Selected Highland Foundry Ltd Projects

LNG Pump Project

Highland was very pleased to be selected by a leading pump manufacturer in Japan to participate in a large liquefied natural gas (LNG) terminal project. Still under construction in 2007, the terminal will be located 17 km off of Italy’s North Adriatic coastline and when complete in 2008 will receive LNG, re-gasify the products and feed the gas through pipelines to the Italian gas distribution network. Up to 6 million metric tons of liquid natural gas will be transported to the terminal by the end of 2008.

Aker Kvaerner provided design, engineering and construction management for the owners Exxon Mobil/ Qatar Petroleum and Edison, an Italian company.

Highland, as an approved supplier of Duplex and Super Duplex Stainless Steel Castings to Exxon Mobil, provided the critical Vaporizer and Service Pump Castings. Patterns were constructed from supplied 3D engineered drawings and casting simulations were performed using SolidCast. Castings were dimensionally inspected, proof machined, tested and third party approved at Highland Foundry prior to shipping overseas.

The Casting Details

The material was Super Duplex, ASTM A890 Grade 6A.
Main components of the Vaporizer pumps consisted of:

Four- 2600lb Bowls
Four-1200lb Suction Bells
Four- 1150lb Impellers
Tests provided,
Chemical, Tensile, Charpy and Hardness Certification
Ferrite Determination- To ASTM E562 and Fischer Ferrite Scope
Corrosion Testing- To ASTM G48 Method A
Liquid Penetrant Examination- Per ASTM E165, Acceptance per ASME VIII
Metallographic Examination- Free of intermetallic phases and precipitates
Dimensional Inspection and Proof Machining

The same testing was performed on the Service pumps.
