Chapter 11 Flashcards
It is a means of connecting pipe ends to ensure that two pipes can be joined together and install a pipeline of any length.
PIPE JOINT
On joints and connections of pipes and fittings in the plumbing system shall be required to ensure gastight and watertight connections.
PRESSURE TEST
Types of Joints
CAULKED JOINT
THREADED JOINT
WIPED JOINT
SOLDERED AND SWEAT JOINT
FLARED JOINTS
CEMENT MORTAR JOINTS
BURNED LEAD JOINTS
ASBESTOS CEMENT SEWER PIPE JOINT
SOLVENT CEMENT PLASTIC PIPE JOINTS
MOLDED RUBBER COUPLING JOINTS
BRAZED JOINT
A joint in which suitable material is neither poured or compressed by the use of tools into the annular space between a bell or hub.
CAULKED JOINT
A type of joint where pipes are connected by screwing with the help of _____ provided for each pipe.
THREADED JOINT
Soldering process involves mechanically working or wiping the joint.
WIPED JOINTS
Soldering a pipe joint or sweating a pipe is accomplished by heating a copper fitting with a propane torch until the fitting is just not enough to melt metal solder.
SOLDERED AND SWEAT JOINT
An alternative solder-type joint that are mechanically separable and doesn’t require an open flame.
FLARED JOINTS
Made of Cement base material such as portland cement or mortar mix, and are most commonly used in plumbing applications.
Except for repairs and connections.
CEMENT MORTAR JOINTS
Type of joint for lead piping which shall be lapped and the assembly be fused together to form a uniform weld as thick as the lead.
BURNED LEAD JOINTS
Shall be sleeve coupling of the same composition as the pipe or of other approved materials.
ASBESTOS CEMENT SEWER PIPE JOINT
Common jointing method for plastic pipe and fittings systems.
SOLVENT CEMENT PLASTIC PIPE JOINTS
Rubber expansion joints are made to safely absorb vibrations, like those caused by pipes expanding and contracting because of temperature.
MOLDED RUBBER COUPLING JOUNTS
It is important to note the melting point of the parent material should be higher than the filler material to avoid melting the parent metal.
Another Q.
Work pieces are heated but below their melting point.
BRAZED JOINT
BRAZING
Types of Brazing
TORCH BRAZING
INDUCTION BRAZING
FURNACE BRAZING
RESISTANCE BRAZING
it uses a handheld gas torch to heat the base material, once heated enough, the filler material is introduced into the joint allowing it to melt.
TORCH BRAZING
It is similar to torch brazing; however, it uses induction heating.
INDUCTION BRAZING
It is used mostly in industrial manufacturing plants where filler material is placed across the metal at the desired joint.
FURNACE BRAZING
It joins to metals using a low temperature interface metal called “brazing alloy”.
RESISTANCE BRAZING
Welding - to join pieces need to be heated till their melting point.
WELDED JOINT
Types of Welded joints
BUTT WELDED JOINT
SOCKET WELDED JOINT
PRESSURE-LOCK TYPE CONNECTION
SHIELDED COUPLING JOINTS
Any fitting or connection which has an enlargement, chamber or recess with a ledge, shoulder or reduction of pipe area, that offers an obstruction to flow through the drain is prohibited.
