LP (propane) hose assemblies and aircraft hose assemblies are produced in our large diameter hose cell (LDHC).  Both of these hoses require strict adherence to stringent coupling, testing, and record keeping procedures. 

  The hoses are cut to the length required and coupled to manufacturers specification.

  After the coupling procedure the hose are pressure tested to the specification required by the regulatory body responsible (UL, DOT, or API).

  After a successful test the coupling is engraved with a serial number.  This number is kept on file at IRPCO along with the customer identification and date information.

  All of this information is transferred to the certification document which is packaged with the hose itself.  A copy of the certification document is also sent with the invoice and another copy is retained in the IRPCO files.  This information is also stored electronically in the IRPCO system.  Redundancy here insures that the certification information is available if needed.
