How to store galvanized seamless steel pipes?
Galvanized seamless steel pipe is a type of seamless (SMLS) steel pipe coated with a protective layer of zinc. This zinc coating—applied through hot-dip galvanizing or electro-galvanizing—effectively prevents rust and corrosion, while maintaining the high strength, smooth surface, and excellent pressure resistance of seamless steel. This article will briefly introduce how to store galvanized seamless steel pipes.

Differences between galvanized steel pipe and stainless steel pipe
When it comes to choosing the right type of steel pipe for a project, both galvanized steel pipe and stainless steel pipe are strong contenders. Although they may look similar at first glance, they differ greatly in composition, manufacturing process, and application. Understanding these differences is essential for selecting the right material to ensure durability, safety, and cost-effectiveness.

EN 10210 vs Chinese standard steel pipes
In the global steel pipe industry, standard systems from different regions directly shape design, production, and application practices. Among them, the European EN 10210 standard and China’s GB/T series standards (such as GB/T 8162, GB/T 8163, GB/T 6728, etc.) are the two most widely recognized frameworks. Below is a detailed comparison between EN 10210 and GB/T standards from six key aspects.

EN 10220 seamless and welded steel pipes
EN 10220 is a key European Union standard that specifies the dimensions and mass per unit length of seamless and welded steel tubes. Widely used in industrial piping, construction, and mechanical systems, it provides a unified reference for measuring and calculating pipe sizes, tolerances, and theoretical weights. Here's an overview of EN 10220 seamless and welded steel pipes.

Corrosion resistance of galvanized seamless steel pipe
The corrosion resistance of galvanized seamless steel pipe is mainly determined by two factors: the quality and thickness of the zinc coating, and the surrounding corrosive environment. While galvanizing provides reliable protection under normal atmospheric conditions, it is not as durable as stainless steel or advanced anti-corrosion coatings.

Can galvanized pipes be used for gas transmission?
Galvanized pipes (GI pipes) can be used for gas transmission under specific conditions, mainly for low-pressure indoor gas pipelines. However, they must strictly comply with gas pipeline standards and face significant usage restrictions. For outdoor buried pipelines or high-pressure systems, the use of ordinary galvanized pipes is strictly prohibited.

Corrosion resistant galvanized steel pipe
Galvanized steel pipe is a type of steel pipe treated with hot-dip galvanization, where the pipe is immersed in molten zinc. This process forms a protective zinc coating that prevents corrosion, improves durability, and extends the service life of the pipe. Because of these advantages, galvanized steel pipe is widely used in construction, machinery manufacturing, road transportation, water supply systems, and more.

How to prevent rust in GI pipes?
Galvanized pipes are designed with a zinc coating that delays rusting, but once the coating is damaged or consumed, corrosion begins. Effective rust prevention requires a combination of protective strategies, correct installation, and regular maintenance.

Construction technology of galvanized seamless pipe
The construction of galvanized seamless pipes differs from ordinary galvanized pipes, mainly because extra care is needed to protect the zinc layer. Although seamless pipes have no welds, their galvanized coating is soft and easily damaged during cutting, threading, or handling.
