1.0

INTRODUCTION This specification defines the requirements for titanium components complying with UNS R50400 for pressure systems manufactured in accordance with ASME B31.3, ASME B16.34, API 510, ASME VIII and PD5500. It is required to address deficiencies in the commonly utilised ASTM standards, which have been identified through practical field experience. The selected options in the referred standards and additional requirements shall be added or supersede the corresponding requirements in the referred standard. The latest revision of the specified design codes/ specifications at the time of contract award shall be used.

2.0

SUPPLIER QUALIFICATION Suppliers shall be able to demonstrate their ability to meet the minimum requirements of the applicable material specification and the additional requirements of this specification. Material suppliers, in addition to operating a BS EN ISO 9001 or equivalent accredited Quality Assurance system, shall:

3.0

•

Qualify to NORSOK M-650 Rev. 2 for titanium.

•

Display a knowledge and relevant experience in the type of material(s) to be manufactured. Experience may be demonstrated via statistical data or relevant test records for the types of materials to be supplied.

•

Maintain and operate acceptable facilities and equipment, which shall be calibrated at prescribed intervals. This should be undertaken in accordance with the supplier’s calibration procedure.

•

Be subject to a full audit by AMEC QA and Metallurgy unless the supplier can demonstrate an adequate system of control in the pre-qualification data submitted. However, if the criticality rating of the scope of supply dictates, a full system audit will be undertaken.

CERTIFICATION Unless specified otherwise in the item description or Purchase Order, certification is to be in accordance with BS EN 10204 Type 3.1.B with independent witness at the final mechanical testing stages. Specified certificates are to be supplied with the order.

4.0

PACKING & MARKING Packing is to be the responsibility of the supplier and shall be such as to ensure that the items are not damaged during transportation to AMEC. Particular attention should be paid to the adequate protection of bevelled ends and sealing faces using plastic caps. Items shall be palletised and shrink-wrapped. In addition further protection such as end protectors and wooden blocks shall be used. Titanium items shall be packed separately from all other items to avoid contamination. Titanium items (including pipe and plate) shall be packed utilising plastic banding and shrink-wrapping. Carbon steel banding shall not be used. In addition to the standard marking required by the relevant code and/ or standard each piece shall be marked with the item number. Where it is not possible to place this information on the individual piece, due to size, tagging or ‘bagging & tagging’ may be utilised. Any tags used must be securely attached and be of sufficient strength to minimise the risk of loss and/ or damage.

DOCUMENTATION Purchase orders may require the submittal of documentation for certain items or commodities over and above those documentation requirements stated in this specification. Should this be the case the documents required will be clearly stated in the Purchase Order.

GRADE DESIGN

Download And Print

Forged bodies, end adapters, extended bonnets or other flanged components shall be forged close to final shape. Forging shall have Cancel achieved at least 2/3 of the change in diameter in a flanged component, thereby limiting machining to 1/3 of the diameter change. ASTM B381 Grade F-2

Supplementary Requirement

None

Non-standard/ special piping components must comply with ASME B31.3 sect. 304. Manufacturers calculations demonstrating compliance with 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 to manufacture. Burst test data shall be m ade 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 µm 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 a detergent wash, followed by a thorough water rinse. Handling following cleaning should be minimized to avoid potential surface contamination.

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.

H ARDNESS 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 maximum design temperature exceeds 150°C.

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/ H IPed weight > 50kg.

TEST S AMPLING

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 with as 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 test samples. Additional test specimens shall be taken from the crotch region of tees for a second full set of tests. Sketches shall be established showing type, size and location of test specimens.

NON-DESTRUCTIVE TESTING

Final inspection shall take place after heat treatment, and final machining. Visual inspection Method: Extent: Acceptance criteria:

ASME V 100% of all surfaces MSS SP55 (No discolouration is acceptable)

Dye penetrant inspection Method: Extent: Acceptance criteria:

ASME V after final machining. 100% of all accessible surfaces. ASME VIII, Div. 1, Appendix 8.

Ultrasonic inspection Method: Extent: Acceptance criteria:

SURFACE TREATMENT

ASME V 3” and over & class 900lb or 65barg design pressure and above:

100% of entire pressure containing surface.

Shear Wave: cause

Any imperfection that produces a signal greater than the reference standard shall be for rejection.

Compression Wave:

Multiple indications with an amplitude exceeding 50% of the indication from a 3mm flat bottom hole, accompanied by a loss of back wall echo exceeding 50% shall be cause for rejection. 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 be able to detect surface embedded flaws of dimensions no greater than 50mm length by 3mm depth.

Annealed surfaces shall be supplied descaled.

DEFECT REPAIRS

Weld repairs are not acceptable.

M ARKING

The component shall be marked to ensure full traceability.
