What we do

Engineered off-site for fast field installation

Building inside our covered shop gives clean welding conditions, consistent heat treatment and pre-assembled modules that install faster on site.

ASME & IBR Pressure Vessels

Reactors, flash tanks, separators and air receivers with hydro testing up to 350 bar.

Process Skids & Modular Units

Pump skids, metering units, chemical injection skids and valve manifolds pre-assembled and tested.

Heavy Columns & Tubulars

Rolling and SAW welding of tubular piles, chimneys and distillation columns.

Corrosion-Resistant Overlay

Weld overlay cladding of Inconel 625, Monel and SS 316L for sour gas and petrochemical service.

Why Maple

Why engineers choose the Maple workshop

Plate rolling, sub-arc welding, heat treatment and hydro testing under one roof.

02

25T twin-hook EOT cranes

12-metre hook height for safe tandem lifting and loading of heavy modules.

03

50mm 4-roll plate bending

Cold rolling of heavy shells, cones and vessel rings up to 3,000mm width.

04

350-bar hydrotest bay

Pit testing with calibrated transmitters and charted pressure logging.

05

Blasting & paint booth

SA 2.5 abrasive blasting and enclosed epoxy painting in-house.

06

Full NDT & traceability
