We carry out blasting, underwater painting, and thickness inspection for maintenance inside large-diameter pipes to provide perfect protection!
After blasting a massive pipe weighing 2 tons and measuring 5 meters in length, we will perform underwater painting. A minimum film thickness of 300μm is required for the underwater painting. If the film thickness becomes too thick, there is a risk of peeling, so we will also pay attention to the upper limit of the maximum film thickness while painting. If the set values for the upper and lower limits are too close, the work becomes difficult. To meet these conditions, we repeated inspections and corrective painting multiple times. Ultimately, we achieved a final thickness within the range of 300μm to 600μm, resulting in a perfect finish.

basic information
【Rust Prevention Department】 Metals naturally rust in the atmosphere and in water, which not only detracts from the aesthetic appeal of products but also adversely affects the performance of the metal in various ways. In recent years, significant advancements in technology have led to the development of highly durable coatings. One essential process that is always performed as a surface treatment for these coatings is "shot blasting." No matter how durable the coating is, it cannot demonstrate its full potential without complete surface preparation, making shot blasting indispensable. Our "shot blasting" has been the focus of research and development in our Rust Prevention Department for many years. For all your needs in can manufacturing, blasting, and painting, please leave it to us. Harada Iron Works Co., Ltd. TEL: 082-232-2445 FAX: 082-293-0286 Email: bousei@harada-tekkou.co.jp

|---|---|
| Tank (In-house integrated construction) | [Product Information] Capacity: 30㎥ Weight: Approximately 4t. It has been coated with waterproof paint to hold water, ensuring both aesthetics and practicality by differentiating the interior and exterior surfaces. |
| In-house manufactured blast machine | The grid uses iron, and the sand is a non-metallic abrasive material. The grid is harder, resulting in greater surface roughness and shorter construction time, making it suitable for large fabricated products and paint stripping. Conversely, the sand is softer than the grid, resulting in less surface roughness and minimal deformation for thin materials. Additionally, since it uses non-metallic abrasives, it can be used even if the product is non-metallic. *For more details, please contact us. |
