Temporary protection solution for steel pipe

Acid pickling and zinc coating Loeco-Industrieanlagen, Germany, is involved in the engineering, manufacture and worldwide supply of industrial plants for the tube and pipe industry, with emphasis on environmental precautions and efficient automation for high-speed production and protective zinc-coating of top-quality tube and pipe. The company’s latest pipe pickling and galvanizing plant has started production at Tuper SA in Sao Bento do Sul, Brazil. This plant has been designed for round pipes from ½" to 6" diameter. To protect the environment and ensure workers’ health and safety, acid and zinc fume suction and cleaning are integrated into the plant, along with a flux preparation unit. The acid recovery plant constantly recycles the spent acid, for continuous high-quality pickling with no loss in production. Loeco has also modernised older pipe- galvanizing plants, by installing new handling systems on existing furnaces. The fully automatic pipe handling system has pipe dipping screws, pipe positioning and lifting devices, and a pipe extracting machine. The equipment can be designed to fit most existing galvanizing furnaces.

PPG Industries, Inc’s high-performance Raycron ® UV varnishes have been developed to protect steel pipes against red rust during storage and to minimise damage during overseas transportation. Raycron products are UV-cured clear coats made of 100% solids. The products are spray-applied directly onto brushed, untreated pipes, which can be packed immediately after curing. Designed to meet the specific requirements of steel pipes manufacturers, PPG’s Raycron Generation 2 varnishes have been developed to significantly improve rust protection. The pipes were tested by seven months of natural exposure in Dunkerque, 2m from the sea. The coated test pipes passed theASTM BS 117 salt spray test and demonstrated more than 200 hours rusting quotation ReO.

Raycron products also offer excellent scratch resistance and adhesion on brushed steel. Raycron coatings can provide advan- tages that go beyond the coated end product itself. Advantages include: • Good appearance and levelling • 100% solids coating; no water or solvent in the formulation • Line speed: up to 100m/min • Green technology • Short process • Immediate packaging after curing • TechnologyapprovedbyVenjakob (www. venjakob.de) for finishing equipment Raycron solvent-free coatings aid compliance with environmental regulations andcanassist productivitywitha faster curing process and higher transfer efficiency.

IHWT Radyne selected for Medgaz Project The international natural gas consortium Medgaz has completed the 210km under-sea gas pipeline due for start up during the second half of 2009. The pipeline will bring gas from Beni Saf on the Algerian Coast to Almeria in Spain.

The 24" diameter pipeline was laid in the shallower waters of the Almerian and Algerian coastline by the Saipem Castoro Sei, with Saipem 7000 laying the deeper sections at depths of up to 2.16km. IHWT Radyne supplied the induction heating equipment for both these successfully completed sections.

Saipem ENI purchased two Radyne containerised 450kW induction power modules and installed these on the Castoro Sei for the S-lay sections to preheat the 15,000 field joints prior to the application of shrink sleeves. IHWT Radyne containerised induction equipment was also used over the deep water J-lay section, heating and coating some 2,465 field joints on the Saipem 7000 using the proven Merlin 24 system.
