Section 5, par5.1

A. General

Inspections should be conducted in accordance with the inspection plan

Prior to performing an inspection, the inspector should be familiar with;

Thorough understanding of the inspection plan

Operating conditions since the last inspection (API 572 par 9.1)

Applicable damage mechanisms

Prior history

New inspection intervals shall be established if operating temp increases, operating pressure increases or process fluid changes. (API 510 par. 6.2.2)

Section 5

Interval is lesser of ½ remaining life or 10 years. If remaining life is LESS than 4 years, interval can be the full remaining life up to max of 2 years. (API 510 par 6.5.1.1).

SHALL be conducted by the inspector (API 510 par 5.5.2.1)

Primary reason for internal inspection is to find damage that cannot be found by external CML’s (API 510 par 5.5.2.1)

Internal inspection performed inside the vessel (API 510 par 5.5.2.1)

Internals may need to be removed to facilitate the internal inspection. Likely will not need to remove 100% of the internals. (API 510 par 5.5.2.2)

Inspector should consult with Corrosion Specialist to determine if it is necessary to remove any linings and/or deposits (API 510 par 5.5.2.3)

Vessels in non-continuous service, the interval is based on number of years of actual service, instead of calendar years, provided the vessel when idled is separated from process stream & not exposed to corrosive streams.

C. On-stream Inspection

Interval same as INTERNAL inspection.

Should be conducted by either an inspector or examiner. (API 510 par 5.5.3.1)

On-stream inspections performed by examiners shall be authorized/approved by the inspector (API 510 par 5.5.3.1)

Inside of vessel inspected from outside vessel. (API 510 par 5.5.3.2)

D. External Inspection

Performed by inspector or qualified others (qualified with appropriate training). (API 510 par 5.5.4.1.1)

Interval is lesser of 5 years or the internal interval.External inspections check; (API 510 par 5.5.4.1.2)

Condition of Outside surface of vesselCondition of Insulation systemCondition of Coating systemCondition of SupportsFor leaksHot spotsVibration damageAllowance for expansionBulging, misalignment, distortion, etc

Conditions discovered by others, must be reported to inspector. (API 510 par 5.5.4.1.3)

E. Thickness Inspection

Performed by inspector or examiner. (API 510 par 5.5.5.1)

No required interval.

Inspector should consult with corrosion-specialist when short term corrosion-rate changes significantly. (API 510 par 5.5.5.3)

Owner-user is responsible for assuring individuals taking thickness readings are trained and qualified (API 510 par 5.5.5.4)

F. CUI InspectionPerformed by inspector or other qualified personnel (i.e. same as external)Shall be considered for; (API 510 par 5.5.6.1)

Carbon steel and low alloy operating between 10oF and 350oF.Stainless steel operating between 140oF and 400oF.

Usually causes localized corrosion damage (API 510 par 5.5.6.2)Susceptible locations include; (API 510 par 5.5.6.2)

Insulation or stiffening ringsNozzles and manwaysStructural penetrations (ladder clips, pipe supports, etc)Damage insulationInsulation with failed caulkingTop and bottom heads

CUI inspection may require some or all insulation (API 510 par 5.5.6.3)Insulation may not need to be removed if; (API 510 par 5.5.6.3)

Insulation is in good condition and there is no reason to suspect damage behind the insulation;

CUI inspection can be performed with UT from ID of vessel.66

Weld Joint CATERGORY is the ”location” of a “joint” in a pressure vessel

Category A:All longitudinal welds in shell and nozzlesAll welds in heads, Hemi head to shell weld joint

Category B:All circumferential welds in shell and nozzlesHead to shell joint (other than Hemispherical.)

Category C and D are flange welds and nozzle attachment welds respectivelyLongitudinal welds (Category A) are more critical than Circumferential welds (Category B)because they are under double stress.This the reason why in different part of ASME code we have stringent rules in category Ajoint compared to category B joint.

When and where is there a code requirement for full radiography?

Item 1:

Item 2:

Item 3:

Item 4:

The point is this: items 1, 2 and 3 are similar, but item 4 is completely different. In items 1, 2 and 3 it is mandated bycode; to do full radiography in all butt welds in vessel so it means it is mandatory for designer to select column (a) inUW 12 table.

But in item 4, there is no mandating rule. A manufacturer with its own decision has chosen to use column (a) in tableUW 12 for full radiography.

All butt welds in vessels used to contain a lethal substance (UW 11(a)).Lethal substances have specificdefinitions in ASME Code in UW 2 and it is the responsibility of the end user to determine if they ordereda vessel that contains lethal substances.

All butt welds in vessels in which the nominal thickness exceeds specified values (UW 11(a). You can findthese values in subsection C, in UCS 57. For example, this value for P No.1 in UCS 57 is 1 ¼ inch. Nozzleslarger than 10 NPS or thickness greater than 1 1/8”.

All butt welds in an unfired steam boiler with design pressure > 50 psi (UW 11(a)).

All category A and D butt welds in vessel when “Full Radiography” optionally selected from table UW12(column (a) in this table is selected); and categories B and C which intersect Category A shall meet thespot radiography requirement (UW 11(a) (5) (b)).

a. Items 1, 2 and 3 from the previous slide; RT is related to the type of welds andservices.

b. Pressure vessels in these items are critical from a safety point of view, onecontains a lethal substance, the other one has a high thickness, whichimplicates high pressure, and the last one is an unfired steam boiler

c. Item 4 has no criticality like the other items have.d. But you should note all 4 items have been categorized in full radiography

clause( U 11(a)), so to differentiate item 1, 2 and 3 from item 4, the RTsymbols are used in Code (UG 116).

RT 1: Items 1, 2 and 3, (E=1), All butt welds full length radiography

RT 2: Item 4 (E=1), Category A and D butt welds full length radiographyand category B and C butt welds spot Radiography

RT 3: (E=0.85), Spot radiography butt welds

RT 4: (E=0.7), Partial / No radiography

You need to consider the hemispherical head joint to shell as category A, but ellipsoidaland torispherical head joint to shell as category B;

Do you know why? Why ASME considered the stringent rule for pressure vessel RT test inhemispherical head joint?

It is because this joint is more critical, because the thickness obtained from theformula for hemispherical head approximately would be half of the shell thickness;It means if the shell thickness is 1 inch, the hemispherical head thickness would be0.5 inch.

WPQ Welding Variables

WPQ Welding VariablesReference WPQ MR. ROD BURNER to answer the following questions;

Welding Procedure - Requirements (WPS)

1. WPS requirements (QW-200.1, page 14)

a. WPS provides directions for making production welds.b. Must contain essential, nonessential and when required

supplementary variables.1) Must reference the supporting PQR

c. Changes can be made to “nonessential” variables withoutrequalification. Changes to “essential or supplementary” variablesrequire requalification.

d. Format of WPS may be any format as long as every essential,nonessential and supplementary variable is included.

e. WPS must be readily available at the fabrication site for review bywelder and inspector.

Welding Procedure – Requirements (PQR)

a. Is a Record of the welding data used to make the test coupon andmechanical test results.

a. Must;1) Contain essential and supplementary variables (supplemental is not API 570 Exam).2) Record range of variables used to make the coupon must be included3) Be certified by the manufacturer/contractor (i.e. signed and dated).

b. Changes to the PQR are not allowed, except for editorial type changes (i.e. P# enteredincorrectly, or Code changes the F# for the materials used, etc.) All changes to a PQR,require recertification (i.e. signed and dated by manufacturer/contractor).

c. Format may be any format as long following are included;a. Essential and supplementary variablesb. Type of mechanical test, number of tests and test results

d. PQR must be available for the AI, but not the welder.e. There could be multiple PQR’s supporting one WPS or multiple WPS’s for a single PQR.

1. WPS is prepared for production welds that are to be made.

2. Welder (employee or contracted out), makes a Test Coupon using directions fromthe WPS.

3. The coupon is mechanically tested - Bends and Tension test (RT is not allowed).

4. If mechanical testing is acceptable, WPS is Qualified within ranges set by variablesused to make the test coupon.

5. PQR is a record created based on variables used to make the test coupon andsubsequent mechanical testing results.

NOTE: PQR “Must” be signed and dated to be CERTIFIED.

(QW-201)

(QW-100)

(QW-202.2)

1. What is the difference between the Procedure QUALIFICATION andWelder QUALIFICATION?

A. Procedure qualification requires TWO documents (WPS/PQR).

B. Examinations are different;

C. WPQ only requires “Essential” variables to be recorded,while the WPS must record “Essential, Non-Essential and Supplementary(when required) variables”.PQR must record “Essential and Supplementary” variables.

WPS/PQR – requires Bends/Tension test and Charpy test when notchtoughness is required. Also, Hardness when PWHT’d.

WPQ – requires VT and Bend test or RT/UT examination.2)

1. Verify WPS has been properly completed and addresses requirementsof Section IX (for API Exam, means Essential Variables and Non-Essential variables areaddressed) API 577 par 6.4 page 18

2. Verify PQR has been properly completed and addresses requirementsof Section IX (for API Exam, means Essential Variables are addressed and PQR is signed anddated) API 577 par 6.4 page 18

3. Verify PQR essential variables properly support the range specified inWPS (for API Exam, means Essential Variables are addressed and PQR is signed and dated) API 577

par 6.4 page 18

INSTRUCTIONS for Checking WPS and PQR

STEP 1 Locate the appropriate “Welding Variables Chart” for the Welding PROCESS (i.e. SMAW– QW 253, SAW-QW 254 or GTAW -QW 256……these are the only three that will be on the API Exam).

STEP 2 Verify PQR is signed by Manufacture/Contractor – QW202(b).

STEP 3 Verify WPS references the supporting PQR – QW201(b).

STEP 4 Verify all Non-Essential variables are addressed on the WPS, and validate that on the checklist (e.g. enter “OK” or “ERROR” inthe VALIDATE column) - QW201(b).

STEP 5 List values for all “ESSENTIAL” variables on Checklist from the PQR – QW202(b).

STEP 6 List values for all “ESSENTIAL” variables on Checklist from the WPS – QW201(b).

STEP 7 Use Section IX to determine and list the “ACCEPTABLE” range for all essential variables (based on the PQR results)

STEP 8 Compare the “Acceptable” range against the WPS values and document the findings in the “VALIDATE” column.

STEP 9 Check TESTING data on PQR and verify correct type/number of BEND specimens (i.e. 2 face & 2 Root, etc) were tested andresults are acceptable or rejectable. Record answer in “Validate” column of checklist.

STEP 10 Check TESTING data on PQR and verify correct type/number of TENSILE specimens (i.e. 2 or more, depending on thickness)were tested and results are acceptable or rejectable. Record answer in “Validate” column of checklist.

STEP 11 Check for P-No and/or F-No mistakes.

Practice Question for Reviewing WPS/PQR

Par UCS-56(c.)Heating rate above 800oF shall not be more than 400oF per hr/max metal thickness. Par UCS-56(d)(1)(2).Variation in temperature cannot exceed 250oF in any 15 ft length of vessel. Par UCS-56(d)(2)Holding time is per Table UCS-56During holding time, temperature cannot vary by more than 150oF. Par UCS-56(d)(3).Cool down rate shall not be more than 500oF per hr/max metal thickness. No control necessary below 800oF. Par UCS-56(d)(5).

A 2” thick vessel fabricated from SA-516-70N was repaired and PWHT’d at 1000o F. How long should the vessel be maintained at this PWHT temperature?

ANSWER 4 hrs & 15 min

A 3” thick vessel fabricated from SA-516-70 was repaired and PWHT’d at 950o F. How long should the vessel be maintained at this PWHT temperature?

Post Weld Heat Treatment (PWHT)( API 510)

API 510PWHT should be made as required by ASME Code (Par 8.1.6.4)Local PWHT may be substituted for 360 degree banding on local repairs (Par8.1.6.4.1)

If approved by the engineer.A preheat of 300oF or higher is maintained during weldingPWHT temperature maintained for a distance not less than 2 x t, from the toe of the weld.At least two thermocouples must be used.Metallurgist approves the PWHT procedure if it is performed for environmental assistedcracking resistance.

If a repair is made to a vessel after PWHT. A Minimum preheat of 200oF shall bemaintained during the repair for P1 materials. And 350oF for P3 materials. Par UCS-56(f)(4)(b).

No welding recommended at temperatures lower than 0oF. Temperatures between 32oFand 0oF, surfaces within 3” of the weld should be heated to a minimum of 60oF. Par.UW-30.

PWHT can be avoided for certain thickness. Example: P1 between 1 ¼” & 1 ½” doesn’trequired PWHT if a minimum of a 200oF preheat is applied during welding.

Preheat in lieu of PWHT for P1 and P3 materials, provided;1. Preheat temperature maintained at a minimum of 300oF.2. Preheat temperature maintained at a distance of 4” or 4t, whichever is

greater, on each side of weld3. Maximum interpass temperature of 600oF
