How to bend a 3 inch Galvanized pipe?

How to bend a 3 inch Galvanized pipe?

(OP)


   Dear all

    First i want to express you all my best wishes and seasons greeting. Now please advice me how could i form(bend) a 3" Galva. pipe around a 50 meter dia. half circle , 3" pipeline is for air delivery which has to be passwed through a 2 meter wide channel around a 50 meter half circle.
 My second question is how can i discharge seawater from a tank with depth of 5 meter all the water should be discharged? No submersible tank is to be used ?

Hi Keyhanafshar:

Thanks for your greetings and wills, Have the same from me.

I will do a dwg in acad  to try to understood your task to do.

Does you handle any cad system?
Which one, can you open DXF files from ACAD R14 or  acad-r14.dwg files?
As I understood, you have a semicircular chanel whose internal dia is 50 meter and the outside diameter is 54 mm
True?

About the salt water tank:

My second question is how can i discharge seawater from a tank with depth of 5 meter all the water should be discharged?

Why the question symbol.

No submersible tank is to be used ?
Does you mean " NO SUBMERSIBLE PUMP"

Which is the volume tank, ist is open, material, location ?

RE: How to bend a 3 inch Galvanized pipe?

Not really sure what the second half of your question is about.  The first isn't too hard though.

Segmental bending is probably the way to go.  That is, every meter put in a little less than one degree of bend using a pipe bending machine.  It doesn't sound like you need a uniform bend, just that your 3" galvanized pipe fits into the 2 meter wide channel.  As long as you can lay out segments of pipe, bend the sections, weld them up and then lower the assembly into the trench you should be fine.  If you have to insert the assembly from one end you will have some additional challenges but as long as the bending is the same it should work okay.

Oh, bending galvanized pipe can destroy the coating but you don't need to bend much so it should be fine.  That is, assuming you really want to use galvanized pipe.

Hi visitor, weldimg will destroy the coating  too
