18
Q

Rigid piping is bent using minimum bend radius and must

A

maintain minimum 75% original tube outside diameter

19
Q

Adel Clamps are used to

A

secure lines

20
Q

To help absorb stress from vibrations

A

tubing should have at least one bend

21
Q

What are flex lines used on

A

areas with moveable components

22
Q

Flex line parts

A

Lay Line, outer Layer, reinforcement layer, inner liner

23
Q

Inner Liner

A

carries content
most not be porous to hold the fluid
mist be compatible with fluid being xmited
must have smooth surface to reduce friction
must be flexible in all temperatures

24
Q

Reinforcement Layer

A

used for strength
made of cotton/ polyester fabric/ carbon steel or stainless steel braid
under high pressure reinforcement materials will expand in diameter and contract in length

25
Q

Outer Layer

A

protects line
made of stainless steel braids or rubber impregnated fabric. fire resistant cover for fluid lines in areas with high temperature

26
Q

Diameter of flex lines

A

matured in 1/16

27
Q

A

Synthetic rubber used with petroleum based fluids

29
Q

Buna-N

A

Synthetic rubber used to carry petroleum based fluids

30
Q

Butyl

A

Synthetic rubber used primarily for hydraulic fluids including skydrol

31
Q

Teflon

A

has large temperature range (-65 to +450) it is compatible with all fluids (petroleum and synthetic)

32
Q

Lay Line

A

consists of yellow, red or white stripe
contains a MIL spec number
contains Mfg name and or symbol

33
Q

bends which are too sharp

A

reduce the bursting pressure

34
Q

Flex lines should have ___% flex for expansion

A

5-8

35
Q

What is the torque equation

37
Q

What is TA

A

Torque at fastener

38
Q

What is A

A

Length of adapter

39
Q

What is L

A

Length of torque wrench

40
Q

For low pressure lines strip the outer layer from the line

A

3/4 the length of the ferrule

41
Q

Flex hoses are clamped between

A

Socket and the nipple

42
Q

When the fabrication of the hose is completed there should be

A

1/32 -1/64 between the ferrule and the bottom of the nut
