Sitong autoclave is large pressure vessel for steam curing, has excellent thermal insulating quality, and it is easy installed. Mostly, it is used for autoclaved aerated concrete plant (AAC plant) and wood preservation (or other wood processing). The autoclave is a horizontal cylinder device, when curing the aerated concrete, there is hydrothermal reaction (CaO-SiO2-H2O) happened in autoclave. Wood preservation autoclave could also be applied to different wood processing, such as fire retardant, mothproof, dyeing, coking, and degrease, etc. It has the advantages of wide applicability, good treat efficiency, large capacity, reasonable layout, and safety operation, etc. Based on customers’ requirement, the autoclave door could designed as manual and automatic operation.

Except AAC plant and wood preservation, the autoclave could also be used for maintenance and steaming of lime-sand brick, fly-ash brick, new light wall material, concrete tubular pile and other building products, moreover, it can used for the products steaming in chemical industry, medicine, rubber, wood corrosion prevention, gypsum, glass, thermal insulation materials, textile, war industry and other area. Sitong boiler could design and manufacture various forms of autoclave according to customers’ requirements.

Aerated concrete technical process                                                                  Wood preservation technical process

Add wood preservative into autoclave -- push the wood into the autoclave -- treatment -- imbibition
-- inflating -- keep the pressure -- decompression -- discharge wood preservative -- wood leaving autoclave--inspect

Characteristics of Autoclave

High Quality Assurance
1) There is a professional design engineer team, before manufacturing, every boiler design drawing have to be approved by boiler and pressure vessel experts of CSBTS ( State Bureau of Quality Technical Supervision ), and then the boiler could be produced only if qualified.
2) To ensure the raw materials quality, all the steel plates are special-used for boiler with the Inspection Certificates. The raw material materials are inspected when entering factory, and only the qualified material could be put in storage and used for production.
3) To ensure the welding quality, there a professional welding team, including more than 30 senior welders. The welding materials are stored under constant temperature and humidity, to ensure the welding material quality.

4) The welding quality will be further examined during boiler manufacturing, by using x-ray detection, ultrasonic flaw detection, magnetic test, or penetration test, etc.
5) To ensure the boiler quality, the leakproofness and strength of pressure parts will be tested. The hydrostatic test is done to make sure there are no water drop or water mist leakage appear on steal wall or welding joint, no water leakage appear at the place of expansion, and no obvious residual deformation and abnormal situation.
6) To ensure no problems before boiler delivery, all the raw materials and boilers are supervised and inspected by the experts of Inspection Institution for Boiler and Pressure Vessel. There are international uality certificates of ISO 9001 and CE, we can also offer the inspection report of SGS, BV, etc., Quality Certificates, Energy audit report, and Energy Efficiency Test Report, etc.

Professional Installation and After-sale Service Team

1) Professional engineer installation team offer the door to door installation and after sale service. The boilers will operate smoothly and safety, and you will get them without worries.
2) 24 hours hot-line to solve your problems, and offer the professional technical supports and after sale service in time to all over the world.
