ERW steel pipes are high-strength, durable pipes produced by welding steel strips Longitudinally. They are widely used in various industrial applications thanks to the utilization of sophisticated resistance welding technique, which provides high production efficiency, exceptional savings on cost and materials, as well as dependable performance.
Our ERW round steel pipes are longitudinally welded pipes that are manufactured by forming steel strip into hollow shape, and then welded along the length of the steel pipe. Through the high-frequency electric resistance welding (ERW) process, this type of round steel pipes yields strong joints due to the heat from the electric current can deeply penetrate the metal material.
Our ERW square/rectangular steel tubes are crafted from strip steel through advanced rolling and welding processes. Starting with the unwinding of strip steel, each step, flattening, curling, and welding into round tubes, followed by rolling into square or rectangular shapes, is carefully controlled to ensure precise dimensions.
ERW hot-dip galvanized steel pipes come in two main types: pre-galvanized and hot-dip galvanized. The hot-dip galvanizing process enhances the pipes' corrosion resistance and extends their lifespan, making them a top choice for applications in construction, machinery, bridges, agricultural and oil machinery, and mining industry.
RuiTong Steel offers oil coated ERW steel pipes, a specialized option that undergoes a surface treatment with low-viscosity, environmentally-friendly anti-rust oil. This protective oil coating significantly reduces the risk of corrosion, thereby extending the operational lifespan of the pipes under various environmental conditions.
RuiTong Steel manufactures painted ERW steel pipes that meet the high standards of quality and environmental safety. Using innovative spray equipment and advanced painting techniques, which include precise control of spray distance, pressure, speed, and angle, we ensure our painted pipes offer exceptional thickness, gloss, smoothness, and adhesion.
ERW pre-galvanized steel pipes, also known as mill galvanized pipes, are recognized for their bright, smooth, and aesthetically pleasing appearance. These pipes are coated with a thinner layer of zinc compared to traditional galvanized steel, making them a cost-effective solution for various applications.
At RuiTong Steel, our ERW steel pipes are engineered to form a critical part of building fire safety systems. Constructed from high-strength, low-alloy steels such as Q235B and Q355, these pipes are specially designed to ensure the reliable operation and safety of fire fighting equipment.
Conduit pipe is a widely utilized cable protection device in electrical engineering, designed to secure, protect, and guide electrical wiring. It also functions to reinforce, isolate, and enhance the aesthetic appearance of installations.
We offer welded steel pipes specifically designed for low-pressure fluid transportation. Our range includes both black welded pipes and galvanized welded pipes, tailored for efficient transport of water, gas, air, oil, and heating steam. These pipes are used in systems where fluid pressures are relatively low but require high reliability and consistency.
Hot-dip galvanized welded pipes are a prime choice for greenhouse construction, thanks to their resilient connection stability, high corrosion resistance, and environmental safety. These qualities make them ideal for building materials that ensure the long-term stability and durability of greenhouse structures.
ERW steel pipes are ideal for creating strong, durable, and aesthetically pleasing pipe railings. Known for their well-built construction and ease of installation, these pipes offer an elegant solution for railings while being easy to maintain, ensuring that projects can be completed efficiently without compromising on quality or safety.
Spiral welded steel pipes are extensively utilized as foundational piling pipes in construction due to their simple structure, strong load-bearing capacity, and ease of installation. These attributes make them a preferred choice for various construction projects.
