MANUFACTURINGPROCESS

Forging

SPECIFICREQUIREMENTS

Minimum reduction ratio 4:1

Forged bodies, end adapters, extended bonnets or other flanged components shall be forged close to final shape. Forging shall haveachieved at least 2/3 of the change in diameter in a flanged component, thereby limiting machining to 1/3 of the diameter change.

GRADE ASTM B381 Grade F-2 Supplementary Requirement None

DESIGN Non-standard/ special piping components must comply with ASME B31.3 sect. 304. Manufacturers calculations demonstrating compliancewith above requirements shall be made available free of charge to AMEC if requested.

Drawings for weldolets, flangeolets, nippolets, sweepolets and hubs must be submitted for review/ acceptance by AMEC prior tomanufacture.

Burst test data shall be made available for review where applicable (e.g. for flangeolets)

FINISHING Bevelled ends are to be bevelled in accordance with ANSI B16.25

Orifice flanges are to be supplied complete with Jack Screws.

Flange face finish shall be 3.2 - 6.4 m unless specified otherwise.

HEAT TREATMENT The components shall be annealed and air cooled. All parts should be cleaned carefully prior to heating using non-chlorinated solvents or adetergent wash, followed by a thorough water rinse. Handling following cleaning should be minimized to avoid potential surfacecontamination.

CHEMISTRY Chemical composition shall be determined by product analysis. At least two samples shall be tested to determine chemical composition.Samples shall be taken from the extremes of the product.

HARDNESS TESTING The hardness shall be less than 23 HRC (100HRB or 254 HV10).

TENSILE TESTING Elevated temperature tensile tests shall be carried out at maximum design temperature when wall thickness exceeds 30mm and maximumdesign temperature exceeds 150C.

IMPACT TESTING No impact testing is required.

EXTENT OF TESTING One set of tests shall be carried out for each heat and heat treatment load. A test lot shall not exceed 2000 kg for components with as

forged/ HIPed weight 50kg, and 5000kg for components with as forged/ HIPed weight > 50kg.

TEST SAMPLING Samples for production testing shall realistically reflect the properties in the actual components.

Test samples shall be from prolongations on actual component except for die-forged components and tees.

Sacrificial forgings shall be used for die forged components and for tees. Special agreements may be made for die forged components withas forged weight exceeding 50 kg. Integrated test blocks shall be used for HIP.

Test specimens shall be cut at the 1/4 T location from the surface near the weld preparation area, where T is the thickness of the testsamples. Additional test specimens shall be taken from the crotch region of tees for a second full set of tests. Sketches shall beestablished showing type, size and location of test specimens.

NON-DESTRUCTIVETESTING

Final inspection shall take place after heat treatment, and final machining.

Visual inspection

Method: ASME V

Extent: 100% of all surfaces

Acceptance criteria: MSS SP55 (No discolouration is acceptable)

Dye penetrant inspection

Method: ASME V after final machining.

Extent: 100% of all accessible surfaces.

Acceptance criteria: ASME VIII, Div. 1, Appendix 8.

Ultrasonic inspection

Method: ASME V

Extent: 3 and over & class 900lb or 65barg design pressure and above: 100% of enti re pressure contain ing surface.

Acceptance criteria: Shear Wave: Any imperfection that produces a signal greater than the reference standard shall because for rejection.

Compression Wave: Multiple indications with an amplitude exceeding 50% of the indication from a 3mm flatbottom hole, accompanied by a loss of back wall echo exceeding 50% shall be cause forrejection. Any indication with complete loss in back wall echo shall be cause for rejection.For thicknesses greater than 30mm the test procedure to be used shall be shown to beable to detect surface embedded flaws of dimensions no greater than 50mm length by3mm depth.

SURFACE TREATMENT Annealed surfaces shall be supplied descaled.

DEFECT REPAIRS Weld repairs are not acceptable.

MARKING The component shall be marked to ensure full traceability.

Supplementary Requirement None

FINISHING Bevelled ends are to be in accordance with ANSI B16.25.HEAT TREATMENT The components shall be annealed and air cooled. All parts should be cleaned carefully prior to heating using non-chlorinated solvents or

a detergent wash, followed by a thorough water rinse. Handling following cleaning should be minimised to avoid potential surfacecontamination.

CHEMISTRY Chemical composition shall be determined by product analysis. At least two samples shall be tested to determine chemical composition.Samples shall be taken from the extremes of the product.

WELDING Weld procedures for seam welds shall be qualified in accordance with UOG-ENG-SPC-45-001.


TENSILE TESTING Elevated temperature tensile tests shall be carried out at maximum design temperature when wall thickness exceeds 30mm andmaximum design temperature exceeds 150C.


EXTENT OF TESTING One set of tests shall be carried out for each heat and heat treatment load. A test lot shall not exceed 2000 kg.


Sacrificial fittings shall be used.

Test specimens shall be cut at the 1/4 T location from the surface where T is the thickness of the test samples as heat-treated. Sketches

shall be established showing type, size and location of test samples and extraction of test specimens.DIMENSIONALTOLERANCES

As per ASTM B363

In addition the difference between major and minor outside diameters, with one measurement taken at a weld location, shall not exceed5%. Excessive cold working or use of heat is not permitted.

The mechanical testing requiredfor the test bend will be subject to agreement between the supplier and AMEC. A drawing showing the location and orientation of allmechanical test pieces will be submitted to AMEC for approval prior to manufacture of the test bend.

If the results of mechanical testing from the test bend are considered acceptable then no further destructive testing of the productionbends will be required.
