Unbonded Flexible Pipe

The NKT flexible pipe is an un-bonded structure consisting of helically wound metallic armour wires or

strips combined with concentric layers of polymers, textiles, fabric tapes and lubricants.

Each layer has a purpose:

Hydrostatic pressure: Carcass

Fluid barrier: Extruded polymer Liner

Inner pressure: Pressure Armour

Tensile forces: Tensile Armour

Corrosion: Extruded outer sheath

FAMILY 1

EXAMPLEFAMILY 3 EXAMPLE

GAS, OIL, WATER, CHEMICALS, SHALLOW/DEEP WATER ETC.

The main design is divided into three families:

Family 1 ”Smooth Bore” – smooth bore (liner), pressure + tensile armour, outer sheath

Family 2 ”Rough Bore” – carcass, liner, special tensile armour, outer sheath

Family 3 ”Rough Bore Reinforced” – carcass, liner, pressure + tensile armour, outer sheath

Each family may include special purpose layers such as anti wear and insulation layers.

End Fitting - From Flexible Pipe to Connector

Valve, Rigid Pipe, Flexible Pipe etc.

The end fitting is a mechanical device which forms the transition between the flexible pipe body and the

connector. The different pipe layers are terminated in the end fitting in such a way as to transfer the load

between the flexible pipe and the connector.

Common Flange Interfaces

API Standard

Most used and known flange system in NKTF end fittings. There are different types of flanges like 6A and 17D

SPO/NORSOK (Vector)

SPO are compact flanges (CFS). Tensioning of stud bolts deforms the flanges, which makes a good sealing. SPO’s have less diameter than other standard flanges with comparable loads

ASME / ANSI (shown as swivel type with rotating bolting interface)

A bit bigger than the API’s, but same dimension of gasket. Lower material grade can be used

SWIVEL RINGGrayloc

Grayloc is a clamp system that only requires 4 bolts. For easy installing

GRAYLOC CLAMP

Carcass Line

The carcass prevents collapse of the inner liner,

provides crushing resistance and mechanical

protection against pigging tools and abrasive

particles

An interlocking structure manufactured from a

metallic strip

Polymer inner liner and outer sheath

Outer Sheath is provided as a yellow UV-

stabilized Polyamide for dynamic applications or

Medium Density Polyethylene for static

applications.

NKT Flexibles’ proprietary extrusion technology.

Armouring Lines

•Armoring with C-shaped profiles or steel strips for

hoop reinforcement

•The pressure armour layers provide resistance to

radial loads

•Armouring with flat steel wires for longitudinal

reinforcement

•The tensile armour layers provide resistance to

axial tension loads

Flexible Pipe Families

Our present pipe size range is from 2.5 inches to

16 inches inner diameter. Design pressures are

from 15,000 psi for the smallest pipe bores to

4,000 psi for the largest.

Polymer Materials

XLPE (PEX)

The XLPE grade is the newest polymer

material that NKT can offer, and the

introduction of this material to the

market has been driven by the obvious

need for a qualified and more cost

efficient solution suitable for a wider

temperature range, bridging the low

temperature features of an HDPE liner

with the higher temperature capabilities

of a PVDF liner. NKT’s XLPE is

extremely tough and resistant, thus

making it an obvious alternative for PA-

11 and PVDF within its approved

design limits.

PVDF

NKT’s flexible pipe solution for high

temperature applications is to use an

unplasticized PVdF grade. The PVdF

grade is a co-polymer where the

individual PVdF molecules are

chemically bound to the molecules of

the plasticizing component.Typical maximum temperatures of polymer materials.

Design pressures are from 15,000 psi for the smallest pipe bores to 5,000 psi for the largest. NKT Flexibles is the industry leader in design and manufacture of flexible pipes for

high temperature applications with design temperatures as high as 130°C for both static and dynamic service.

The ONGC operated Mumbai High off Western Offshore consists of Mumbai High,

Neelam and Heera, Bassein and Vasai assets, situated 160km offshore Mumbai. It is

the largest oil field in India with 98 platforms and more than 1000 wells.

NKT Flexibles has previously supplied HHI with pipes for installation in Indonesia

and Korea. The MHB project represents the first cooperation between HHI and NKT

Flexibles in India.

The project comprises 8”ID Water Injection and Gas Injection flowlines

Project - Pipeline Replacement Project, India

PRP – Pipeline Replacement project for ONGC / L&T

This order covers the supply of flexible Water Injection flowlines in

relation to ONGC’s Redevelopment of Mumbai High North, South and

Heera fields.

The supply and installation period is stretched over 3 years:

• 13 pipe segments totaling 25.5 km to be installed in 1Q 2005

• 7 pipe segments totaling 18.8 km to be installed in 2006/07

• 7 pipe segments totaling 16.5 km to be installed in 2007/08

Since 1999 NKT has supplied more than 100 km of flexible flowlines to

ONGC for water injection, gas and sour oil production.

Summary

Thermal barrier layer build-up

The 3mm thick thermal barrier layer for the flowline structure consists of four layers of PP tape which will be wound around

the carcass in one process run. The layer build-up is shown schematically in Figure 2 including typical dimensions. The

winding process is controlled accurately thus ensuring a constant pitch along the pipe length. Furthermore, the

individual tape layers will be positioned in a way so that the gaps between adjacent tapes in a layer do not coincide with

gaps in the neighboring layer(s). Thereby, the thermal insulating property of the barrier layer will be uniform and any hot

spots are prevented.

A polyester tape (fabrication aid) will be wound around the thermal barrier layer to protect and secure the PP tapes before

extrusion of the inner liner.
