Jiangsu Gangyu Pipeline Equipment Co., Ltd. is providing robust and reliable basic components for multiple core industrial fields worldwide with its advanced resistance welded (ERW) steel pipe technology. As a professional manufacturer of steel pipes and pipe fittings integrating development, manufacturing, sales and technical services, Gangyu Pipeline emphasizes that its ERW steel pipe products, which combine outstanding craftsmanship, strict quality control and wide application adaptability, have become the preferred choice in many engineering projects.

The modern advantages and application fields of ERW steel pipes

The resistance welding (ERW) process fuses the edges of the steel coil through the heat generated by the current, forming a strong and uniform weld seam. Compared with seamless steel pipes, modern high-frequency ERW steel pipes offer highly competitive cost performance within a specific size range, and they have the advantages of smooth inner walls, high dimensional accuracy, and good concentricity.

The ERW steel pipes produced by Gangyu Pipeline strictly follow international standards and are widely used in:

Building structure and infrastructure: Steel structure pillars for venues, high-rise buildings and Bridges.

Mechanical manufacturing: used for equipment frames, hydraulic systems and drive shafts.

Fluid conveying system: It performs reliably in water supply, heating and low-pressure chemical fluid conveying.

Shipbuilding: Piping systems and structural components used inside the hull.

"At Hongyu, we understand that the piping system is the 'artery' of the entire project," a company spokesperson said. "Therefore, we implement the strictest control standards for every stage of ERW steel pipe production - from raw material selection, forming, welding to final inspection."

Quality assurance: Full-process control from raw materials to finished products

Hongyu Pipeline attributes the outstanding quality of its ERW steel pipes to its systematic quality assurance system:

High-quality raw materials: Select high-quality steel coils to ensure the strength and toughness of the base material.

Advanced manufacturing technology: High-frequency welding technology is adopted to ensure that the strength of the weld seam is comparable to that of the base material. The production line integrates an online weld heat treatment process, effectively eliminating internal stress and enhancing the comprehensive performance of the weld area.

Precision inspection equipment: The company is equipped with a series of advanced inspection equipment, including ultrasonic flaw detectors, hydrostatic testing machines and eddy current testing machines. Each steel pipe has undergone strict testing to ensure it is defect-free and fully meets the pressure rating and dimensional requirements.

Committed to sustainable development and customer success

Adhering to the corporate philosophy of "Quality First, Reputation Supreme", Gangyu Pipeline is not only committed to providing customers with reliable products, but also focuses on the sustainable development of the company. By continuously investing in technological research and development and process optimization, the company strives to enhance product performance while reducing the environmental footprint during the production process.

Our relationship with our clients goes far beyond a single transaction. "We see ourselves as partners in their projects," the spokesperson added. "By providing high-quality ERW steel pipes and comprehensive technical support, we help our clients reduce project risks, ensure the long-term safety and stability of their projects, and thus achieve a win-win situation."
