PIPING MATERIALS

Question 1

MOST COMMON,

LOW PRESSURE FOR GAS, WATER, AIR, OIL OR OTHER FLUIDS

Answer 1

CS - CARBON STEEL

Question 2

RESISTANCE TO CORROSION
OUTDOOR PIPES SUBJECTED TO HARSH WEATHER AND CORROSIVE ENVIRONMENT
HIGH PRESSURE APPLICATION
FOOD PROCESSING

Answer 2

SS - STAINLESS STEEL

Question 3

SUBJECT TO CORROSION WHEN EXPOSED TO CERTAIN CHEMICALS

LOSSES STRENGTH AS IT HEATS UP

Answer 3

AL - ALUMINIUM

Question 4

USED FOR COOL WATER AND DRAIN LINES

Answer 4

PVC

Question 5

CAN BE EASILY CUT IN THE FIELD
PARALLEL CABLE
END DOES NOT CONNECT

Answer 5

SELF REGULATING - SR

Question 6

2 TYPES OF MINERAL INSULATED CABLES

Answer 6

1 AND 2 CONDUCTORS

Question 7

This is the maximum temperature the cable will ever be exposed to either from ambient sources, process temperatures, or combination of these and contribution from the cable itself. If the
maximum exposure temperature is exceeded, the insulation on the cable will break down.

Answer 7

Maximum Exposure Temperature

Question 8

: How high a temperature the cable can be used to heat a vessel or
pipe up to for temperature maintenance

Answer 8

Maximum Operating Temperature

Question 9

CABLE THAT HAVE Maximum Operating Temperature OF 500-600 DEGREES CELCUIS

Answer 9

MI = Mineral Insulated Cable

Question 10

is a Parallel Cable

Ends do not connect, they are an OPEN CCT

Answer 10

SR = Self Regulating Cable

Question 11

is filled with sealant and slid onto the end of the staggered busses so the ends do not
accidentally short out.

Answer 11

End kit

Question 12

has a very high melting point (it can withstand a lot of heat without breaking down)

Answer 12

Magnesium Oxide (MgO)

Question 13

is a good insulator in terms of electrical resistivity, but a poor insulation for heat. Therefore, it’s
perfect for a heating cable!

Answer 13

MgO

Question 14

allows for entry into the power supply point

Answer 14

Pigtail

Question 15

is a length of Cable that is included in a pre-fab length from the manufacturer.

Answer 15

Pigtail

Question 16

;This point (or enclosure) contains terminal blocks

Answer 16

Power Supply Point

Question 17

Supplies power to heating cable but outside remains cold to the touch.Must be long enough for a drip loop

Answer 17

Cold Lead

Question 18

this is the section that heats up. 1 Conductor Cable arrangements are used on smaller diameter pipes

Answer 18

Heating Cable

Question 19

A loop of cable that allows moisture to drip away from the heating cable
also provides strain relief so as little stress as possible is placed on the HOT/COLD Joint

Answer 19

Drip loop

Question 20

A loop of a single cable both ends in single pigtail.

Answer 20

Arrangement 1

Question 21

used when you require a lot of heat (HIGH TEMPERATURE) in an area.

Answer 21

2 Conductor Cable Sets

Question 22

RTD

Answer 22

Resistive Temperature Device
