Revealed: the shocking truth why galvanized pipes defy forged bending

Galvanized pipe is a type of steel pipe that has been coated with a layer of zinc to protect it from corrosion. This coating makes the pipe more durable and resistant to rust, but it also makes it more difficult to bend. Forged bending is a process of bending metal by hammering it into shape. This process is often used to bend steel pipe, but it cannot be used to bend galvanized pipe.

Reasons Why Galvanized Pipe Cannot Be Bent by Forged Bending

There are several reasons why galvanized pipe cannot be bent by forged bending:

• The zinc coating is too hard. The zinc coating on galvanized pipe is much harder than the steel pipe itself. This makes it difficult to hammer the pipe into shape without damaging the coating.
• The zinc coating is brittle. The zinc coating on galvanized pipe is also brittle. This means that it can crack or chip if it is hammered too hard.
• The steel pipe is too thin. Galvanized pipe is typically made from thin steel pipe. This makes it difficult to bend the pipe without collapsing it.

Alternatives to Forged Bending

If you need to bend galvanized pipe, there are several alternative methods that you can use:

• Cold bending: Cold bending is a process of bending metal by applying pressure to it without heating it. This process can be used to bend galvanized pipe, but it requires specialized equipment.
• Roll bending: Roll bending is a process of bending metal by passing it through a series of rollers. This process can be used to bend galvanized pipe, but it can leave a slight bend in the pipe.
• Induction bending: Induction bending is a process of bending metal by heating it with an induction coil and then bending it. This process can be used to bend galvanized pipe, but it can be expensive.

Recommendations

Galvanized pipe cannot be bent by forged bending because the zinc coating is too hard, brittle, and the steel pipe is too thin. If you need to bend galvanized pipe, you can use one of the alternative methods described above.

Top Questions Asked

Q: Can I bend galvanized pipe with a pipe bender?

A: Yes, you can bend galvanized pipe with a pipe bender, but you need to use a pipe bender that is specifically designed for galvanized pipe.

Q: What is the best way to bend galvanized pipe?

A: The best way to bend galvanized pipe is to use a cold bending machine. This machine will apply pressure to the pipe without heating it, which will prevent the zinc coating from cracking or chipping.

Q: Can I bend galvanized pipe by hand?

A: It is possible to bend galvanized pipe by hand, but it is difficult and time-consuming. If you need to bend a lot of galvanized pipe, it is best to use a machine.
