Gray: contains nickel, anti-seizing, anti-galling, and anti-corrosion, used for stainless pipes; Copper: contains copper granules and is certified as a thread lubricant but not a sealer; In Europe, the BSI standard BS-7786:2006 specifies various grades and quality standards of PTFE thread sealing tape.

The application of thermal pipe insulation introduces thermal resistance and reduces the heat flow. Thicknesses of thermal pipe insulation used for saving energy vary, but as a general rule, pipes operating at more-extreme temperatures exhibit a greater heat flow and larger thicknesses are applied due to the greater potential savings.

Self-amalgamating tape is a non-tacky silicone rubber tape that when stretched and wrapped around cables, electrical joints, hoses, and pipes combines or unites itself into a strong, seamless, rubbery, waterproof, and electrically insulating layer. [1] [2] Unlike many other polymers and fibers, it is heat-, sunlight-, and weather-resistant.
Detectable tape or Underground warning tape is a conductive tape typically applied over buried utilities made of non-conductive materials such as plastic, fiberglass, or cement. It is used because most utility location methods work best on conductive objects, and hence may easily miss structures made of non-conductive materials.
The effectiveness of a corrosion inhibitor depends on fluid composition and dynamics. Corrosion inhibitors are common in industry, and also found in over-the-counter products, typically in spray form in combination with a lubricant and sometimes a penetrating oil. They may be added to water to prevent leaching of lead or copper from pipes. [2]
