Galvanized Steel Pipes: Characteristics, Grades, Zinc Coating and Protection

Galvanized Steel Pipes, which is a pipe material coated with a layer of zinc on the surface of the steel pipe. This layer of zinc is like putting a strong "protective suit" on the steel pipe, giving it excellent anti rust ability. Thanks to its excellent performance, galvanized pipes are widely used in fields such as construction, industry, and agriculture, and are an indispensable foundational material in the development of modern society. Today, we will introduce the characteristics, grades, zinc layer, and protection of galvanized pipes.

The commonly used steel grades for galvanized steel pipes include Q215A, Q215B, Q235A, Q235B, etc. These grades of steel have certain strength and toughness, which can meet the requirements of different scenarios for the use of galvanized pipes. For example, in the construction of scaffolding, Q235 Galvanized Steel Tube are often used, which have good mechanical properties to ensure the stability of the scaffolding and provide a safe working platform for construction personnel.

Galvanized steel pipes are divided into two types: hot-dip galvanizing and electroplating galvanizing. Among them, Hot Dip Galvanized Steel Pipe has a thick galvanized layer, electroplating galvanizing has a low cost, but the surface is not smooth. The thickness of the zinc layer on galvanized pipes is related to their corrosion resistance and service life. The current international and Chinese hot-dip galvanizing standards divide the steel into sections based on its thickness, and stipulate that the average thickness and local thickness of the zinc coating should reach corresponding values to ensure the anti-corrosion performance of the zinc coating. Generally speaking, for pipelines with a wall thickness of greater than or equal to 6mm, the average thickness of the coating is 85 m; For pipelines with a thickness of 3mm

The zinc coating protection of Galvanized Round Steel Pipe [https://www.royalsteelgroup.com/factory-supplier-hot-dip-galvanized-round-steel-pipe-for-construction-product/] is of vital importance, as it is related to their service life and performance. During transportation, storage and installation, avoid collision with sharp objects to prevent scratching the zinc layer. It is also necessary to avoid contact with acidic or alkaline substances, as they can undergo chemical reactions with zinc and erode the zinc coating. During construction, if welding is required, the welding current and temperature must be strictly controlled to prevent the zinc layer from being burned due to excessive current and high temperature. During daily use, regularly clean the dust and dirt on the surface of the Galvanized Iron Pipe to prevent accumulation and the formation of corrosive substances. Once damage to the zinc coating is found, it should be repaired in time. Measures such as applying anti-rust paint or re-galvanizing can be adopted to restore its anti-corrosion performance. At the same time, it is necessary to regularly check whether the connection parts of the Galvanized Steel Pipe are tight to prevent medium leakage due to loosening and accelerate the corrosion of the zinc layer.

By rationally choosing the grade of Hot Dip Galvanized Pipe [https://www.royalsteelgroup.com/high-quality-gi-galvanized-steel-iron-pipe-steel-tube-for-sale-product/], paying attention to the thickness of the zinc coating, and taking good protective measures for the zinc coating, the advantages of Hot Dip Galvanized Steel Pipe can be fully exerted, enabling them to play a stable and long-lasting role in various fields and providing reliable guarantees for production and life.
