3.2.3 fining. n — a component for non-bolted joints in piping systems.
3.2.4 flonçe, n — a component for bolted joints used in piping systems.
3.2.5 forging. n — the product of a sub4antiaIly cornpressive hot or cold plastic working operation that consolidates the material and produces the required shape.
3.2.5.1 Discussion — The plastic working must be performed by a forging machine, such as a hummer, press. or ring rolling machine, and must deform the material to produce a wrought structure throughout the material cross section.
3.2.6 seamles.c tubing, n — a tubular product made without a welded seam.
3.2.6.1 Discussion — It is manufactured usually by hot working the material, and if necessary, by subsequently cold finishing the hot worked tubular product to produce the dcsircd shape. dimensions and properties.
4. Ordering Information
4.1 It is the purchaser’s responsibility to specify in the purchase order all ordering information necessary to purchase the needed material. Examples of such information include, but are not limited to. the following:
4.1.1 Quantity.
4.1.2 Size and pressure class or dimensions. (tolerances and surface fInishes should be included),
4.1.3 Specification number with grade or class, or both, as applicable, and year/date.
4.1.4 Supplementary requirements, and
4.1.5 Additional requirements.
5. Melting Process
5.1 Unless otherwise specified in the individual Product Specification, the steel shall be fully killed,
5.2 II a specific type of melting is required by the purchaser. ii shall be stated on the purchase order.
5.3 The primary melting may incorporate separate degassing or refining and may be followed by secondary melting, such as electroslag rernelting or vacuum remelting. If secondary melting is employed, the heat shall be defined as all of the ingo remelted from a single pri— mary heat.
5.4 Steel may be cast in ingots or may be strand cast. Vhen steel of diII&nt grades is sequentially strand cast, identification of the resultant transition material is required. The steel producer shall remove the transition material
16.1.3 After repair welding, the welded area shall be ground smooth to the original contour and shall be completely free of dekcts as verified by magnetic particle or liquid penetrant inspection, as applicable.
16.1.4 Repair by welding shall not exceed lOf of the surface area of the part. or 33 of the wall thickness of the finished product, or in. 110 mml deep at the location of the repair.
16.2 The weld repair shall conform to 9.2 and to the additional requirements, if any. invoked in the Product Specification.
17. Inspection
17.1 The supplier shall afford the purchaser’s inspector all reasonable facilities necessary to satisfy him that the material is being produced and furnished in accordance with the general specification and the applicable product specification. Site inspection by the purchaser shall not interfere unnecessarily with the supplier’s operations.
18. RejectIon and Rehearing
18.1 Samples representing material rejected by the purchaser shall he preserved until disposition of the claim has been agreed upon between the manufacturer and the purchaser.
18.2 Material that shows injurious defects subsequent to its acceptance at the manufacturer’s works will he rejected. and the manufacturer shall be notified.
19. Certification
19.1 Marking of the specification number and manufacturer’s name or trademark on the parts, and printing of the same on test reports, shall be certification that the parts have been furnished in accordance with the requirements of the specification.
19.2 Test reports shall be traceable to the heat identification on the parts. They shall contain the information specified by the Product Specification and the purchaser order. They shall include the specification number and year/date of issue.
19.3 A ccrtificatc printed from or used in electronic data interchange (EDI) transmission shall be regarded as having the same validity as a counterpoint printed in the certifiers lacility. The content of the EDI transmitted docunient shall conform to any existing liDI agreement between the purchaser and supplier.
