Service Range
Crankshaft Refurbishment
Inspection, machining and dimensional-restoration services for crankshafts used in engines, compressors, pumps and other rotating mechanical equipment.
Depending on the component condition and approved repair scope, operations may include:
- preliminary visual inspection
- dimensional verification of journals and critical surfaces
- assessment of wear, scoring, ovality and taper
- checking of alignment and run-out
- cleaning and surface preparation
- grinding or precision machining of bearing journals
- polishing and surface finishing
- dimensional restoration within the specified repair limits
- inspection of oil passages and functional details
- final dimensional control
- preparation of inspection and repair records
The final repair method is selected following technical evaluation and confirmation that the component can be restored within the applicable dimensional and operational requirements.
Bearing and Bearing-Surface Refurbishment
Refurbishment of bearings, bearing shells, housings and associated support surfaces for industrial and mechanical equipment.
The service scope may include:
- inspection of bearing condition
- dimensional verification
- assessment of wear, scoring and surface defects
- checking of contact and seating surfaces
- restoration of bearing geometry
- machining or finishing of functional surfaces
- adjustment of clearances
- refurbishment of bearing housings and mounting interfaces
- replacement or restoration of associated components
- final fit and dimensional verification
Bearing refurbishment is performed according to the equipment design, operating loads, lubrication requirements, dimensional tolerances and approved repair specification.
On-Site Leak Remediation
On-site technical intervention for the assessment and remediation of leaks affecting industrial piping, flanged connections, equipment interfaces and process installations.
The intervention scope is determined according to:
- leak location and accessibility
- equipment or piping configuration
- operating pressure and temperature
- process medium
- condition of the affected joint or component
- shutdown availability
- applicable site-safety requirements
- approved repair method
Depending on the application, the service may include:
- leak-location assessment
- inspection of the affected connection
- evaluation of gasket, flange or sealing-system condition
- controlled tightening or adjustment, where technically appropriate
- replacement or restoration of sealing elements
- installation of project-specific repair components
- machining or correction of sealing interfaces
- post-intervention inspection
- preparation of intervention records
All on-site work is performed within the agreed technical and safety scope. The final remediation method must be approved according to the installation conditions and operational risks.
Electrolytic Zinc Plating
In-house electrolytic zinc-plating services for metallic components requiring corrosion protection, controlled surface coverage and a uniform technical finish. The process can be applied to suitable carbon-steel and ferrous components, subject to material compatibility, geometry and project requirements.
The treatment process may include:
- degreasing
- chemical or mechanical cleaning
- removal of oxidation and surface contaminants
- surface activation
- electrolytic zinc deposition
- rinsing and neutralization
- passivation, where specified
- controlled drying
- visual inspection
- coating-thickness verification, where contractually required
The final coating specification is established according to:
- component material
- geometry and dimensions
- exposure conditions
- corrosion-protection requirements
- coating-thickness specification
- surface appearance
- assembly and dimensional constraints
- customer or project requirements
Crankshaft and Bearing Refurbishment Parameters
- nominal and actual dimensions
- journal diameters
- ovality and taper
- concentricity and run-out
- surface roughness
- bearing clearances
- alignment of rotational axes
- condition of lubrication channels
- wear pattern
- material condition
- repair allowance
- final fit with mating components
No repair limit or dimensional tolerance is assumed unless it is defined in the original equipment documentation, customer drawing or approved repair specification.
On-Site Leak Assessment
- process medium
- operating pressure
- operating temperature
- flange or connection type
- gasket construction
- material compatibility
- accessibility
- installation condition
- shutdown or isolation possibilities
- site permit and safety requirements
Where the operating conditions do not allow a technically controlled and safe intervention, the affected system may require shutdown, isolation or removal before repair.
Surface-Treatment Parameters
- coating thickness
- substrate material
- component dimensions
- surface-preparation condition
- passivation type
- appearance requirements
- corrosion exposure
- dimensional limitations
- masking requirements
- threaded or fitted interfaces
- inspection and acceptance criteria
Critical fits, threads, sealing surfaces and other areas where coating build-up is restricted can be protected or masked according to the approved process specification.
Materials and Components
- carbon steel
- alloy steel
- cast iron, where technically suitable
- ferrous materials compatible with electrolytic zinc plating
- customer-specified materials approved following technical assessment
Material suitability is reviewed before repair or treatment. Certain materials, heat treatments, coatings or operating conditions may require additional technical evaluation.
