product update | Materials and equipment OFFSHORE PVDF proves its durability
Solvay Specialty Polymers says its Solef 60512 PVDF can now boast 15 years of use in offshore oil and gas riser and flow line applications. No service failures have been reported since
Danish company NOV Flexibles first introduced the Solef resin in a flexible offshore pipe for the BANFF field in the North Sea in 1998, it claims. Solvay says more than 700km of flexible

riser, umbilical and pipe liners have since been produced using the Solef 60512 material, which was specifically developed for offshore applications. The polymer offers good mechani- cal performance, low permeability and good chemical resistance, including excellent resistance to sour gas. ❙

IKV foams with CO2
The Institute of Plastics Processing (IKV) at Aachen University in Germany, together with the Skilled Crafts unit at RWTH Aachen University, is developing a new foaming technology for production of foamed polyurethane using CO2
System 88 from Dhatec is a fully-adjustable pipe transport system designed to improve worker safety and minimise risk of damage to the pipes or coatings during shipping. The system, which comprises a series of zinc plated steel
profiles and moulded polyethylene support blocks, can be adjusted to safely support any pipe ranging from 8 to 80-inch diameter (219-2,032mm) using locking pins. According to Dhatec, System 88 can be used on trucks for
both road and rail movement and complies with Euronorm VDI 2700 requirements. ❙

COATINGS Dow targets performance FBEs
The Oudra Solution Series from Dow Coating Materials are high performance epoxy resins targeted at FBE coating formulations for the new generation of oil and gas pipelines, which operate at higher temperatures.
The range includes
OudraTherm HPC, which can be used to formulate FBE coatings with Tg values in excess of 160˚C. The product line also includes OudraCool HPC resin, which when formulated with
46 PIPELINE COATING | May 2013
Dow’s OudraCure HPC 90 hardener can be applied at temperatures as low as 170˚C. This minimises the risk of compromising the integrity of the steel pipe alloy, says Dow. ❙

blowing agent. The technique uses gas
counter-pressure in the mould at above the vapour
pressure of the dissolved CO2 to control the expansion of the foaming mix. Preliminary trials have yielded flexible foam parts with a density of around 90 kg/m³. ❙

in brief
❙ Russia’s Halopolymer says shims manufactured using its Fluoroplastics F-4 and F4-D have passed American Petroleum Institute 17J test requirements for explosive decompression resistance. The tests, carried out by MERL, showed that after 20 testing cycles involving pressure loading to 1,000bar at 130˚C followed by rapid decompression (less than one minute) the shims showed no defects, bubbles or ruptures.

❙ Clariant has introduced two new light stabilisers for use in waterborne coatings. Hostavin 3330 diso.XP and Hostavin 3070 disp.XP are non-migrating high molecu- lar weight HALS stabilisers for use in clear and pigment- ed systems. The 3030 dispersion is a triazine class UV absorber formulated with 52% absorber content and is claimed to provide high thermal stability. The 3070 grade is intended for use with the 3030 where enhanced performance is required.

❙ US-based Radiant Energy Systems has developed an infrared heater that com- bines infrared with air heating for use in dusty industrial environments. The SFA-Q Heater uses a stamped foil element with a front quartz plate, allowing infrared energy to pass through to the product while isolating the heater from the process and keeping it free of contaminants. ❙
