Cholinga cha Zithunzi
Kukuta mapaipi achitsulo ndikofunikira kuti muchepetse dzimbiri. Kuphukira pamiyala yachitsulo kumatha kukhudza magwiridwe awo, abwino komanso owoneka. Chifukwa chake, zokutira zimakhudza kwambiri mtundu wonse wa zinthu zachitsulo.

Zofunikira pakupanga zidutswa
Malinga ndi miyezo yokhazikitsidwa ndi American Petroleum Institute, mapaipi achitsulo akuyenera kukana kuwonongera kwa miyezi itatu. Komabe, kufunikira kwa nthawi yayitali kwa nthawi yayitali kwachuluka, omwe amagwiritsa ntchito ambiri amafuna kukana kwa miyezi itatu mpaka 6 ku malo osungira kunja. Kupatula kungokhala ndi moyo wosangalatsa, ogwiritsa ntchito amayembekeza kuti akuphatikiza bwino kuti azikhala osalala, ngakhale kugawidwa kwa anti-onti-milomo popanda kudumpha kapena kutsika komwe kungakhudze mawonekedwe.

Mitundu ya zokutira ndi zabwino zawo ndi zowawa
M'matawuni pansi paumba,mapaipi achitsuloamagwiritsidwa ntchito ponyamula mpweya, mafuta, madzi, ndi zina zambiri. Zovala za zipatuzi izi zasintha chifukwa cha zikhalidwe za phula ku polsothylene remin ndi zinthu za epoxy. Kugwiritsa ntchito zokutira za polyethylene kuyamba m'ma 1980s, ndipo pogwiritsa ntchito njira zosiyanasiyana, zigawozo ndi njira zolumikizira zawona bwino pang'onopang'ono.
3.1 ma petroleum phula
Petroleums phulati, wotsutsa-conterser wosanjikiza, umakhala ndi nsalu ya petroleum, yolimbikitsidwa ndi nsalu ya fiberglass komanso yoteteza polyvinyl chloride chloride. Zimapereka zomatira zabwino kwambiri zam'mimba, zomata zosiyanasiyana, komanso kugwira ntchito modula. Komabe, ili ndi zovuta zina kuphatikizapo kutentha kutentha, kukhala bwindira mu kutentha kochepa, komanso kukhala kovuta kwambiri, makamaka m'miyeso yamiyala, makamaka yothandizanso yoteteza komanso ndalama zambiri.
3.2 Box Bor epoxy yophimba
Epoxy malailoy, opangidwa kuchokera ku epoxy utoto ndi malasha a phula, amawonetsa madzi abwino ndi kukana kwa mankhwala, mphamvu zabwino, ndi mphamvu zabwino, komanso mphamvu zabwino. Komabe, pamafunika kugwiritsa ntchito nthawi yayitali yothira ntchito, kupangitsa kuti ikhale yovuta ndi nyengo yovuta kuyambira nyengo panthawiyi. Kuphatikiza apo, madera osiyanasiyana omwe amagwiritsidwa ntchito mu njira yolumikizirayi amafunikira malo apadera osungira, kukweza ndalama.
3.3 epoxy ufa wokutidwa
Epoxy ufa wokutira, woyambitsidwa mu 1960s, umaphatikizapo kutulutsa ma eleransitic ufa ophatikizidwa ndi mawonekedwe otenthetsedwa nawo, ndikupanga osanjikiza pang'ono. Ubwino wake umaphatikizapo kutentha kwakukulu (-60 ° C mpaka 100 ° C), kutsatira kwamphamvu, kukana kwabwino ku Catodic kudandaula, kukhudzidwa, kusinthasintha, ndikuwonongeka. Komabe, kanema wake wocheperako amapangitsa kuti ziwonongeke komanso kugwiritsa ntchito njira zopangira ndi zida zopangira, poyambitsa zovuta pankhani yamunda. Ngakhale zili bwino mbali zambiri, zimaperewera poyerekeza ndi polyethylene pokana kutentha komanso kutetezedwa.
3.4 Polyethylene Anti-Corrosesve
Polyethylene imapereka mphamvu bwino kwambiri komanso kuuma kwambiri komanso kutentha kwa kutentha. Imakhala ikugwiritsa ntchito kwambiri m'magawo ozizira ngati Russia ndi Western Europe kwa ma piipelines chifukwa cha kusinthasintha kwake kotheratu, makamaka kutentha kochepa. Komabe, zovuta zimakhalabe mu ntchito yake pamapaipi akuluakulu, pomwe kupanikizika kumatha kuchitika, ndipo kulumikizana kwamadzi kumatha kuwononga pansi pa zokutira, ndikusinthanso kafukufuku wina ndi njira zakuthupi ndi zothandizira.
3.5 Kutulutsa kovomerezeka
Zovala zamphamvu zonyansa zimapereka mphamvu yolimba kwambiri poyerekeza ndi zokutira. Amawonetsa kugwira ntchito kwanthawi yayitali ngakhale atakhala zaka zowopsa, kwa zaka 10 mpaka 15 mu mankhwala, marine, ndi zosungunulira, ndi zaka zopitilira 5 mu acidic, alkaline, mikhalidwe. Zovala izi zimakhala ndi zouma za filimu kuyambira 200μm mpaka 2000μm, ndikuwonetsetsa kuti ndi kukhazikika kwambiri. Amagwiritsidwa ntchito kwambiri m'magulu am'mimba, zida zamankhwala, akasinja osungira, ndi mapaipi.

Nkhani Zofala Ndi Zithunzi Zophatikiza
Nkhani zofananira ndi zokutira zimaphatikizapo kugwiritsa ntchito ntchito yosasinthika, kudzutsa kwa othandizira odana ndi zotupa, komanso mapangidwe a thovu.

Kusanthula kwa zokutira zovuta
Vuto lililonse limatuluka pamilandu yosiyanasiyana, chifukwa cha zinthu zosiyanasiyana; Ndipo mtolo wa chitoliro chachitsulo chofotokozedwa bwino ndi mtundu wa vutoli atha kukhala kuphatikiza zingapo. Zomwe zimayambitsa kuti ndizosagwirizana ndi mitundu iwiri, imodzi ndiyonso yopanda kanthu chifukwa cha kupopera mbewu kupukuta pambuyo pa chitoliro chachitsulo kulowa m'bokosi lokutira; Chachiwiri ndi chopanda kanthu choyambitsidwa ndi kupopera mbewu mankhwalawa.
Chomwecho choyambirira ndi chosavuta kuwona, ku zida zokutira ngati chitsulo cham'manja mu bokosi la 360 ° mozungulira (mzere wamtunduwu uli ndi mfuti 12). Ngati mfuti iliyonse yophulika mu kukula kwake ndi yosiyana, ndiye kuti imatsogolera kugawa kwa anticoroferosive mu malo osiyanasiyana a chitoliro chachitsulo.
Chifukwa chachiwiri ndikuti pali zifukwa zina zosinthira chodabwitsa chopanda tanthauzo kuphatikiza kupopera mbewu mankhwalawa. Pali mitundu yambiri ya zinthu, monga chitoliro chachitsulo chobwera chomwe chikubwera, kuvutikira, kuti zokuti zigawezo ndizovuta kugawidwa moyenera; Chitoliro chachitsulo chimakhala ndi mphamvu yamadzi omwe atsalira pomwe emulsion, nthawi ino yolumikizirana ndi emulsion
. Gawo la chitoliro la chitsulo ndi chozungulira, nthawi iliyonse wothandizirana ndi wachitsulo atathiridwa pansi pa chipilala cha ziphuphu, chomwe chingachitike m'munsi mwa chinthu chotsika, chomwe chingapangitse chodabwitsa cha dontho lopachika. Chinthu chabwino ndikuti pali zida za ndulu zopanga zitsulo za chitsulo, zomwe zimathetsa kutentha ndi kulimbitsa okana kuthira pachipata chachitsulo nthawi ndikuchepetsa madzi anzeru anticrophic. Komabe, ngati mamasukidwe a wotsutsa anticrophive siwokwera; osaphika pa nthawi yomwe kupopera mbewu; kapena kutentha kutentha sikokwezeka; The szzy siyogwira ntchito bwino, etc. idzatsogolera ku AntiCorrosed Onterning madontho.
(2) Zoyambitsa zoyipa zonyansa. Chifukwa cha malo ogwiritsira ntchito chinyezi cha mpweya, kubadwa kwa utoto ndi chochulukirapo, kubalalitsa mayendedwe otenthetsera kutentha kumayambitsa chindapusa. Chuma chinyezi cha mpweya, kutentha kotsika, oteteza zikwapulidwe kuchokera kubadwa m'matomu ang'onoang'ono, kudzatsogolera kutsika. Madzi mlengalenga wokhala ndi chinyezi chambiri pambuyo pa kutentha kwa dontho kumafooketse mabulosi abwino osakanikirana, ndipo pamapeto pake amalowa mkati mwa chimbudzi, zomwe zimapangitsa kuti muyambe kuzimbira.
