TECHNICAL DATA FOR SHARKBITE
®
PEX PIPE (CONT’D)
The SharkBite PEX Pipe is design certified to ASTM F-876, F-877, UL 1821,
CSA B137.5 standards, and is listed to the NSF standards 14 and CSA B137.5
standards for use in potable water systems.
Since SharkBite PEX Pipe will expand and contract during temperature
changes, please allow slack when running the pipe through the building.
SharkBite PEX Pipe will expand and contract at a rate of approximately 1"
per 100 feet of Pipe for each 10°F change in temperature (see equation
below). We recommend that osets and expansion loops be used as ways to
compensate for expansion and contraction. The change of pipe length due to
temperature increase can be calculated as follows:
160psi @ 73.4°F (23°C)
100psi @ 180°F (80°C)
80psi @ 200°F (93°C)
ΔL = α(L • ΔT)
where: ΔL = change of length (inches)
ΔT = change of temperature (°F)
L = original pipe length (feet)
α = coecient of linear expansion = (8 x 10-5 @ 68°F)
EXAMPLE:
ΔT = 10°F L = 100' ΔL = 0.08"
