1.Conditions ndi Kukonzekera Kuyesa Kupanikizika
1.1 Ntchito yomanga mapaipi yatsirizidwa, ndipo ikugwirizana ndi zofunikira ndi ndondomeko.
1.2 Ntchito yowotcherera imatsirizidwa pambuyo poti choyikapo chosakaniza ndi choyikapo chitoliro chayikidwa.Kuzindikira kwa ray kwafika kwathunthu pamapangidwewo ndikudutsa kuyendera.Ma welds ndi malo ena owunikira omwe akuyenera kuyesedwa samapakidwa utoto komanso kutsekeredwa.
1.3Kuyeza kuthamanga kwa mayeso kwatsimikiziridwa, ndipo kulondola ndi milingo 1.5.Mtengo wathunthu wa tebulo uyenera kukhala 1.5 mpaka 2 nthawi yoyezera mpaka kuthamanga kwambiri.
1.4 Mayeso asanachitike, simungatenge nawo gawo pamayeso, zida ndi zida, ndikuwonjezera utoto woyera wokhala ndi pepala loyera lokhala ndi mbale yakhungu.
1.5 Madzi ayenera kugwiritsidwa ntchito poyeretsa madzi, ndipo chloride yomwe ili m'madzi sayenera kupitirira 25 × 10-6 (25ppm).
1.6 Kulimbitsa mapaipi kwakanthawi pamayesero kuyenera kutsimikiziridwa ndi kudalirika pambuyo poyang'aniridwa.
1.7Yang'anani ngati mavavu onse papaipi ali otsegula, ngati mapepala awonjezedwa, ndipo imitsani pakati pa valavu ya valavu, ndiyeno yambitsaninso mpaka iphulitsidwe.
2.Process Pipeline Test Pressure Process
2.1.Kuthamanga kwa mayeso a mapaipi ndi 1.5 kuwirikiza kamangidwe kake.
2.2.Pamene payipi ndi zipangizo zimayesedwa ngati dongosolo, kupanikizika kwa payipi kumakhala kofanana kapena kucheperapo kusiyana ndi kuyesa kwa chipangizocho.Essence
2.3.Pamene jekeseni wa madzi a dongosolo, mpweya uyenera kutha.Malo otulutsa mpweya ayenera kukhala pamwamba pa payipi ndikuwonjezera valavu yotulutsa mpweya.
2.4.Mapaipi okhala ndi malo akulu ayenera kuyeza kukakamiza koyeserera kwa sing'anga yoyesera.Kuyesedwa kwa payipi yamadzimadzi kuyenera kutengera kuthamanga kwapamwamba kwambiri, koma malo otsika kwambiri a malo ocheperako sayenera kupitilira kulolerana kwa mapaipi.
2.5.Pamene mayeso kuthamanga, mphamvu kuyenera kuchitidwa pang'onopang'ono.Pambuyo pa kukakamizidwa kwa mayeso, kuthamanga kwapakati kuyenera kukhala mphindi 10.Popanda kutayikira, palibe mapindikidwe omwe ali oyenerera, ndiyeno kukakamizidwa kwa mayeso kumachepetsedwa mpaka kukakamiza kwa mapangidwe.Essence
2.6.Pambuyo poyesa, mbale yakhungu iyenera kuchotsedwa nthawi kuti iwononge madzi.Panthawi yothira madzi, kuthamanga koyipa kuyenera kupewedwa, ndipo palibe ngalande yomwe ingatsanulidwe kulikonse.Pamene kutayikira kumapezeka panthawi yoyesera, sikuloledwa kuthandizidwa ndi kukakamizidwa.Pambuyo pochotsa zolakwikazo, mayesowo amayenera kuyesedwanso.
2.7.Kuyesedwa kwa kutayikira kunachitika pambuyo poti kuyezetsa kukakamizidwa kunali koyenerera, ndipo sing'anga yoyesera idapanikizidwa ndi mpweya woponderezedwa.
2.8.Kupanikizika kwa mayeso othamanga ndiko kukakamiza kwa mapangidwe.Mayeso a kutayikira ayenera kuyang'ana pakuyang'ana kalata yodzaza.Flange kapena ulusi umalumikizidwa ndi valavu yopanda kanthu, valavu yotulutsa mpweya, ndi valavu yotulutsa madzi.
3. Lunga mapaipi kuwomba ndi kuyeretsa
3.1.Zofunikira zaukadaulo
3.1.1 Njira yopangira mapaipi iyenera kuwombedwa ndikutsukidwa m'zigawo (zotchedwa kuwomba).
3.1.2 Njira yowombera imatsimikiziridwa malinga ndi zofunikira za payipi, sing'anga yogwirira ntchito, ndi dothi pamwamba pa payipi.Mayendedwe a kuwomba nthawi zambiri amachitika motsatira dongosolo la oyang'anira, othandizira, ndi mapaipi otulutsa.
3.1.3 Musanayambe kuwomba, chida chomwe chili mu dongosololi chiyenera kutetezedwa, ndipo bolodi la pore, valavu yoyendetsa fyuluta ndi valavu yoyimitsa iyenera kugwetsedwa, ndipo imasungidwa bwino.
3.1.4 Pakuwomba, ma ducts sayenera kulowa mu chipangizocho, ndipo ziwalo zomwe zimatulutsa zida siziyenera kulowa mupaipi.
3.1.5 Zida ndi mapaipi omwe saloledwa kutsukidwa azisiyanitsidwa ndi makina owombera.
3.1.6 Kuwomba kwa mapaipi kuyenera kukhala ndi mpweya wokwanira.Kuthamanga kwa kuwomba sikuyenera kupitirira mphamvu ya mapangidwe.Kuthamanga nthawi zambiri sikuchepera 20m / s.Powomba, gwiritsani ntchito nyundo yamatabwa kugogoda chubu.Osawononga chubu.
3.1.7 Ganizirani za kulimba kwa nthambi ya mapaipi ndi choyikapo chopachika musanawombe, ndipo kulimbikitsanso kuyenera kuperekedwa ngati kuli kofunikira.
3.2.Kuwomba mapaipi, njira yoyeretsera
3.2.1 Kutaya madzi: Njira yogwirira ntchito ndi payipi yamadzi.Kutsuka kwamadzi kumatha kufika pamtunda wothamanga kwambiri kapena osachepera 1.5m/s mu chitoliro.Mtundu wa madzi otumiza kunja ndi kuwonekera zimagwirizana ndi kuyang'ana kowonekera pakhomo.Pambuyo pa payipi yoyenerera, madzi ayenera kutha panthawi.
3.2.2 Kuwombera mpweya: Sing'anga yogwirira ntchito ndi payipi ya gasi.Aliyense amene akumana ndi valavu ayenera kumasula flange yam'mbuyo ndikuwonjezera baffle, ndiyeno kukonzanso payipi ikawomberedwa.Kupanikizika sikuyenera kupitirira mphamvu ya mapangidwe a chidebe ndi payipi, ndipo kuthamanga kwake sikuyenera kukhala kosachepera 20m / s.Pamene mpweya kuwomba ndondomeko, pamene zowoneka utsi utsi ndi fumbi, matabwa chandamale bolodi anayendera utoto woyera amaikidwa pa doko utsi, ndipo palibe dzimbiri, fumbi, chinyezi ndi zinyalala pa chandamale bolodi 5 mphindi.
3.2.3 Kuwomba nthunzi: Malo ogwirira ntchito amawunikiridwa ndi mapaipi a nthunzi ya mapaipi a nthunzi.Nthunzi isanayambe kuwomba, chubu lofunda liyenera kukwezedwa pang'onopang'ono kuti liwombe, kenako limazizira ku kutentha kwa chilengedwe.Pakamwa pa malo otulutsa mpweya wa nthunzi imapendekeka m'mwamba, ndipo chizindikirocho chimakopa maso.The awiri a chitoliro utsi sikuyenera kukhala laling'ono kuposa awiri a chitoliro kuwomba.Miyezo yoyenelela: sinthani bolodi yomwe mukufuna kutsata kawiri motsatizana.Pansi pa ziyeneretso zonse), ndi chiyeneretso cha scanning.
3.2.4 Kubwezeretsanso mapaipi: Pambuyo poyezetsa mapaipi ndi kuwomba ndikuyenerera, bolodi lakhungu liyenera kuchotsedwa panthawi yake molingana ndi zolemba, ndi valavu yoyang'anira, kuyimitsa chigawo cha valve, chida cha chida.
