Gi Water Pipe Manufacture Procedures

 

Galvanized water pipes are made of steel or iron and coated with a layer of zinc through a process called galvanizing.

 
01
 

Pickling

Pickling is a method used to remove impurities, oxide scale, rust, and other surface pollutants from the galvanized surface of pipelines.

 
02
 

Hot dipped galvanizing

Immerse the GI tube into a molten zinc bath, keeping the bath at an accurate temperature to ensure appropriate coating thickness and uniformity.

 
03
 

Zinc layer thickness inspection

Non destructive testing methods can be used to measure the thickness of the zinc layer without damaging the pipeline.

FAQ

What are the three types of GI pipe?

In general, GI pipes are classified based on their thickness and durability, which are denoted by different classes.
Light Class (Class A): Light class GI pipes have the thinnest walls and are typically used for light-duty applications such as low-pressure plumbing, irrigation systems, and domestic water supply.
Medium Class (Class B): Medium class GI pipes have thicker walls compared to light class pipes and are suitable for medium-pressure applications such as water distribution, fire protection systems, and industrial piping.
Heavy Class (Class C): Heavy class GI pipes have the thickest walls and are designed for high-pressure and heavy-duty applications such as underground water mains, sewerage systems, and structural support.

Why are water pipes galvanized?

Galvanized pipes are considered safe pipelines for transporting drinking water. Zinc coating is non-toxic and will not leach harmful substances into the water supply, ensuring that drinking water remains clean and safe. Compared to untreated steel or iron pipes, galvanized water pipes are more durable.

Is galvanized steel pipe OK for water?

Yes, galvanized steel pipes are suitable for water supply applications in certain situations. Galvanized steel pipes are coated with a layer of zinc to protect the underlying steel from corrosion, enabling rust prevention and other forms of deterioration.

 

What type of pipe is used for domestic water?

 

 

Common types of pipes used for domestic water supply include:galvanized steel pipes,stainless steel pipes,copper pipes,pvc pipes.
