Hot-dip galvanized steel pipe specifications and models

Hot-dip galvanized steel pipe specifications and models refer to the specific size and model identification of hot-dip galvanized steel pipes during the production and sales process. They are crucial to the selection, application, and installation of steel pipes. A hot-dip galvanized steel pipe is a kind of steel pipe that has been hot-dip galvanized. It has the advantages of anti-corrosion and wear resistance and is widely used in construction, transportation, agriculture, and other fields.

1. The meaning of specifications and models of hot-dip galvanized steel pipes.
Hot-dip galvanized steel pipe specifications usually consist of outer diameter, wall thickness, length, and other parameters. Common specifications such as DN15, Φ21.32.77, 6 meters, etc. These numbers and symbols represent the specific size and shape of the steel pipe. Among them, DN15 means a steel pipe with a nominal diameter of 15mm, Φ21.32.77 means a steel pipe with an outer diameter of 21.3mm and a wall thickness of 2.77mm, and 6 meters means that the length of the steel pipe is 6 meters.

2. The importance of specifications and models of hot-dip galvanized steel pipes.
-The specifications and models directly affect the usage scenarios and installation methods of hot-dip galvanized steel pipes. Choosing the appropriate specifications can effectively reduce waste and improve construction efficiency.
- Reasonable specifications and models can ensure the load-bearing capacity and connection stability of the steel pipe, ensuring the safety and stability of the project.

3. Principles for selecting specifications and models of hot-dip galvanized steel pipes.
-Determine the appropriate diameter, wall thickness, and length based on engineering needs to avoid excess or deficiency.
-Choose specifications and models with better corrosion resistance according to environmental requirements.
-Consider the steel pipe connection method and installation requirements, and select specifications and models that meet the standards.

4. Application scope of hot-dip galvanized steel pipe specifications and models.
Hot-dip galvanized steel pipe specifications and models are suitable for various types of building structures, municipal projects, water and gas pipelines, and other fields. In construction, it is often used in stair handrails, railings, bridges, etc.; in the transportation field, it is used in road guardrails, signal brackets, etc.; in agriculture, it is used in greenhouse brackets, water conservancy facilities, etc.

5. How to identify the specifications and models of hot-dip galvanized steel pipes.
The specifications and models of hot-dip galvanized steel pipes are usually marked on the surface of the steel pipe through printing, labeling, engraving, etc. so that users can accurately identify and use them. The logo should be clear, wear-resistant, and not easy to fall off.
