Manufacturing Process of Our Corrugated Stainless Steel Hoses
At QualityFlex, we focus on minimizing residual stress during the manufacturing of corrugated metal hose. Using innovative designs and custom-built equipment, we’ve perfected the art of forming corrugations with our Stress-Lite™ annular corrugating processes.
- Hydroforming Process: Expands a section of the tube with high-pressure water, ensuring no torsion, while the tube is fed axially from both directions. This process creates consistent, durable corrugations without adding unnecessary stress to the material.
- Crimp Forming Process: Compresses the tube using a “shutter-crimp” technique, again without torsion, while being fed axially from both directions. This results in precise and strong corrugations, enhancing the hose’s performance and longevity.
With these processes, QualityFlex ensures that our stainless steel corrugated hose offers superior flexibility, durability, and reliability in every application.
Our advanced processes create annular hoses with minimal work hardening, uniform wall thickness, and no residual torsional stress. This results in our hoses offering superior flexibility, longer cycle life, and unmatched durability. At QualityFlex, we deliver top-tier corrugated metal hoses for demanding applications.

Offering Various Types of Corrugated Stainless Steel Hoses
Corrugated Flexible Metal Hoses :
Our corrugated flexible metal hose, crafted from premium stainless steel, offers exceptional flexibility and durability. Designed to handle high pressure and full vacuum, these hoses are reinforced with high-tensile braiding, ensuring reliable performance in demanding industrial applications.
Corrugated Stainless Steel Flexible Hoses:
Corrugated stainless steel flexible hoses are engineered for maximum durability and flexibility, handling full vacuum and high pressure with ease. Made from premium AISI 321 and 316L stainless steel with reinforced AISI 304 braiding, they deliver reliable performance in demanding applications.
Annular Stainless Corrugated Hoses
The process of making annular metal hoses starts with a high-quality stainless steel strip. This strip is rolled into a thin-walled tube with a strong, clean seam weld that doesn’t oxidize. Once welded, the tube is corrugated to make it flexible.
- Type 321 Stainless Steel: The industry standard, a chromium-nickel steel stabilized to resist corrosion between grains. It works well in temperatures from 1500°F down to cryogenic levels of -320°F.
- Type 316 Stainless Steel: This steel, with added molybdenum, offers better corrosion resistance. It is suitable for use in temperatures from 900°F to cryogenic levels of -320°F.
Corrugated Stainless Steel Hose with Stainless Steel Overbraid
Our corrugated stainless steel hoses are reinforced with stainless steel wire braids to enhance pressure-handling capabilities. These hoses come with either a single braid (one layer) or a double braid (two layers) for higher working pressures. Larger hoses have extra braided layers for added durability.
Designing the right braid for each hose type requires careful engineering to balance strength and flexibility. Our braided hoses offer key advantages:
- High Braid Coverage: Our hoses have a high braid coverage, providing longer life and better protection against damage.
- Precision Machine Braiding: The braid is tightly woven directly onto the hose, preventing deformation and ensuring consistent, long-lasting performance.
Pressure Loss in Corrugated Stainless Steel Hoses
Corrugated stainless steel hoses, including SS corrugated hose and stainless corrugated hose varieties, exhibit significantly higher pressure loss compared to new welded steel pipes. Specifically, the pressure loss in these hoses can be up to 100% higher. To compensate, a 15% increase in hose diameter is often necessary to match the pressure loss characteristics of standard steel pipes.
This higher pressure drop is attributed to the corrugated nature of the hose’s bore. To accurately determine the pressure drop for different flow rates, refer to the provided chart. Locate the required flow rate on the baseline, then trace a vertical line from this point until it intersects the nominal bore line. The pressure drop corresponding to this intersection is displayed on the vertical axis of the chart. Understanding these dynamics is crucial for ensuring optimal performance and efficiency in your system.
Temperature Correction Factor for SS Corrugated Hoses
When stainless steel corrugated hoses are used in high-temperature environments, it’s essential to adjust their pressure ratings accordingly. To ensure safe and reliable performance, the working pressure provided in the specifications should be multiplied by a temperature correction factor. This adjustment accounts for the decreased strength of the stainless corrugated hose at elevated temperatures. Always refer to the correction factor table to accurately determine the hose’s pressure rating under high-temperature conditions.
Advantages of Corrugated Steel Hoses
- Wide Temp Range: Performs in extreme temps from (-200°C to +650°C), safe for high-temp use.
- Corrosion Resistance: Stainless steel resists corrosion, abrasion, mold, and fire.
- Temperature Resilience: Handles sudden temp changes without losing integrity.
- Flexible Installation: Ideal for challenging locations, compensates for thermal expansion.
- Noise Reduction: Minimizes noise in piping systems under high pressure.
- Long Lifespan: Resistant to damage, offering a cost-effective, durable solution.
- High Strength: Excellent mechanical resistance with reasonable weight for durability.
FAQS
Stainless steel corrugated hoses are used for high-pressure gases and liquids, handling temperature changes, and protecting against vibration in industrial, automotive, and aerospace applications.
The flow capacity of a corrugated hose depends on its diameter, length, and fluid properties. Typically, these hoses provide good flow rates, but exact capacities vary based on hose specifications and the application.
Corrugated SS hoses include standard flexible types, close-pitch options for specialized uses, and single or double-braided versions for added pressure handling and flexibility.
