Large diameter silicone hose (white) because of its flexibility, high temperature resistance, corrosion resistance and health performance, widely used in medical, food, chemical, industrial and other fields. The following is a detailed description of its connection process and use:
First, the connection process
Flange connection
Process steps:
Install flanges at both ends of the hose (the material should be compatible with the silicone tube, such as PP, stainless steel).
Use bolts to align the flange with the equipment or pipe flange, with a sealing gasket (silicone or PTFE) in the middle.
Features:
Suitable for high pressure or large diameter pipeline system, good sealing, easy to disassemble and maintain.
Pay attention to the concentricity of the flange and the pipe to avoid stress concentration resulting in leakage.
Clamp (throat clamp) connection
Process steps:
Insert the hose into the joint (e.g. stainless steel, plastic joint), making sure the insertion depth is sufficient.
Use stainless steel clamp or double steel wire to strengthen the clamp and tighten it, and apply even force to avoid deformation.
Features:
Fast installation, low cost, suitable for low or medium voltage scenarios.
Check the tightness of the clamp regularly to prevent it from falling off due to vibration.
Hot vulcanized bonding
Process steps:
Polish the end of the silicone tube and clean the surface.
Coated with silicone special adhesive (such as RTV silicone glue), heat pressure vulcanization bonding.
Features:
High connection strength, good sealing, suitable for permanent connection.
Requires professional equipment and technology, complex operation.
Quick fitting (sanitary connection)
Process steps:
Choose quick-fitting fittings that meet hygienic standards (such as Tri-Clamp construction).
Attach hose to joint and lock with snap or thread.
Features:
Suitable for food, pharmaceutical industry, easy to clean, no dead corners.
Joint material should be 316L stainless steel or food grade plastic.
2. Usage
Application field
Medical industry: For ventilators and extracorporeal circulation equipment, white silicone tubes are easy to observe the internal fluid state and must meet biocompatibility standards (such as USP Class VI).
Food industry: conveying liquid or gas, high temperature resistance (-60℃~250℃), in line with FDA standards, white surface is easy to check cleanliness.
Industrial field: chemical medium transportation, ventilation and dust removal, acid and alkali corrosion resistance, flexibility to adapt to complex pipeline layout.
Precautions for use
Installation environment: Avoid contact with sharp objects to prevent scratches; The bending radius should not be too small to prevent folding.
Media compatibility: Confirm the compatibility of silicone material and conveying media (such as oil, strong oxidizer).
Temperature and pressure: The long-term use temperature is recommended not to exceed 200 ° C to avoid overpressure resulting in tube explosion.
Cleaning and maintenance: The white silicone tube is easy to show dirty, and it should be washed regularly with neutral detergent to avoid the use of strong acids and alkalis.
Q&A
Leakage: due to the connection is not tight or aging of the gasket, the gasket needs to be replaced regularly.
Aging discoloration: Long-term exposure to ultraviolet light or high temperature environment may lead to yellow white silicone tube, anti-aging model should be selected.
Iii. Summary
The key to the white large diameter silicone hose is to select the appropriate connection process according to the application scenario (such as priority quick-fitting joints in the medical field, multi-purpose flanges or clamps in the industrial field), and strictly follow the cleaning and maintenance specifications. Its advantages are safe, durable and easy to observe the internal state, but it is necessary to pay attention to the suitability of materials and processes to extend the service life.
