BS 5315 is a British Standard that specifies the requirements for two specific types of hose clamps designed for general industrial use:
Worm-drive hose clamps
Spring-band clamps
This standard establishes critical dimensions, material specifications, performance criteria, and test methods to ensure the quality, reliability, and interchangeability of these clamps within the UK and international markets.
W4 stainless steel non-perforated band worm drive hose clamp is one type of BS 5315 hose clamps. The material is all parts stainless steel 301/304
Features of BS 5315
The standard covers several essential aspects to guarantee clamp performance:
Materials:
Bands: Must be made from corrosion-resistant material, typically stainless steel (such as grades similar to 304 or 316) or carbon steel with a protective coating (e.g., zinc plating).
Housings and Screws: Must be similarly corrosion-resistant. For worm-drive clamps, the screw and housing are often made from plated carbon steel or stainless steel to match the band.
Design and Dimensions:
The standard provides precise dimensional tolerances for the band width, thickness, and the range of adjustment.
It defines the design of the housing and the engagement mechanism (e.g., the worm gear must engage smoothly with the band's perforations or slots).
Performance and Testing:
Pressure Resistance: Clamps must be tested to ensure they can retain a seal without failure or excessive deformation at a specified proof pressure.
Tensile Strength: The band and the housing must withstand a minimum tensile load without breaking or pulling apart.
Corrosion Resistance: Materials and finishes must demonstrate adequate resistance to corrosion, often verified through salt spray testing.
Common Applications
BS 5315 clamps are found in a wide range of industries requiring reliable hose connections, including:
Marine and Shipbuilding: Engine cooling systems, fuel lines, and bilge pumps.
Industrial Processing: Chemical, water, and fluid transfer lines.
Automotive: Coolant, fuel, and air intake systems (particularly in commercial vehicles and OEM manufacturing).
Heating, Ventilation, and Air Conditioning (HVAC): Connectors for ducting and piping.
