Induction Pipe Bending

Induction Pipe Bending   

The other kind if forming accepted in Spad Sanst professional is pipe bending in heating way (size: 3″~36).

In this production process manufacture has to observe different international standards. These standards include the material confirmation, production process, destructive and non- destructive test during the production to the test and final supervision. By observing all international standards this company could deliver it’s products to a lot of offshore and onshore national projects with the highest quality level and as fast as possible.

 

Bending in hot way is a completely developed one to give the services with the most accuracy and efficiency good for expanded spectrum of application. It can cover some limitations of cold bending technique like.

Disability to curve in less radius, such as distortion and wall thinning.

 

The pipe is put on a machinery with a movable arm with defined parameters related to the bending, The material is then through hydraulically system and between the rollers related to the section. By exploiting the thermal energy through an induction coil and correct numerical control, this process would be inspected. Heat and Quenching Related to the piece, thickness and alloy of the section un a part are don, they’re heated after passing the section, then the Quench will be cold by water air or mixture of both.

 

 

 

 

Mixture of speed heat and coldness can provide the pipe heading with higher radius without the section deformation.

 

Typical application sectors:

Power generation – Construction – Offshore oil and gas – Petrochemicals – General fabrication

 

Induction Bending Information

Capability and Capacity

Induction bending services in Spad Sanat are given comprehensively and unique.

Advantages of using induction bending:

Induction pipe bending of the pipes range from 3 inch to 36 inches with the material up to 50 mm thickness.

The possibility to bend the pipe with lower radius and cold bending technics.

The use of uncovered pipe.

Decreasing the welding need with mixing bending.

More efficient and faster in other methods.

Tubes and pipes, either seamless or welde

How does induction bending work?

Bending in hot way is a completely developed one to give the services with the most accuracy and efficiency good for expanded spectrum of application. It can cover some limitations of cold bending technics like.

Disability to curve in less radius, such as distortion and wall thinning.

THE PROCESS

The pipe is put on a machinery with a movable arm with defined parameters related to the bending, the material is then through hydraulically system and between the rollers related to the section. By exploiting the thermal energy through an induction coil and correct numerical control, this process would be inspected. Heat and Quenching Related to the piece, thickness and alloy of the section un a part are don, they’re heated after passing the section, then the Quench will be cold by water air or mixture of both.

Mixture of speed heat and coldness can provide the pipe heading with higher radius without the section deformation

In machinery planning, there aren’t any limitation about the pipe length in hot bend, there no shrinkages and forming is done without a former or mandrels and by preparing a strong support through the cold pipe in Tow sides of hot part.

 

Advantages of using induction bending

Possibility to produce any limitation in the bending radius.

Superior quality in ovaliity, decreasing the wall thickness and ending the surface.

Avoiding the need of the section just with one joint, easy to us and available, affordable and more direct

Producing the joint with the some wall thickness.

Big bending radius decreases the ability of pieces.

Without cut, rounding, piercing (punching), fitting or thermal/welding operations.

Pipe bending with the radius lower than the cold bending technics.

The possibility to make some solitary bending in a pipe.

Decreasing the need to weld with mixing bending, improving the pipe versatility at the end of the work.

Avoiding the boil in critical points.

Less need to none-destruction test, control more than costs.

Faster and more efficient than previous methods.

Process eliminates the need for sand filling, mandrels or formers.

Changing the bending specification can be done right until the last minute of the production.
