Role Overview
You will supervise ALL stainless installation - TIG welded high purity systems AND Geberit Mappress press-fit stainless systems for utility services.
Role Description
Lead the stainless pipework crew delivering both welded (304L / 316L) and Mapress press-fit pipework across Boiler House, Turbine Hall, FGT, Water Treatment, WTP, compressed air, potable water, LTHW and chemical dosing support systems. Full control of quality, purge/weld quality AND Mapress joint integrity.
Key Responsibilities
- 1. Mapress Press-Fit - SpecialistMust be certified / competent in Geberit Mapress Stainless Steel system - Mapress SS304/316L, M-profileSupervise installation of Mapress 15mm - 108mm pipework - cutting, deburring, insertion depth marking, pressingControl pressing tools - Novopress / Geberit ACO203 / ECO301, ensure tools are calibrated, jaws are correct type (M15-M108), calibration certs in dateEnforce Mapress best practice - no carbon steel contamination, correct O-ring (FKM black / HNBR yellow), pipe end preparation, no distortion, support distances to Geberit specTrain and sign-off installers - only Mapress-approved operatives to pressManage leak testing of Mapress systems - air test 4.5 bar / hydro to 1.5x WP, ensure O-rings not displaced, conduct visual check of press indicatorMaintain Mapress material traceability - MTRs, Geberit genuine fittings, batch control
- 2. TIG / Orbital Stainless - GeneralSupervise TIG butt weld & orbital welding gangs for process pipework where Mapress is not suitable - dosing, demin, leachate, FGTEnsure WPS/PQR compliance, welders coded to EN 9606-1 / ASME IX, argon purge control with O2 ppm Client is pushing Mapress on all utility stainless to reduce hot works by 60%, speed up installation in ACC / Air Cooled Condenser area and admin buildings, and remove need for purge in occupied plant rooms. You must be able to defend Mapress vs welded decisions to QA.
