Compliance Standard:
SY/T 0315-2005
Application Fields:
Municipal, water supply, drainage, sewage, circulating water, chemical, power, and other pipeline applications.
Application Process:
Electrostatic spraying.
Precautions:
The steel pipe surface should be free of oil and moisture; the surface treatment quality should reach Sa2 1/2 level (GB/T 8923); the anchor pattern depth should be 50-90 mm; dust and abrasives on the steel pipe surface should be blown clean; preheating temperature should be controlled between 180-230°C.
The product should be stored in a well-ventilated, dry indoor environment with a temperature below 30°C, away from heat sources, corrosive chemicals, and chemical solvents, and protected from strong light exposure; the stacking height should not exceed four layers; avoid long-term pressure, ensure the packaging box is sealed to prevent caking and moisture, which can affect fluidization performance.
