These are systems designed to heat or cool a primary substance. They are utilised to transfer heat between a working fluid and a source, such as a liquid, gas, or a mixture of both. Also, the media might be separated by a solid wall preventing mixing or direct contact between the materials.
Most heat exchanger manufacturers in India specialise in producing heat exchangers for different industrial applications such as chemical processing and power generation. Here’s how heat exchangers are manufactured.
How are Heat Exchangers Made?
The first step in manufacturing heat exchangers is the design, which begins with user data.
Data Specifications
Each heat exchanger made is different. Knowing these differences lies in customers’ data to heavy engineering companies in India. This allows the experts to design a bespoke heat exchanger that fits its purposes.
Operating Conditions
There are different operating conditions that experts must consider in the design phase. They include:
- Internal size
- Mechanical aspects
- International standards
- Noise
- Vibration
- Environmental conditions
- Fluid
- Design software
Heat exchanger manufacturers in India use different state-of-art software to assist with the design.
Manufacturing Stage
Once the design is complete, the experts proceed to the production stage. The specialists who designed the exchanger completed a thorough handover with the manufacturing team. This crew uses the manufacturing sketches to build the exchanger.
The construction of the heat exchangers could comprise different production processes and methods such as:
- Tube expansion
- Water jet cutting
- Metal forming
- Metal drilling
- Laser cutting
- Different types of welding
- Painting
Checking for Errors
Even though engineers must perform a complete handover with the product production team, heat exchangers have several individual components. This means there’s a chance of errors during the transaction.
Furthermore, if the CAD models fail to compute how the final components fully fit together, the person making the unit can’t get some important parts.
If a component has an error, remaking it can be pricey and rarely feasible. So, the engineers proceed to work on finding a solution that fits the unit’s specifications without jeopardising heat transfer efficiency.
Therefore, the engineering and production teams must work jointly to develop solutions while making the heat exchangers.
New engineering graduates at heat exchanger manufacturers in India start with a duration in the shop to know how the units are manufactured and gain experience. It assists in building a real-life understanding of how designs come together. For instance, you can’t reach a bolt that requires fastening, which may not be seen on the CAD. The process ensures the engineers understand the production element of creating heat exchangers to make the procedure from design to production smooth.
Inspections
Once the heat exchanger manufacturers in India have produced the units, they undergo inspection and testing to offer their customers reliable and safe exchangers. Once products pass, the heavy engineering companies in India ship them to customers with a user manual and certifications.
Making heat exchangers is complex, involving several stages and skilled professionals before arriving at the end product. Besides, the process is unique to each bespoke heat exchanger made. India’s most reliable heavy engineering companies strive to build long-lasting relations with their customers. This means they can offer the highest service and quality of heat exchangers.
