GORE-TEX ® GR ® Plate shaped sealing gasket

GORE-TEX ® GR ® Plate shaped sealing gasket

NO.:

1

Features:

GORE-TEX ® GR ® The expanded polytetrafluoroethylene (ePTFE) sealing gasket is made of patented technology with a strong and tough porous structure, greatly improving the tensile strength and heat resistance of PTFE, as well as its excellent chemical resistance due to its soft texture. Therefore, it is suitable as a gasket for pipeline flanges and valve seals in various chemicals and acid and alkali solutions. Our company can supply various sizes at any time.

可作為傳統(tǒng)石棉及硬質(zhì)純PTFE墊片的最佳替代品。GPRE-TEX?GR?膨體聚四氟乙烯(ePTFE)密封墊片是目前所有PTFE材質(zhì)中抗蠕變與抗冷流性能最佳的板狀密封墊片,質(zhì)地柔軟,易于止漏、安裝與拆換。適用于粗糙面或易碎玻璃面法蘭的密封,所需緊固力?。?bar),在壓力變動(dòng)環(huán)境下又可承受相當(dāng)大的內(nèi)壓,在315℃以下幾乎適合于任何化學(xué)品或化工制程的密封應(yīng)用。GORE-TEX?GR?板狀密封墊片不受蒸汽影響,且可承受急劇的溫度循環(huán)變化,故亦為鍋爐流體輸送管路的理想密封材料。

GORE-TEX?GR?板狀密封墊片是一種高密度纖維結(jié)構(gòu),受壓后高密度纖維結(jié)構(gòu)會(huì)互相纏結(jié),形成一種質(zhì)地致密的“類似固體”,不透氣、不透水,高溫下或長(zhǎng)期受壓后仍然質(zhì)地柔軟、性能穩(wěn)定,始終保持其高抗拉強(qiáng)度,且因抗蠕變性能極佳,故終可保持極佳的密封性。本產(chǎn)品有各種寬度和厚度,加工成型迅速簡(jiǎn)便,無(wú)須事先切割,故可現(xiàn)場(chǎng)施工。密封效果較傳統(tǒng)硬質(zhì)純PTFE墊片佳且所需緊固力低,可適用于所有金屬、塑膠及各種易碎法蘭面的密封。也可與天生齒型金屬墊片共同制作成適用于高溫高壓工況的新型齒型密封墊片。

GORE-TEX?GR?R硬質(zhì)板狀墊片

GORE-TEX?GR?R硬質(zhì)板狀墊片,采用特殊的專利處理工藝,使其比GORE-TEX?GR?板狀墊片的硬度理一步增加,這就使得安裝更為容易,特別是大型法蘭的安裝。GORE-TEX?GR?R硬質(zhì)板狀墊片提供了和傳統(tǒng)GORE-TEX?GR?板狀墊片一樣的卓越性能,如保持了很高的緊固系數(shù),極小的蠕變,較低的密封緊固力和優(yōu)良的順應(yīng)性,是膨體聚四氟乙烯墊片中唯一的硬質(zhì)墊片。

GORE-TEX?GR?板狀墊片在對(duì)粗糙法蘭表面進(jìn)行密封只需要很小的壓力緊力(ASTMF-37-B.3-pisg(2bar)內(nèi)部壓力,表面粗糙度500RMS)。
