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.

Dimensional tolerance of ASTM A500 grade C steel tube
When selecting structural steel tubing for construction or industrial applications, precision matters just as much as strength. ASTM A500 Grade C steel tube is widely recognized for its superior yield strength and durability, making it a top choice for structural frameworks, bridges, machinery, and more. However, beyond its mechanical properties, another critical factor must pay close attention to is dimensional tolerance. Accurate dimensions ensure proper fit, structural integrity, and compliance with international standards—helping avoid costly errors during fabrication and installation.
