Pipes concrete-coating

Technical capabilities of the plant:


1. Range of Pipes Diameters for Applying Concrete Coating - 10" - 40"
2. Concrete Coating Reinforcement - Galvanized Wire Mesh from 1 to 4 Layers
3. Thickness of Concrete Cover - Up to 210 mm
4. Obtainable Concrete Density For Concrete Weight Coating - Up to 3100 kg/m3
5. CWC Plant Capacity - 0,47 m3/min
6. Batching Plant Capacity - 0,6 m3/min

 

Technological Process of Concrete Coating Applying:


1. Feeding Pipe To The Racks For Anti-Corrosion Coating Control & Repair If Any
2. Installation Of Pipes On Transfer Cart And Application Of Concrete Coating
3. Pipes Weighing & Simultaneous Negative Buoyancy Calculation
4. Transportation To Storage Area
5. Damaged Concrete Coating Repair By Means Of Manual Gunite Machine
6. Installation Of Anode Protection

 

QA/QC plan:


1. Pipe and Raw Materials Receipt
2. CWC Coating Qualification (PQT)
3. Concrete Coating Production
4. Laboratory Productions Tests
5. Impact Test
6. Qualification of welding
7. Handling - Stacking of Coated Pipe
8. Records & Documentation

 

Organization of work:


1. Plant Fully Operational 12 Month Per Year
2. Ability to Perform Operations 24/7 (50 personnel per shift)
3. Particularly Developed Winter Period Procedure Allows High Quality Concrete Production In Temperatures till -10°ะก.
4. Storage Yard Area - 900 000 m2
5. CWC Plant Is Located In 700 meters Away From "Aladja" Port, Which Decreases The Time and Cost in Pipes & Materials Transferring
