159mm straight seam welded pipe - regular specifications in batches, fast delivery
DN159 (i.e. 159mm outer diameter) ERW carbon steel pipe is one of the regular specifications of Huayang Steel Pipe's daily high-frequency production. It is equipped with a special unit for stable operation, sufficient monthly production capacity, and flexible delivery. This specification is suitable for scenes such as urban pipeline networks, machinery manufacturing, structural support, and low-pressure fluid transportation. The wall thickness range covers 3.0mm-10mm, meeting the strength and pressure requirements of different projects. Huayang can provide spot or custom-made, and the appearance and size are fully inspected before leaving the factory.
High-frequency resistance welding process, stable weld quality
Huayang uses high-frequency resistance welding (HFW) technology to heat the edge of the steel strip through high-frequency current and apply extrusion pressure to form a weld. The weld is smooth, without leaks or false welds, and the mechanical properties are basically the same as the parent material. For small and medium-diameter pipes with a diameter of 159mm, the stability of the weld is directly related to the service life and safety of the pipeline. We use multiple inspections such as ultrasonic non-destructive testing and water pressure testing to ensure that each steel pipe meets the factory standards.
Widely used, suitable for a variety of industry scenarios
159mm straight seam welded pipes are widely used in many industries. In municipal engineering, it is often used for water supply, drainage, and fire protection pipelines; in the field of machinery manufacturing, it can be used as a supporting structure and component sleeve; in agricultural irrigation and greenhouse construction, it is also widely used. In addition, it is also one of the common specifications for low-pressure transportation of chemical and natural gas, and has been favored by customers for a long time because of its stable pressure-bearing performance and convenient installation.
