Project Details

Denso were called in to assist in a project consisting of a series of dams, canals and pipelines situated in the Siphofaneni district of Swaziland called The Lower Usuthu Smallholder Irrigation Project (LUSIP). The purpose of the project was to supply water for irrigation to large sugar plantations and smaller local agricultural developments.

A section of the project consisted of 3500m of dual above-ground pipelines ranging from 2m to 1.1m diameter. The pipes were supplied by Hall Longmore with new age Sintercoat as the external protection to the barrels.

The engineers on the project were looking for long term corrosion protection of the welded field joints as well as a product which would bond to the Sintercoat on either side of the weld. The Denso Steelcoat 500™ System (Acrylic Pipeline Tape) was specified having a proven track record on various Sintercoated pipe bridges in South Africa. The pipeline contractor, Shearwater Construction, applied the Steelcoat 500 system to the field joints after being trained by the Denso team.
