Import Diameter Of 2.85 M Autoclave — Buy in Bulk from Supplier in China

This autoclave has a diameter of 2.85 metres and is designed for continuous curing of aerated concrete blocks under high-pressure steam conditions. It features a cylindrical pressure vessel constructed from welded steel, with internal insulation and a door mechanism designed for frequent opening and sealing. The unit is built to handle operational cycles of up to 12 hours, with temperature control maintained within ±5 °C of the set point.

The pressure vessel is typically fabricated from Q345R steel with a wall thickness of 28 to 35 mm, consistent with industry norms for vessels of this size and pressure rating. Insulation layers use ceramic fibre blankets with a density of 160 kg/m³ and thermal conductivity below 0.06 W/mK. The door seal is a double-lip silicone gasket rated for 220 °C, and the control system includes digital temperature sensors with data logging capability.

This autoclave is used by medium to large-scale AAC block producers seeking higher throughput than smaller units can provide. Buyers in India, Vietnam, and Nigeria commonly source this size for new plants or plant expansions. The unit is shipped in modular sections for container transport. Trade terms are usually FOB Qingdao or CIF, with packaging designed to protect flanges and electrical components. Buyers should confirm the maximum allowable working pressure and whether the vessel is stamped with a CE or ASME mark.

Zheng Zhou Zheng Guo Vessel Co., Ltd. is listed as an imported supplier with harbor trust tier, indicating basic export documentation compliance but no verified production capacity or customer feedback. The company's registered address is in Zhengzhou, Henan, a region known for pressure vessel manufacturing. The listing does not state the number of employees, years in business, or export history.

No certifications such as ISO 9001, PED, or ASME are confirmed. The source does not mention engineering drawings, weld procedure qualifications, or third-party inspection reports. Buyers must assume this supplier provides standard industrial vessels without documented quality assurance beyond basic export readiness. Independent verification of design and materials is strongly advised.
