Pipe liners are used to prevent leakage or infiltration in pipes and piping systems.

Resurfacing, recoating and refinishing services alter or restore damaged coatings and surfaces to a usable condition.

Current sense transformers are used to detect and measure current. There are two basic types of products: switch-mode transformers for power conversion applications, and precision-measurement transformers for instrumentation applications.

RF transformers transfer energy from one circuit to another by electromagnetic induction. Typically, they are used to increase or decrease voltage as it passes from one side through the other.

Epoxy adhesives are chemical compounds for joining components. They require clean surfaces and are valued for their toughness and resistance to chemical and environmental damage

Circuit protection devices are used to protect electronic components from unwanted transients such as current and voltage surges, electrostatic discharge (ESD), lightning, spikes and other signals that can imperil the operation or damage the component

Heat treating services perform thermal treatments to modify the properties of metals and metal alloys. Common processes include annealing, austempering, case hardening, conventional hardening, homogenizing, hot isostatic pressing (HIP), martempering, normalizing, precipitation hardening, shot peening, solution treating, spheroidizing, stabilizing, and stress relieving.

Heat transfer fluids, thermal oils, circulating coolants, and heater liquids are used to carry thermal energy in process heating and machine cooling applications.

Optical mirrors have a smooth, highly-polished, plane or curved surface for reflecting light. Usually, the reflecting surface is a thin coating of silver, or aluminum on glass.

Rechargeable batteries or secondary batteries contain active materials that can be regenerated by charging. When the energy produced by rechargeable batteries drops below optimum efficiency, secondary batteries may be recharged in a couple of ways, depending upon their construction. 

Crushers and mills are used to reduce chemicals, materials or other products to a desired particle or aggregate size range.

Protective liners and lining systems protect an underlying surface from corrosion, wear, erosion, heat or fire. They may also provide leak protection or fluid containment.

Electron microscopes use a focused beam of electrons instead of light to "image" the specimen and gain information as to its structure and composition.

Primary refrigerants use a thermodynamic or adiabatic process (evaporation-condensation cycles) to remove heat and cool a region. Secondary refrigerants such as antifreeze liquids provide cooling solely through heat transfer

Disposable primary batteries are replaced once the energy supply is depleted. Their energy is produced when the materials within the battery react and are exhausted.
