SPECIAL GRADE FOR HIGH PRESSURES WITH GOOD

CREEP RESISTANCE AND GOOD GAS TIGHTNESS

(DIN 28091 FA–MA1/-0)

TECHNICAL CHARACTERISTICS

This is a further development of our proven tested

CENTELLEN? WS 3820. CENTELLEN? HD-3822 was develo ped particularly for applications that would mechanically over burden our CENTELLEN? WS 3820 grade. Due to a similar

structure, the resistance data for CENTELLEN? WS 3820 can

be assumed for CENTELLEN? HD 3822 as well. The material

basis of CENTELLEN? HD 3822 consists of high grade arami de and anorganic fibres as well as mineral reinforcement

materials bonded with NBR rubber. This combination of raw

materials gives the following material characteristics:

?High compressive strength

?Very low gas leakage

?Very good oil resistance

?Good tensile strength

CENTELLEN? HD 3822 is produced according to the calender

process and is given a thin anti-adhesive surface when produ ced. The chemical properties are not affected by this process.

APPLICATIONS

Due to these material characteristics, seals made of

CENTELLEN? HD 3822 can be used wherever extreme condi tions in the form of higher pressure and medium temperature

strain exist. Typical applications are pipes in the general che mical industry, the systems, apparatures and machines buil ding industry, in the sanitary industry and in the food and

beverage industry.

具有良好的抗蠕變性和良好的氣密性的高壓專用級別(din 28091 fa-ma1 /-0)

技術特征這是我們的測試中心的進一步發(fā)展3820。Centellen hd-3822特別適用于機械加重我們的centellen ws 3820等級的應用。 由于相似的結構，可以假設centellen hd 3822的阻力數(shù)據(jù)也是centellen ws 3820。 中心hd 3822的材料基礎由高檔芳綸和無機纖維以及礦物增強材料與丁腈橡膠粘接而成。 這種原材料的組合賦予了以下材料特性:

?高抗壓強度

?非常低的氣體泄漏

?非常好的耐油性

?良好的抗拉強度

根據(jù)壓延工藝生產(chǎn)hd 3822，生產(chǎn)時表面具有薄薄的抗粘性。 化學性質(zhì)不受這個過程的影響。

由于這些材料的特性，只要存在較高壓力和中等溫度應變的極端條件，就可以使用由centellen hd 3822制成的密封。 典型的應用是管道在一般化學工業(yè)，系統(tǒng)，儀器和機械建筑工業(yè)，在衛(wèi)生行業(yè)和食品和飲料行業(yè)。
