Galvanized Oval Steel Pipe

Xinlida Steel Pipe's galvanized oval steel pipes use ordinary carbon structural steel or low-alloy structural steel round pipes as the base material, forming a uniform and dense zinc layer on the inner and outer surfaces of the pipe through hot-dip galvanizing or electro-galvanizing processes. Its core function is to provide long-term corrosion protection for the base material through the sacrificial anode protection effect of the zinc layer, while retaining the basic performance of the round pipe in terms of pressure bearing, material conveying, and structural support. This product can be widely used in fluid transportation, structural support, frame construction, and other fields, suitable for various indoor and outdoor environments, and especially suitable for humid and highly corrosive conditions.

This product has five core advantages:

1. The zinc coating bonds tightly to the substrate, forming a double protective barrier that effectively prevents corrosion and extends service life to 20-30 years (depending on the usage environment), significantly reducing subsequent maintenance costs.

2. The substrate is made of high-quality steel, processed through multiple steps, resulting in excellent pressure strength, bending strength, and impact resistance.

3. It boasts excellent structural stability; its smooth surface is suitable for various connection methods such as welding and flange connections.

4. It is lighter than solid steel of the same specifications, facilitating handling and installation, and improving construction efficiency; compared with stainless steel pipes and other anti-corrosion pipes, its production cost is lower, achieving a balance between low cost and high durability.

5. Utilizing an environmentally friendly galvanizing process, it ensures that the zinc coating meets national standards and does not contain excessive harmful heavy metals, making it suitable for drinking water transportation, etc.

Application scenarios: Abandoned pipes can be recycled and reused, which is in line with the concept of green development.

Product application scenarios

Application Scenarios: Urban water supply and drainage pipelines, natural gas transmission pipelines, municipal greening fences, street light pole supports, underground pipeline corridor supports, etc.

Case Study: A water supply and drainage pipeline renovation project in the old city area of a provincial capital city selected DN100-DN300 hot-dip galvanized round pipes as the main water transmission pipelines, with a total laying length of 28 kilometers. Thanks to their excellent corrosion resistance and adaptability to humid underground environments, the project effectively solved the problems of rust and leakage in the original pipelines, ensuring the safety of residents' water supply.

Construction Engineering Field

Application Scenarios: Main structure support construction, scaffolding erection, fire protection pipe installation, air conditioning and ventilation duct laying, roof drainage pipe installation, etc.

Case Study: A large commercial complex construction project used galvanized circular pipes ranging from DN50 to DN200 for the construction of a fire sprinkler system and scaffolding support system. The total weight of the pipes used exceeded 1,500 tons. This solution not only met the corrosion resistance and pressure resistance requirements of the fire protection pipes but also ensured the structural stability of the scaffolding. The project successfully passed fire safety and engineering quality acceptance.

New energy fieldApplication Scenarios: Photovoltaic power station brackets, auxiliary support structures for wind turbine towers, and frames for new energy charging piles, etc.

Case Study: A large-scale centralized photovoltaic power station project used φ48 × 3.0 hot-dip galvanized round tubes to manufacture photovoltaic module brackets, with a total output exceeding 800 tons. This bracket is suitable for outdoor, windy, and sandy environments. The zinc coating effectively resists ultraviolet radiation and wind and sand erosion, thus ensuring the service life of the bracket and the installation stability of the photovoltaic modules.Agricultural sector

Application Scenarios: Greenhouse frames, farmland irrigation pipes, livestock shed construction, etc.

Case Study: A greenhouse construction project in a modern agricultural industrial park used galvanized round pipes of φ25 × 2.0 and φ32 × 2.5 specifications to construct the greenhouse frames, resulting in the construction of 50 standardized greenhouses. These pipes are lightweight, corrosion-resistant, suitable for the high humidity environment inside greenhouses, and have good load-bearing capacity, supporting the installation of insulation film and shade netting.
