Comparison: Galvanized Pipe vs. Stainless Steel Pipe
Which Pipe Bears Weight Better?
A common question is asked:
Is a galvanized pipe or a stainless steel pipe better for bearing weight?
Some people say galvanized pipes are cheaper.
However, it is not clear if they work as well as stainless steel pipes.
Therefore, a comparison is needed.
What is a Stainless Steel Welded Pipe?
A stainless steel welded pipe is made by curling a steel strip or plate with a machine and mold.
It is called a “welded pipe” because the edges are welded together.
Advantages:
A simple production process is used.
High production efficiency is achieved.
Many varieties and sizes are available.
Equipment costs are kept low.
Thus, stainless steel welded pipes are now widely used.
They often replace seamless pipes, especially in heat exchange equipment, decoration, and medium- or low-pressure fluid transport.
What is a Galvanized Pipe?
A galvanized pipe is a normal steel pipe.
A layer of zinc is sprayed or dipped onto its surface.
This zinc layer prevents rust.
However, once the zinc is worn off, the pipe can rust quickly.
Application Range Difference
Stainless Steel Welded Pipe
It is mainly used in:
Petroleum and chemical industries
Medicine and food industries
Light industrial transportation
Mechanical parts and structures
Decoration and furniture
Because it has lighter weight with the same strength, it is often used in engineering and machinery.
Galvanized Pipe
It is often used in:
Construction and machinery
Coal mining and chemical plants
Electricity and railway vehicles
Automotive parts
Bridges, containers, and sports equipment
Agricultural and petroleum machinery
Hot-dip and electro-galvanizing methods are both used for these pipes.
Overall Comparison
In general:
Stainless steel pipes can replace galvanized pipes in most fields.
Galvanized pipes are not as strong or durable.
Stainless steel welded pipes last longer.
They resist corrosion much better.
Thus, more people are choosing stainless steel pipes today.
