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.
