Title Receiving Inspection

1. Pipe Receiving Inspection All pipes shall be visually examined for defect such as slag, arc strike, weld spatter, porosity, sharp edge, pit, lamination, slivers, crevice and internal ridges or welds that have not been properly scarfed.

Pipes containing these defects shall be segregated if the defects are to the extent they would reduce the coating quality.

If pipes are received from other pipe manufacturer the marking shall be recorded and kept for identification and the bevel end protector shall be kept and installed later after coating application has finished.

2. Coating Material Receiving Inspection

a. Receiving coating material shall be checked as per delivery sheet.

b. Check, verify and reported every batch of coating with the following items:

• Coating Manufacturer’s name address

• Product Type

• Batch No

• Quantity

• Certificate

• Date of Manufacture / expire date

• Packing Condition

c. Keep the coating material as per manufacturer specification.

Title Blasting, Primer & Coating Application

Blasting

Before blasting the pipe surface shall be cleaned to remove dirt or grease. All traces of oil and grease shall be brushed and wiped off using detergent/water cleaning (Aqueous solutions of household detergent) and a clean cloth. All moisture, if any shall be removed by heating using a gas burner or a hot air blower.

Weld spatter, scale, sliver, lamination and surface defect which are not remove during blasting shall be edges smoothed or rendered flush or removed by grinding and re-blast.

Any pipe which has been blasted but not primed and then wet by rain moisture shall be re-blasted. All moisture, if any shall be removed by heating using a gas burner or a hot air blower.

Every pipe is blasted to meet Sa 2 ½ standard by grit blasting, sand blasting or abrasive blasting.

Blasting shall not be commenced when humidity is greater than 85% or surface temperature shall not less 3°C above dew point, work in outside when it rain, any visible moisture is on the surface, the abrasive is wet, when painting is being done or coating is drying and curing in adjacent areas, and the lighting is poor and equipment is in improper working condition, at night.

The finishing surface of blasting shall be Sa 2 ½ or SSPC SP-10 It is compared to the pictorial standard. The roughness value shall be 30 - 80 microns as per ISO 8503-2. The roughness

profile depth shall be checked using a calibrated Elcometer roughness gauge or Keane-Tator profile comparator.

Coating Application

Epoxy coating which is applied shall be use High Build Epoxy Coating or as per PO.

Coating thickness as follows:

1st coat : minimum 50 microns with Zinc Rich Epoxy

2nd coat : minimum 200 microns with coal tar epoxy

3rd coat : minimum 200 microns with coal tar epoxy

Total coating thickness is 450 microns

The pipe surface temperature shall always be minimum of 3°C above dew point.

Section 8

Title Inspection and Repair Coating

Inspection Procedure

Report the ambient condition (Humidity, Dew Point) before and any change of weather condition during surface preparation.

Visual surface cleanliness shall be checked as per ISO 8501 and spot checks for dust level as per ISO 8502-3.

The surface preparation and surface profile shall be evaluate and reported at the beginning of each production shift.

DFT measurement shall be performed on every coat and reported.

DFT shall be checked as per SSPC-PA2 Standard.

Visual Inspection of finish every coat shall be performed and reported.

Specified Nominal Coating Thickness is 450 micron.

Adhesion test shall be conducted at first day application as per ASTM D4541

Repair of Coating

Degrease if necessary. Spot blast and clean the damage area back to with SA 2.5 and sweep blast the others if over

coating time has exceeded. Feather back the adjacent coating to minimum 20 mm and firm edge by sanding disc. Clean and apply at least 2 touch up coats with appropriate epoxy coating.

Section 9

Title Stock Yard

A. Pipe storage : The pipe shall be stored under which do not have any effect detrimentally to its performance characteristic.

1. Pipes with difference wall thickness shall be stacked at separate locations.

2. Storage area shall be well drained and free from any materials which may damage the pipe coating.

3. Pipes shall be stockpiled on a horizontal surface. They may be stockpiled in a pyramidal shape.

Soft dunnage or rubber shall be used to support the bottom layer and to eliminate contact of the coated pipe with any metallic surface.

4. The pipes shall be stacked with maximum 2 tiers during storage.

B. Handling : Pipe shall be handled in a manner to prevent damage to pipe walls beveled ends and coatings.

1. Padding shall be provided when loading for transfer to any location.

2. Pipes shall be raised or lowered to or from stock pile, ground, barge or truck by end hooks inserted in the ends of the pipe and carried by a wire rope with spreader bar between the lines.

As alternative for coated pipe, sufficient strength of nylon sling can also be used.

3. Pipes shall not be dropped

4. Pipes shall not be rolled on a surface that can damage the pipe.

5. Pipes shall be picked up clear of the ground on deck of the barge and moved bodily, and not dragged over the ground of the barge deck.
