EPCM was contacted by LeadEPC to perform hot tapping services on a plant cooling line within the Natref facility in Sasolburg, South Africa.
LeadEPC installed new equipment in the plant but needed to connect the main coolant lines to the new equipment. These lines are extremely critical to the operation of the Natref facility and can under no circumstances be interrupted without incurring major damages in loss of production at the refinery.
EPCM designed and fabricated complete split tees to accommodate the 4” coolant line. These split tees were manufactured according to the correct standard B31.3 and pressure tested before installation. The tees were installed by using the correct welding procedures and approved qualified welders.
Once the tees were installed EPCM pressure tested the equipment on the line and installed the new 4” ball valves.
Using hot tapping equipment EPCM successfully completed two 4” hot taps through the ball valves and retrieved the coupons.
The new equipment was connected and commissioned successfully. During the installation EPCM prevented any shutdown of plant services and had no safety or environmental incidents.
