Kukula kwa mapaipi a gasi kumatha kukhala mainchesi 2 mpaka 60 pomwe mapaipi amafuta amachokera ku mainchesi 4 mpaka 48 mkati kutengera kufunikira.Njira yopangira mafutazitha kupangidwa ndi chitsulo kapena pulasitiki koma chogwiritsidwa ntchito kwambiri ndi chitoliro chachitsulo.Mapaipi achitsulo osungunula amatenthedwa amagwiritsidwa ntchito kwambiri potengera mafuta ndi gasi.

Ubwino wa mapaipi achitsulo:
Mapaipi achitsulo omwe akhala akukwiriridwa kwazaka mazana ambiri ali ndi zinthu zodabwitsa kuphatikiza kupsinjika kwamphamvu kukana gasi.Zili zodetsedwa ndipo zimakhala ndi mphamvu zolimbana nazo kwambiri, zimakonda kwambiri HDB pa 20°C, 60°C ndi 80°C, kutsika kochepa kwa methane ndi haidrojeni.Ili ndi magwiridwe antchito odalirika a UV posungira kunja.Zomwe zimapangidwira zimakhala ndi thovu la polyurethane (PU) lomwe limakhala ndi kutentha kwambiri komanso limakhala lamphamvu pamakina.

Mapaipi abwino kwambiri amafuta ndi gasi:
Mipope yachitsulo yaying'ono, yapakatikati ndi yayikulu imapezeka komabe, mphamvu yayikulu yachitsulo imapangitsa kupindika ndikupanga kukhala kovuta kwambiri.Nthawi zambiri, Electric Resistance Welded (RW) chitoliro chachitsulo chimagwiritsidwa ntchito pokonza mafuta ndi gasi ndi mizere yotumizira yomwe imatsimikizira kuti imagwira ntchito bwino.Mapaipi a ERW ndi abwinonso m'malo otentha kapena onyowa monga kuwoloka mitsinje ndi malo ovuta.

Kufunika kwadongosolo kwa kayendedwe ka mafuta ndi gasi ndi kugawa kwa magetsi kwatsindika kupanga mapaipi azitsulo ndi machubu.Kutsimikizira dzimbiri, utoto wotengera madzi umayikidwa papaipi yakunja kuti atetezere ku dzimbiri mumlengalenga panthawi yoyendetsa ndi kusungirako ndipo zokutira zoteteza za PE za 3-wosanjikiza zitha kugwiritsidwa ntchito pamapaipi popempha Makasitomala.

Mipope yachitsulo ndi mapaipi amtunda wautali amadzimadzi oyaka ndi mpweya.Mapaipi opanda msoko omwe amagwiritsidwa ntchito popanga mapaipi amtunda wautali amadzimadzi ndi mpweya woyaka, mapaipi a siteshoni ya nyukiliya, mapaipi otenthetsera, mapaipi acholinga chambiri.Chifukwa chake, zofunika zolimba zamachubu azitsulo zamzere ndizovuta kwambiri kuposa zomwe zimafunikira katundu.

Mipope yachitsulo ya mzere imapangidwa ndi kusungunuka mu ng'anjo yamagetsi, yopangidwa ndi slags yopangidwa ndi kuponyedwa ndi ma casters mosalekeza.Kupanga zitsulo zogwiritsidwa ntchito kumatsimikizira kukwaniritsidwa kwa chitsulo choyera chamankhwala ponena za sulfure ndi phosphor zomwe zimapatsa mphamvu zolimba, ductility ndi dzimbiri kukana kwa mapaipi kuti azigwiritsidwa ntchito pazitentha zotsika pama media osiyanasiyana owononga.

Mapaipi achitsulo opangidwa ndi thermally ndi ofunika kwambiri pamakampani amafuta ndi gasi.Mapaipi achitsulo, omwe aikidwa m'manda kwazaka mazana ambiri, ali ndi zinthu zodabwitsa kuphatikiza kukana kupsinjika kwa gasi wachilengedwe ndi zowononga zake, kutsika kochepa kwa methane ndi haidrojeni, kuchuluka kwa HDB pa 20 ° C, 60 ° C ndi 80 ° C, kupitilira apo. kukana mphamvu, kufinya, ndi magwiridwe antchito odalirika a UV posungira kunja.Zomwe zimapangidwira zimakhala ndi thovu la polyurethane (PU), lomwe limakhala ndi kutentha kwambiri komanso limakhala lamphamvu pamakina.

Mapaipi ang'onoang'ono, apakatikati ndi akulu apakati amapezeka ndipo mphamvu yayikulu yachitsulo imapangitsanso kupindana ndikupanga kukhala kovuta kwambiri.Nthawi zambiri, Electric Resistance Welded (RW) Pipe yachitsulo imagwiritsidwa ntchito pokonza mafuta ndi gasi ndi mizere yotumizira yolembetsedwa ndikutsimikizira kukhazikika kwake pamagwiritsidwe ake.Mapaipi amafuta ndi gasi awa ndi abwinonso m'malo otentha kapena onyowa monga kuwoloka mitsinje ndi malo ovuta.Kugwiritsa ntchito chitsulo kumapereka muyezo wa chitoliro choyenera kugwiritsidwa ntchito potumiza gasi, madzi ndi mafuta m'mafakitale amafuta ndi gasi.
