Companies provide align shafts, pumps, motors, drives, compressors, components, rotating machines, or equipment. Aligning a new drive or motor's shaft properly to the shaft of a pump or compressor is important in assuring no vibrations will occur. Bearing failure can result when shafts are misaligned. Radial alignment, angular alignment, vertical displacement, and horizontal displacement are adjusted through equipment or component positioning with shims, leveling or chocking compounds, surveying instruments, laser alignment tools, and level & plumb checkers.
Acoustic testing services include the evaluation of the condition of materials, products, and equipment; acoustic analysis of signals from analog or digital recording media or products; and investigation of the effects of noise including ultrasonics and infrasonics, on people, components, materials, or products.
Acoustic emission testing is a nondestructive test (NDT) method for determining or monitoring material or structural integrity based on the release of energy detectable by analysis of the emission frequency and amplitude. Particle impact noise detection (PIND) is used to find loose internal components or debris within a device or product undergoing a simulated vibration or shock test.
Companies balance wheels, shafts, and other rotating machine components. Imbalance in rotary parts can cause severe vibrations leading to equipment damage and unplanned production shutdowns. Dynamic and static methods are used to measure and balance machinery components and systems. The actual balancing of shafts, wheels or parts is accomplished by adjusting the distribution of mass through the addition of weights or milling off of material.
Companies test or inspect for corrosion's effects and for corrosion resistance. Corrosion is a chemical or electrochemical reaction between a material, usually a metal, and its environment. It causes deterioration of the material and its properties. Laboratory corrosion tests include immersion tests in corrosive solutions, and salt spray or fog tests. Field corrosion inspection or testing includes the following: thickness changes and weight loss, and process water compositional changes using ultrasonic, eddy current, mechanical gaging, coupon tests, chemical analysis, and other techniques.
Companies gage dimensional parameters or provide metrology services. Gages or metrology instruments used can include micrometers, plug gages, ring gages, universal gages, coordinate measuring machines (CMM), profilometers, optical comparators, laser micrometers, depth gages, height gages, go-no go gages and well as other mechanical, optical, pneumatic, and electronic gages. Gaging may be performed on a new component from a production line, prototypes, or for the reverse engineering of components. These tests can be performed before or after other dynamic or environmental tests.
Companies offer electrical and electronic testing and inspection services, including: dielectric, conductivity, electrostatic discharge, insulation resistance, resistivity, or high voltage surge.
Pressure and flow testing includes pressurized liquid or gas exposure, hydrostatic burst tests, flow tests, and evaluation of thermal (icing) effects on fluid systems. Pressure and flow tests are commonly used to evaluate hydraulic, pneumatic, or gas handling equipment.
Failure analysis is the evaluation of a product and product failure to determine the underlying cause of the failure. Failure analysis results are used to correct design flaws.
Troubleshooting is diagnostic or corrective maintenance performed to correct an existing problem. This differs from preventive maintenance, which is performed proactively in order to prevent system problems. Failure mode and effects analysis (FMEA) is a specialized methodology for analyzing failures.
Companies inspect, gage, and determine part or product geometry attributes such as roundness, straightness, flatness, waviness, squareness, warp, bow, concentricity, or other form parameters.
Company provides load or capacity testing of batteries, battery banks or systems, power supplies, UPS systems, engines, motors, or other power systems.
Oil analysis and fluids testing encompasses the evaluation of oils, fuels, lubricants, coolants, greases, EDM fluids, transformer insulating oils, and other industrial fluids using a variety of tests. Testing can include ferrography, viscosity (stokes or kinematic), elemental analysis, spectroscopy (FT-IR, GC-MS), crackle, oxidation, foam, determination of drop point, % sediment, particle count, dielectric strength, specific gravity, surface tension, water content, pour point, cloud point, and other specific fluid properties effecting machine performance or equipment operation.
Ferrography is the separation and analysis of metallic (ferrous or ferromagnetic) wear particles from a lubricant or fluid. Ferrography or wear particle analysis is used to monitor lubricant or machine condition.
Companies test physical properties such as burst strength, cut and puncture resistance, life cycle and durability, pneumatics, and hydraulics, Rockwell hardness, tensile strength, and elongation.
Testing for thermal properties or characteristics includes conductive heat resistance, radiant protective performance (RPP), thermal conductivity, heat capacity, thermal protection, or insulation properties using thermal exposure simulation, icing, and high temperature exposure or other thermal tests.
Reliability or robustness measures a system's invulnerability to potentially corrupting influences. This testing is especially important when components in a system fail.
Companies use thermal imaging, thermography, or infrared cameras to inspect and identify hot spots, heat leakage or overheating components in buildings and equipment. Thermography can identify overheating in circuit breakers or load centers, and damaged or worn bearings. Thermal imaging is used to locate faulty or missing insulation or refractories around furnaces, ovens, building walls or heating ducts, steam lines, and other thermal processing equipment.
Companies offer vibration analysis or testing services. Vibration testing may include bounce, sine, or random vibration testing services. Bounce tests are often used to simulate certain transportation conditions. Vibration analysis is used to detect and assess the condition of product, rotary machines, and other equipment.
Companies provide visual or video inspection of components, products, equipment, pipeline, pressure vessels, weld, process lines, machinery installations, and other applications.
