Product Specifications

Galvanizing Process

Hot Dip Zinc Coating

The main production process uses hot-dip galvanizing, where steel pipes are cleaned, acid-pickled, and immersed into molten zinc at approximately 450℃.

During this process, zinc reacts with the steel surface to form a zinc-iron alloy layer and an outer pure zinc protective layer. This structure provides strong coating adhesion and improves resistance against corrosion in outdoor and humid environments.

Compared with ordinary untreated steel pipes, galvanized steel pipes provide longer service life and require less additional surface maintenance.

Anti Corrosion Protection

The zinc coating works through both barrier protection and sacrificial protection.

The external zinc layer blocks direct contact between steel and moisture or oxygen. Even when minor surface damage occurs during transportation or installation, the zinc coating can provide protection by sacrificing itself before the steel substrate is affected.

This makes the product suitable for applications where corrosion resistance and long-term reliability are important.

Material and Structure

Carbon Steel Base with Stable Strength

ZHONGTIAN galvanized pipes use carbon steel as the base material, providing excellent strength, rigidity, and processing performance.

The round tube structure distributes external forces evenly, offering good resistance to compression and bending. The pipes can be cut, welded, bent, and processed according to project requirements.

Multiple Specification Options

Different engineering projects require different pipe dimensions and connection methods. ZHONGTIAN provides various sizes and specifications to meet different installation requirements.

Common material grades include Q195, Q235, Q235B, and Q355B. Standard pipe lengths are available at 6 meters, while customized dimensions can be supplied according to customer requirements.

Connection and Installation

Flexible Installation Methods

ZHONGTIAN Hot Dip Galvanized Round Steel Pipe with Anti Corrosion Coating supports multiple connection methods, including threaded connections, grooved connections, and flange connections.

The standardized dimensions make transportation, installation, and replacement more convenient, helping contractors improve construction efficiency and reduce installation time.

Suitable for Different Engineering Conditions

The product is designed for both indoor and outdoor applications. Its galvanized surface reduces the need for additional painting or coating maintenance, making it a practical choice for projects requiring durable and low-maintenance steel piping solutions.

FAQ

What is the difference between hot dip galvanized pipe and normal steel pipe?

Hot dip galvanized pipe has a zinc protective coating on the steel surface, which improves corrosion resistance and extends service life compared with untreated carbon steel pipes.

How long can galvanized steel pipes last outdoors?

Under normal outdoor conditions, hot-dip galvanized pipes can provide long-term corrosion protection. Actual service life depends on environmental conditions, coating thickness, and installation conditions.

What materials are available?

Common materials include Q195, Q235, Q235B, and Q355B carbon steel grades.

Can you provide customized sizes?

Yes. ZHONGTIAN can supply customized pipe diameters, lengths, surface treatments, and packaging solutions according to customer requirements.

What connection methods are available?

The pipes can be supplied with plain ends, threaded ends, or grooved ends to meet different installation requirements.

Are these pipes suitable for outdoor applications?

Yes. The galvanized coating provides corrosion resistance against moisture and outdoor exposure, making them suitable for many outdoor construction and infrastructure projects.
