In the past the service temperature for the external pipeline coatings has tended to be below 65 °C.  Both FBE (fusion bonded epoxy) and 3LPE (3 layer polyethylene) have performed reasonably well at these temperatures.  In recent years however higher service temperatures pipeline coatings ( >100ºC ) have been requested by the end users worldwide.   In response to this demand the coating manufacturers have fabricated several new high glass transition temperature FBE coatings for this market.  However as yet there is no publicly accepted test protocol to qualify these new coatings. A new test protocol to quality high temperature pipeline coatings will be presented and the preliminary data will also be demonstrated.  The test protocol includes the evaluation of the coating material thermal and thermo-oxidative stability and the resin-steel interfacial adhesion durability under the service environment. This test protocol has already been used to qualify the high service temperature pipeline coatings for major oil and gas operators including gas transfer lines with a design temperature of 110ºC.

Multi-layer polypropylene (MLPP) insulation coating is used for thermal insulation of subsea pipelines.  However in recent years - with higher wellhead operating temperatures - high temperature (HT) Fusion Bonded Epoxies have been used. This paper describes the author's experience with the MLPP systems over the last 20 years.

10002 Failure Analysis of Three Layer Polypropylene Pipeline Coatings

Product Number: 51300-10002-SG

Three layer polypropylene (3LPP) pipeline coatings failed prematurely in the oilfields of Abu Dhabi in the United Arab Emirates (UAE). A failure investigation and analysis into this phenomenon was instigated. The coating disbondment has been found to be due to high residual stress concentration and adhesion loss.
