How to Choose the Right Reactor Material for a Pyrolysis Machine？

Selecting the right reactor material is one of the most important decisions when purchasing a pyrolysis machine. As the core component of the system, the reactor operates under high temperatures for extended periods, so its material directly affects equipment safety, service life, maintenance costs, and overall production efficiency. The best choice should always be based on feedstock type, operating temperature, and investment budget.

For standard feedstocks such as waste tires and clean plastics (PE, PP, and PS) processed at temperatures below 450°C, Q245R carbon steel is a practical and economical solution. It offers reliable mechanical strength and stable performance under normal pyrolysis conditions, making it an ideal choice for most batch and semi-continuous recycling projects while keeping the initial investment under control.

If your project involves oil sludge, high-sulfur rubber, or long-term continuous production, 15CrMo alloy steel is a better option. Its excellent resistance to high temperatures, sulfur corrosion, and thermal fatigue helps extend reactor life and reduce maintenance frequency. Although the initial cost is higher, its durability often results in lower operating costs over the equipment’s lifetime.

For feedstocks containing chlorine or other highly corrosive substances, such as certain mixed plastic wastes, 310S stainless steel provides the highest level of protection. Its outstanding corrosion resistance and heat resistance ensure stable operation in demanding working environments, making it suitable for projects with strict reliability requirements.

At Huayin, reactor material is never recommended based on price alone. Our engineering team evaluates each customer’s raw materials, processing capacity, operating conditions, and production goals before recommending the most suitable reactor configuration. Whether you need an economical solution for waste tire recycling or a heavy-duty reactor for continuous industrial production, we provide customized pyrolysis equipment designed for long-term, stable operation.

Choosing the right reactor material is ultimately about finding the best balance between temperature, feedstock, and budget. A properly matched reactor not only improves equipment reliability and extends service life but also maximizes the return on your investment. If you are unsure which material is right for your project, Huayin can help you select the optimal solution based on your specific operating conditions.
