High-Sensitivity Helium Leak Testing Equipment for Metal Corrugated Bellows and Corrugated Hose Sealing Inspection

Product Description

HeJin's Metal Corrugated Bellows Helium Leak Testing Equipment is designed for manufacturers who need to identify tiny leakage paths in metal corrugated hoses, bellows and other sealed components where conventional pressure or bubble testing may not provide sufficient sensitivity.

Using helium as a tracer gas and a helium leak detection system to monitor leakage, the equipment provides a practical method for evaluating sealing integrity at critical welding, joint and connection areas.

Product Introduction

A metal corrugated bellows assembly can look perfect on the outside and still contain a microscopic leakage path.

For applications where the integrity of a weld, formed bellows section, end connection or sealed cavity matters, a simple pressure-hold test may not always reveal the smallest defects. This is where helium leak testing becomes valuable.

HeJin's metal corrugated bellows helium leak testing solution is developed around the principles of tracer-gas leak detection. Helium is introduced into or applied around the test component according to the selected test method, while the helium leak detection system identifies leakage and provides a quantitative evaluation of sealing performance.

The system is intended to help manufacturers move from "the component appears sealed" to "the sealing performance has been measured."

For production engineers, this means greater confidence in outgoing quality. For quality teams, it provides a more objective inspection method. For manufacturers supplying demanding customers, it creates a clearer basis for documenting leak-tightness requirements.

Application Industries

• Automotive Components

  Metal bellows, flexible pipe assemblies and sealed metallic components used in automotive systems can require controlled leak-tightness inspection.

• Refrigeration and HVAC

  Corrugated metal tubing, flexible connections and sealed refrigeration-related components may require fine leakage inspection.

• Vacuum Equipment

  Vacuum components and bellows assemblies can benefit from high-sensitivity helium leak testing when maintaining vacuum integrity is critical.

• Industrial Gas Systems

  Flexible metal hoses and sealed gas-handling components can be evaluated for leakage before shipment or during quality verification.

• Semiconductor and Precision Equipment

  Where clean, reliable and leak-tight gas pathways are important, helium leak testing can be used as part of quality-control procedures.

• Energy and Industrial Equipment

  Metal bellows, expansion components and welded piping assemblies can be inspected for sealing integrity during manufacturing and validation.
