scope:

This specification provides requirements for the manufacture and qualification of layflat hose assemblies in onshore oilfield water transfer applications. Also included are performance requirements for materials, hose, and couplings.

These products consist of single or multiple layers of woven polymeric fibers lined with a polymeric material that is suitable for onshore oilfield water transfer service. The layflat hose assemblies addressed under this specification are capable of being spooled for storage, transport, and installation by both the original equipment manufacturer and the operator.

This specification is limited to hose and couplings and fittings and does not relate to other system components and appurtenances. Where other system components (e.g., elbows, tees, valves) are of conventional construction, they will be governed by other applicable codes and practices.

This document does not include products acceptable for use in sour services as defined by NACE MR0175/ISO 15156.
