Product Description
Features:- Optimum functionality
- Minimum maintenance
- Longer serving life
Functionality:
- Single or double line bellows assembly is connected with the balancing bellows with the help of tie rods or bars. This helps in restraining the axial and compressive thrust that is caused due to internal pressure
- It also allows free lateral movement
Customized Design FlexibilityThese bellows are engineered to align with customer specifications, covering single or multi-ply construction, varied lengths, and a broad diameter range from DN 25 mm to DN 2000 mm. End fittings such as loose flange, fixed flange, and weld ends offer installation adaptability for different equipment and piping requirements.
Superior Materials and Corrosion ResistanceFabricated using premium materials including Stainless Steel, Inconel, Hastelloy, Brass, and Copper, our bellows are highly resistant to corrosion, even in highly aggressive fluid environments. This ensures prolonged lifecycle and reliability in demanding chemical and thermal processes.
High Performance under Extreme ConditionsDesigned to withstand maximum temperatures up to 800C and working pressures up to 40 bar, these axial bellows ensure dependable performance in challenging operating scenarios, backed by rigorous leak testing (hydro or pneumatic) for safety and operational integrity.
FAQ's of Heat Exchanger Bellows:
Q: How are the Heat Exchanger Bellows tested for leaks and suitability in aggressive environments?
A: Each bellows is subjected to 100% hydro or pneumatic leak testing to confirm integrity and reliable performance under operational pressures. The use of highly corrosion-resistant materials such as Stainless Steel, Inconel, and Hastelloy ensures compatibility with aggressive fluids commonly found in heat exchanger and process equipment applications.
Q: What customization options are available for these bellows in terms of size and end connections?
A: The bellows can be custom-built according to client specifications for length, ply number (single or multi-ply), diameter (DN 25 mm to DN 2000 mm), and end fittings. Customers can choose from loose flange, fixed flange, welded ends, and select flange designs (DIN, ANSI, JIS, or custom) to match their process requirements.
Q: When should axial expansion bellows be used in process equipment and heat exchangers?
A: Axial expansion bellows are ideal for compensating thermal expansion, reducing mechanical stresses, and containing vibrations in shell and tube heat exchangers and various industrial process equipment where high temperature and pressure variations occur.
Q: Where can these bellows be installed, and which industries do they serve?
A: These bellows can be installed in shell and tube heat exchangers, piping systems, and process equipment across sectors such as chemical processing, petrochemicals, oil and gas, power generation, and HVAC plants, among others throughout India.
Q: What manufacturing techniques are utilized to form these heat exchanger bellows?
A: The bellows are shaped using advanced techniques like hydraulic forming, expansion forming, and roll forming, depending on the design and material selected. This ensures precise geometry and optimal performance for axial movement and pressure containment.
Q: How do these bellows benefit operators in harsh fluid and temperature environments?
A: Operators benefit from reduced risk of failure and downtime due to the bellows' high corrosion resistance, ability to handle aggressive media, and dependable performance at temperatures up to 800C and pressures up to 40 bar, making them a reliable solution for demanding process conditions.
