3 Terms, Definitions, and Abbreviations 3.1 Terms and Definitions For the purposes of this specification the following definitions apply. 3.1.1 backing steel The outer wall thickness pipe of a clad or lined pipe (for pipe clad on the outside and inside, the backing steel is the core material). NOTE Backing steel is sometimes referred to as base material or steel backing. 3.1.2 clad cladding Refers to a metallurgically bonded CRA layer produced by roll bonding, weld overlaying, powder metallurgy, or explosively cladding a carbon steel plate or pipe. 3.1.3 CRA layer A general term referring to any internal corrosion-resistant alloy layer. 3.1.4 lined Refers to a mechanically expanded, fitted or installed (“mechanical bond”) CRA layer with a carbon backing steel. 3.1.5 manufacturer As used throughout this specification refers to the firm, company, or corporation responsible for marking the product and warrants that the product conforms to the specification. NOTE The manufacturer may be either a pipe mill or a processor, as applicable. The manufacturer is responsible for compliance with all of the applicable provisions of the specification. 3.1.6 pipe mill A firm, company, or corporation that operates pipe-making facilities. 3.1.7 processor A firm, company, or corporation that operates facilities capable of heat treating pipe made by a pipe mill.
5.2 Description of Clad and Lined Steel Pipe Clad Pipe 5.2.1 Clad pipe is a bimetallic pipe composed of an internal (and in some cases external) CRA layer that is metallurgically bonded to the backing steel. The cladding may be bonded by hot rolling, coextrusion, weld overlay, explosion bonding, powder metallurgy, or some other process that produces a metallurgical bond. Clad pipe may be either seamless or welded as follows. a) Seamless. Seamless clad pipe is produced by the seamless process defined in API 5L (45th Ed.), Section 8.1 and shall meet the requirements of API 5L (45th Ed.), PSL 2. b) Welded. Welded clad pipe is produced from plate or skelp that has been clad by one of the processes described in 5.2.1. The backing material shall meet the requirements of API 5L (45th Ed.), PSL 2. The longitudinal seam of the backing steel shall be welded by one of the welding processes included in API 5L (45th Ed.), Section 8.1 except as follows. In addition, gas tungsten arc welding (GTAW) is acceptable for the tack welds, and plasma arc welding (plasma tungsten arc) [PAW (PTA)] is acceptable for the seam welds provided appropriate qualifications to API 5L (45th Ed.), Annex B are performed. For welding of the cladding material, processes in API 5LC (4th Ed.), Section 5.1 b) or resistance electroslag welding (RES) welding and PAW are permitted.
