PITT-CHAR XP ®

FIRE PROTECTIVE COATING

PPG INDUSTRIES, INC. 2002

WHAT IS FIREPROOFING?

Any barrier which blocks the rate of temperature rise of a given substrate during a fire. Typical forms of fireproofing are:

Concrete & Gunite Low Density Cements Insulation Materials

Dry Fix Sprayed Fibers

Intumescent Coatings


WHO ARE THE MAIN USERS?

Refineries

Petro-chemical Plants

Gas Processing Plants

Offshore Production Platforms

Commercial Buildings

Manufacturing

Pharmaceuticals PPG INDUSTRIES, INC. 2002

WHY USE FIREPROOFING?

To protect investment

To reduce down time

To protect lives

To meet government regulations

To meet insurance requirements

To limit liability

TYPICAL FIRE RATINGS OFFSHORE

Structural Steel Certified Hp/A programs to tailor the amount of fireproofing to the size of steel and limiting steel temperature required. Bulkheads & Underdecks

“A Type” Fire environment is cellulosic. Structure requires no passage of smoke, gas or flame for 1 hour. In addition the number shown after the “A” indicates the number of minutes the backside temperature can not rise above 139C plus ambient or a max of 180C. “H Type” Fire environment is hydrocarbon. Structure requires no passage of smoke, gas or flame for 2 hours. In addition the number shown after the “H” indicates the number of minutes the backside temperature can not rise above 139C plus ambient or a max of 180C. For Stress Skin type bulkheads structural limit should be 400C after 2 hours.

JET FIRE TEST DESCRIPTION

Heat Flux of 300 - 350 Kw/m2 Fuel Source of Propane Nozzle Size 17.8mm [0.70”] Flow Rate .03 Kg./second [0.7 LB../second] Backside limiting temperature of 400 C


JET FIRE TEST RESULTS

Tested in both full and sub-scale environments at Spadeadam Buxton & SWRI Tested to the Interim Jet Fire Standard using both the box with central web and 203mm tubulars Protection times of 30 to 120 minutes at a maximum steel temperature of 400 C


TYPICAL FIRE RATINGS ON-SHORE

UL-1709 - Underwriters Laboratory column test designed to simulate a hydrocarbon type fire. Also has a mandatory weathering program to simulate exposure to an industrial environment. UL-263 - Underwriters Laboratory fire test for materials used in building construction. Test can be run on columns, beams, walls, floors and roofs. Simulates burning of standard cellulosic type building materials. Sometimes referred to as ASTM E-119.

EXPLOSION TESTING

PITT-CHAR XP® has been subjected to 1.8 bar in actual explosion testing with no cracking or disbonding. Because of its flexible nature PITT-CHAR XP® can move with the steel allowing it to take overpressures well into the plastic region of the steel. PITT-CHAR XP® is also less likely to be damaged by flying rubble.


EXPLOSION TEST DESCRIPTION

Steel panel PFP coated on blast side

60 Kg. charge of ammonium nitrate & fuel oil mixture

Overpressure up to 1.8 bar

Duration 7.5 milliseconds


EXPLOSION TEST RESULTS

PITT-CHAR XP has been subjected to actual not just simulated explosion testing In actual overpressures out to 1.8 bar PITT-CHAR XP showed no cracking, disbonding or loss of fire protection With its 19.4% elongation PITT-CHAR XP will remain intact long after the steel has been permanently deformed


CONTRACTOR PROGRAM

PITT-CHAR XP® is only applied by trained certified applicators. Each certified applicator is required to have PPG trained personnel and PPG approved equipment
