In order to prevent the deformation of the A105 Plate Flanges, when lifting the A105 Plate Flanges, four steel wires with the same length shall be used to hang the four lifting holes on the A105 Plate Flanges at the same time, and the flat flange shall be stably hoisted on the transportation tool. Pad and level the supporting points of the plate flange. Each supporting point is evenly stressed and the whole plate flange is stable. During the installation of flat flange, all support points of cast iron A105 Plate Flanges shall be padded and compacted with adjusting sizing blocks, and the flat flange shall be adjusted to qualified accuracy by technicians. When the A105 Plate Flanges is used, the workpiece shall be handled with care, and the rough workpiece shall not be moved on the A105 Plate Flanges, so as to avoid collision, scratch and other damage to the working surface of the A105 Plate Flanges.
In order to prevent the deformation of the A105 Plate Flanges body, take the workpiece off the A105 Plate Flanges after use to avoid the deformation of the cast iron A105 Plate Flanges caused by the heavy pressure of the workpiece on the A105 Plate Flanges for a long time. When the A105 Plate Flanges is not in use, the working surface shall be cleaned in time, then coated with a layer of antirust oil and covered with antirust paper. The cast-iron A105 Plate Flanges shall be covered with the outer package of the A105 Plate Flanges to prevent damage to the working surface of the A105 Plate Flanges caused by carelessness. The A105 Plate Flanges shall be installed in a ventilated and dry environment and away from heat source, corrosive gas and corrosive liquid. The working surface of A105 Plate Flanges shall be free of rust, scratch, bruise and other appearance defects that affect the use.
The working surface of A105 Plate Flanges shall be free of casting defects such as sand hole, air hole, crack, slag inclusion and shrinkage porosity. All casting surfaces shall be made of molding sand, with flat surface and firm paint.
