Fabrication Facility

Aveng Grinaker-LTA's structural steel and pipe spool fabrication facilities are located in Vanderbijlpark, 60kms south of Johannesburg. These facilities are connected by road and rail to all major centres and have a monthly production capacity of 4 000 tons of structural steel and 35 000 diameter inches of welding. The pipe spool facility is currently being expanded to double its production and to provide for the training of welders. In addition to the 22 hectares on which the workshops are situated, Aveng Grinaker-LTA has a further
10 hectares dedicated to use as a laydown area, providing for the storage of client materials and completed pipe spools.

Projects

The most recent projects in which Aveng Grinaker-LTA has played a significant role, and demonstrated its multidisciplinary capabilities within the oil and gas sector, include an Octene plant that required the processing of some 8 000 isometrics totalling approximately 235 000 diameter inches of welding. An acrylic acid acrylates plant, with similar complexities, was also completed recently, as well as a polypropylene plant that included an input/output count of 10 500. During the two-year construction programme, Aveng Grinaker-LTA invested a total of four-and-a-half million manhours in the construction of this polypropylene plant - including the mechanical, piping, electrical and instrumentation requirements.
