Chitoliro cha Spiral Welded Carbon Steels cha Machubu a Madzi

Chitoliro cha Zitsulo za Carbon Zosefedwa Zozungulira Cha Machubu a Madzi Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Kuzungulira malo ambiri ogwirira ntchito, magwiridwe antchito a madzi ndi mafakitale amadalira kwambiri kulimba ndi kugwira ntchito bwino kwa mapaipi. Pakati pa mitundu yosiyanasiyana ya mapaipi omwe amagwiritsidwa ntchito, mapaipi achitsulo cha kaboni olumikizidwa ndi spiral ayenera kuonedwa chifukwa cha mphamvu zawo zapamwamba komanso kusinthasintha kwawo. Pansipa tikuyamba kufotokoza kufunika ndi ubwino wa mapaipi achitsulo cha kaboni olumikizidwa ndi spiral mumapaipi amadzi ndi kuwotcherera mapaipi achitsulo.

1. Kumvetsetsa chitoliro chachitsulo cha kaboni cholumikizidwa mozungulira:

Chitoliro chachitsulo cha kaboni chozungulira cholumikizidwaImapangidwa mozungulira ndikuwotcherera kuchokera ku zitsulo zozungulira. Njira yapadera yopangira imapangitsa mapaipi awa kukhala olimba komanso olimba, okhoza kupirira kupsinjika kwakukulu kwamkati ndi kunja. Kuthekera kokana dzimbiri ndi kusintha kwa zinthu kumapangitsanso kuti ikhale yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo mapaipi amadzi ndi kuwotcherera mapaipi achitsulo.

2. Mapaipi olumikizira madzi:

Mu njira zogawa madzi, kupereka madzi oyera motetezeka komanso moyenera n'kofunika kwambiri. Chitoliro chachitsulo cha kaboni cholumikizidwa ndi spiral chakhala chisankho chodalirika cha mapaipi amadzi chifukwa cha mphamvu zake zosagwira dzimbiri. Malo osalala a mapaipi awa amachepetsa kukangana, kuonetsetsa kuti madzi akuyenda nthawi zonse komanso kuchepetsa kugwedezeka. Kuphatikiza apo, mphamvu ndi kulimba kwachilengedwe zimatsimikizira chitetezo ku kutuluka kwa madzi, kusweka, ndi kulephera kwa kapangidwe kake, kuonetsetsa kuti madzi akupitilizabe kukhala odalirika.

3. Kuwotcherera mapaipi achitsulo:

Makampani opanga zolumikizira amadalira kwambiri chitoliro chachitsulo cha kaboni cholumikizidwa ndi spiral welded kuti chigwiritsidwe ntchito m'njira zosiyanasiyana. Mphamvu yapadera komanso kusinthasintha kwa mapaipi awa zimapangitsa kuti akhale abwino kwambiri pakulumikiza mapaipi achitsulo. Kaya akumanga matanki akuluakulu osungiramo zinthu, mapaipi onyamulira mafuta ndi gasi, kapena zida zomangira m'mafakitale, mapaipi achitsulo cha kaboni cholumikizidwa ndi spiral welded amachita gawo lofunika kwambiri. Kufanana kwa malo olumikizirana olumikizidwa kumatsimikizira kudalirika ndi chitetezo cha kapangidwe kake, kuchepetsa kufunikira kokonza kapena kukonza pafupipafupi.

4. Ubwino ndi ubwino:

4.1 Yankho lotsika mtengo: Chitoliro chachitsulo cha kaboni cholumikizidwa mozungulira chimapereka yankho lotsika mtengo lothandizira kuwotcherera mapaipi amadzi ndi mapaipi achitsulo. Kulimba kwawo komanso kukana dzimbiri kumatsimikizira moyo wautali wa ntchito, motero kuchepetsa ndalama zosinthira ndi kukonza.

4.2 Yosavuta kuyiyika: Ukadaulo wowotcherera wozungulira womwe umagwiritsidwa ntchito popanga zinthu ungapangitse mapaipi ataliatali komanso opitilira, zomwe zimachepetsa kufunika kolumikizana pafupipafupi. Kapangidwe kameneka kamapangitsa kuti njira yoyikira ikhale yosavuta, ndikusunga nthawi ndi khama.

4.3 Kusinthasintha: Mapaipi achitsulo cha kaboni opangidwa ndi spiral welded amapezeka m'madigiri ndi makulidwe osiyanasiyana, zomwe zimathandiza kuti azitha kugwiritsidwa ntchito mosiyanasiyana. Akhoza kusinthidwa kuti akwaniritse zofunikira za polojekitiyi, malinga ndi madzi osiyanasiyana, kupanikizika, ndi kutentha.

4.4 Kuteteza chilengedwe: Chitsulo cha kaboni ndi chinthu chobwezerezedwanso chomwe chimathandiza kuti chilengedwe chikhale cholimba. Mapaipi achitsulo cha kaboni olumikizidwa mozungulira amatha kubwezerezedwanso ndikugwiritsidwanso ntchito, kuchepetsa zinyalala ndikuteteza zachilengedwe.

Pomaliza:

Mphamvu ndi ubwino wa mapaipi achitsulo cha kaboni cholumikizidwa mozungulira mu mapaipi amadzi ndikuwotcherera chitoliro chachitsuloSizingaganiziridwe kuti ndi zodalirika komanso zodalirika. Kusamutsa bwino madzi ndi madzi a m'mafakitale kumadalira kwambiri kulimba kwawo, kukana dzimbiri komanso kuyika mosavuta. Pamene kufunikira kwa zomangamanga zolimba komanso zotsika mtengo kukupitirira kukwera, mapaipi achitsulo cha kaboni olumikizidwa mozungulira adzakhalabe gawo lofunikira pakuwonetsetsa kuti machitidwe amadzi ndi mafakitale padziko lonse lapansi akugwira ntchito bwino.
