Learn More about the Process of Induction Bending

Piping is an essential element in the construction industry and has universal applications, especially in petrochemical and energy projects. Since piping is such a crucial aspect, numerous techniques have evolved how pipes are fabricated, bent, and fitted. One such technique is induction bending.

What is High Frequency Induction Bending (HFIB)?

Induction bending employs the principle of induction to heat a pipe locally. As a result, the pipe has a narrow heat band. As the pipe is pushed by an accurate drive system in a heavy frame, the heated content is moulded into a curve in a narrow zone.

After that, the bent part is allowed to cool by water/air to form the bent shape. This process of bending is both automated and continuous.

Major Advantages of Induction Bending

Like other advanced techniques in piping, induction bending has certain advantages that are important to be mindful of some worthwhile advantages of this technique are:

  • A decrease in the number of weld joints required
  • Reduced delivery time and cost
  • Decreased fabrication costs and time
  • System Integrity
  • Flow Characteristics
  • Power requirement considerations
  • Opportunity to obtain any angle of bend and any radius directly

In the case of this bending process, the subsequent fabrication process will be instant. In essence, there will be no need for you to remain dependent on elbows. Overall, the method is favourable and popularised for good reason.

Essential Applications of Induction Bending

Most of the induction bends are in pipeline systems used to transfer liquids and gases. They are also used in applications that require bends with larger diameters with accuracy and dependability as well as laminar smooth flow. Induction bends are commonly used in the following industries:

  • Power plants
  • Ship building
  • Metallurgical industries

The Process of Induction Bending

Induction bending consists of several steps that are needed to be done with precision and care. The steps involved in this method are:

  • The inspected pipe which is to be bent is fastened hydraulically in the machine bed
  • Induction heating and cooling coils are installed all around the pipe. The induction coil can be modified in three planes to ensure uniform heating.
  • The bend radius required can be corrected by making adjustments to the front clamp and radius arm. There is only one pointer to show the accurate extent of turning. Arc lengths are further marked on the pipe.
  • Once everything is in place, the water level, hydraulic pressure, and switches are checked before the induction bending operation begins.
  • Once the required temperature range is reached, the pipe is pushed forward at a steady pace.
  • The resultant heated pipe is then sprayed with water just on the outside of the pipe.
  • The induction bend is sent for an inspection.

Final Words

Induction bending is an advantageous technique involved in piping systems to make the project more economical and secure. Since induction bending has several applications in important projects related to petrochemical and energy, people must know about the value of this technique and how to implement it correctly.
