Huge Pressure Vessels for Mozambique

The Zungu-Elgin engineering team just completed two 2000m2 Roberts evaportors for Tongaat Hulett's Xinavane Mill in Mozambique within six months of receiving the order.

The vessels were designed by Tongaat Hulett Engineering Group, making them a proudly South African product.

The evaporators were built in five sub-sections so they could be transported by road to Mozambique where they will be assembled by Xinavane staff at the factory. The largest sub-section is the Calandria section which is 7.5m x 6m x 3.1m high and weighs in at 30.8 tons. When assembled, a complete vessel including tubes will be 12m high and weigh 99.5 tons. They have been supplied with vertical chevron entrainment separators makde from 3CR12 material for the 2nd and 3rd and 4th effect evaporators.

The vessels were built by a team comprising 12 coded welders and 5 boilermakers, supported by KIS 3rd party inspection services and technical support by Elgin's front end design office, managed by Francois Lombaard.

"Elgin Engineering was the ideal contractor for the job as we offer all disciplines under one roof. Even the 5.2m diameter dish ends were spun at Elgin. Our under roof cranes can handle heavy lifts up to 50 tons tandem, so we are able to work both day and night shift under roof and are not affected by weather. All sub-sections, including the Calandria, were manufactured in the workshop where they were also trial-fitted, shot blasted and primer painted by our Heat Seal Division prior to transportation," said Mr Vincent Chetty, Managing Director of Elgin.

Elgin has a long standing relationship with Tongaat Hulett, a global leader in the development of sugar processing equipment, and Elgin has direct access to their technology.
