材料來源所用材料由安裝單位按生產(chǎn)廠根據(jù)工況和介質(zhì)條件等提供的材料清單自行采購,也可由生產(chǎn)廠家提供。(1)sourcesofmaterialThematerialsusedbytheinstallationofunitsandplantsundertheconditionsofworkingconditionsandmediatoprovidealistofmaterialsontheirownprocurement,mayalsobeprovidedbythemanufacturer.(2) 原材料準(zhǔn)備按工藝單上的種類和數(shù)量,準(zhǔn)備好原材料。布和短切氈應(yīng)根據(jù)產(chǎn)品的規(guī)格尺寸,提前裁剪好。有鎖邊的布應(yīng)將鎖邊剪掉,短切氈的邊口用手撕毛。以上原材料須是檢測合格的方可使用。如有需要更換的材料或變動鋪層,需經(jīng)有關(guān)工藝員書面認可,方可變動。(2)RawmaterialpreparationAccordingtoprocessasingleonthetypeandquantityofrawmaterialsready.Clothandchoppedstrandmatproductspecificationsshouldbebasedonsize,aheadofagoodcut.Alockthelocksideedgeofclothshouldbecut,choppedstrandmatedgesofmouthShousihair.Theaboverawmaterialshallbetestedandmayuse.Ifnecessary,replacementmaterialsorchangesinshopfloor,subjecttowrittenapprovalofthecraftbeforetheychange.(3) 切割打磨根據(jù)圖紙,找出需對接的管道,并檢查規(guī)格、長度、壓力等級與設(shè)計要求是否相符。在需切割處用記號筆劃好切割線,用裝有金剛石砂輪片的角向磨光機將需膠接的部位切開,切口應(yīng)平整,切割尺寸誤差不大于2mm。(3)cuttingpolishingAccordingtodrawings,toidentifyingdockingpipeline,andchecksize,length,pressureratingisconsistentwiththedesignrequirements.Intheneedtodrawagoodcutatcuttinglinewiththemarker,usingfilmswithdiamondwheelanglegrinderwillneedtocutbondingsiteoftheincisionshouldbeflat,cutsizeoftheerrorisnotgreaterthan2mm.根據(jù)對接寬度將需膠接的地方用裝有軟片砂輪的角向磨光機進行打磨,切口處打磨坡度大于45。,并且應(yīng)磨到內(nèi)襯層(內(nèi)襯層厚度1.5-2.5mm)。Accordingtodockingwidthwillbegluedinplacewiththefilmwheelwithanglegrinderforgrinding,polishingincisionslopegreaterthan45°andshouldweartotheinnerlayer(lininglayerthickness1.5-2.5mm).對接定位按下圖將找正環(huán)(或膨脹環(huán))塞入一頭對接口,漲緊后,把另一接頭套在找正環(huán)上,然后將兩對接頭推緊合縫,對正找平,使中間的離縫盡可能地小,并用水平儀檢查管線是否水平,軸心線是否在同一直線上,方向是否正確,法蘭眼是否對正(如果有法蘭的話)。如果口徑較小(DN400以下)或無找正環(huán),亦可直接對正。(4)dockingorientationPressthemapwilllookforpositivering(orexpansionring)squeezedonepairsofinterfaces,uptight,putthecoverlookingfortheotherjointsarering,andthenpushthetwopairsofjointstightcommissure,rightnowleveling,sothatthemiddleawayfromtheslitassmallaspossible,andusethelevelofinstrumentcheckswhetherthelevelofpipeline,whethertheaxislinehasbeeninthesameline,thedirectioniscorrect,whethertheflangeeyesare(ifanyflangeso).Ifasmallerdiameter(DN400below)tofindpositiveornoring,ordirectlytothepositive.⑸配膠樹脂配方由生產(chǎn)廠家提供,在配制前,安裝者應(yīng)根據(jù)當(dāng)時的氣溫條件進行凝膠試驗,確定樹脂與固化劑、促進劑的配比。凝膠時間以25?45分鐘為宜,以整個工序操作完成后30?60分鐘固化為好。⑸withglueResinformulationsprovidedbythemanufacturer,inthepreparationbeforetheinstallersshouldbebasedonconditionsatthattimethetemperaturegeltesttodeterminetheresinandcuringagent,theratioofaccelerator.Geltimeis25~45minutesisappropriatetothewholeprocessiscomplete30to60minutesafterthecureisbetter.配制時,應(yīng)先用秤稱量或量杯準(zhǔn)確量取樹脂并加入促進劑(鉆鹽),攪拌均勻后再加入固化劑。為防止未操作完,樹脂提前固化,可分多次配制。PreparationshouldbethefirsttouseanaccuratebalaneeweighingormeasuringcupandaddtheamountofresinobtainedAccelerator(cobaltsalt),stirringevenafteraddingcuringagent.Topreventtheoperationisnotfinished,resincuringinadvanee,canbedividedintoseveralpreparation.※注意:嚴(yán)禁將固化劑與促進劑直接混合,直接混合將會發(fā)生燃燒,甚至爆炸。固化劑與促進劑在運輸、貯存及搬運時,也應(yīng)分離開來,并通風(fēng)、避光,否則也易發(fā)生火災(zāi)事故。探Note:Thecuringagentisstrictlyprohibiteddirectmixingwiththeaccelerator,directcombustionofmixingwilloccur,orevenanexplosion.Curingagentandacceleratorinthetransport,storageandhandling,wealsoshouldbekeptseparateandventilated,dark,orarepronetofireincidents.封口在接縫處,刷上內(nèi)襯樹脂,鋪上表面氈,將浸好膠的長絲繞在對接的縫隙內(nèi)。然后,鋪放兩層短切氈。這兩層短切氈應(yīng)鋪滿整個搭接面,應(yīng)用毛刷和輥輪,使之浸潤充分、滾壓平整、無氣泡和皺紋。⑹SealAttheseams,brushontheinnerresin,coveredwithcarpetsurfacewillbeagoodBaptistplasticfilamentwrappedaroundthebuttofthecracks.Then,layingtwolayersofchoppedstrandmats.Thisshouldbecoveredwithtwolayersofchoppedstrandmatsurfacethroughoutthelap,applicationbrushandrollerwheels,sothatinfiltrationfull,rollingflat,nobubblesandwrinkles.糊制待封口固化后,檢查封口質(zhì)量,有無氣泡、裂紋等缺陷,如有,則需打磨修復(fù),用打磨機將對接面打毛,將整個對接面刷上一層膠,根據(jù)工藝單上規(guī)定的搭接寬度和鋪層順序鋪放短切氈,纏繞玻璃布,每纏一層,用毛刷蘸上樹脂,使之浸透,用輥輪滾壓,趕盡氣泡并抹平,不得留有皺紋、未浸潤等不良情況。糊制時,對接口兩邊應(yīng)平整整齊。pastesystemTobesealedaftercuring,checkthesealofquality,withorwithoutairbubbles,cracksandotherdefects,ifany,itwouldtakepolishingrepair,willjunctionwiththegrindingmachinetoplayhair,brushontheentiredockingsurfacelayerofglue,accordingtotheprovisionsofasingleprocessoverlapwidthandstackingsequeneeplacementchoppedstrandmat,glassclothwinding,eachlayerwrappedwithabrushdippedinresin,sosoakedwithrollerrollingintimetomakebubblesanddisappearing,leavingnowrinkles,noinfiltrationandotherbadsituations.Pastesystem,theformationoftheinterfaceonbothsidesshouldbetidy.平端對接連接圖※應(yīng)強調(diào),糊制時,不能一次鋪放二層以上的鋪層,每次都應(yīng)用壓輥滾壓。對于0500以上的管的對接,可以分成兩次成型,但第一次成型時,兩端厚度須遞減,第二次成型與第一次成型須搭接,搭接寬度不得低于50mm。Itshouldbeemphasized,pastesystem,itcannotaplacementofmorethantwo-storyshopfloor,eachapplicationofpressurerollerrolling.Formorethan0500dockingtubecanbedividedintotwoforming,butthefirsttimewhenitformedatbothendsofthethicknesstobereduced,thesecondmoldingandshapingtobethefirstlap,lapwidthofnotlessthan50mm.凝膠前,最好留有專人看管,以防流膠,流膠處,應(yīng)及時補膠,膠淤積的地方,用毛刷將膠抹勻,直至凝膠。Gelbefore,itisbestlefthandguardtopreventtheflowofglue,plasticflowBranch,shallpromptlymakeupplastic,plasticsiltwheretheplasticMayunwithbrushuntilthegel.糊制完成必須保證工作面的整潔和防水,保證樹脂的完全固化成型。保證手糊部位48小時不和水接觸。Pastethesystemmustguaranteethecompletionofthecleanfaceandwaterproof,ensuringcompletecuringresinmolding.Ensurethathandlay-upareaandwaterfor48hoursnon-contact.固定支墩因管道采用平端對接連接,當(dāng)管線加壓后,在管線兩頭、彎頭、三通、變徑、盲端等許多地方會產(chǎn)生不平衡的應(yīng)力以及發(fā)生管線偏移等現(xiàn)象,如果周圍的土壤對管線不能提供足夠的約束力的話,極有可能造成管線的損害。所以,為了確保管線正常運行,避免上述現(xiàn)象的發(fā)生,必須采取措施來約束這種不平衡的應(yīng)力,預(yù)防管線的損害。通常采用的方法是用水泥固定墩固定。固定的水泥墩的尺寸可根據(jù)實際情況進行設(shè)計,以能滿足使用要求為準(zhǔn)。FixedButtressUsingflat-sidedockingduetothepipelineconnection,whenthepipelinepressureafterthepipe2,elbow,tee,adjustable,blind-sideandmanyotherplaceswillproduceunevenstress,andoffsetphenomenasuchaspipelinesoccurred,ifthesurroundingsoilpipelinecannotprovidesuffici

固化劑和促進劑直接混合會發(fā)生劇烈反應(yīng)。預(yù)防措施:操作現(xiàn)場必須配備2~3個滅火器,且操作者必須是經(jīng)過培訓(xùn)合格的。curingagentsandacceleratorsdirectmixingofviolentreaction.Preventivemeasures:operatingon-sitemustbeequippedwith2~3fireextinguishers,andtheoperatormustbetrainedqualified.3、 玻璃鋼在糊制完畢固化過程中會放熱,另外為減少濕氣,用噴燈烤干時,操作不當(dāng)也會因造成局部過熱而引發(fā)火災(zāi)。預(yù)防措施同上。glassfiberreinforcedplasticinthepastesystemwillheatthecuringprocessiscompleted,anothertoreducethemoisture,withtheblowtorch,whendried,improperoperationwillresultinlocaloverheatingcausedbyafire.PreventivemeasuresIbid.4、 糊制前的拋光打磨,會產(chǎn)生大量粉塵,該粉塵是玻璃纖維和樹脂等化工原料的混合物,接觸皮膚或吸入肺中都會對人造成傷害,甚至部分人還會產(chǎn)生過敏反應(yīng)。預(yù)防措施:采取必要的防護措施,配備保健物品及防護藥品。pre-polishingpastethesystemwillcreatealotofdust,thedust,glassfiberandresinmixtureofchemicalrawmaterialssuchascontactwithskinorinhaledinthelungwouldcauseharmtopeople,evensomepeoplealsogiverisetoallergicreactions.Preventivemeasures:totakethenecessaryprotectivemeasures,withhealthcaresuppliesandprotectivedrugs.5、 在長管線中施工,粉塵大,再加上一些揮發(fā)物質(zhì)的綜合作用,會使操作者胸悶、窒息。預(yù)防措施:管口處配備風(fēng)機(5kw以上)送風(fēng)或排風(fēng),工人操作時,連續(xù)工作時間不能超過一小時。inthelongpipelineconstruction,dust,large,plusanumberofvolatilesubstancesincombination,willmaketheoperatorchesttightness,suffocation.Preventivemeasures:controlthemouthwithafan(5kwormore)airsupp
