How Our Fire Hoses Are Manufactured

ACE fire hoses are meticulously manufactured in a dedicated facility that specializes in producing hose products exclusively for fire departments.

ACE Fire Hose Manufacturing process

Here's a simplified explanation of how a typical double jacket, rubber-lined fire hose is made:

Preparing the Yarn:

  • The hose jacket is woven using two types of yarn: warp yarns and filler yarns.
  • Warp yarns run lengthwise and provide abrasion resistance.
  • Filler yarns are wound in a spiral and give the hose strength to withstand water pressure.

Weaving the Jackets:

  • The warp yarns are placed on a creel and fed through a circular loom.
  • Filler bobbins with the filler yarn are set in the loom, and the weaving process begins.
  • The loom weaves the jacket by crisscrossing the warp yarns and trapping the filler yarn between them.
  • The inner and outer jackets are woven separately, and the outer jacket may be coated if needed.

Extruding the Liner:

  • Blocks of uncured rubber are fed into an extruder, which warms and presses the rubber to form a tubular liner.
  • The liner is then heated and vulcanized to make it strong and pliable.
  • A thin sheet of uncured rubber is wrapped around the outside of the liner using a rubber calendar.

Forming the Hose:

  • The jackets and liner are cut to the desired length.
  • The inner jacket is inserted into the outer jacket, followed by the liner.
  • Steam is injected into the hose to make the liner swell and bond with the inner jacket.
  • Metal end connections, or couplings, are attached to the hose to form a seal.

Pressure-Testing the Hose:

  • The hose is pressure tested to ensure its integrity and safety.
  • The testing is done at high pressure, typically 600-800 psi, and inspected for leaks and secure couplings.
  • After testing, the hose is drained, dried, rolled, and shipped to the customer.

This simplified overview highlights the key steps involved in manufacturing a fire hose, emphasizing the yarn preparation, weaving of jackets, extrusion of the liner, formation of the hose, and pressure testing to ensure quality and reliability.

This is how Ace Fire Defense was created.
