Hot Dipped Galvanized Steel Pipe

TYTSTEEL: your professional galvanized steel pipe manufacturer & supplier

TYTSTEEL is a professional manufacturer of galvanized steel pipes in China. All the pipes are high-frequency welded. You can find galvanized steel pipes in all sizes (custom diameters, thicknesses, lengths) and materials.

There are hot-dip galvanized steel pipes and pre-galvanized steel pipes. We produce both types of galvanized steel pipes according to BS 1387, EN 39, JIS 3444, and ASTM A53/A53M standards. BV or SGS inspection is available if you require.

All of our galvanized steel pipes are tested for mechanical properties after production is completed. The test includes testing the tensile strength, yield strength, elongation, and chemical elements of the galvanized steel pipe to ensure that its mechanical properties meet the standard requirements. It can meet at least 8 hours corrosion free in salt spray test.

hot dipped galvanized pipe Ultimate Guide

hot dip galvanized pipe specification&size

Is hot dip galvanizing better than galvanizing?

Let’s start with the conclusion: I believe that hot dip galvanizing (HDG) is superior to standard galvanized steel.

The main difference between hot-dip galvanizing and regular galvanizing is the method of coating. Hot dip galvanizing involves immersing the steel in a molten zinc solution, while regular galvanizing involves electroplating a layer of zinc on the steel. The hot dipping process creates a thicker layer of zinc on the steel, which remains highly resistant to corrosion even if the pipe is used outdoors or in an environment with high humidity.

Both galvanizing and hot dip galvanizing provide a degree of protection against corrosion, but HDG provides a stronger and longer lasting coating that is better suited for high corrosion applications.

hot dipped galvanized pipe price

The price of hot-dip galvanized steel pipe varies with the raw material, and different parameters such as pipe diameter, length and wall thickness also affect the unit price. You can fill in the form with your needs and we will quote you the latest price within 3 hours.

ls hot dipped galvanized better than stainless steel?

Both hot dip galvanizing (HDG) and stainless steel are effective in preventing corrosion, with HDG being more cost-effective.

Stainless steel is a metal material that is highly resistant to corrosion, mainly due to the formation of a dense oxide film (called a passivation film) on its surface, which theoretically makes it more corrosion-resistant than hot-dip galvanized pipe. But whether it is a stainless steel pipe or a hot dipped galvanized pipe exposed to a harsh environment for a long time, such as strong acids, strong alkalis and other corrosive substances, or subject to mechanical extrusion, friction and other external forces for a long time, corrosion will still occur.
