Gas and oil industry flares are critical in preventing dangerous pollutants and hydrocarbons from entering and polluting the atmosphere.

A flare stack, is a gas combustion device used in industrial plants such as petroleum refineries, chemical plants, and natural gas processing plants as well as at oil or gas production sites having oil wells, gas wells, offshore oil and gas rigs, and landfills.

In industrial plants, flare stacks are primarily used for burning off flammable gas released by pressure relief valves during unplanned over-pressuring of plant equipment. During plant (or) partial plant startups and shutdowns, flare stacks are also often used for the planned combustion of gases over relatively short periods.

A guy-wire, guy-line, or guy-rope, also known as simply a guy, is a tensioned cable designed to add stability to a free-standing structure. They are used commonly in flare stacks, ship masts, radio masts, wind turbines, and more.

Guy wires are constantly under tremendous stress with additional stress caused by their constant motion.

These wire ropes that are helping to support these structures are continuously exposed to a myriad of hostile elements throughout the entire life of their service.

For this reason, all wire rope and bridge strand manufacturers agree that every maintenance program needs to include regular inspection services including lubrication, and proper re-tensioning in regular cycles of approximately every 18-24 months.

Infraspect offers an efficient and safe manner to professionally inspect and evaluate all guy wires with our remotely operated wire rope inspection service using RopeScan®.

RopeScan® is a lightweight portable, wireless magnetic flux leakage inspection services robot that locates loss of metallic area inside the individual metal strands either exposed or right through a High Density Polyethylene (HDPE) sheathing.

A guy-wire, guy-line, or guy-rope, also known as simply a guy, is a tension cable designed to add stability to a free-standing structure. Wire rope terminology is shown in the figure to the right. Wire rope terminology is shown here.

Wire – Single wire
Strand – Bunch of wires
Core – Bunch of wire placed center
Rope – Core surrounded by a number of strands

Different configurations of wire ropes are shown in the figure. These ropes are designed and used for various applications. Infraspect’s RopeScan® was designed to peer through the steel strands to locate the loss of metallic (corrosion) within the steel.

By determining loss of metallic area early in the life of a guy wire or any wire rope then on further inspections, the inspector can monitor the deterioration progression over time knowing when to replace a wire rope before it is too late.
