TUBING VS PIPE
Standard fluid line systems, whether for simple
household use or for the more exacting requirements of industry, were for many
years constructed from threaded pipe of assorted materials and were assembled
with various standard pipe fitting shapes, unions and nipples. Such systems
under high pressures were plagued with leakage problems besides being
cumbersome, inefficient and costly to assemble and maintain. Therefore, the use
of pipe in these systems has largely been replaced by tubing because of the
many advantages it offers.
Major
Advantages of Tubing vs. Pipe
1. Bending Quality - Tubing
has strong but relatively thinner walls;
is easy to bend. Tube fabrication is simple.
2. Greater Strength - Tubing
is stronger. No weakened sections from reduction
of wall thickness by threading.
3. Less Turbulence - Smooth bends
result in streamlined flow passage and less pressure drop.
4. Economy of Space
and Weight - With its better bending qualities
and a smaller outside diameter, tubing saves space and permits working in close
quarters. Tube fittings are smaller and also weigh less.
5.
Flexibility
-
Tubing
is less rigid, has less tendency to transmit vibration
from one connection to another.
6.
Fewer
Fittings - Tubing bends substitute
for elbows. Fewer fittings mean fewer joints,
fewer leak paths.
7. Tighter Joints -
Quality
tube fittings, correctly assembled, give better
assurance of leak-free systems.
8.
Better
Appearance - Tubing permits smoother
contours with fewer fittings for a
professional look to tubing systems.
9.
Cleaner
Fabrication - No sealing
compounds on tube connections. Again no
threading; minimum chance of scale, metal chips, foreign particles in system.
10.
Easier Assembly and Disassembly - Every tube connection
serves as a union. Tube connections can be reassembled repeatedly with easy
wrench action.
11.
Less
Maintenance - Advantages of
tubing and tube fittings add up to
dependable, trouble-free installations.
