Complete Material Specification of Batch Pyrolysis Equipment

1. Main Reactor (Core Vessel)

Outer Shell of Reactor

Material: Q245R boiler special pressure vessel steel plate

Application: Pressure-bearing outer structure with high temperature resistance, good toughness and thermal deformation resistance.

Inner Liner of Reactor (material contact layer)

Standard configuration: Q345R high temperature resistant pressure vessel carbon steel

Premium anti-corrosion version: 16MnR manganese steel

Features: High temperature resistance, thermal fatigue resistance and high temperature oxidation resistance. Suitable for high-temperature pyrolysis of waste tires, plastics and oil residue with low cracking risk.

Reactor flange and head

Material: Forged carbon steel flange + elliptical pressure vessel head, with stable sealing, pressure resistance and deformation resistance.

2. High-temperature Flue, Furnace Liner and Fire Passage

Material: Thickened heat-resistant cast steel / high temperature boiler steel

Withstands open flame heating for long term, resistant to high-temperature ablation and burn-through deformation.

3. Oil and Gas Transmission Pipeline

High-temperature pyrolysis gas pipeline (high-temperature section at reactor outlet)

Seamless 20# carbon steel high temperature resistant steel pipe

Medium and low temperature condensation pipeline

Ordinary seamless steel pipe

4. Condensing System

Condensing coil

20# high-quality seamless steel pipe, with fast heat conduction and oil-gas corrosion resistance.

Outer shell of condensing tower

Ordinary carbon steel plate

5. Tail Gas Pipeline and Tempering Device

Material: Carbon steel seamless pipe, equipped with explosion-proof and flame-retardant structure.

6. Oil Storage Tank and Oil-water Separator

Vessel material: Ordinary carbon steel plate

7. Support, Base, Ladder and Platform

Material: National standard square steel, channel steel and Q235 carbon steel, with stable structure and large load-bearing capacity.

8. Sealing Materials

High-temperature sealing gasket for reactor door: High temperature resistant graphite composite gasket, metal wound gasket

Valve seal: Oil-resistant and high temperature resistant rubber gasket

9. Special Materials for Corrosion-prone Parts

Upgraded materials for oil sludge, heavy oil and sulfur-containing hazardous waste raw materials:

High-temperature anti-corrosion coating can be applied on the inner wall of reactor.

304 stainless steel liner is optional for strong acid and heavy oil working conditions.

Stainless steel is unnecessary for ordinary waste tire and plastic pyrolysis. Carbon steel has better high temperature performance and higher cost performance.
