304/316 Stainless Steel Quick-Loading Hose/Hygienic Chuck Metal Bellows
Stainless steel sanitary bellows is a flexible connection pipe used in high-sanitation industries such as food, pharmaceuticals, and bioengineering. It has good flexibility, corrosion resistance, and hygienic properties. It is usually made of stainless steel (such as 304 or 316L), and the inner and outer surfaces are mirror-polished to meet health standards such as GMP and FDA.
Working principle
The working principle of stainless steel sanitary bellows is based on its corrugated elastic structure. Through the elastic deformation ability of the bellows body, it realizes flexible connection, displacement absorption, deformation compensation and other functions during system operation, while ensuring the hygiene and sealing of the medium transportation process.
Parameters
Nominal diameter: usually DN15 to DN100
Length: customizable, usually 300mm to 3000mm
Working pressure: usually ≤1.6MPa
Working temperature: usually -40ºC to 150ºC
Bending radius: minimum bending radius is about 3 times the outer diameter
Material: commonly used 304 or 316L
Polishing degree: Ra≤0.8μm, mirror-grade sanitary polishing
Connection method: quick-install, welding, thread, etc. optional
Quality guarantee of 3 years
ISO 9001, FDA, SGS approved materials
7-10 days fast delivery on urgent requirements
20 years' Rich exporting experience to make you easy and happy with custom work
Stainless steel sanitary valves are widely used in high-cleanliness industries and have the following significant advantages:
