The quality inspection of welded steel pipe welding involves not only the assessment of welded joints but also a comprehensive inspection of the entire welding process. This includes pre-welding, in-process, and post-welding stages. A detailed explanation of each phase is provided below.

Plastic-coated straight seam steel pipes produced according to national standards are essential components in modern fire protection systems. Featuring excellent corrosion resistance, high pressure tolerance, and long service life, these pipes are widely utilized in fire water supply networks, sprinkler systems, and other related applications. Here's an overview of national standard plastic-coated straight seam steel pipe for fire protection.

The chemical composition of carbon steel welded pipe varies depending on the grade and application. Here's an overview of carbon steel welded pipe chemical composition.

When choosing the zinc layer thickness for galvanized welded carbon steel pipes, it is essential to consider the environment in which the pipe will be used and the corresponding standards. The thickness of the zinc layer significantly influences the pipe’s corrosion resistance, durability, and overall performance. Below are the international and industry-specific standards, recommended thickness based on usage environments, and considerations for selecting the appropriate zinc layer thickness.

Galvanized ERW pipe (also known as GI ERW pipe) is a welded steel pipe that undergoes a zinc coating process—either hot-dip galvanizing (HDG) or electro-galvanizing (EG)—based on high-frequency electric resistance welded (ERW) pipe. The zinc coating significantly enhances corrosion resistance and extends the service life of the pipe. Among these methods, hot-dip galvanizing is more prevalent, offering a thicker zinc layer and stronger anti-rust performance.

Galvanized welded pipes are steel pipes that have been coated with a layer of zinc to enhance their corrosion resistance and extend their service life. Depending on the galvanizing method and product form, galvanized welded pipes can be divided into several types, each suited for different applications. Below is an overview of the main categories.

Straight seam steel pipes can be categorized into high-frequency straight seam pipes and submerged arc welded (SAW) straight seam pipes based on their production processes. Here's an overview of the production process of straight seam steel pipes.

Carbon steel ERW pipe, short for Electric Resistance Welded pipe, is a tubular product manufactured by joining the longitudinal edges of steel plates or strips through resistance welding. This technique uses electrical current to generate heat at the material edges, achieving a strong, continuous weld without the need for external filler materials. This article will briefly introduce carbon steel ERW pipe production process.
