When choosing materials for a pyrolysis reactor, several key factors must be considered: temperature resistance, corrosion resistance, mechanical strength, and cost-effectiveness. At Beston Group, we use different materials based on the type of reactor:
- Plastic/Oil Sludge/Tyre Pyrolysis Reactors: primarily use Q345R or 310SS.
- Biochar Pyrolysis Reactors: mainly use Q245R or Q245 +310SS.
Now let’s focus on Q245R, Q345R, 304SS, and 310SS to find their different properties and suitable scope.
4 Types of Pyrolysis Reactor Materials Available at Beston Group
Q245R
Type: Carbon steel
Properties:
- Moderate strength.
- Good weldability and malleability.
- Suitable for low to medium-temperature applications.
Applications: Typically used in pressure vessels and boilers operating at lower temperatures.
Advantages:
- Cost-effective.
- Adequate for less demanding applications.
Q345R
Type: Low-alloy Steel
Properties:
- Higher strength compared to Q245R.
- Enhanced toughness and weldability.
- Suitable for medium to high-temperature applications.
Applications: Pressure vessels, boilers, and tanks that require better mechanical properties and moderate temperature resistance.
Advantages:
- Improved mechanical strength.
- Better performance under pressure compared to Q245R.
304SS (304 Stainless Steel)
Type: Austenitic Stainless Steel
Properties:
- Good corrosion resistance, especially in mild environments.
- Good formability and weldability.
- Resistant to oxidation at temperatures up to 870°C.
Applications: Used in the construction of pyrolysis reactors exposed to moderate temperatures and non-corrosive or mildly corrosive substances.
Advantages:
- Balance of strength and corrosion resistance.
- Suitable for a wider range of applications compared to carbon steel.
310SS (310 Stainless Steel)
Type: Austenitic Stainless Steel
Properties:
- Excellent resistance to oxidation and scaling at temperatures up to 1150°C.
- High chromium and nickel content for superior corrosion and heat resistance.
Applications: Ideal for high-temperature environments, such as pyrolysis reactors operating at elevated temperatures.
Advantages:
- Superior performance in high-temperature and corrosive environments.
- Maintains strength and stability at elevated temperatures.
Future Potential Development for Pyrolysis Reactor Materials
According to customer demand, we may consider offering higher-grade corrosion-resistant materials like 316SS. 316SS (316 Stainless Steel) has higher corrosion resistance than 304SS/310SS due to added molybdenum. It excels in resisting chloride-induced corrosion and pitting, making it ideal for environments exposed to seawater or corrosive chemicals. In short, Beston Group offers custom configurations for customers, ensuring optimal pyrolysis performance and reactor durability.
