ASTM F2805-11 - 1.8.2011
 
1. Scope

1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, markings for factory manufactured multilayer flexible steel pipe with thermoplastic inner and outer layers and end connections (Fig. 1). It covers nominal sizes 2 in. through 8 in. (50 mm through 200 mm). Flexible steel pipes are multilayered pipe products manufactured in long continuous lengths and reeled for storage, transport and installation. The multilayer thermoplastic and flexible steel pipe governed by this standard are intended for use for the transport of crude oil, natural gas, hazardous chemicals, industrial chemicals and water.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
