Proof Pressure Testing

Maximator Test’s Proof Pressure Test

What is a Proof Pressure Test?

Proof pressure testing is a type of nondestructive pressure test that is used to prove the durability of a given test sample in a controlled setting. The common requirements and standards for these tests are often two to six times the normal operating pressure of the test sample; samples that pass typically are not subject to deteriorating loads and therefore the component is not intended to be pressurized till leak or burst.

Benefits of Proof Pressure Testing at Maximator Test

  • Non-destructive test (designed to test parts without causing deformation)
  • Prove parts meet required ‘factor of safety’ standards
  • Confirm reliability and/or function of individual components
  • Confirm design margin of a part for production

Non-destructive testing such as proof pressure testing is common in productions that require every part to be tested prior to being distributed or used in an assembly. For example, aerospace and defense companies often have sensitive components that need to be tested prior to being used in the field.

In this case proof pressure testing may give a component the ‘seal of approval’ you need-indicating the component can endure the required workload and therefore it should be able to endure a pressure properly at or above normal operating pressure without deformation, bursting, or leaking.

Maximator Test will provide a comprehensive test report which includes:

  • An outline of the testing objectives
  • The tools and equipment used to conduct the test
  • The test setup and procedure; including photographs of how the setup was completed (when possible we can record the test run with video)
  • Results; including pressure plots (see sample below), data tables (or raw data), comments, and observations made while conducting the test
  • Failure photos showing failure locations
  • Calibration certificates

Maximator Test Proof Testing Service

Maximator Test conducts hydrostatic leak or burst testing at pressures up to 65,000 psi (4,500 bar) using water. We can also test up to 145,000 psi (10,000 bar) using oil and up to 14,500 psi (1000 bar ) using nitrogen. Burst testing is conducted using a plc controlled, monitored, and computer regulated test bench; featuring data acquisition at 50hz, calibrated pressure transducer, and protective safety features.

At Maximator Test we work hard to develop person relationships with our customers which helps us understand their goals and objectives. We do our level best to provide updates every step of the way to ensure you have the data you need in a timely fashion.

Pressure testing can be implemented to achieve a variety of goals. Pressure testing is especially common and useful for pressure vessels or high pressure components such as: pumps, accumulators, oil coolers, heat exchangers, prototypes, hydraulic cylinder, actuators, hydraulic rod seals, bladder, diaphragm, generators, transducers, pistons, fuel lines, fuel cells, fuel tubes, fuel injector body, injection systems, fluid ends, common rails, hp blocks, valves, hoses, piping, tubing, adapters, fittings, boosters, intensifier, caps, nozzles, nozzle holders, diesel units, diesel injection systems, clamps, hydraulic circuits, ultra high pressure units, pressure gauge testing, connectors, fixtures, bottles.

At Maximator Test we have worked with every major industry including: automotive, transportation (truck, rail, marine, etc…), aerospace, (or aeronautical), chemical, oil and gas, mining (quarrying, petroleum, hydraulic fracturing, coal), food and beverage, construction, computer, electronics, maintenance, health (hospitals and misc.), pharmaceutical, military, defense, plastics and rubber, sporting goods, manufacturing, fabrication (metal/plastic/polymer/other material) industries.
