SGP Pipe Painting (Part 1) - Gasket Seat Protection and Blasting - After protecting and blasting the gasket seat, we will apply a thick film heat-resistant coating.
We will be installing SGP gas pipes of various sizes and diameters. When carrying out the installation, we will protect the gasket seat's serration processing area, as any scratches from blasting could compromise the sealing performance. Once the area is properly covered with cloth tape, we will proceed with surface treatment using blasting. After the blasting is completed, we will apply heat-resistant paint, but the "first part" will conclude with the blasting process. The heat-resistant painting and film thickness inspection will be introduced in the "second part," so please take a look. ◎ SGP (Carbon Steel Pipe for Piping) This is the most familiar steel pipe in our surroundings. It is generally referred to as SGP pipe, gas pipe, white pipe, or black pipe. (The white pipe is an SGP pipe that has undergone zinc plating.) It is used in many places such as buildings, homes, and factories. ◎ Serration Serration refers to a finishing surface with spiral or concentric thin grooves on the flange gasket surface. When flanges are joined together, the unevenness fits together, allowing for a secure connection.

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 must be carried out as a surface treatment for this coating is "shot blasting." No matter how durable the coating is, it cannot perform adequately without complete surface preparation, making shot blasting indispensable. Our company’s Rust Prevention Department has been engaged in research and development of this "shot blasting" for many years. For can manufacturing, blasting, and painting, please leave it to us.

| Tank (In-house integrated construction) | [Product Information] Capacity: 30㎥ Weight: Approximately 4t. It is coated with waterproof paint to hold water inside, ensuring both aesthetics and practicality by separating the interior and exterior surfaces. |
| In-house manufactured blast machine | The grid uses iron, and the sand uses non-metallic grinding materials. Since the grid is harder, the surface roughness is greater, which shortens the 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 grinding materials, it can be applied even if the product is non-metallic. *For more details, please contact us. |
