Turnkey field fabrication for critical industrial plants
We deploy mobile fabrication skids, qualified welding procedures (WPS/PQR) and dedicated site supervisors directly to your project location.
Storage Tank & Vessel Erection
Field assembly and full-penetration welding of API 650 & API 620 storage tanks, silos and hoppers.
Heavy Structural Steel Erection
Industrial trusses, pipe racks, equipment support structures and furnace superstructures.
Plant Process Piping
Carbon steel, alloy steel (P11, P22, P91) and stainless steel process piping to ASME B31.1 & B31.3.
Shutdown & Turnaround Teams
Rapid mobilisation of welding skids, orbital TIG machines and certified crews for planned turnarounds.
Why EPCs and plant owners choose Maple on site
Field fabrication needs safety discipline, qualified welding procedures and reliable mobilisation.
Zero LTI safety focus
Daily tool-box talks, gas testing and strict permit-to-work compliance on every site.
ASME & IBR qualified welders
Welders hold valid 6G/6GR qualifications under ASME Section IX and IBR with verified WQRs.
48-hour mobilisation
Mobile welding rigs, DG sets and rigging crews ready to move to site within 48 hours.
In-house WPS & PQR library
Qualified procedures across carbon steel, alloy pipe, stainless steel, Inconel and duplex.
Radiography-grade quality
High first-time radiography clearance across refinery, petrochemical and power piping joints.
Transparent pricing
Milestone billing and itemised per-MT rates with weekly man-hour reporting.
