Advantages of Galvanized Pipe
 

antirust

By providing an extra layer, rust must pass through if rust is contaminated. The iron in steel reacts with oxygen and water and easily causes rust, which leads to deterioration of the object. With a zinc coating, these elements are less likely to cause this reaction.

Lower the price

The galvanizing process is usually less costly than other popular pipe protection methods. This is because other methods usually require a lot of labor, while galvanizing requires less physical labor. At the same time, the service life of galvanized steel pipe is also very long. It can be used for more than 50 years in many rural areas and for more than 25 years in severely exposed urban and coastal environments. As a result, maintenance costs are lower.

Easy to check

The inspection process of galvanized pipe is simple and clear. Galvanized coatings can be visually examined, and their thickness can be tested using a simple nondestructive testing method.

Classification of Galvanized Pipe

 
 

Hot dip galvanized pipe
It is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the in the hot dip bath.

 
 

Cold galvanized pipe
Cold galvanizing is electric galvanizing, and the amount of galvanizing is very small, only 10-50g/m2. Its corrosion resistance is much different than that of hot-dip galvanized pipes. In order to ensure the quality, most regular galvanized pipe manufacturers do not use electro-galvanized (cold plating).

 
 

Hot dip galvanized steel
The steel tube substrate undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a compact structure. The alloy layer is integrated with the pure zinc layer and the steel tube substrate. Therefore, it has strong corrosion resistance.

 
 

Cold galvanized steel pipe
The zinc layer is an electroplating layer, and the zinc layer is independently layered with the steel pipe substrate. The zinc layer is thin, and the zinc layer simply adheres to the steel pipe substrate and is easy to fall off. Therefore, its corrosion resistance is poor.

 

 

 

The Process Flow Of Galvanized Pipe

 

 

Hot-dip galvanizing process

 

Pretreatment

Including degreasing, rust removal (pickling), water washing and plating agent treatment to ensure that the surface of the steel pipe is clean, oil-free and rust-free.

01

Drying and preheating

Heat the treated steel pipe to remove surface moisture and improve the adhesion during zinc dipping.

02

Hot-dip galvanizing

Immerse the steel pipe in high-temperature molten zinc liquid, and the zinc reacts with the steel surface to form a dense zinc-iron alloy layer.

03

Cooling and passivation

The galvanized steel pipe is cooled quickly, and the surface of some products needs to be passivated to increase the resistance to white rust.

04

Inspection and packaging

Carry out coating thickness inspection and appearance quality inspection, and pack and ship after passing the inspection.

05

 

Cold galvanizing process

 
 
01
 

Surface cleaning

Remove oil, rust and other impurities on the surface of the steel pipe by chemical or mechanical means.

 
02
 

Electrogalvanizing

The steel pipe is used as the cathode and placed in an electrolyte containing zinc salts to pass electricity, so that zinc ions are deposited on the surface of the steel pipe to form a thin zinc layer.

 
03
 

Post-treatment and drying

After cleaning and passivation (such as phosphating), it is dried and packaged.

Key Points To Note About Galvanized Pipes

 
Strong anti-corrosion performance

The galvanized layer can effectively prevent metal from corrosion and extend the service life of pipes.

However, the zinc layer of the hot-dip galvanized pipe is closely combined with the steel pipe matrix to form a zinc-iron alloy layer, so it has better corrosion resistance.

Specifications and standards

Galvanized tubes have different nominal wall thicknesses and corresponding weight coefficients. These parameters are formulated according to different usage requirements and standards.

Usage

Galvanized pipes are widely used in water delivery and heating systems in the construction industry, as well as as pipelines for low-pressure fluids such as gas and oil. In addition, it is also used in offshore oil fields, chemical equipment and various industrial structural parts.

 

Application Range of Galvanized Pipe

 

 

First, the field of construction
Galvanized pipes are widely used in the construction field, mainly for indoor and outdoor water, gas, heating and heating projects. In some high-rise buildings, they can also be used as support poles. In addition, galvanized pipe is also an indispensable pipe in public buildings, such as hospitals, schools and docks.

 

Second, electric power engineering
Power engineering towers, high-voltage lines, substations, etc. need to use a lot of galvanized pipe, because galvanized pipe has good electrical conductivity and corrosion resistance. At the same time, galvanized pipe can also be used to manufacture cable protection pipe, wire protection bridge.

 

Third, highway and bridge
In the construction of highway bridges, galvanized pipe is mainly used to protect street lights, signs and other facilities. In addition, the manufacture and repair of some large structures also require the use of galvanized pipe.

 

Fourth, mining engineering
In coal mines, metal mines and other mining projects, galvanized pipe is also a commonly used pipe. With good corrosion resistance and wear resistance, can be used to transport coal, ore and other materials.

 

FAQ

 

Q: What are the advantages of galvanized pipes?

A: Galvanized steel pipes are highly durable and resistant to corrosion, making them suitable for industrial and commercial buildings. These pipes can handle high pressure and are less likely to suffer from leaks or bursts, ensuring a long-lasting plumbing system that requires minimal maintenance.

Q: What's better, copper or galvanized pipe?

A: Due to their toughness and extended lifespan, copper pipes are favored by homeowners. Galvanized pipes don't last as long as copper pipes do, which makes copper pipes a better option for residential and commercial uses. Copper pipes are made in four grades for use in home plumbing installations.

Q: Is galvanized pipe ok for plumbing?

A: Potable water applications: Galvanized pipes, with their zinc coating, are suitable for potable water applications, offering corrosion resistance and longevity. However, it is important to consider potential lead plumbing and the impact of the zinc coating on water quality.

Q: Can I drink water from galvanized pipes?

A: Some leading causes of water contamination in galvanised pipes are lead, iron, zinc, cadmium, and copper. All this makes the water not so safe for drinking.

Q: Will insurance cover replacing galvanized pipes?

A: However, galvanized pipes are obsolete and susceptible to failure with time. Typically, a homeowner's insurance coverage will not cover damages caused by negligence or maintenance difficulties. Most insurers consider it irresponsible for homeowners to keep this type of plumbing in their homes.
