玻璃钢法兰制作规范一、玻璃钢法兰制作规范(法兰盘厚度要求、制作过程和铺层设计)1、总则本标准的制订旨在明确玻璃钢法兰生产制作基本规范,以稳定玻璃钢法兰生产质量。2、适用范围玻璃钢法兰生产制作3、工艺流程简图4、法兰制作标准4.1法兰模具的准备4.1.1将法兰模具制作表面清理干净,有锈迹的需用砂纸打磨干净;4.1.2在模具制作表面涂抹脱模蜡;4.1.3将模具用水平尺调校水平;4.2原材料和接管的准备根据模具尺寸,将表面毡、短切毡、方格布等纤维制品剪切成所需尺寸的环形或条形;将接管插入模具端切割垂直整齐。4.3法兰壳体的制作合格不合格法兰模具的准备原材料接管准备制作法兰壳体法兰第一次增强脱模检测返工法兰增强、R角制作按法兰标准打眼后处理检测入库使用防腐树脂(与制作设备或管道内衬层相同的树脂)和裁剪好的纤维制品在模具内按铺层依次铺设制作,并用气泡滚将其中的气泡赶尽,不允许有缺胶或烧灼等不良现象。再用增强树脂和纤维进行第一次增强。4.4法兰脱铜检测水线面,进行增强层和R角制作将法兰从模具中脱出,对其水线外表面进行检测,要求水线面不允许有缺损或气泡;检测合格后按铺层设计进行强度层和R角的制作。4.5按照法兰相关标准打眼。4.6对打眼后的法兰进行最后的处理,即打磨掉毛边,外表面涂刷树脂。4.7成品检测入库。附录1法兰制作层次示意图附录2法兰制作尺寸及铺层设计1、0.6MPa法兰序号法兰规格厚度mmLmmHmm法兰结构铺层壳体脱模前增强脱模后增强R角外表层1DN50184570表面毡+(1毡+1层04布)*2/缠绕纱(一次加厚不超过10mm)+1毡+2层04布(R角增强)直至法兰所要求厚度减去R角外表层毡的厚度。(其中DN25-DN80不允许使用缠绕纱加厚)2毡2DN651847.570表面毡+(1毡+1层04布)*2/2毡3DN802052.580表面毡+(1毡+1层04布)*2/2毡4DN1002052.5100表面毡+(1毡+1层04布)*2(1毡+2层04布)*22毡5DN1252255100表面毡+(1毡+1层04布)*2(1毡+2层04布)*22毡6DN1502255100表面毡+(1毡+1层04布)*2(1毡+2层04布)*22毡7DN2002457.5125表面毡+(1毡+2层04布)*2(1毡+3层04布)*23毡8DN2502460125表面毡+(1毡+2层04布)*2(1毡+3层04布)*23毡9DN3002667.5125表面毡+(1毡+2层04布)*2(1毡+2层04布)*23毡10DN3502667.5125表面毡+(1毡+2层04布)*2(1毡+2层04布)*23毡11DN4003067.5150表面毡+(1毡+2层04布)*2(1毡+2层04布)*23毡12DN4503070150表面毡+(1毡+2层04布)*2(1毡+3层04布)*23毡13DN5003470150表面毡+(1毡+1层04布)*2(1毡+2层04布)*23毡14DN6003677.5150表面毡+(1毡+1层04布)*2(1毡+2层04布)*23毡15DN7003680180表面毡+(1毡+1层04布)*2(1毡+2层04布)*33毡16DN8004087.5180表面毡+(1毡+1层04布)*2(1毡+2层04布)*33毡17DN10004087.5200表面毡+(1毡+1层04布)*2(1毡+2层04布)*33毡18DN12004445200表面毡+(1毡+1层04布)*2(1毡+2层04布)*43毡19DN14004447.5200表面毡+(1毡+1层04布)*2(1毡+2层04布)*43毡注:R角制作尺寸达到L尺寸处,R角制作完成凝胶后外表面涂刷2遍树脂,使外表面光滑平整,要求法兰盘厚度均匀。2、1.0MPa法兰序号法兰规格厚度mmLmmHmm法兰结构铺层壳体脱模前增强脱模后增强R角外表层1DN50205570表面毡+(1毡+1层04布)*2/缠绕纱(一次加厚不超过10mm)+1毡+2层04布(R角增强)直至法兰所要求厚度减去R角外表层毡的厚度。(其中DN25-DN80不允许使用缠绕纱加厚)2毡2DN652057.570表面毡+(1毡+1层04布)*2/2毡3DN802257.580表面毡+(1毡+1层04布)*2/2毡4DN1002257.5100表面毡+(1毡+1层04布)*2(1毡+2层04布)*22毡5DN1252460100表面毡+(1毡+1层04布)*2(1毡+2层04布)*23毡6DN1502467.5100表面毡+(1毡+1层04布)*2(1毡+2层04布)*23毡7DN2002667.5125表面毡+(1毡+2层04布)*2(1毡+3层04布)*23毡8DN2502670125表面毡+(1毡+2层04布)*2(1毡+3层04布)*23毡9DN3003070125表面毡+(1毡+2层04布)*2(1毡+2层04布)*23毡10DN3503075125表面毡+(1毡+2层04布)*2(1毡+2层04布)*23毡11DN4003482.5150表面毡+(1毡+2层04布)*2(1毡+2层04布)*23毡12DN4503682.5150表面毡+(1毡+2层04布)*2(1毡+3层04布)*23毡13DN5003685150表面毡+(1毡+1层04布)*3(1毡+2层04布)*23毡14DN6004090150表面毡+(1毡+1层04布)*3(1毡+2层04布)*23毡15DN7004097.5180表面毡+(1毡+1层04布)*3(1毡+2层04布)*33毡16DN80044105180表面毡+(1毡+1层04布)*3(1毡+2层04布)*33毡17DN100044110200表面毡+(1毡+1层04布)*3(1毡+2层04布)*33毡18DN12005055200表面毡+(1毡+1层04布)*3(1毡+2层04布)*34毡19DN14005057.5200表面毡+(1毡+1层04布)*3(1毡+2层04布)*34毡注:R角制作尺寸达到L尺寸处,R角制作完成凝胶后外表面涂刷2遍树脂,使外表面光滑平整,要求法兰盘厚度均匀。3、1.6MPa法兰序号法兰规格厚度mmLmmHmm法兰结构铺层壳体脱模前增强脱模后增强R角外表层1DN50225570表面毡+(1毡+1层04布)*2/缠绕纱(一次加厚不超过10mm)+1毡+2层04布(R角增强)直至法兰所要求厚度减去R角外表层毡的厚度。(其中DN25-DN80不允许使用缠绕纱加厚)2毡2DN652257.570表面毡+(1毡+1层04布)*2/2毡3DN802457.580表面毡+(1毡+1层04布)*2(1毡+2层04布)*22毡4DN1002457.5100表面毡+(1毡+1层04布)*2(1毡+2层04布)*22毡5DN1252660100表面毡+(1毡+1层04布)*2(1毡+2层04布)*23毡6DN1502665100表面毡+(1毡+1层04布)*2(1毡+2层04布)*23毡7DN2003067.5125表面毡+(1毡+2层04布)*2(1毡+3层04布)*23毡8DN2503077.5125表面毡+(1毡+2层04布)*2(1毡+3层04布)*23毡9DN3003480125表面毡+(1毡+2层04布)*2(1毡+2层04布)*23毡11DN3503685125表面毡+(1毡+2层04布)*2(1毡+2层04布)*23毡12DN4003690150表面毡+(1毡+2层04布)*2(1毡+2层04布)*23毡13DN4504095150表面毡+(1毡+2层04布)*2(1毡+3层04布)*23毡14DN50040102.5150表面毡+(1毡+1层04布)*3(1毡+2层04布)*23毡15DN60044120150表面毡+(1毡+1层04布)*3(1毡+2层04布)*23毡注:R角制作尺寸达到L尺寸处,R角制作完成凝胶后外表面涂刷2遍树脂,使外表面光滑平整,要求法兰盘厚度均匀。国标法兰尺寸标准1.“机械工业部(JB81/83-94)”法兰连接尺寸表公称通径DNmm公称压力Pg(Kgf/cm2)2.56101625DD1ndDD1ndDD1ndDD1ndDD1nd401301004141301004141451104181451104181451104185014011014011016012516012516012565160130160130180145180145180145880(70)1851501818515018195160195160819516010020517020517021518082151802301902212523520082352008245210245210270220261502602252602252852402228024022300250200315280315280335295335295123603101225037033512370335123903501240535526425370303004353952243539522440400460410485430163504854454854455004601652047016550490334005354951653549516565515265805253061055045059055059055061556520640585206606002050064060064060067062070565033730660396007557052026755705202678072530840770398407707008608102486081024895840249108402495587524458009759203097592030101095033102095010709909001075102010751020111010502811201050281180109028521000117511202811751120281220116012551170451305121056120013751320321400134032331450138032391485139032521525142032140015751520361620156036167515903645168515903617501640364015001690163017201660------------160017851730401820176040191518204052193018204056----代号D-法兰外径mmn-螺栓孔个数D1-法兰螺栓孔中心圆直径mmd-螺栓孔直径mm2.国标(GB9112—9131—88)管法兰连接尺寸表公称通径DNmm公称压力PNMPa(bar)0.25(2.5)/0.6(6)1.0(10)1.6(16)2.5(25)2.0(20)DKnLDKnLDKnLDKnLDKnL4013010041415011041815011041815011041813098.541650140110165125165125165125150120.520651601301851451851451851458180139.5801901501820016082001608200160190152.510021017022018022018023519022230190.58125240200825021025021027022026255216221502652252852402228524022300250280241.52003202803402953402951236031012345298.5250375335123953501240535526425370304053621226300440395224454004604104854301648543235049044550546016520470165554903353547030400540495165
