Corrosion removes pipe wall.
Repainting without solving rust in pits
only hides the next failure.

Measure. Repair. Convert. Protect.

Z801 FastSteel being applied to restore lost wall profile in a corroded pit.

01 / REPAIR

Z801 FASTSTEEL

Fast-setting, steel-filled repair restores lost profile in approved local pits.

Rusted pipe steel after Z704 RUSTEX-NMB conversion, blue-black where converted.

02 / CONVERT

Z704 RUSTEX-NMB

Converts residual rust. Treats salt and acid traces. Bonds the topcoat.

Freshly topcoated pipework in a process plant.

03 / PROTECT

SELECTED TOPCOAT

Keeps moisture, salts, acids and dirt away from repaired steel.

WHY Z704 IS FIRST IN THE WORLD

TRIARMOR TECHNOLOGY

WORLD’S FIRST MULTI-CHEMISTRY, NANO-MOLECULAR ADHESION RUST CONVERTER

01 / RUST IN PITS

CONVERTS DEEP

Complementary reactions reach residual rust deep inside prepared pits.

02 / SALT + ACID

TREATS RESIDUAL TRACES

After washing, treats rust beneath residual salt and acid traces and seals the interface.

03 / TOPCOAT

BUILDS COVALENT BOND

Nano-molecular coupling bonds converted steel to the selected topcoat.

BLUE-BLACK = CONVERTED  /  ORANGE = RECOAT

WHY PIPELINE REPAINTING FAILS

A large-bore pipeline pitted and scaled along its whole run.

01 / PITTING

PITTING MEANS PIPE WALL ALREADY LOST.

Pits hold rust, moisture, salt and acid-fume residue. An ordinary coat can hide the pit while corrosion continues below.

Z801 / RESTORES LOST PROFILE IN APPROVED LOCAL PITS

Congested plant pipework that cannot be blasted or ground clean.

02 / SURFACE PREPARATION

CANNOT BE DONE PROPERLY.

Live lines, spark restrictions and height leave rust behind. 75% of coating failures begin with poor preparation.

Z704 / CONVERT WHAT REMAINS

Paint peeling and blistering off weak rust on a pipe surface.

03 / TOPCOAT ADHESION

POOR BOND. EARLY FAILURE.

Paint on weak rust peels and blisters. Z704 bonds converted steel to the topcoat.

Z704 / BUILD THE BOND

ONE COMPLETE PIPELINE SYSTEM

Z801 RESTORES LOST PROFILE. Z704 CONVERTS AND BONDS. THE TOPCOAT MATCHES THE EXPOSURE.

WHERE PIPELINES KEEP CORRODING

Cooling-tower pipework with wet supports, flanges and low points.
COOLING-TOWER PIPELINES

WET SUPPORTS. FLANGES. LOW POINTS. REPAINTED AGAIN.

Red fire-hydrant ring main running through a plant.
FIRE-HYDRANT LINES

RUST NOW. FAILURE WHEN THE LINE MUST WORK.

Process pipework carrying acid and salt duty inside a plant building.
ACID + SALT PIPES

SALT AND ACID RESIDUE STAY ACTIVE INSIDE PITS.

A live refinery unit where blasting, grinding and hot work are prohibited.
LIVE HAZARDOUS LINES

NO BLASTING. NO GRINDING. NO HOT WORK.
THE RUST GETS A FUTURE.

An elevated pipe rack reached only by ladder and scaffolding.
ELEVATED PIPE RACKS

ONE HAND FOR WORK. ONE HAND FOR SAFETY.
REPAINTING MEANS SCAFFOLDING AGAIN.

SELECT THE PROTECTIVE SYSTEM BY PIPE EXPOSURE

DRY, WET, ACIDIC AND COASTAL PIPELINES REQUIRE DIFFERENT PROTECTIVE SYSTEMS.

PIPE EXPOSURE STANVAC SYSTEM CUSTOMER RESULT
DRY / DUSTY 2050 POLYHYB SHP Fast-drying, one-component direct-to-metal protection.

ENGINEERING CHECK

Z801: Approved local pits only after wall-thickness and fitness assessment. Z704: Remove loose scale, oil and contamination; wash salts first. Maximum 70°C. Confirm topcoat compatibility, layer order, film build and cure before application.

DO NOT OVERPAINT RUST.

THE PIT REMAINS. PIPELINE LEAKAGES ARE EXPENSIVE.

Z801 RESTORES LOST PROFILE. Z704 CONVERTS RESIDUAL RUST AND BUILDS THE TOPCOAT BOND.
