The representative section / length for coating and testing shall be mutually determined by the Applicator and Contractor, and should be similar material to the actual pipe or component being coated.

Alternatively, a minimum of 5 test coupons shall be fixed to a representative pipe section / length or component and receive the same surface preparation and thermal spray coating application as the actual workpiece. Three of the test coupons shall not be sealed, for the bend test, coating thickness, and adhesion measurements. The other two test coupons shall be sealed and sealer thickness and penetration evaluated.

A4.2.3 Companion Coupon

A companion coupon measuring (2.5cm to 5.0cm) x (10cm to 20cm) x 3mm with the same or similar chemical composition, heat treatment and properties as the work piece is used for this purpose. Bend test, pull-off adhesion, porosity and sealer penetration can all be evaluated on these coupons.

A4.3 Environmental Conditions

Refer to Section 2.0 of this Addenda specification.

A4.4 Surface Preparation

Refer to Appendix 4, COM-SU-2.02 Materials and Application of Painting and Protective Coatings.

A4.5 Coating Application

A4.5.1 General

The coating process shall comply with the manufacturing procedure established in the coating procedure qualification tests and the requirements specified in herein.

Vendor shall provide high capacity ventilation and extraction equipment. Vendor shall have completed an independent safety assessment by an expert familiar with the hazards of aluminium dust and explosion. Contractor shall complete a safety audit prior to commencing any work.

Thermal spray coating shall not be performed within 100mm of field butt weld locations. Suitable masking material shall be utilized on areas where thermal spray coating is not required. Contractor shall approve the locations and adequacy of masking prior to spray operations.



Revision: 0


Coating application shall be carried out within 4 hours of blasting.

A4.5.2 Preheating

Preheating is not required for arc spray application.

The item shall be heated to a temperature within the limits qualified by the Vendor during pre-qualification tests for the particular item, but in any event the surface temperature shall not be less than +10°C and 5°C above the dew point.

If the temperature moves outside the qualified limits the coating process shall stop until the fault is rectified.

Items exposed to temperatures outside the above limits shall be quarantined. Quarantined items shall not be used without approval of the Contractor.

During coating application, the steel surface temperature shall be monitored continuously by the Vendor. The means of temperature control, both at the heat source (if required) and point of application shall be proposed by the Vendor for approval by the Contractor.

Preheating requirements shall be validated with the bend test.

A4.5.3 Thermal Spraying

Crossing Passes

The specified coating thickness shall be applied in several crossing passes. The coating tensile bond strength is greater if the spray passes are kept thin. Laying down an excessively thick spray pass increases the internal stresses in the thermal spray coating and decreases the ultimate tensile bond strength of thermal spray coatings. The suitability of the crossing-pass thickness shall be confirmed with a bend test.

Manual Spraying

For manual spraying, right angle crossing passes shall be used to minimize thin spots in the coating.

Mechanised Spraying

For mechanized spraying (mechanized movement of the gun, workpiece, or both), overlapping shall be programmed to eliminate thin spots and stay within the coating thickness specification.

Rust Bloom

If rust bloom, blistering or a degraded coating appears at any time during the application of the thermal spray coating, the following procedure applies:

Stop spraying.

Mark off the acceptable sprayed area.

Re-prepare the unsatisfactory areas to the required degree of surface cleanliness and surface profile, including any areas where the thermal spray coating was applied to unsatisfactory surfaces.



Revision: 0


Feathering

The edges of the existing thermal spray coating shall be angle-blasted to provide a 5.0cm to 7.5cm feathered overlap of the new work into the existing thermal spray coating.

Thermal spray coating shall be applied to the newly prepared surfaces, and the existing thermal spray coating shall be overlapped to the extent of the feathered edge so that the overlap is a consistent thickness.

A4.5.4 Sealer Application

Sealers are intended to fill the porosity of the thermal spray coating and not to build film thickness. Typically, the sealer is applied at a spreading rate resulting in a theoretical 12μm dry film thickness. However, sealer shall be inspected at 30x power magnification to ensure that sealer can penetrate and fill up the interconnected pores. Pores at the surface may be tolerated. To facilitate sealer penetration into the pores, the sealer may be thinned with approved thinners and sprayed in two to three coats to meet the final coating thickness.

Prior to application of the sealing coat, the items shall be protected from weather.

Sealers shall be applied within 8 hours after thermal spraying.

If moisture is present or suspected in the thermal spray coating pores, the steel may be heated up to 65°C to remove moisture prior to the sealer application. Hot air blower shall be used to remove moisture, the steel shall be heated from the reverse side of the thermal spray coating to minimize oxidation and contamination of the thermal spray coating prior to sealing.

Sealer Spray Equipment

Spray equipment used to apply liquid sealers shall be equipped with dual air pressure regulation controls and pressure gauges for independent control of pot and gun pressures. Spray gun tips shall be in accordance with the coating manufacturer's recommendations for application of thin and low viscosity sealers.

The first coat of liquid sealer may be thinned with solvents to allow penetration into the pores of the TSA coating.

Thermal Spray Equipment Setup

Thermal-spray equipment (arc spray shall be used) shall be set up, calibrated, and operated according to the instructions and technical manuals of the manufacturer or thermal spray coating Applicator and shall meet the requirements of EN 1395.

Spray parameters and thickness of each crossing pass shall be set for spraying the specified thermal spray material and, at a minimum, be validated with the bend test.

The thermal-spray equipment‟s spray-parameter set-up shall be validated with the bend test at the beginning of each shift or crew change. The initial spraying for a few seconds shall be done on a test piece.

A4.6 Adhesion

During the thermal spray coating spray process, steel companion coupons shall also be used to assess the adhesion to the steel substrate by means of pull-off tests, according to ASTM C 633, or ASTM D 4541. All adhesion measurements shall be taken on unsealed thermal spray coating.

Measured adhesion values shall be corrected, as required, if curved test dolly surfaces are used.



Revision: 0


The minimum thermal spray coating adhesion strength shall be as specified in Table A4.1.

If the bond strength is less than the minimum specified value, the degraded thermal spray coating shall be removed and reapplied.

When the pull-off adhesion test is conducted on a production-coated component, the measurement shall be taken when the specified value is attained or the coating adhesion fails, whichever occurs first. Once the specified value is reached, the pressure from the tester shall be released, and the test dolly removed without damaging the thermal spray coating. Adhesion test areas shall be repaired if required, in accordance with Section A4.10. Measured adhesion values shall be corrected, as required, when curved test dolly surfaces are used.

4 Silicone sealer 2 10 20

Notes:

1 The first coating shall be diluted with solvent to assist in penetration into the pores.

2 Sealer applied only to fill porosity, not to build up a thickness of sealer material.

Coating thickness shall be determined in accordance with ASTM D1186.



Revision: 0


A4.8 Coating Appearance

The coating shall have consistent colour and shall be free from:

Blistering and other imperfections.

Entrained foreign matter.

The coating shall be blemish free, with no cracking, no dust or other particulate inclusions or other surface defects that would be detrimental to the integrity of the coating.

A "blemish" that has no detrimental affect may be acceptable if it meets the other criteria of being smooth, bonded and without the inclusion of foreign matter.

Sufficient „white‟ light (minimum 500 Lux) shall be used when performing the above visual inspections.

The metallographic examination of thermal spray coating cross-section of a companion coupon is used to measure porosity. The porosity shall not exceed 8% (volume). If the porosity exceeds the specified value, the work shall be rejected.

A4.9 Bend Test

The bend test entails bending a companion coupon through 180° on a 25mm diameter steel mandrel. Three companion coupons shall be abrasive blasted and sprayed as specified for the start-up of each shift, and every 250m2 for manual spraying, and every 500m2 for automated spraying. The bend test is passed if there is:

No cracking or spalling.

Thermal spray coating cracked but cannot be lifted from the substrate with a knife blade.

A4.10 Coating Repairs

Vendor may qualify a repair procedure for damage down to steel for Contractor review and approval. A maximum of one larger area of damage (40cm2 maximum) may be repaired. Damage outside these constraints or any areas showing cracking at edges shall require the whole item to be recoated.

Repairs shall provide a finished coating equal in effectiveness to that of the parent coating.

The number of coated items requiring coating repairs shall not exceed 5% of the total number of items coated.

Coating repairs exceeding 5% of the total number of items coated shall result in a deferment of coating activities until the cause of defects is identified and rectified to the Contractor‟s satisfaction.

A5.0 INSPECTION AND TESTING
