Soshh Ultra Flex Pure PTFE Bellows for Precision Load Cell Connections
![Ultra-flexible pure PTFE corrugated bellows with rotatable flanges for precision load cell weighing systems]()
Product Overview
Soshh Ultra Flex series represents the premium standard in pure PTFE convoluted bellows, specifically engineered for applications where mechanical piping stress interferes with sensitive instrumentation. By utilizing a 100 percent pure solid molded PTFE core without heavy metal braiding, this connector provides the ultimate flexibility required for modern industrial weighing systems and chemical processing lines.
Overcoming the Weighing Accuracy Bottleneck
In modern processing plants, rigid piping connections are the leading cause of calibration drift and measurement errors in load cells and weighing hoppers. Standard braided metal hoses or thick walled plastic tubes possess inherent mechanical stiffness. When temperature shifts or pressure fluctuates, they transfer parasitic forces to the weight sensors. Soshh Ultra Flex bellows isolates the vibration and movement entirely, maintaining a zero stress buffering zone so that your instruments report 100 percent accurate data.
Key Engineering Features
- Pure PTFE Construction: Formulated from high density virgin PTFE, offering universal chemical compatibility and an operating temperature range suitable for aggressive processing environments.
- Zero Stiffness Bellows Design: The specialized convolution profile maximizes axial and lateral flexibility, bringing structural resistance down to near zero.
- Rotatable Flange System: Equipped with ASME B16.5 Class 150 lap joint rotatable flanges. This allows the field engineers to rotate the flange freely during installation, completely preventing hazardous mechanical torque and alignment stress.
Large Diameter Customization Capabilities
While standard industry offerings are limited to small diameters, Soshh specializes in heavy duty engineering designs. We support large diameter requirements up to 8 inch (DN200) and even 12 inch (DN300) nominal sizes. These large scale pure PTFE convoluted bellows are thick-walled and CNC-machined to withstand vacuum and low-pressure powder handling environments while maintaining supreme flexibility. Whether you need a large flexible connection for a major weigh hopper or a primary process pipeline, we can customize the length and flange specifications to fit your exact drawings.
Primary Applications
- Precision Load Cell and Weighing Hopper Connections
- Large Diameter Powder and Bulk Solids Handling Systems
- Low Pressure Nitrogen Lines and Gas Supply Systems
- Chemical Dosing and Micro Metering Pumps
- Vibratory Equipment and Screeners Isolation
