Excellent and long term corrosion protection to ensure the durability of pipeline networks
Our purpose is efficient coating, uniformity and waste reduction
We are constantly improve our powder coating area to serve high-quality products to our customers.
Now the processes before and after coating are respectively:
- The semi-finished products which final controls are done transfer to coating area
- After deburring and grinding, surface preparation is done before coating
- Sandblasting is applied according to ISO 14901 with degree of SA 2.5 norm
- After sandblasting, corrosion begins in the product due to the humidity in the air. In order to avoid this undesirable situation, the material must be coated within 4 hours after sandblasting.
- Depending on the size and weight of the piece, we increase the heat up to 180C to maintain the 250 micron thickness
- We use two kinds of coating which are Electrostatic Powder and Thermoplastic
- To check the quality of coating, Holiday test and Pull-off tests are applied and thus the products become ready for packaging
We will continue to invest to achieve higher customer satisfaction.
