The GB/T 31929 standard outlines the requirements for Stainless Steel Tube Welded Stainless Steel Square Pipes designed specifically for Shipbuilding applications. These pipes are crafted with high-quality materials and adhere to stringent specifications to ensure reliable performance in maritime environments. The key features of these welded stainless steel pipes are their durability, corrosion resistance, and ability to withstand harsh conditions - qualities essential for shipbuilding operations.
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.08 max |
| Manganese (Mn) | 2.00 max |
| Phosphorus (P) | 0.045 max |
| Sulfur (S) | 0.030 max |
| Silicon (Si) | 1.00 max |
| Chromium (Cr) | 18.0-20.0 |
| Nickel (Ni) | 9.0-11.0 |
The chemical composition of these stainless steel pipes plays a vital role in enhancing their performance and longevity in shipbuilding applications.
| Property | Value |
|---|---|
| Tensile Strength | 600 MPa min |
| Yield Strength | 250 MPa min |
| Elongation | 35% min |
| Hardness | 90 HRB max |
The mechanical properties of these pipes are crucial as they determine the overall strength and structural integrity required for shipbuilding operations.
The steel grade specified in GB/T 31929 for these stainless steel Square pipes is typically grade 316, known for its excellent corrosion resistance and durability in marine environments.
The GB/T 31929 Stainless Steel Square Pipes are primarily used in shipbuilding due to their superior properties that are essential for maritime applications. These pipes are utilized in various marine systems onboard ships, providing a reliable solution for fluid conveyance and structural support.
While grade 316 is commonly prescribed in GB/T 31929, alternative stainless steel grades like 304, 316L, and 317L can be considered based on specific requirements and environmental conditions for shipbuilding applications. These alternative grades offer varying levels of corrosion resistance, strength, and other characteristics that may suit different shipbuilding needs.
