爆(bao)破片厂家选(xuan)型时会(hui)要求提(ti)供工(gong)作压力、工(gong)作温度、介质及相态、爆(bao)破压力、爆(bao)破温度、有无安全阀(fa)串联、有无负压等工(gong)况参数。

比如以下这些情况都会影响厂家对爆破片型号的选择：

1：泄(xie)放(fang)(fang)系统对于(yu)爆(bao)破(po)(po)片(pian)(pian)(pian)碎片(pian)(pian)(pian)的(de)(de)要求。泄(xie)放(fang)(fang)介质易燃易爆(bao)时，爆(bao)破(po)(po)片(pian)(pian)(pian)爆(bao)破(po)(po)后(hou)产(chan)生(sheng)(sheng)的(de)(de)碎片(pian)(pian)(pian)可(ke)能(neng)与泄(xie)放(fang)(fang)管道(dao)产(chan)生(sheng)(sheng)撞击火花，进(jin)而引燃介质，产(chan)生(sheng)(sheng)所(suo)谓的(de)(de)二次(ci)爆(bao)炸，导致严重的(de)(de)后(hou)果。当爆(bao)破(po)(po)片(pian)(pian)(pian)串联(lian)安(an)装在安(an)全阀(fa)入口侧时，爆(bao)破(po)(po)片(pian)(pian)(pian)爆(bao)破(po)(po)后(hou)如果产(chan)生(sheng)(sheng)碎片(pian)(pian)(pian)可(ke)能(neng)会使安(an)全阀(fa)堵塞，在这种(zhong)情况(kuang)下要求爆(bao)破(po)(po)片(pian)(pian)(pian)爆(bao)破(po)(po)后(hou)不能(neng)产(chan)生(sheng)(sheng)碎片(pian)(pian)(pian)。

2：泄(xie)放介(jie)(jie)质(zhi)的相(xiang)态。当(dang)泄(xie)放介(jie)(jie)质(zhi)为(wei)纯液相(xiang)时，一(yi)般不宜选用(yong)反拱(gong)型爆(bao)破(po)片，推荐选用(yong)正拱(gong)形爆(bao)破(po)片。

3：爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)片(pian)(pian)的(de)(de)爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)压(ya)(ya)力(li)与泄(xie)放(fang)直径。当爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)压(ya)(ya)力(li)很(hen)(hen)高时，一般不宜选(xuan)择反(fan)(fan)拱型(xing)爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)片(pian)(pian)。在较低(di)(di)的(de)(de)爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)压(ya)(ya)力(li)下，爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)片(pian)(pian)的(de)(de)厚度(du)很(hen)(hen)小，对于反(fan)(fan)拱型(xing)爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)片(pian)(pian)来(lai)说比(bi)较容易(yi)达(da)到失(shi)稳反(fan)(fan)转立(li)即爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)。根(gen)据(ju)结构界定的(de)(de)反(fan)(fan)转时文后致破(po)(po)(po)(po)(po)的(de)(de)难易(yi)程度(du)，反(fan)(fan)拱鳄齿型(xing)比(bi)反(fan)(fan)拱带刀(dao)形适用的(de)(de)压(ya)(ya)力(li)更低(di)(di)。带槽型(xing)爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)片(pian)(pian)不宜勇子压(ya)(ya)力(li)很(hen)(hen)低(di)(di)的(de)(de)场合(he)，以免爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)片(pian)(pian)厚度(du)太小，给爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)片(pian)(pian)的(de)(de)制造(zao)造(zao)成困难。正拱开缝(feng)型(xing)爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)片(pian)(pian)适用于压(ya)(ya)力(li)很(hen)(hen)低(di)(di)的(de)(de)场合(he)，当爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)片(pian)(pian)的(de)(de)泄(xie)放(fang)口径很(hen)(hen)小时，选(xuan)用正拱开缝(feng)型(xing)和反(fan)(fan)拱带刀(dao)形爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)片(pian)(pian)，或(huo)者泄(xie)放(fang)直径很(hen)(hen)大(da)时选(xuan)用带槽型(xing)爆(bao)(bao)(bao)(bao)破(po)(po)(po)(po)(po)片(pian)(pian)都会给制造(zao)带来(lai)困难。

4：应该根(gen)据具体的工(gong)(gong)作工(gong)(gong)况(kuang)对爆破片进行(xing)选(xuan)(xuan)型。此(ci)外，当爆破片的爆破温(wen)度不能准确确定时，宜选(xuan)(xuan)用反(fan)拱型爆破片。

此(ci)外，使用(yong)方对于(yu)价(jia)格(ge)的(de)要(yao)求也会(hui)影响(xiang)厂(chang)家对爆破片(pian)型号的(de)选择，特殊材质的(de)价(jia)格(ge)要(yao)高于(yu)喷涂或(huo)者衬氟的(de)。
