The production of galvanized ERW pipe involves two main stages: the formation of the pipe using electric resistance welding and the application of a protective zinc coating through galvanization. Each stage is critical to ensuring the final product offers both structural integrity and long-lasting corrosion resistance. Below is a breakdown of the process

Galvanized ERW (Electric Resistance Welded) pipe is a type of steel pipe that combines the high-efficiency forming and welding process of ERW technology with the corrosion resistance provided by galvanization. Manufactured from hot-rolled or cold-rolled steel strips, the material is first formed into a tube and then welded using high-frequency resistance welding. After welding, the pipe is galvanized—either by hot-dip or electroplating—to enhance its durability and corrosion resistance. This product plays a vital role in various industries due to its structural strength, low cost, and extended service life.

In modern steel structure engineering, efficiency, strength, and adaptability are key. Among various types of steel pipes, Electric Resistance Welded (ERW) pipes stand out for their excellent performance and cost-effectiveness, making them a widely used material in applications such as scaffolding, steel frames, bridge supports, and large architectural facilities.

Welded steel pipes play a critical role in modern engineering, from transporting oil and gas to supporting large-scale infrastructure projects. Their widespread use depends not only on performance but also on stringent quality control throughout the manufacturing process. This article outlines the essential quality assurance practices and common application areas of welded steel pipes.
