Comparison Table of Copper Pipe Types
| Type | Wall Thickness | Common Applications | Flexibility | Connection Methods |
|---|---|---|---|---|
| Type K | Thick | Underground installations, water services, heating | Moderate | Sweat, flared, compression |
| Type L | Medium | Water supply lines, HVAC systems | High | Solder, sweat, compression |
| Type M | Thin | Residential plumbing, heating, and cooling systems | High | Solder, push-fit, compression |
| DWV | Varies | Drainage, waste, vent systems | Low | Solvent welding |
Types of Copper Pipe
Type K Copper Pipe: Overview
Type K copper pipe is characterized by its thick walls, making it the most robust option available. This type is commonly used for underground installations and areas where the pipe will be exposed to higher pressures and corrosive elements. Its ability to withstand harsh conditions makes it ideal for water services, plumbing, heating, and even gas applications.
Applications of Type K Copper Pipe
Type K pipes are particularly suited for:
- Underground Installations: Their thickness provides added durability against soil pressure and external impacts.
- Water Services: Used for main water lines due to their strength and resistance to corrosion.
- Heating Systems: Effective in both commercial and residential heating applications, ensuring reliable operation.
Comparison with Other Types
When compared to Type L and Type M, Type K offers superior strength but is less flexible. Type L, while still robust, is suitable for interior water supply lines, while Type M is designed for lighter applications, featuring thinner walls.
Technical Features of Type K Copper Pipe
| Feature | Specification |
|---|---|
| Outside Diameter | Varies (common sizes: 1/2″, 3/4″, 1″) |
| Wall Thickness | 0.040″ to 0.065″ (depending on diameter) |
| Pressure Rating | Up to 1000 PSI (varies by application) |
| Material | Copper (CDA 122) |
| Flexibility | Moderate (requires bending tools) |
Advantages of Using Type K Copper Pipe
- Durability: With thicker walls, Type K pipes are less prone to leaks and damage.
- Corrosion Resistance: Copper naturally resists corrosion, ensuring a long lifespan.
