Q355B material offers high strength and toughness.
Q355B is a low-alloy, high-strength structural steel with excellent yield strength (minimum 355 MPa), impact toughness, and weldability, making it suitable for pressure-bearing structures and welded components. Huayang Steel Pipe uses raw sheet steel from large steel mills to produce Q355B carbon steel pipe. This material is stable and uniform in composition, ensuring that project requirements for strength, weather resistance, and safety are met from the source. This material is commonly used in industrial pipelines, steel structure projects, and medium- and high-pressure fluid transportation projects.
HFW high-frequency welding technology provides dense and uniform welds.
Q355B HFW carbon steel pipe utilizes high-frequency resistance welding technology. The edges of the steel strip are heated by high-frequency current and then press-welded. No filler material is required, and the weld is as strong as the parent material. Huayang has introduced a fully automatic online monitoring system for real-time control of welding temperature and pressure. It also utilizes processes such as eddy current testing, hydrostatic testing, laser caliper measurement, and manual spot checks to ensure that each steel pipe weld is stable, dimensionally accurate, and leak-resistant, making it suitable for applications requiring high weld strength.
It is widely used in projects such as structural pipe networks and energy projects.
Q355B HFW welded pipe has proven applications in a variety of fields, including urban drainage, power plant pipe networks, bridge steel structures, plant frames, and port support piles. For example, in a water supply renovation project at a thermal power plant in Hunan, Huayang supplied Q355B HFW pipe for high-temperature hot water mains. In a natural gas branch pipeline project in Central Asia, the client specified Q355B material to enhance overall system strength and durability. In actual use, it has demonstrated excellent construction adaptability and operational stability.
As a factory with an annual production capacity of 2.6 million tons, Huayang Steel Pipe consistently exports Q355B HFW carbon steel pipe to the Middle East, Africa, Southeast Asia, and other regions. We offer one-stop processing services, including custom-length production, beveling, marking, capping, and 3PE/2PE/painting for corrosion protection. We also assist in providing export documentation such as third-party inspection reports, English warranties, and packing lists. Our in-house quality control and production scheduling systems ensure that every order is delivered on time and to the highest quality standards.
