In 2011, Pneumofore engineers travelled to India for the commissioning of six vacuum systems model UV16 H B2500B, delivered to Narmada Offshore Constructions, specialist in pigging and hydro-testing to serve the oil, gas and petrochemical industry. The pipeline is in Ujjain, near Indore and measures 48 inch [DN 1200] diameter for the length of 90 km.
The vacuum drying method was applied after the dewatering with pigs. The considerable volume of 102.000 m3 was evacuated down to 0,3 mbar(a), which corresponds to the Dew Point of -32°C in 6 days only.
Mr. Selva Kumar, Project Engineer of Narmada, stated: “Thanks for your company having such a product like UV16, this is really a perfect product for our pipeline drying operation. We have successfully completed 48” x 90 kilometers pipeline vacuum drying within 6 days without any major problem.”
