REFERENCE OBJECT

LONG CHIP SCREWS, 10 METERS

Crack detection and examination of the entire screw
Repair of damage in the core
Repair of stainless steel lining that has become loose and/ or worn down
Build-up and hard welding of outer diameter
Composite coating of the sides of the wings

Before we start the work, we always conduct a survey with measurement and evaluation of the damage. After the repair is completed, we measure the results in our quality control.

ROTOR CHIP FEED

Hard coating with very hard material on the outer diameter (dia = 780) and grinding to finished dimensions with very tight tolerances
Repair of other hard welds and building up of plates in pockets
PTA coating and machining of worn bearing seats on the pins

FEEDING SCREW CHIPS

Crack indication, examination and measurement
Replacement of one turn of the propeller wing and hard coating of this new part
Replacement of acid-resistant sheet metal around the core
Repair of the hard weld on the remaining part of the propeller wings

Before we start the work, we always conduct a survey with measurement and evaluation of the damage. After the repair is completed, we measure the results in our quality control.

ECCENTRIC SHAFT

Our surface coatings combined with a full mechanical workshop make us a unique emergency workshop. If you have equipment that rotates and/or is exposed to aggressive environments, Surftech can help you.

Here, an eccentric shaft has been completely renovated.

DOSING SCREW

• Direction of damaged wings
• Replacement of damaged sections of the wings and hard coating of the new outer surfaces
• Reinforcement of the wings where the material thickness approaches the minimum dimensions

• Ceramic composite coating of the feed zone where there is extra wear (gray coating)

• Repair of damaged hard surfaces
• Repair of damaged bearing and seal locations through PTA coating and machining

Before we start the work, we always conduct a survey with measurement and evaluation of the damage. After the repair is completed, we measure the results in our quality control.
