AAC autoclave for AAC Blocks

 AAC Autoclave for AAC Block

AAC is a lightweight, precast, foam concrete building material suitable for producing concrete masonry unit (CMU) like blocks. Composed of quartz sand, calcined gypsum, lime, cement, water and aluminum powder, AAC products are cured under heat and pressure in an autoclave. Invented in the mid-1920s, AAC simultaneously provides structure, insulation, and fire- and mold-resistance. Forms include blocks, wall panels, floor and roof panels, cladding (façade) panels and lintels.

AAC products may be used for both interior and exterior construction, and may be painted or coated with a stucco or plaster compound to guard against the elements, or covered with siding materials such as veneer brick or vinyl siding. In addition to their quick and easy installation, ACC materials can be routed, sanded, or cut to size on site using standard power tools with carbon steel cutters.

Materials must be chemically tested to determine its composition before storage.

Dimensional review and thickness inspection before storage.

The welding test plate shall be subjected to the pull-up and bending test, and the welding shall be carried out after the evaluation.

Autoclave shell plate use double fixed plate (only one welding line)

All parts of the autoclave are cut by CNC, which ensures smooth transition of the cut surface without burrs.

The autoclave shell is made of a large-scale thick-plate bending machine and can be rolled up to a thickness of 60 mm.

After the longitudinal weld of the shell is completed, the shell shall be rounded by the bending machine, and the ovality is guaranteed to be within 10% of the inner diameter of the shell.

Main pressure component welding wire :H10Mn2  flux :HJ431   

welding rod:J507

Automatic submerged arc welding machine 16 sets

Manual arc welding machine 58 sets

End dish and forging are X-ray inspected, , which meets the Class II qualification standard.

Forging flange(teeth) does magnetic particle inspection

The detection film is 100% tested by professional certified film reviewer, and can only enter the follow-up session after passing the test.

After the autoclave is completed, a water pressure test of 2.1 MPa must be performed.

The Special Equipment Inspection Institute tests all pressure parts during manufacturing.
