紫銅(tong)墊(dian)片執(zhi)行標準以客戶提供的要求制作。紫(zi)銅墊片規格俗稱無氧銅,實心銅墊片采用機械切割等方式加工而成,其**的柔軟性可以填補法蘭表面的不平整部位。
應用(yong)溫(wen)度(du)范圍(wei)廣泛,低(di)泄(xie)漏。我們提(ti)供各(ge)種規格(ge)和型式實心銅(tong)(tong)墊片(pian)(pian),同(tong)(tong)時根據客戶要求選擇不(bu)同(tong)(tong)的銅(tong)(tong)產品制造墊片(pian)(pian),例如:紫銅(tong)(tong)、黃(huang)銅(tong)(tong)等。銅(tong)(tong)墊片(pian)(pian)性能:使用(yong)溫(wen)度(du):500℃左右,熔點:1083℃,硬度(du):淬(cui)火(huo)前≥60HB,淬(cui)火(huo)后≤45HB
銅質密封墊片 紫銅墊(dian)片(pian)具有很好的密封性能,可經冷、熱塑性加工制成各種半成品和成品,確保金屬面與法蘭密封面緊密貼合。適用的**高溫度是800度。適用壓力2.0Mpa-42mpa。紫(zi)銅墊片退火的目的是將其軟化。當需要對其進行折彎是為了防止斷裂及縮孔(管料),需要退火。如果只是密封,不需要退火。安裝時只要緊固,就可以密封。你可以試裝一下,就可以得出結果。金屬包覆墊片的一種,具有良好的耐腐蝕性,耐磨性和抗壓性更加突出.紫銅(tong)墊片主要應用于石油、化工、機械、冶金、電力、造船及管道、閥門、泵、壓力容器、冷凝器、塔、人孔、手孔等法蘭連接處,作靜密封之用。
由于(yu)機械強(qiang)度高,使(shi)用方便,壓縮回彈性(xing)好,銅(tong)(tong)(tong)質密(mi)(mi)封(feng)墊片更適合在劇(ju)烈的(de)(de)溫度交變場合應用。采用優質的(de)(de)紫銅(tong)(tong)(tong)板材具備良好的(de)(de)焊(han)接性(xing),可經冷、熱(re)塑性(xing)加(jia)工制成各(ge)種(zhong)半(ban)成品(pin)和成品(pin),經數控車床精密(mi)(mi)車削確(que)保密(mi)(mi)封(feng)面(mian)平直不翹曲,高精度研磨確(que)保金屬面(mian)與法蘭密(mi)(mi)封(feng)面(mian)緊密(mi)(mi)貼合。退火板材的(de)(de)室溫抗(kang)拉強(qiang)度為22~25公斤力/毫 米2,伸長(chang)率為45~50%,布(bu)氏硬度(HB)為35~45。可以滿足(zu)客戶(hu)的(de)(de)淬(cui)火、酸(suan)洗等各(ge)種(zhong)要求。使(shi)用溫度小(xiao)于(yu)400℃ 材料選擇: 銅(tong)(tong)(tong)Hpb59-1,H62,H65,H68(RoHS)環保銅(tong)(tong)(tong),紫銅(tong)(tong)(tong),硅青(qing)銅(tong)(tong)(tong),各(ge)種(zhong)鋁(lv)青(qing)銅(tong)(tong)(tong),錫青(qing)銅(tong)(tong)(tong),錳青(qing)銅(tong)(tong)(tong),錳黃銅(tong)(tong)(tong),鉻鋯銅(tong)(tong)(tong)等。
因為要檢驗紫銅墊片密封的作用,所以要檢驗其兩面的平整度,不能有凹陷,變形,裂痕和劃痕。這種墊片采用的原材料是紫銅 因呈紫紅色而得名。它不一定是純銅,有時還加入少量脫氧元素或其他元素,以改善材質和性能,因此也歸入銅合金。
