asphalt transfer hose

Hose Master makes solutions for tar and asphalt.

Hose Master hosing solutions are available from Sudbury International Engineered Products Limited. The lineup includes hoses for transferring tar and asphalt in road and bridge work. This is a hazardous job due to fume exposure. Hose Master offers innovative solutions – plus advice on selecting the right asphalt transfer hose.

Sudbury International supplies both rubber and metal Hose Master units for this application, but customers should consider certain limitations.

Threaded or flanged connections

Commonly used in this area, rubber hoses are made from elastomers that resist the media and are typically rated to a maximum working pressure of 150 pounds per square inch and a maximum temperature of 150-175 degrees Celsius. A rubber hose is cost-efficient, but before picking one as a tar or asphalt transfer hose, customers should consider these aspects:

  • Temperature/pressure combinations. Maximum pressure and temperature must be verified, since derating factors may apply in high-temperature operations.
  • Vacuum service. Not every tar or asphalt transfer hose is rated for vacuum or suction.
  • Hose cleaning. Hoses should be cleaned after each use.
  • Coupling retention. Interlocking-type clamps can avoid potentially hazardous coupling separation.
  • Weathering or cracking: Users should inspect rubber hoses for cracking, damage, or degradation before every use.

Metal hoses by Hose Master for tar or asphalt transfer come in two styles from Sudbury International – interlocked and corrugated. Also known as stripwound hoses, interlocked units must be handled properly to prevent damage. They are durable and weather-resistant, but can leak if twisted, and they should not be used for less viscous media for the same reason. Users should drain these hoses thoroughly following every use.

Corrugated metal hoses for tar/asphalt transfer are gas-tight, resist weathering and high temperatures, and provide positive fitting retention. But the corrugations allow media to collect in the hose, which can harden after cool-down and damage the hose when it is flexed. Hose Master recommends storing these hoses in heated cabinets if practical, to prevent media hardening.

Hose Master has extensive experience in creating metal hose assemblies designed specifically for safe, efficient tar and asphalt transfer.
