Stefmet Technologies are the sole agent for Res-Q pipe repair bandage.

Res-Q pipe repair bandage is a fast and simple way to temporarily repair damaged and leaking pipes. Res-Q pipe repair bandage can be used within the mining, marine, industrial and domestic sectors.

The pipe repair bandage is easy to apply and requires no specialized skills and cures with 30mins, ready for restart. The bandage is submersed in clean water for 10 seconds and then removed and wrapped around the pipe where needed.

  • Fast, effective in-situ pipe repairs
  • Real cost savings on plant maintenance downtime
  • No special tools required
  • No specialised skills required
  • High Chemical resistance
  • High pressure rating
  • Repairs to most pipe materials
  • Safe for drinking water lines

Gearbox Refurbishment

Stefmet technologies have in-house steel design and fabrication capabilities from small to medium engineering requirements. Stefmet Technologies can fabricateand line chutes,pipework,and launders,to deliver the excellent quality, service, and reliability that customers expect.


Stefmet Technologies refurbish all types of driveshafts in mining load haul applications. This is an often-overlooked part of the mine vehicle maintenance program that can yield huge savings for the mine.

Driveshafts can also be modified to include service free lube points for reduced downtime where access to these lube points is problematic.

Driveshafts are collected from the mine, refurbished to the highest quality and returned as new with the same OEM warranty. On request any vehicle that has a driveshaft can have it refurbished by Stefmet Technologies.

An inspection report is done on each driveshaft and submitted for evaluation before the repairs are done.

CrC Load Bin

Duramax CrC Wear Liner Plate is a product of Stefmet technologies in South Africa and is solely distributed through Stefmet Technologies
Full technical support will be available from both Stefmet Technologies as required.

Duramax CrC wear plate is ideal for the following applications where moderate to high impact and superior wear resistance is required:

• Dump Truck Load Bins
• Shovel faces
• Load Buckets

Stefmet Supply Technique:
• Submerged Arc Welding (SAW) Hard Facing with hardness of (HRC 58-65) depending on overlay thickness.
• Penetration typically 0.9mm – 1.7mm onto a high-grade mild steel base, resulting in a well bonded CrC overlay deposit to form the CrC overlay sheet.
• Fusion (welding) takes place under thick flux cover, eliminating oxide formation and gas pick-up.
• The process ensures an even and smooth surface using zig-zag weave beads motion with weld passes of approximately 25mm – 37mm in width.
• Surface cracking common on CrC is due to mismatch of coefficient of thermal expansion between 2 phases (base and overlay).
• CrC plate offers good strength, high hardness, and oxidation- & corrosion resistance at elevated temperatures ± 600°C.

• Cr: 27-37%; C: 3.5-5%; Mn:0.8-1.1%; Mo: 0.08-0.18%; Ni: 0.08-01.15% + additional micro filler elements (Typically Fe, etc.)
• Welding (Wear Surface / Overlay) – AWS: E FeCr-A1 Electrode
• Welding (Backing Plate / Fixing) – General Purpose Electrodes, i.e. E6013; E7018; MIG/C02
• Weldable thickness: 3mm – 40mm
• Specific Gravity (AVG) – 7,9
