Core Product Introduction
1. Watertight door handle
Function: Designed for ship watertight doors to ensure rapid opening and closing in emergencies and ensure cabin watertightness.
High strength: tensile strength ≥520MPa, impact resistance, and deformation resistance.
Corrosion resistance: 316L material, passed 300 hours of salt spray test, suitable for a high salt spray marine environment.
Humanized design: ergonomic, non-slip surface treatment, easy to operate with gloves.
Use: Suitable for ship watertight doors, fire doors, escape passage doors, etc.

2. Special-shaped flange valve body
Function: Used in ship piping systems to control fluid delivery and ensure sealing and pressure resistance.
Precision casting: one-piece molding, no welds, avoid leakage risks, pressure bearing capacity ≥PN40 (4.0MPa).
Corrosion resistance: 316L ultra-low carbon stainless steel, resistant to seawater and acid-base medium corrosion, suitable for seawater cooling systems and ballast water systems.
Fluid optimization: smooth inner cavity flow channel (Ra≤1.6μm), reducing turbulence and improving medium flow efficiency.
Application: ship fuel system, ballast water system, fire fighting pipeline, etc.
Customized design: supports non-standard flange size and pressure level customization.
Lightweight: topological optimization structure, 15% lighter than traditional casting.

3. Pump parts (impeller, housing)
Function: used for ship seawater pumps, cooling pumps, etc., to ensure efficient and stable fluid delivery.
Wear and corrosion resistance: duplex stainless steel 2205 material, resistant to seawater erosion and corrosion, life increased by 50%.
High precision: impeller dynamic balance level reaches G6.3 (ISO 1940), stable operation, low noise.
High efficiency: fluid dynamics optimization design, efficiency is 10%-15% higher than ordinary pump parts.
Application: ship main engine cooling pump, ballast water pump, fire fighting pump, etc.
Anti-cavitation: special surface hardening treatment to reduce cavitation damage.
Modular design: easy to quickly replace and repair, reducing maintenance costs.

Application Scenarios
Commercial ships: cabins and piping systems of container ships, bulk carriers, tankers, etc.
Marine engineering: drilling platforms, FPSOs, and submarine pipelines.
