Hygienic & Environmental Engineering Services has bought two further Orbimatic orbital welding systems. The additional systems give HEES the ability to orbitally weld from 6mm diameter up to 115mm outside diameter pipe work. HEES invested in this equipment in order to meet the increasing QA/QC requirements of its clients. Hygienic & Environmental Engineering Services designs and installs high-purity pipework systems, including CIP and WFI systems.
