, with adjustable forming and interchangeable specifications for easy mass production, achieving mechanization, automation, and continuous production. Therefore, spiral steel pipes are relatively inexpensive with low overall cost. Smooth tube wall: The smooth tube wall of spiral steel pipes enhances transport efficiency. Large diameter specifications: The specifications of spiral seam weld pipes range from Φ219-1420mm, even up to 3860mm. Excellent corrosion resistance: Spiral steel pipes have strong corrosion resistance, capable of withstanding corrosion from various chemicals. Water vapor resistance: The seams of spiral steel pipes are焊接 using spiral submerged arc welding technology, ensuring the sealing of the seams and preventing water vapor penetration. In summary, spiral steel pipes possess multiple excellent features like high strength, good welding performance, strong adaptability, easy construction, low overall cost, smooth tube wall, large diameter specifications, strong corrosion resistance, and water vapor resistance, making them widely used in various engineering fields.

Common spiral steel pipe outside diameters include 219mm, 325mm, 406mm, 508mm, 610mm, 711mm, 800mm, 820mm, 850mm, 914mm, 1000mm, 1020mm, 1200mm, 1220mm, 1420mm, 1520mm, 1680mm, and 1800mm.
These spiral steel pipes with varying outer diameters are widely used in industrial and municipal engineering fields, such as water supply and drainage projects, sewage treatment plants, and water conservancy projects. Different outer diameters of spiral steel pipes can be selected to meet the actual engineering requirements.
