158Asbestos Cement Pipe (ACP)
Common water distribution pipe, notice that both pipes have been cut with a power saw. You are
not allowed to cut this type of pipe with a power saw, because it will spread the Asbestos.
Wetting agents may be applied with garden sprayers or hoses. Garden sprayers are hand-held,
portable, and have a one- to five-gallon capacity. Water hoses are usually attached to a faucet tap,
fire hydrant or water tank. Generally, the hose has a nozzle attached which spreads the water
stream so that a fine mist is created.
Asbestos-Cement Products
Asbestos-cement products (such as transite) are commonly used for duct insulation, pipes, and
siding. Being a Category II nonfriable ACM, asbestos-cement products need to be removed prior
to demolition if they have a high probability of becoming crumbled, pulverized, or reduced to powder
during demolition activities. EPA believes that most demolition activities will subject such Category
II nonfriable ACM to the regulation.

Heat Stability
Asbestos will maintain its structural integrity at temperatures well above 800 F. The melting point
is at about 2800 F
Thermal Insulation
The fibers have a relatively large surface area, along with numerous pores, and cracks. This
allows for a low heat transfer. This makes it useful as an insulator in homes and machinery. The
large surface area also absorbs water making it practical as pipe insulator to prevent sweating.
Chemical Resistance
The amphiboles are resistant to aqueous media and chemical attack. They also show high
resistance to acids. This makes this class of asbestos useful for battery packing. Chrysotile is
significantly less resistant to chemical destruction.
