PVC
& CPVC Flanges and Flange Fittings
All PVC and CPVC flanges and flange fittings produced by LASCO
comply with the pressure-temperature ratings, materials,
dimensions, tolerances, markings, testing, and methods of
designating openings for steel pipe flanges and flange fittings
in sizes NPS, 1/2 through NPS 24 as specified in ANSI b16.5. |
Pressure Rating of Plastics
In the engineering of thermoplastic piping systems, it
is necessary to have not only a working knowledge of piping
design but also an awareness of a number of the unique properties
of thermoplastics. |
Pressure Rating Of PVC & CPVC Plastic Piping For Water At
Elevated Temperatures
The factors given in the attached table are suggested
for use in determining the pressure ratings for water and PVC or
CPVC plastic piping at temperatures above the standard
temperature. |
PVC at Low Temperatures
To the best of our knowledge, and my 20+ years of
experience, the PVC pipe and fittings can serve satisfactorily at
low temperatures. Although, the published information is limited
on cold temperature performance. |
Thermal Expansion
Allowance for thermal expansion and contraction should
be provided to prevent undue stress in the piping and fitting
systems. Any additional stress caused by temperature changes can
cause unexpected failures. |
Water Hammer Calculator
This calculator show the surge pressure generated within a
system based on velocity change, pipe run, material and pipe
sizing. The intent of this calculator is to assist in informing
users, engineers and others. Interpretation, use and application
are a function and responsibility of the user. |
Flow Velocity & Head Loss Calculator
This calculator generates information on the friction head
loss of various piping, sizes, materials and flow rates used in
water distribution systems. The intent of this calculator is to
assist in informing users, engineers and others. Interpretation,
use and application are a function and responsibility of the
user. |
Irrigation Energy Esitmator
The "U.S. Department of Agriculture Energy
Estimator for Irrigation," available online, evaluates
opportunities to improve irrigation energy and water
efficiency. Growers can visit the
website, enter information about their irrigation system and
receive an analysis of potential changes that can result in
energy and/or water savings. The
program uses data about the type of irrigation system, crop,
power source, pressure, energy price and scheduling to help
reduce your energy costs.
The estimator is available at http://ipat.sc.egov.usda.gov/.
