Test results confirm the improved temperature performance and remarkable durability of Hyperlast Syntactic Deep Water flowline insulation.

Hyperlast Limited’s Glass Syntactic polyurethane developed for the insulation and protection of deepwater flowlines has just passed its latest and most rigorous test. Increasingly, Hyperlast ‘Syntactic DW- 512’® coating, which performs at depths of up to 3,000m, is the industry’s preferred oil pipeline insulation and protection system. ‘Hyperlast Syntactic’ has been coated on to over 700 kilometres of pipelines and in excess of 35,000 field joints in the world’s principal oil producing regions.

This very demanding evaluation is the culmination of a 12-month procedure designed to measure the thermal insulation properties of Hyperlast DW512/150 and DW512/300 flowline coating products.

In simulated conditions, a section of coated flowline was subjected to the attritional effects of the environment in which the pipe has to perform: sustaining constantly high internal pipe temperatures in seawater for a very prolonged period provided a rigorous test for the coating, verifying its high insulation and bonding properties as well as the degree to which water absorption had taken place. The effects of plasticisation of the coating at the water surface and degradation at the pipe surface were measured, as were tensile strength and elongation and material properties at different depths from the water surface. The test pipe, which showed little overall sign of deterioration after the twelve months on test, was repaired after testing and reserved for re-evaluation at a future date.
