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.

📌 Final Checklist for Choosing the Right Pipe
