下面为美国 NELSON 公司生产的部分保温钉规格及其使用范围。1.单层衬里保温钉(1)S7X 型保温钉适用于低密度物料(640~1120公斤/米~3)的衬里,如烟道、烟囱、工艺炉等。使用温度820℃,保温钉的两支腿长度相等,材料为 Cr18Ni12,其主要尺寸如图1a 所示。也有采用图1b 型的.(2)RWP 型保温钉适用于低密度至中等密度物料(1280~1600公斤/米~3)的衬里,如烟囱、焚烧炉、再生炉等。使用温度1090℃。保温钉作成波形,可以增加与衬里的结合强度。保温钉焊后将支腿在开口处张开成60°角,其高度约降低13毫米。RWP 型保温钉也可用于双层衬里.材料为 lCr18Ni9,主要尺寸见图2。
The following is the United States NELSON part of the production of thermal insulation nail specifications and the scope of use. 1. Single-layer lining insulation nails (1) S7X insulation nails for lining of low-density materials (640 ~ 1120 kg / m ~ 3), such as flue, chimney, furnace and other technology. The operating temperature of 820 ℃, insulation nail two legs of equal length, the material is Cr18Ni12, the main dimensions shown in Figure 1a. (2) RWP thermal insulation nails are suitable for lining of low density to medium density materials (1280 ~ 1600 kg / m ~ 3), such as chimney, incinerator, regenerator and so on. Operating temperature of 1090 ℃. Insulation nails into a waveform, you can increase the bond strength with the lining. After the insulation nail welding will open the legs in the opening angle of 60 °, the height of about 13 mm lower. RWP insulation pin can also be used for double lining. Material lCr18Ni9, the main dimensions shown in Figure 2.
