Pipeline PU and Polyurea Protective Coating Solution
Plan a plural-component coating workflow for defined pipeline surfaces and operating exposure.
Build the Process Around Your Product
Plan a plural-component coating workflow for defined pipeline surfaces and operating exposure.
Product and material first
Start with the finished-product drawing, material system and acceptance requirements. The process route and equipment configuration are assessed together.
Capacity across the whole process
Define output with preparation, forming/reaction, curing, handling and inspection included. The slowest stage and product changes determine practical line capacity.
Haifeng scope centers on proportioning, heating, mixing and spraying. Blasting, pipe handling, extraction and inspection can be integrated against the project specification.
From Preparation to Qualified Product
A planning sequence for the specified route. Final settings and acceptance conditions are established through material and part review.
Define the coating duty
Separate internal lining from external protection and specify media, temperature and required coating performance.
Prepare the substrate
Agree cleaning, blasting/profile, repair and primer with the approved coating supplier.
Condition and proportion
Check component ratio, viscosity, heating and hose reach for the selected spray material.
Information Needed to Configure the Line
Provide these inputs so the equipment range, interfaces and validation plan can be defined.
| Design input | Information required |
|---|---|
| Pipe geometry | Diameter, length, internal/external surface and access |
| Coating specification | Material supplier, ratio, viscosity, film thickness and primer |
| Exposure | Temperature, transported media and external environment |
| Production arrangement | Shop or field, handling, ventilation, power and air |
Core Equipment and Integrated Interfaces
Haifeng scope centers on proportioning, heating, mixing and spraying. Blasting, pipe handling, extraction and inspection can be integrated against the project specification.
Coordinate the Equipment With the Process
Evaluate repeatability, handling and acceptance across the full workflow.
Material-specific configuration
Component circuits, thermal control, mixing and receiving equipment are matched to the approved chemistry and processing window.
Defined interfaces
Haifeng scope centers on proportioning, heating, mixing and spraying. Blasting, pipe handling, extraction and inspection can be integrated against the project specification.
Documented acceptance
The proposal defines trials, process records, inspection responsibilities and product-specific acceptance conditions.
