Q235 straight-seam welded steel pipe is made from Q235 steel strip or plate, formed by coiling and then welding. Because it utilizes high-frequency welding technology in its production process, it is also known as high-frequency welded steel pipe. As a representative product of carbon structural ste

First, the Basic Concept and Classification of Seamless Square Steel PipesAs the name suggests, seamless square steel pipes refer to seamless steel pipes with square and rectangular cross-sections. Seamless steel pipes are made by perforating solid round steel and then processing it through processe

The chemical composition of SA-106Gr.C alloy steel pipe is a key factor in determining its performance. Its primary chemical components include carbon, manganese, silicon, phosphorus, and sulfur, and may also contain small amounts of alloying elements such as chromium and molybdenum. The carbon cont

Galvanized steel pipes offer the dual advantages of corrosion resistance and long service life, along with a relatively low price. Therefore, their usage is increasing. However, some users are careless when welding galvanized steel pipes, leading to unnecessary problems. So, what precautions should

Seamless steel pipes coated with paint should comply with the requirements of GB/T8163. Other types of steel pipe should comply with industry standards. The above describes the capabilities and construction requirements of plastic-coated steel pipes. Pay attention to these issues during installation

Seamless steel pipe dimension excess can be categorized into five types: uneven wall thickness, wall thickness excess, outer diameter excess, bend, and length excess.Uneven wall thickness of seamless steel pipe: Uneven wall thickness across the same cross-section of the pipe can occur for a variety

15210 steel pipe, as a key product in the steel industry, has a wide range of uses and diverse manufacturing processes. 15210 steel pipe typically refers to a steel pipe with a diameter of 15 mm and a wall thickness of 2 mm, typically made of carbon steel or alloy steel. This type of steel pipe play

Stainless steel pipes rely on a very thin, strong, dense, and stable chromium-rich oxide film (protective film) formed on their surface to prevent further oxygen infiltration and oxidation, thus achieving their rust resistance. If this film is continuously damaged for some reason, oxygen atoms from

First: Causes of Alkali Reversion (White Rust, Black Spots)1. Principle of White Rust Formation on Galvanized Steel Sheets: When galvanized steel sheets are densely packed and placed in humid air, without free air flow across the surface, electrochemical corrosion of the zinc layer occurs, resulting

In the steel plate business, many people often encounter these types of products, and some are confused about the differences: Is pickling considered cold rolling or hot rolling? Is cold forming considered cold rolling or hot rolling? Are hard rolling and cold rolling the same? These are soul-search
