API SPEC 2B
Specification for the Fabrication of Structural Steel Pipe
|Publication Date:||1 May 1996|
1.1 This specification covers the fabrication of structural steel pipe formed from plate steel with longitudinal and circumferential butt-welded seams, typically in sizes 14 inch outside diameter (OD) and larger with wall thickness 3/8 inch and greater (up to a nominal 40 feet in length) suitable for use in construction of welded offshore structures. The use of the ERW process or spiral welded pipe is not included in this specification. Pipe fabricated under this specification is intended to be used primarily in piling and main structural members, including tubular truss connections, where internal stiffeners are not usually required.
1.2 Manufacturers desiring to apply the API Monogram to the products covered by this specification shall demonstrate to the satisfaction of the American Petroleum Institute a program of education, training, experience, and/or examination assuring the manufacturer's personnel are competent in welding, inspection, nondestructive examination, and testing required or referenced by this specification.
