Norimax management commitment to quality assurance is not matched by any other Thermal Spray specialist in this region. Our understanding of the extreme high standards and high quality assurance requirements for successful TSC applications is well recognized by the oil & gas operators in this region.

Norimax TSC management, TSC QA/QC team and TSC Sprayers commitment to high quality standards have been audited and approved by Shell Global Solutions International and is well recognized by other oil & gas operators.

TSC Standards and Qualifications

    • Norimax TSC team is committed to compliance with international standards such as ISO-14918 & ISO-14919, AWS C2.16, Norsok 501, etc.
    • Norimax TSC team is well-versed with company standards such as PETRONAS PTS 30.48.40.31, SHELL DEP 30.48.40.31 , EXXONMOBIL MPDS 29-02-07, etc.

Thermal Spray Coating

Thermal Spray is a process whereby metals, alloys and non-metals are melted by a heat source and are released through spray guns by compressed air.

Thermal Spray Coating (TSC)

i) Thermal Arc Spray
ii) Thermal Flame Spray

Thermal Flame Spray



Flame Spray Equipment Set-up

Fired by Oxygen and Acetylene


Thermal ARC Spray



Arc Spray Set-up

- 3 phase AC, 415 Volt,50 Hz,50 amps



Thermal Spray Coating

Arc Spray -
the most suitable for corrosion protection and the preferred method by Oil & Gas Industries - excellent adhesive and cohesive strength.

Why TSC is Specified

Require up to 30 years life expectancy in harsh environment.

Currently standard conventional Heavy duty coating systems- last only 3 to 5 years


Consumables

    • Aluminium
    • Zinc
    • Copper
    • Other Alloys

TSC Characteristics

    • Reduce Corrosion Allowance of Steel
    • Immediate Solidification submerge/commissioning
    • No Pot/Shelf Life
    • Inspection - Almost Instantly

THERMAL SPRAY COATING SYSTEM



Skilled & Qualified Thermal Spray Applicators



Surface Porosity

    • Porosity is inevitable in thermal spray coatings
    • Require sealer to seal the porosity
    • Sealer comply with service condition
    • Example: silicone-aluminium, epoxy, polyurethane sealers.

Sealer

    • Epoxy: to a maximum temperature of 120 °C
    • Silicone: to a maximum temperature of 450°C
    • Thickness ≤ 40 microns DFT
    • Low viscosity
    • No sealer required immersed or underground

Quality Assurance

-ISO 14918 Thermal Sprayer Pre-qualification tests:-

    • Dry Film Thickness
    • Adhesion Strength
    • Flexibility (Bend Test)

Areas for Thermal Spray Coatings

- Corrosion Protection

    • Splash Zone Areas – no maintenance required
    • High Temperature up to 600 °C
    • Cyclic Temperature
    • Corrosion Under Insulation – CUI
