PIPE
This pipe must be heavy enough to hold continuous pressure without
rupture, and all connections must be leak proof. This pipe tends to be of a
smaller diameter
PRESSUREPIPE
Carries waste and soil water away from the fixtures and the building by
the force of gravity. It is typically lighter weight with thinner walls than
pressure pipe, and joints do not need to be as tightly sealed because
there is no pressure exerted on them.
generally larger in size than pressure pipe to allow for free gravity flow
DRAIN, WASTE AND VENT(DWV)PIPE
the most popular water supply pipe material.
It is also used in water space heating (hydronic) systems, air conditioning
and refrigeration systems, sanitary drainage, and natural gas and liquid
petroleum gas piping.
COPPER PIPE AND TUBING
copper pipe is Faster installation in comparison to ___________ or brass
treaded steel
available as either rigid (hard temper) or flexible (soft temper).
is used primarily for underground water service in water supply
systems.is color coded in GREEN for quick visual identification.
TYPE K
available in either hard or soft temper and in coils (soft temper only)
and straight lengths much like Type K.is color coded BLUE.
This type of tubing is most popular for use in water supply systems.
TYPEL
is made in hard temper only and is available in straight lengths of 12
and 20 ft (3.7 and 6.1 m).
It is used for branch supplies where water pressure is not too great,
but it is not used for risers and mains.
is color coded RED.
used for chilled water systems, exposed lines in hot water heating
systems, and drainage piping.
TYPE M
is the thinnest copper tube and is used in non pressure applications.
It is made in hard temper only and is obtainable in straight lengths of
20 ft (6.1 m).
DWV (DRAIN, WASTE, VENT)
.
Red brassing pipe consist of approximately _____ copper and ___ zinc, is used as
water supply piping
85%, 15%
Is threaded for fitting connections, but this requires thicker walls to
accommodate the threading, making installation and handling more
difficult than for copper.
has relatively higher total cost, installed on the job, limits its usage
RED BRASSPIPING
used to transport liquids and gasses, such as oil, water, and gas,
underground and above ground.It is typically sold in lengths of 21 ft.
When steel pipe is forged, a black oxide scale forms on its surface
that gives it a dull black finish, and as a result it is called black pipe.
STEELPIPE
Durable and widely used for
industrial and high-pressure
systems.
CARBON
Corrosion-resistant, used
for hygienic applications
like food processing.
STAINLESS
Coated with zinc to prevent rusting; often used in water systems.
GALVANIZED
is the type most commonly used for water supply and fire suppression
sprinkler systems.
The most commonly used wrought-iron pipe is galvanized.
LIGHTWEIGHT WROUGHT-IRON PIPE
The _ coating adds extra corrosion resistance
zinc-galvanized
Is commonly used in gravity building and storm drain/sewer systems
CAST IRON PIPE
Cast iron pipes and fittings are limited to ________
gravity pressure systems
Cast iron pipe are connected using two methods: ______________ that are joined by sliding the spigot into the hub; and the
__________ that is connected with a rubber gasket and
screw-type clamp that is similar to a hose clamp.
hub (female end) and spigot
(male end), no-hub connection
Rarely used today due to health concerns but historically used for water
pipes (Lead is a toxic metal that can build up in the body and cause
health problems)
Lead
Used in laboratories for transporting aggressive chemicals. Often used
for their chemical resistance and transparency
Glass
Flexible pipes often used for temporary or flexible connections. Often found
in industrial settings where equipment layouts are complex and tight spaces
require flexible connections, such as in the oil and gas industry
RUBBER
Thermoplastic pipe are sometimes referred to simply as _______
plastic pipe
