Assignment 3
Textbook Assignment:
Fluid Lines and Fittings, chapter 5, pages 5-11 through
5-21;
Valves,
chapter 6; and Sealing Devices and
Materials, chapter 7.
Learning Objective:
Recognize
uses, construction features,
operational characteristics and
procedures, functions, and
precautionary measures associated
with fluid power system
connectors.
QUESTIONS 3-1 THROUGH 3-4 CONCERN THE
USE OF THREADED CONNECTORS IN FLUID
POWER CIRCULATORY SYSTEMS.
3-1.
3-2.
3-3.
3-4.
The threads of newly threaded
pipe do not corrode if the
fittings cover all of the exposed
threading.
1.
True
2.
False
Pipe compounds prevent corrosion
and assist in the disassembly of
threaded joints.
1.
True
2.
False
Excess pipe compound that may
ooze inside lines does not
present problems if the compound
is compatible with the fluid in
the system.
1.
True
2.
False
The use of threaded connectors is
generally limited to low-pressure
systems.
1.
True
2.
False
IN ANSWERING QUESTIONS 3-5 THROUGH 3-7,
SELECT FROM COLUMN B THE TYPE OF
CONNECTOR TO WHICH EACH STATEMENT IN
COLUMN A APPLIES.
NOT EVERY CONNECTOR
IN COLUMN B IS USED.
3-5.
3-6.
3-7.
A. STATEMENTS
B. CONNECTORS
This connector is
1. Brazed
attached to the
piping by welding,
2. Flared
brazing, tapered
thread , or rolling
3. Welded
and bending
4. Flange
This connector
connects sub-
assemblies in some
fluid power systems,
especially in high-
-pressure systems that
use pipe for the fluid
lines
This connector is
commonly used for
joining nonferrous
piping in the pressure
and temperature range
where its use is
practical
3-8.
The fitting of a flared connector
should be made of material having
greater strength than that of its
sleeve and nut and of the piping.
1.
True
2.
False
