Adhering to National Standards, Quality Guaranteed
Huayang Steel Pipe manufactures ERW GB/T 3091 carbon steel pipes, widely used in urban water supply, gas, and low-pressure fluid transportation projects. This standard is the main standard for welded steel pipes used in fluid transportation in China, with clear requirements for chemical composition, mechanical properties, and weld quality. Huayang selects high-quality Q235B or Q345B hot-rolled strip steel as raw material, employing precise forming and high-frequency welding processes to ensure that the products meet the pressure resistance and corrosion resistance requirements under the GB/T 3091 standard.
219mm Specification, Balancing Strength and Economy
Φ219mm is a commonly used specification in Huayang's export and domestic projects, with a wall thickness generally ranging from 6mm to 10mm. This size of steel pipe can meet the needs of medium-flow water and gas transportation while offering good installation flexibility, and is widely used in urban main pipelines, factory water supply trunk lines, and natural gas pressure regulating station external pipeline networks. Huayang's production lines utilize automated online weld flaw detection and hydrostatic testing equipment. Every Φ219 steel pipe undergoes 100% inspection to ensure uniform pipe body, dense welds, and no leakage.
Double Corrosion Protection, Adaptable to Diverse Operating Environments
For the specific characteristics of water and gas transmission projects, Huayang offers internal and external anti-corrosion treatment solutions, including hot-dip galvanizing, epoxy coating, or 3PE anti-corrosion layer. The anti-corrosion layer effectively improves the corrosion resistance and service life of the steel pipe, allowing for stable operation for over 20 years in humid, buried, and coastal environments. Simultaneously, the smooth high-frequency weld seam on the outer wall reduces fluid resistance and improves transmission efficiency, making it particularly suitable for water supply and gas grid connection projects.
Huayang Manufacturing, Making Urban Transmission Safer
As a leading straight seam welded pipe manufacturer in Hebei Province, Huayang Steel Pipe boasts over 40 automated ERW production lines and an annual manufacturing capacity of 2.6 million tons. Its products are widely used in domestic and international municipal engineering projects, gas groups, and large-scale water projects. The 219mm GB/T 3091 carbon steel pipe is a typical example of Huayang's "winning trust with quality". Every steel pipe leaving the factory has complete test data recorded, providing a solid safety guarantee for urban infrastructure and making the transportation of water and energy more reliable, long-lasting and efficient.
