Tube platform (flat) How it works: pipe platform used, mainly for a variety of machinery and other products for various purposes test, measurement, calibration, welding, pipe platform typically designed plane, can be used for precision ruling. Tube platform use: Mainly used for a variety of uses various mechanical and other products test, measurement, calibration, welding, pipe platform typically designed plane, can be used for precision ruling, tube platform machinery manufacturing pipe inspection is indispensable The basic tools. Tube platform Material: high strength cast iron HT200-300, face hardness pipe platform for HB170-240, after two manual processing (annealing 600 degrees -700 degrees artificial and natural aging 2--3 years) use of the product accuracy and stability, good wear resistance. Tube platform accuracy: according to the national standard verification procedures, namely, 0,1,2,3 four grades. Tube platform packaging: iron packaging and wood packaging in two forms, tube platform surface with plastic film packaging, the packaging is suitable for combination pipe platform inland transportation, and there is good moisture, shock, rust and other measures to ensure safe arrival of a new pipe platform technology tube plate processing site, which is based on a flange screw angle data, with the flange plane crossed a method using the gauge flange, cast iron plate, spirit level, angle ruler heavy fall and other tools, the tube according to certain requirements on the platform positioning flange work, technical requirements, flat working surface may not have sand holes seriously affect the appearance and performance of pores, cracks, slag, shrinkage , scratches, bumps, rust and other defects. 2, the casting surface of the plate should be clear sand and smooth, painted solid. 3, precision registered as 0 - Class 3 flat work surface, the hole diameter of less than 15mm of sand allows the same material clogging hardness less than the hardness of the surrounding material. Face clogged sand hole should be limited to four, and the spacing between the holes of sand should not be less than 80mm. 4, the tube should be used to create high-quality fine flat gray cast iron or alloy material, its face hardness should 170-220HB. 5, flat working surface shall normally be by scraping process. Processing adopting scraping Face plate 3, the maximum allowable value of the surface roughness Ra 5um. 6, flat working surface flatness tolerances specified in Table 2. 7, flat working surface using scraping process should be painted on the research test. After the contact point of the research area ratio shown in Table 3 are predetermined: 25mm × 25mm square or press the contact area of ??a predetermined number of points are shown in Table 3, and should any of 25mm × 25mm between the contact point of not more than 5:00. In case of disputes, according to the ratio of the area of ??the contact point for the assessment basis. 8, the fluctuation amount of inconvenience for research using painted flat working surface inspection should examine their plane.
