Certification by third-party inspection agencies is available, providing customers with documented assurance of the products reliability, performance, and adherence to industry safety standards.

Customizable Dimensions and Material Options

Manufactured to precise design calculations, these expansion bellows offer flexibility in dimensions, thickness, and surface finishes, accommodating diameters from 50 mm to 1000 mm and thickness ranging from 0.5 mm to 2.5 mm. High-grade stainless steel and nickel alloys provide options for elevated flame resistance, chemical tolerance, and pressure handling, suitable for demanding industrial specifications.

FAQs of Expansion Bellows:

Q: How are expansion bellows installed in industrial piping systems?

A: Expansion bellows are installed using flanged, welded, or threaded end connections, depending on pipe specifications and design requirements. Installation lengths are determined by calculation to ensure optimum movement compensation.

Q: What processes are used to manufacture these expansion bellows?

A: The bellows are fabricated using hydraulically or mechanically forming methods. This ensures structural integrity and precise dimensional control, meeting the specified tolerances and thickness requirements.

Q: When is a hydro test or third-party inspection available for the product?

A: Hydro test, material test, and third-party inspection services are conducted during manufacturing or prior to dispatch, complying with client and regulatory standards for safety and reliability.

Q: Where can these expansion bellows be used?

A: They are suitable for application in industrial piping, HVAC, ventilation, exhaust systems, chemical processing plants, and power stations, wherever flexible compensation for pipe movement is needed.

Q: What benefits do helium leak tested bellows offer?

A: Helium leak tested bellows guarantee leak rates below 1x10 mbarl/s, assuring high containment integrity for critical fluid or gas transport, which is essential for safety in sensitive industrial processes.

Q: How is the appropriate size and compression ratio determined?

A: Size, length, and compression ratio (up to 20% of free length) are calculated based on system movement, pressure conditions, and application requirements to ensure effective compensation without overloading the bellows.

Q: What are the advantages of using stainless steel or nickel alloy materials for these bellows?

A: Stainless steel (SS304, SS316) and nickel alloys provide exceptional resistance to corrosion, chemicals, flames, and temperature extremes, ensuring long service life and reliable performance in demanding environments.
