What is NFS 61?
NFS 61 is a standard that covers the design and manufacture of non–metallic flexible pipe systems for use in offshore oil and gas production applications. It specifies requirements for materials, design, manufacture, qualification, and testing, as well as installation and operation requirements. NFS 61 is intended to ensure that non–metallic flexible pipe systems are safe and reliable in offshore environments, and provides guidance on the selection and use of materials, welding, testing, and other aspects of non–metallic flexible pipe system design and manufacture.
