Hardfacing & Hardbanding
Overview & Service Scope
Ishar Oilfield Services' Hardfacing & Cladding Division provides specialised wear-resistant surface enhancement, tungsten carbide cladding, tool joint hardbanding, and NON Mag and Stainless steel welding UAE solutions for drilling stabilizers, fishing tools, NMDCs, and downhole equipment.
The primary objective of our hardfacing and hardbanding operations is to maximise abrasion and erosion resistance, eliminate casing and tool-joint wear, extend downhole run times, and reduce replacement costs in highly abrasive directional and horizontal drilling environments.
Equipment, Capabilities & Technical Specifications
Sizes, ratings, connection types, and operational specifications kept exactly as certified in technical documents:
1. Stabilizer Hardfacing (HF-1000 / HF-3000 / HF-5000)
Integral Blade, Sleeve, Near-Bit, String & Rotary Steerable StabilizersPrecision application of tungsten carbide tiles, inserts, and crushed carbide matrices onto carbon-steel and Non-Magnetic stabilizer blades.
- Equipment Covered: Integral Blade Stabilizers (IBS), Replaceable Sleeve Stabilizers, Near-Bit Stabilizers, String Stabilizers & Rotary Steerable Stabilizers
- Dressing Specifications: HF-1000, HF-3000, and HF-5000 tungsten carbide hardfacing
- Key Benefits: Increased blade life, reduced gauge loss, improved directional control, lower replacement costs & extended drilling run times
2. Fishing & Milling Tool Hardfacing
Crushed Tungsten Carbide Brazing & Wear-Resistant OverlaysHigh-density carbide dressing and refurbishment for fishing, milling, and downhole recovery tools.
- Overshots & Washover Shoes
- Spears & Taper Taps
- Junk Baskets & Fishing Magnets
- Milling Tools (Junk Mills, Pilot Mills, Watermelon & String Mills)
- Safety Joints & Rotary Cutting Shoes
3. Drill String Hardbanding Services (ARNCO / Castolin / Duraband)
Automated Casing-Friendly Hardbanding for Drill Pipe, HWDP & CollarsControlled application of industry-approved, crack-free hardbanding alloys onto tool joints and wear pads.
- Approved Materials: ARNCO, Castolin Eutectic, and Duraband hardbanding wires
- Components Covered: Drill Pipes, Tool Joints, Heavy Weight Drill Pipe (HWDP), Drill Collars, Subs & Crossovers
- Advantages: Superior protection from abrasive formation wear, reduced casing wear, lower maintenance costs & extended drill string longevity
4. PTA Carbide Cladding & Non-Mag / Stainless Steel Overlay

5. Complete Tool Refurbishment & Quality Certification
End-to-End Wear Assessment, Pre-Machining, Cladding, Grinding & NDTTurnkey restoration workflow bringing worn downhole tools back to full API gauge and OEM geometry.
- Step 1: Incoming wear assessment, dimensional gauging & LPI/MPI inspection
- Step 2: Precision pre-machining, old hardfacing removal & substrate rebuilding
- Step 3: Controlled pre-heat, qualified WPS hardfacing/cladding application & slow cooling
- Step 4: Precision OD cylindrical grinding to exact gauge tolerance
- Step 5: Final dimensional & LPI/MPI NDT inspection with full quality certification
