5 SURFACE PREPARATION AND CLEANING

5.1 Pipe with oil or grease shall be cleaned (prior to blasting) with solvent wash and/ordetergent wash and/or steam cleaning as required by our inspector. Spot removal of oil,grease and contaminates by use of solvents or detergents shall not leave a residue orcoating which adversely affects coating application and performance. Pipe with lacquermay not be run through the cleaning line unless all shot/grit is subsequently replaced with

virgin abrasive, and all rails and conveyors cleaned.5.2 Short joints may be tack welded before blasting or coating only when authorized by our

inspector. Pipe to tacked must be rebeveled to a position at least inch (6.4mm) backfrom the tack area. Rebeveling shall meet the requirements of 11.2.

5.3 Pipe shall be preheated following precleaning to a temperature in excess of the dew pointto completely remove all moisture. Pipe shall be preheated in a uniform manner to avoiddistortion. Abrasive blasting shall not be performed when the metal surface is less than 5degrees F above the atmospheric dew point or when the relative humidity of the air isgreater than 85% in the blasting area. The applicator shall measure the metal surfacetemperature, dew point, and relative humidity when warranted by the weather conditions orwhen deemed necessary by the inspector.

5.4 A centrifugal blasting machine shall be used with steel shot and/or grit. Specific abrasiveused is subject to testing and approval by the companys inspector.

5.5 Bevel lands and internal coating shall be protected from abrasive blast and impact damageat all times.

5.6 The surface to be coated shall cleaned to a Near-White finish in accordance with SSPCVis 1(SIS 05 59 00 Sa 21/2) or NACE No.2 Anchor pattern profile, as defined in SSPC Sp10, Appendix A.3, must be at least 1.5 mils (38 microns) and no more than 4.0 mils. (100microns).

5.7 The surface shall be inspected immediately after blasting and all slivers, scabs, andgouges made visible by cleaning shall be remove. Debris generated by grinding or filing

shall be removed by brushing, unless other cleaning arrangements are agreed upon withthe Company.

5.8 Any anchor pattern removed by excessive grinding shall be reblasted before coating.

Excessive grinding is defined as either.

a. Any conterminous ground area of more than 0.5 sq ft (0.05 sq m), or.

b. A total (cumulative) ground area of more than 2 sq ft (0.19 sq m) per 40 ft (12m)

length of pipe.

5.9 The company inspectors judgment will be final as to the surface condition required forsatisfactory coating. If, in the judgment of the Company Inspector, the surfaces are notcleaned suitably for coating, such pipe shall be recleaned.

5.10 Pipe once rejected shall not be coated until the Company Inspector has reexamined andapproved same for coating.

5.11 Pipe which has flash rusted or has not been coated within 4 hours after cleaning shall becompletely reblasted before processing.

5.12 All blasting abrasive shall be removed from the pipe interior prior to coating (see 8.7). Anymaterial thus removed shall be suitably collected to prevent contamination of the pipeexterior.

5.13 One (1) pipe joint per shift shall be checked with potassium ferricyanide indicating paper.At the discretion of the Inspector, the frequency of this check may be increased ordecreased. If a positive reaction with the indicating paper occurs, this shall be consideredproof of chemical contamination, and mandates phosphoric acid pretreatment of all pipethereafter. Such pretreatment shall consist of preheating the pipe to at least 120 degrees F(49C), followed by phosphoric acid solution wash, and a high pressure rinse with de-ionized water. The phosphoric acid concentration (% solution) shall be based on the levelof chloride contamination in accordance with manufactures specification.

5.14 Runners and conveyors between the abrasive blasting unit and the coating hood shall bewet cleaned daily unless more frequent cleanings is required by our representative.

6 QUALITY CONTROL, POWDER

6.1 The quality of all coating materials shall be controlled by the Applicator and monitored bythe Company.

6.2 When directed by the Companys Materials Quality Section, Applicator shall arrange forone-fourth pint (120 m) samples of each batch of coating material to be packaged andshipped to the Companys laboratory from the coating manufacturers plant on a weeklybasis, as the powder is manufactured.

6.3 The coating Applicator shall furnish clean, one-fourth pint (120 m) size, sealable containers(plastic bottles or metal cans) for the purpose of collecting powder samples as instructed

by the Companys representative.

The Applicator is to package and ship powder batch samples on a weekly basis to theCompanys laboratory. Each sample shall be indentified with the Purchase Order number,coating designation, and batch number.

The Companys laboratory shall monitor the quality of these materials. In the eventquestionable results are found it will be the companys prerogative to reject such batches.Batch samples should be sent well in advance of coating application to prevent laterrejection of pipe coated with such batches.

7.1.1 The use of reclaimed or reconditioned powder shall not be permitted unlessapproved by both the Company and the coating manufacturer.

7.1.2 The use of recycled powder (powder which is automatically and continuouslyrecycled from the coating hood back into the powder supply) shall be permitted only

when proper filtration equipment is installed. Such equipment shall include a filter of70 mesh or finer. This equipment shall meet the approval of the powdermanufacturer and the company Inspector. At no time shall there be more than 15%recycled powder mixed in with virgin powder.

7.1.3 Powder order than 6 months and 15 days shall not be used. Powder of lesser ageis rejectable if storage conditions are considered unacceptable by our Inspector.

7.1.4 If dry air is not circulated through fluidized beds while the plant is not operating, nomore than one-fifth of the normal load may remain in the bed. At the next start-up,only virgin powder may be added to make up a full load.

7.1.5 Fluidized bed magnets must be adequate to remove iron and steel contaminatesfrom virgin and recycled powder. These magnets are to be inspected and cleaned

at least twice per shift.

7.1.6 Any pipe heated to a temperature where there internal coating blisters or ashesshall become the property of the Applicator and under no circumstances shall bereconsidered for used by the Company.

7.1.7 Other pipe heated in excess of 525 F (274 C) (as determined by Tempil sticks orby the formation of a blue oxide on the steel surface) shall be rejected; the

Applicator shall have two alternatives:

a. Reimburse the Company for the total cost of the pipe or.

b. Pay the total cost of having yield strength, ultimate tensile strength, and fullcurve Charpy impact properties determined by both the Company and the pipe

manufacturer on each overheated joint of pipe. If results are acceptable to theCompany, the joint of pipe is acceptable; for recoating.

8 INSPECTION AND QUALITY CONTROL: PRODUCTIONCOATING

It is the responsibility of the Applicators Quality Control Inspector to advise the shiftforeman when conditions exist which adversely affect the external coating operation withrespect to cleaning, application or material performance, so that immediate correctivemeasures can be made.

The Applicator is responsible for meeting the following requirements for testing andacceptance of externally coated pipe.

8.1 Coating thickness checks shall be made with a film thickness gauge (e.gm Elektro-Physik Microtest or Positector) which has previously been calibrated using aNational Bureau of Standards non-magnetic coating standard with a thicknesswithin 20% of the specified coating thickness. Coating thickness shall bedetermined by the method described in SSPC-PA2, Section 2. A minimum of fivecoating thickness measurements shall be taken by the applicator on each length ofpipe. One of these measurements shall be a minimum of 5 ft [1.5 m] from the pipe

end.

8.2 Any length of pipe having less than the specified minimum average thickness orless than the absolute minimum thickness shall be completely recleaned to theoriginally specified surface, and recoated.

8.3 Maximum coating thickness is 10 mils [254 microns] above the specified minimum.

Pipe with coating of greater thickness is acceptable only at the discretion of ourInspector. Any additional testing required for acceptance of high mileage coatingshall be at the Applicators expense.

8.4 Holiday Detection

Jeeping (holiday detection) shall be done with a conductive rubber detector havinga crescent configuration that covers half the circumference plus at least a 2 in.[50mm] overlap on both sides of the pipe. Alternatively, a straight edged rubberdetector may be mounted parallel to the pipe, provided it is of sufficient length, so


36/47


PIPING

473400-PI-000-ESP-008

REV. D

27-05-2013

Pgina 11 de 22

that the entire surface area of the pipe is completely jeeped as the pipe rotates andadvances.

When and in-line jeeper detector is used, a minimum of 1.0 ft [0.30m] of each endshall be jeeped by hand, to ensure jeeping of the entire coated pipe surface,including that missed when an in-line jeeper is raised to clear couplings.

8.4.1 Jeeper shall contact all coated pipe surface, including the weld toe area. Any airgap between jeeper and coated pipe surface shall mandate rejeeping of the entirelength of pipe.

8.4.2 The detector shall be operated at a minimum of 1900 volts DC when the pipe

temperature is at or above 250 F [120 C] or at a minimum of 2000 volts DC whenthe pipe temperature is below 250 F [120 C]. Higher voltages (up to a maximumof 2400 volts DC) may be used at the Applicators option. Pulse-type jeep detectorsare also acceptable. The detector shall audibly detect and identify the location of aholiday.

8.4.3 The maximum allowable holiday density of any length of pipe of diameter equal toor greater than 10 3/4 in. [273 mm], is one per 25 sq ft [2.3 sq m].

For pipe of diameter less than 10 in. [273 mm], the maximum allowable holidayfrequency is one per 10 LF [per 3 m of length].

8.4.4 In the event that the maximum jeep count is repeatedly exceeded, the Applicatormay increase coating thickness at his expense, within the restrictions of 8.3.

8.5 Cured coating shall be of uniform color, gloss and thickness and shall be free ofblisters, pinholes, craters, fish eyes, sags, or other irregularities.

8.6 Complete cure of coating on each joint of pipe is subject to verification by theCompany prior to handling.

8.7 At our representatives discretion, any abrasive found inside pipe after coating iscause for plant shutdown and recleaning of the conveyors and power system.

8.8 Any pipe requiring closer inspection by the Companys representative shall be setaside for further inspection without additional cost to the Company.

Vendor shall perform the following destructive tests on one pipe from each lot of200 or fewer coated pipe of the same diameter and wall thickness. Failure of anytest constitutes rejection of all coating that was applied after the last test pipe withacceptable tests, and before the next test pipe with acceptable test. TheCompanys Inspector will select test pipe after coating and witness the tests. TheLocation of the samples to be tested at the cutback unless another location isauthorized by our inspector. See Appendix.

Ring samples cut from test pipe that is > 12 3/4 in. OD shall be approximately 12in. [300mm] long; ring samples from pipe 12 3/4 in. OD shall be approximately 18

in. [457mm] long. After samples are cut from the ring, the Applicator shall mark thedate of coating application on the unused portion of the ring sample. Testing of thesamples shall commence on the same day as coating application. Cutting andrebeveling shall be at the Applicators expense; pipe shall be at the Companysexpense, except where additional testing is required to clear a failed lot. Whenadditional test pipes are sampled to narrow the size of the failed lot, the cost of pipeand coating, which is cut-off for testing, and the cost of rebeveling the piperemnant. Shall be borne by the vendor. Additional test rings may be required by thecompany (up to 2 per turn); cost to pipe, coating,and cut-off for these shall be borneby the Company.

8.9.1 Bend tests shall be performed on duplicate longitudinal straps at 0 F [-18 C].

Either the mandrel method or the four-pointed bend method shall be used. Bendsshall be examined microscopically at 40X; any tear or crack in the coatingconstitutes a failure, unless located within [2.5mm] of the edge of the strap.

a. Mandrel bend tests shall be performed per API RP 5L7 par. 5.3.3.1 with anacceptance criterion of 2.5 /PD (deg/pipe diameter) total deflection at 0 F [-18 C].

b. Coating shall withstand an actual deflection (surface strain) of 1.5 /PD, asdetermined by measurement of strap curvature after bending. Such determinationshall not be made by de measurement of angle included between the strap

tangents (inclinometer method). Determination of the bend radius of the smoothbend area must be made, preferably by matching to drawn arcs of known radii (TGProcedure MQ-852).

8.9.2 A 4 in. [100 mm] square test panel shall be subject to a 48 hour, 3 volt cathodicdisbondment test at 150 F [66 C] (electrolyte temperature) using 3% salt solution.The test parameters (e.g. time, voltage and temperature) shall be checked andrecorded at least 5 times during the 48 hour test period (one check a test start and

end,and 3 checks in between).These checks shall be at least 6 hours apart but nomore than 16 hours apart. Any radial disbondment from the initial 1/8 [3mm] drilledhole less than or equal to 14mm constitutes a pass. Radii between 14 and 20 mmare subject to retest.

Other details of testing and acceptance shall be per API RP 5L7, par. 5.3.3.2,except that a 3 volt potential shall be used in lieu of 1.5 v, and acceptance limits of14 and 20 mm replace the API limits of 12 and 18 mm.

8.9.3 Coating chips shall be removed by bending a strap from each ring at lowtemperature, and examined with a 40X microscope. The coating chips are subjectto the following acceptance criteria.

8.9.3.1 Contamination (any material other than fusion bonded epoxy) on the underside ofcoating chips shall not exceed 40% of the surface area.

Steel fragments are included as contamination. A copper sulphate solution shall beused to highlight the steel dust contamination at the interface. The preferredmethod of a real determination is point counting, using an optical microscope of atleast 40X magnification, and a point count grid of at least 25 points.

8.9.3.2 Porosity shall not extend more than 60% of the coating thickness, excluding veryisolated pores. [i.e the outermost 40% of the coating thickness shall be essentiallyfree of porosity, excluding, isolated pores.] Alternatively, porosity distribution shall

have a void rating of 8 or less, as determined per Appendix 15 of API RP 5L7.

Under no circumstances will foam bond (cellular porosity) be tolerated. [Foambond is a condition resembling soap bubbles on the steel surface, where only thinmembranes of coating separate the pores. Generally, such a condition will permiteasy gouging and stripping of the coating with a simple knife test.]

8.10 The adhesion test shall be conducted per API 5L7 Appendix 9 with the acceptancelimit as specified in Section 3 of API 5L7. Alternatively, when specified by the

Company, the following adhesion test shall be conducted; the coating shall not stripor peel from the surface when a sharp knife is pushed through the fully curedcoating to the pipe surface and it is moved in a whittling motion along the pipesurface.

8.11 A hot water soak/moisture permeation test shall be conducted as specified in APIRP 5L7, Appendix 16 with the following modifications: (1) water temperature 175degrees F and (2) 24 hour immersion duration. The maximum rating shall be a 3.
