Shot Blasting/Shot Peening Applications for Steel Shipbuilding:
1. Steel pre-treatment: It is the most fundamental and widely used application of shot blasting/shot peening in shipbuilding, typically carried out before steel is cut and welded.
2. Shot blasting/shot peening for ship hull blocks: After the steel has been fabricated into large hull blocks, secondary treatment is required.
3. Treatment and strengthening of welded joints: Welded joints are the weak points where hull structures are most prone to fatigue failure. Shot peening is an effective way to improve their fatigue strength.
4. Surface strengthening of critical ship components: In addition to the hull structure , many critical moving components on ships also require shot peening.
5. Shipbuilding, repair, and maintenance: Shot blasting serves as the primary method for removing old coatings and rust during the daily maintenance and dock repair of marine vessels.

We Understand Your Supply Requirements:
1. Compliance with International Standards and Shipbuilding-Specific Specifications: The shipbuilding industry is highly internationalized, and shot media suppliers must meet a range of stringent international and national standards, including requirements for surface preparation under Performance Standard for Protective Coatings (PSPC).
2. Strict technical requirements on the media: The industry sets demanding requirements on the media itself—chemical composition and metallographic structure, hardness range, particle size distribution, density, and defect control. Product performance directly affects the service life of marine corrosion protection systems and the safety of vessel operations.
3. Environmental and sustainability requirements: Environmental requirements in the shipbuilding industry are becoming increasingly stringent. Suppliers need to address abrasive recovery and recycling, dust and waste control, environmental policy development, and the growing demand for low-dust and eco-friendly media.
4. Comprehensive capability requirements for suppliers: Suppliers must meet comprehensive capability requirements, including stable mass supply capacity, full-process technical services, and standardized quality system certifications.

Tonglve metal's Solutions:
