Whether you’re working on a home plumbing project, industrial system, or food-grade setup, choosing the right SUMWIN stainless steel pipes is critical for performance, durability, and safety. This guide will walk you through the key factors to consider so you can select the most appropriate type of pipe for your needs.
✅ 1. Understand the Application
The first and most important step is to define what the pipe will be used for:
| Application | Key Requirements |
| Drinking water systems | Corrosion resistance, hygiene, food-grade |
| Industrial piping systems | High pressure & temperature tolerance |
| Decorative use | Aesthetic finish, polish grade |
| Chemical transport | Resistance to specific chemicals |
🧱 2. Know the Pipe Types Offered by SUMWIN
SUMWIN provides various types of stainless steel pipes based on grade and manufacturing process:
| Pipe Type | Description |
| Welded Pipes | Economical, made by rolling and welding; ideal for most general applications |
| Seamless Pipes | Stronger, no welding joint; suitable for high-pressure or high-temperature use |
| Decorative Pipes | Designed for aesthetics (e.g., handrails, furniture) |
| Sanitary Pipes | Highly polished, food-grade; used in dairy, beverage, and pharmaceutical industries |
🔍 3. Choose the Right Steel Grade
Different grades offer different properties. Common ones include:
| Grade | Ideal For | Properties |
| 304 | Household & food-grade use | Corrosion-resistant, easy to weld |
| 316 | Marine or chemical exposure | Molybdenum is added for higher corrosion resistance |
| 201 | Low-cost decorative applications | Lower nickel content, less corrosion-resistant |
📏 4. Size and Wall Thickness
Select a pipe size based on your flow requirements and system pressure.
- Outer Diameter (OD): Must fit with fittings and system design
- Wall Thickness (SCH 10, SCH 40, etc.): Thicker walls handle more pressure
💡 Tip: For residential plumbing, 1/2″ to 2″ diameter pipes are most common.
🧪 5. Finish & Surface Treatment
Depending on where and how the pipe is used, finish matters:
| Finish Type | Where It’s Used |
| Mirror Polish | Decorative, visible applications |
| Matte / Brushed | Industrial, concealed applications |
| Pickled & Passivated | Sanitary or corrosion-critical areas |
🛒 6. Verify Certifications
Make sure the pipes meet international standards, like:
- ASTM A312 / A213
- ISO 9001
- EN Standards (Europe)
SUMWIN stainless steel pipes are usually certified for quality and safety—check product specs or ask the supplier.
