  • Certification of hose and fitting combinations
  • Root cause analysis and failure solutions
  • Proof of concepts in prototype testing

If you are interested in a service not listed please email us.

Each testing request receives our full attention ensuring you receive accurate information. To achieve this, we complete the following:

  • Provide a clear definition of specifications to be followed, and request scope
  • Execution of testing agreed upon between Dixon personnel and the customer prior to the start of testing
  • Full interpretation and failure analysis of results
  • Closing discussion with the customer, verifying the request has been completed to the satisfaction of request scope

We offer the following testing services:

Hydrostatic

Hydrostatic testing requires filling the valve/hose with water to purge air from the system, we then build pressure via an air-driven liquid pump. The amount of pressure and time involved is dependent on the requirements of the test, provided the pressure is within the maximum capacity of our system. If testing involves specific standards or specifications as per the test request, a copy of the document will be required to conduct testing.

Features:

  • Maximum pressure available: approximately 57,000 PSI
  • Digital pressure reading for increased accuracy
  • Complete test packet is available at the conclusion of testing
  • Automated pressure control

Heat/Elevated Temperature

Heat/Elevated Temperature testing is conducted with hydraulic oil using a through-flow process; meaning the fluid is pumped from a reservoir through the sample and back into the reservoir. The sample is set to the desired temperature rating and held/soaked for approximately an hour. Following the soak period, we then build pressure by choking off the flow to the reservoir. Each test is conducted to a specific time and pressure based on the test process requested. The test parameters are variable within the specifications of our equipment. If we are to follow a specific standard or specification as per the testing request, a copy of the document will be required to conduct testing.

Features:

  • Maximum temperature setting: 250°F (121°C)
  • Maximum pressure setting, continuous: 5000 PSI

Cycle

Cycle testing is performed using an air-driven liquid pump. The process involves building pressure and holding it for a set time frame, followed by dropping to no pressure for another allotted time frame. The process is repeated for a set amount of cycles. All variables (# of cycles, time at pressure, pressure, time at no pressure) can be adjusted to match the testing requirements, provided they stay within the capacity of the equipment. If testing involves specific standards or specifications as per the test request, a copy of the document will be required to conduct testing.

Features:

  • Maximum pressure setting: 600 PSI
  • Fully automated process runs continuously until the set amount of cycles are completed
  • Digital pressure reading for increased accuracy
  • Complete test packet is available at the conclusion of testing

Environmental Chamber

The Environmental Chamber is used to simulate various temperatures to determine its effect on fittings and/or hose assemblies. Little to no pressure is applied to the samples during this test. No catastrophic failures can occur in the chamber, as it may cause damage to the equipment. Fixtures can be designed to handle many size samples, provided they can fit into the chamber. If testing involves specific standards or specifications as per the test request, a copy of the document will be required to conduct testing.

Features:

  • Internal dimensions: 30" x 33" x 36"
  • Maximum temperature: approximately 400°F (204°C)
  • Minimum temperature: approximately -100°F (-73°C)
  • Current available range for testing: -40°F to 180°F ( (-40°C to 82°C)
  • Added components may be necessary to reach outside of the current range
  • Complete test packet is available at the conclusion of testing

Pull/Axial Force

Pull/Axial Force testing is conducted with no internal pressure on the sample. The setup pulls the sample along the centerline of the hose assembly using specially designed caps with eye bolts. The sample is pulled until failure occurs, then the load is stored and compared to the theoretical failure force based on the theoretical burst pressure failure as seen during;Hydrostatic Testing. If you are looking for a specified load as opposed to matching the theoretical burst pressure failure, the load can be set to override the comparison to the theoretical failure force. If testing involves specific standards or specifications as per the test request, a copy of the document will be required to conduct testing.

Features:

  • Maximum load capacity: 50,000 lbs
  • Hose sample size: 1'-2' free hose length (length of hose between fittings)
  • Fixtures: NPT threaded caps with eye bolts
  • Additional fixtures can be manufactured as needed
  • PLC controlled variable input and operation
  • Complete test packet is available at the conclusion of testing

Steam

Steam tests are run for the purpose of certifying a hose with our Crimp Boss steam fittings. All hoses need to be verified and approved through a group of select individuals before pursuing the hose as an option for our fittings. The testing process consists of samples experiencing steam exposure for an extended period with daily breaks. Then assess the samples ability to hold pressure afterward. Parameters of the test can be adjusted for specific standards per the request, provided the changes remain within the specifications of the equipment. If we are to follow a specific standard or specification as per the testing request, a copy of the document will be required to conduct testing.

Features:

  • Maximum pressure: approximately 200 PSI
  • Maximum temperature: approximately 390°F (199°C)
  • Standard test parameters: 23.5 hours at steam, 0.5 hours at rest, 720 hours at steam (total)
  • Follow up hydrostatic test done to assess the pressure retainability of hose samples
  • Complete test packet is available at the conclusion of testing

Air/Gas Under Water

Air/Gas Under Water testing identifies leaks which may not appear as easily as with a standard hydrostatic test. Using either shop air or nitrogen gas, a sample is placed into a container of water filled just enough to cover it. We look for any bubbles that may show up when pressure is applied. If testing involves specific standards or specifications as per the test request, a copy of the document will be required to conduct testing.

Features:

  • Maximum pressure: 500 PSI
  • Maximum hose sample size: 1'
  • Complete test packet is available at the conclusion of testing
