在法兰垫外观设计上为了安装方便,本公司根据垫片口径大小,在垫片外围焊上2~8个定位带,让定位带扣在法兰孔上,以防安装时垫片移位或脱落,节约了辅助材料及工时.
垫片种类及材料
　　1、缠绕式垫片分为四种形式：即A为基本型，B为带内加强环型，C为带外加强环型，D为带内、外加强环型。
　　2、一般使用材料
　　A、钢带：0Cr13、0Cr18Ni9(304)、0Cr18Ni9Ti、1Cr18Ni9Ti(321)、0Cr17Ni12Mo2(316)、　00Cr17Ni14Mo2(316L)
　　B、内外环用材料有A3、304、316、316L
　　C、非金属夹层带：柔性石墨聚四氟乙烯、特制石棉。
mix:
The flange on the pad designs to facilitate the installation of the Company under the gasket-caliber size, the gasket external welding a 2 ~ 8 positioning belt buckle for positioning hole in the flange, to prevent displacement installation gasket or falling out of the supporting material and saving hours of work.
Types and gasket materials
1, Winding pads pided into four forms: that is, as the basic type A, B band strengthen ring, the C-band to strengthen the ring, the D-band, the strengthening ring.
2, the general use of materials
A strip: 0 Cr13, 0Cr18Ni9 (304), 0Cr18Ni9Ti, 1Cr18Ni9Ti (321), 0Cr17Ni12Mo2 (316), 00Cr17Ni14Mo2 (316L)
B, both inside and outside ring materials are A3, 304,316,316 L
C, non-metallic sandwich belt: Flexible Graphite PTFE, custom-made asbestos.

使用范围： Use of:
1、使用温度：-196℃-650℃ 1, the use of Temperature: -196 ° C -650 ° C
（氧化介质中不高于450℃） Oxidation medium does not exceed 450 ° C)
2、使用压力 ≤ 25MPa 2, the use of pressure ≤ 25MPa
3、垫片厚度：2.5-4.5mm 3, gasket thickness :2.5-4.5 mm

性　　能：
　　1、适用范围广。能耐高温、高压和适应超低温或真空下使用。
　　2、应用补偿能力强。在高温、高压波动频繁的工位上，密封性能稳定、可靠性强。
　　3、有良好的密封性能。
　　4、使用安装方便。
Performance:
1, the scope of application-Canton. Can high temperatures, high pressure and adapt to ultra-low-temperature vacuum or use.
2, the ability of compensation. At high temperature, high pressure fluctuations frequent-position, the sealing performance stability and reliability.
3, a good sealing performance.
4, the use of the installation convenience.
