To select an annular wave metal hose, first define the conveyed medium, operating pressure and temperature, movement, connection type, and installation environment. Then match the hose material, nominal size, corrugation design, reinforcement, and end fittings to those conditions. No single hose specification suits every application, so treat published ratings as product-specific and confirm the complete assembly’s limits with the supplier before ordering.
This guide is for engineers, maintenance teams, and industrial buyers preparing to evaluate or request a quote for a metal hose assembly. At Hengshui Xinchi Hose Manufacturing Co., Ltd., we recommend sharing the operating conditions and installation details early, so a supplier can assess the hose and its fittings as one assembly rather than considering the flexible tube alone.
Use this guide when a rigid pipe connection cannot accommodate the movement, vibration, or routing required in your equipment or process line. It can also help buyers comparing metal hose options for gas, liquid, thermal, or equipment connections. It is not a substitute for engineering review where failure could create a safety or environmental hazard.
An annular wave metal hose is a flexible metal tube formed with ring-shaped corrugations around its circumference. The corrugations allow the tube to bend and accommodate certain movement, while the metal construction can be appropriate for service conditions where a non-metallic hose is not suitable. The assembly may also include braid, end fittings, and other specified components.
The corrugated inner hose provides the flow path and flexibility. An external wire braid, when included, helps restrain pressure-related expansion and can contribute to the assembly’s mechanical support; its presence does not by itself establish a pressure rating. End fittings connect the hose to the system, so fitting material, connection style, attachment method, and assembly design must all be considered together.
Stainless steel grades such as 304 and 316L are commonly considered for metal hose applications, but selection depends on the medium, temperature, concentration, and external environment. Compatibility should be checked against the actual fluid or gas and operating conditions; a grade name alone does not prove suitability. Fittings and braid should also be reviewed for compatibility with the hose and the service environment.
When requesting a quote, identify the nominal diameter, overall length, working pressure, temperature range, medium, connection type, and expected movement. Also state whether the hose will be exposed to vibration, outdoor conditions, corrosive substances, or repeated flexing. These details help the supplier assess the configuration and clarify any limits or information still needed.
| Selection item | What to provide or verify | Why it matters |
|---|---|---|
| Operating conditions | Medium, pressure, temperature, and operating cycles | These affect material compatibility and assembly suitability. |
| Hose configuration | Nominal size, length, corrugation, and braid requirements | The configuration should match the flow path and installation. |
| Connections | Fitting type, material, orientation, and connection standard | Correct ends are needed for fit and assembly integration. |
| Movement and routing | Direction, amount, frequency, and minimum space available | Incorrect routing or movement can shorten service life. |
Annular corrugated metal hose is considered in industrial settings such as equipment connections, process lines, and systems that need a flexible metal connection. The right choice depends on how the hose will be installed and used, not simply on the industry name. A hose used for occasional alignment movement may face different demands from one exposed to continuous vibration or repeated movement.
Describe whether the hose will experience static offset, occasional movement, vibration, or repeated flexing. Identify the movement direction and show the available routing space, because bending the hose more tightly than the design permits can place extra stress on the corrugations and fittings. Follow the supplier’s guidance for bend radius, installation, and any movement limits for the proposed assembly.

For initial inquiry purposes, an example project brief might specify a 25 mm nominal bore, 10 bar working pressure, and 150°C operating temperature. These figures are illustrative inputs, not a recommended specification or a rating for any particular product. A supplier must review the actual conditions and the complete assembly before confirming suitability.
A frequent mistake is choosing by nominal diameter and pressure alone while leaving out temperature, medium, or movement. Another is assuming that a hose’s material or braid makes it suitable for all corrosive or high-pressure service. Buyers should also avoid treating a flexible hose as a substitute for correct pipe support, alignment, or movement control.
Do not estimate length without accounting for connection geometry and installation routing. Avoid twisting the hose during installation, and do not use it to compensate for misaligned piping unless the assembly is designed for that movement. Where operating conditions may exceed those initially specified, discuss the variation before finalizing the order.
Price depends on the specified hose size and length, material, braid, fitting type, assembly complexity, and order quantity. Minimum order quantities and production lead times can vary with the requested configuration and current production schedule, so they should be confirmed in the quotation rather than assumed. For an accurate estimate, provide the application details, quantity, delivery destination, and requested schedule.
When comparing quotations, check that suppliers are pricing the same assembly scope. Confirm whether the quote includes fittings, braid, documentation, packaging, and any requested inspection or testing requirements. If a supplier proposes a substitute material or connection, ask for the change to be identified and approved before production.
At Hengshui Xinchi Hose Manufacturing Co., Ltd., we support B2B inquiries for flexible metal hose requirements by reviewing the application information and requested configuration. We encourage buyers to send a specification sheet, drawing, or clear connection details so we can assess what information is available and identify questions that need resolution. Product availability, customization, order quantity, documentation, and lead time should be confirmed for each inquiry.
An annular wave metal hose should be selected as a complete assembly for defined operating and installation conditions. Start with the medium, pressure, temperature, movement, size, and connections, then verify materials and configuration with the supplier. Do not treat illustrative values, generic material descriptions, or the presence of braid as proof that a particular assembly is suitable.
To prepare for evaluation or quotation, gather your operating data, required quantity, connection details, and installation drawing or measurements. Send these details to Hengshui Xinchi Hose Manufacturing Co., Ltd. for a product discussion and request confirmation of the proposed assembly’s configuration, limits, and commercial terms before placing an order.
