Hanovix Bellows

Hanovix is a privately owned industrial group headquartered in Hong Kong, serving as the parent company of: Qinhuangdao Hengchang Flexible Hoses, established in 2000 in Hebei Province (Tier 3 city, the starting point of the Great Wall, highly focused on industrial development in China), specializing in the production of metal hoses, expansion joints, and metal bellows. Hengchang Bellows Limited (Chengdu), established in 2025 in Sichuan Province (Tier 1 city, southern China, hometown of pandas and hotpot), a new, highly automated facility focusing on hydroformed, electroformed, and edge-welded bellows in small diameters for advanced industries such as energy, semiconductor, and scientific research. The Hanovix team has more than 25 years of experience in precision bellows manufacturing and automation. We have been the machinery providers and technical backbone behind many leading bellows and expansion joint manufacturing companies in China.

To provide an accurate quotation, we typically need your drawing or key parameters, including: Type of bellows or assembly Dimensions (ID, OD, length, and convolution count if known) Material preference (e.g., 316L, 321, Inconel, etc.) Working pressure, temperature, and medium Quantity and testing requirements If you’re unsure, our engineers can assist by reviewing your application and recommending the best configuration.

We manufacture using certified materials such as: Stainless Steels: 304, 316L, 321, 347H Nickel Alloys: Inconel 625, Inconel 718, Hastelloy C276 Copper & Brass: For low-pressure or vacuum applications All materials are traceable and accompanied by mill certificates upon request.

All Hanovix products undergo strict testing per EJMA, ASME, and EN ISO standards. Typical tests include: Pressure and leak testing Fatigue life and cycle testing Dimensional and visual inspection Helium leak test (for vacuum or critical applications) We provide complete inspection documentation and certificates with every shipment.

Our minimum order varies by product type and size. For standard bellows that fit our existing tooling, we can support low-volume or pilot batches. For new tooling or custom geometries, minimum quantities are typically defined to optimize cost efficiency and material utilization. Prototype or R&D projects are also welcome under flexible terms.

Custom tooling developed for client-specific products is owned and maintained by Hanovix, but it remains dedicated exclusively to that client’s design. We store and service all tooling in-house for future orders, ensuring consistent dimensional accuracy and long-term repeatability.

Yes — Hanovix serves clients worldwide through a fully managed export process. We provide: Export packaging and moisture protection Custom documentation and certificates of origin Air, sea, or express shipment coordination Our facilities are located for efficient global logistics, ensuring timely delivery across regions.

The vision of Hanovix is to accelerate the world’s transition to advanced automation and sustainable energy. No. Hanovix is a privately owned enterprise focused exclusively on civil and commercial manufacturing applications. We do not participate in defense or government-sensitive projects. Our goal is to build multi-regional manufacturing and service networks that support diverse clients across global industries. When long-term collaboration or regional support is required, Hanovix is capable of establishing local entities or offices to ensure seamless cooperation, communication, and supply capabilities — including in key markets such as the United States and Europe.
