DAYU-X
About Us
DAYU-X supports product selection, protection-path review and application planning for industrial equipment affected by corrosion, heat, wear, erosion and heat loss.
About Us
Protection decisions start with the equipment and operating condition
Beijing Dayu New Materials Co., Ltd. focuses on functional coating systems for corrosion, elevated temperature, wear and thermal protection across industrial equipment and exposed structures.
A project direction is reviewed against the substrate, medium, temperature, exposure pattern, access and maintenance requirements rather than selected from one parameter alone.
Industrial problems
What we help industrial teams evaluate
Each route introduces the problem and the factors that influence a suitable protection direction.
Corrosion
Moisture, condensate and industrial atmosphere affecting metal or concrete surfaces.
High-temperature oxidation
Heat, thermal cycling and corrosive gas acting on hot equipment.
Acid, alkali and chemicals
Splash, immersion, mist or intermittent chemical exposure.
Wear and particle erosion
Material flow, impact and abrasion at transfer and gas-path surfaces.
Heat loss and insulation
Thermal management around equipment, vessels and pipework.
Solar heat gain
Outdoor roofs, tanks and structures exposed to solar radiation.
Combined conditions
Heat, corrosion, wear and access constraints occurring together.

Condition review
How we analyse an operating condition
A useful technical review starts with a clear description of the asset, exposure and existing damage.
The more complete the operating information, the more focused the initial product and system review can be.
- Industry and equipment type
- Substrate and existing surface
- Operating-temperature pattern
- Contact medium
- Location of corrosion or wear
- Continuous or intermittent duty
- Moisture, condensation, dust or salt
- Access and shutdown window
- Condition of any old coating
- Inspection and maintenance requirements
Working method
How a protection direction is formed
Understand the asset
Define the equipment, current problem and affected area.
Collect operating inputs
Organise substrate, medium, temperature and duty information.
Review the mechanism
Assess the likely source of damage or energy loss.
Set the objective
Clarify the protection, insulation or maintenance goal.
Match the system
Review suitable products and an application approach.
Plan follow-up
Include inspection, maintenance and local repair considerations.
Application control
Surface preparation and application matter
Material selection is one part of the result. Substrate condition, preparation, application control and curing must be reviewed together.
- Inspect the substrate before work
- Remove oil, dust, rust and loose material
- Review welds, edges and defects
- Check compatibility of existing layers
- Control the working environment
- Monitor each applied layer
- Follow product-specific curing requirements
- Inspect the completed surface and maintain it in service
DAYU-X
Quality-control focus
Project controls should remain traceable and appropriate to the confirmed product and work scope.
- Pre-work equipment inspection
- Surface-condition confirmation
- Material and tool preparation
- Detail treatment at edges and welds
- Application records
- Intercoat condition checks
- Final visual inspection
- Maintenance and local repair planning
