Product Description

 Stainless Steel NBR Limit Rods Flexible Metal Bellow Expansion Joint Dismantling Joint Double Flange Compensator

A stainless steel industrial corrugated hose flange fitting is a flexible connector made of corrugated stainless steel with welded flange ends. It is used in systems that handle steam, gas, or chemicals, especially where vibration, thermal expansion, or misalignment occurs. Common in chemical plants, power stations, and HVAC systems, it ensures leak-free, durable, and safe fluid or gas transmission under dynamic conditions.

Working Principle
The stainless steel industrial corrugated hose flange fitting works by using a corrugated metal hose to flex and absorb movement while maintaining a sealed flow path. The flange ends are welded to allow secure, bolted connections to piping systems. As fluid or gas flows, the corrugations flex to handle vibration, thermal expansion, or misalignment, ensuring leak-free operation under dynamic industrial conditions.

Size Range: DN15-DN300 (1/2"-12")
Pressure Rating: up to 25 bar
Temperature Range: -196°C to +450°C
Material: 304 / 316L stainless steel
Flange Standard: ANSI / DIN / JIS
Length: Customized on request
Braid Layer: Single or double stainless steel wire braid (optional)

Quality guarantee of 3 years

Product Description

Stainless steel sanitary accessories are widely used in high-cleanliness industries and have the following significant feature:

1.Corrugated Hose Core
The body uses a corrugated stainless steel hose to provide flexibility, allowing it to absorb vibration and axial movement without deformation.

2.Precision Welded Flange Ends
Flange connections are TIG welded to both hose ends, creating a leak-proof and pressure-resistant joint ideal for industrial systems.

3.Reinforced Multi-Layer Structure
Some models incorporate braided or layered reinforcement to increase burst resistance and extend service life in high-pressure environments.

4.Standard Flange Compatibility
Flanges conform to ANSI, DIN, or JIS standards, ensuring universal fitment with pumps, valves, or fixed pipeline systems.

5.Corrosion-Resistant Construction
The entire assembly is made from 304 or 316L stainless steel, offering excellent resistance to chemicals, steam, and environmental wear.

6.Compact Design for Tight Spaces
Short-length construction makes it suitable for space-constrained installations, reducing stress on system components and improving layout efficiency.
