SAWH Comprehensive Guide to Tube: A252 Giredi 1 Pipe yachitsulo ya Mafuta ndi Mafuta Ogwiritsa Ntchito Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

SAWH (Submerged Arc Welded Spiral) chitoliro chimagwiritsidwa ntchito kwambiri m'makampani amafuta ndi gasi chifukwa champhamvu zake komanso kulimba kwake.Mu blog iyi, tiwona mbali zazikulu ndi zabwino zakeA252 Gulu 1 chitoliro chachitsulo amagwiritsidwa ntchito kwambiri popaka mafuta ndi gasi.Pomaliza, mumvetsetsa bwino mapaipi a SAWH komanso kufunikira kwawo pamsika.

1. Kumvetsetsa payipi ya SAWH:

Zithunzi za SAWHamapangidwa kuchokera ku mbale zachitsulo zokonzedwa mozungulira.Mapepalawa amapangidwa kukhala machubu ndi kuwotcherera pogwiritsa ntchito kulowetsedwa kwa arc kuwotcherera.Njira yowotcherera iyi imatsimikizira kuwotcherera kwamphamvu, kosalekeza pamtunda wonse wa chitoliro, ndikupangitsa kuti ikhale yolimbana ndi zovuta zakunja monga momwe zimakhudzira komanso kupanikizika.Mapaipiwa amadziwika chifukwa cha mphamvu zake zonyamula katundu komanso kusamalidwa bwino, zomwe zimawapangitsa kukhala abwino kunyamula mafuta ndi gasi.

2. A252 giredi 1 chitoliro chachitsulo:

A252 GRADE 1 ndi ndondomeko ya chitoliro chachitsulo chopangidwira makamaka kuti chigwiritse ntchito zokakamiza.Mapaipiwa amapangidwa kuchokera ku chitsulo cha A252, chomwe chili ndi zida zamakina abwino kwambiri komanso mphamvu zolimba kwambiri.Chitoliro chachitsulo cha A252 GRADE 1 chimagwiritsidwa ntchito kwambiri chifukwa chotha kupirira kupsinjika kwakukulu ndikukana dzimbiri ndi mapindikidwe m'malo ovuta amafuta ndi gasi.

3. Ubwino wa chitoliro chachitsulo cha A252 giredi 1:

a) Mphamvu ndi Kukhalitsa:A252 giredi 1 chitoliro chachitsulondi yamphamvu komanso yolimba, imatha kupirira katundu wolemetsa ndipo ndi yoyenera pamakina otumizira mafuta ndi gasi.Mphamvu zawo zolimba kwambiri zimatsimikizira kukhazikika kwa nthawi yayitali ndikuchepetsa zofunikira zosamalira.

b) Kulimbana ndi dzimbiri: Mapaipi amafuta ndi gasi amakonda kuchita dzimbiri chifukwa cha zovuta zachilengedwe.Chitoliro chachitsulo cha A252 GRADE 1 chimakhala ndi zokutira zina zosagwirizana ndi dzimbiri, monga epoxy (FBE), kuti zilimbikitse kulimba kwake ndikuwonjezera moyo wake wantchito.

c) Kusinthasintha: Mapaipi a SAWH amatha kupangidwa mosiyanasiyana ndi kutalika kwake kuti akwaniritse zofunikira za polojekiti.Kusinthasintha uku kumathandizira kukhazikitsa popanda kufunikira kolumikizirana angapo, kuchepetsa chiopsezo cha kutayikira.

d) Zotsika mtengo: Chitoliro chachitsulo cha A252 Grade 1 chimapereka njira yotsika mtengo yamapaipi amafuta ndi gasi.Moyo wawo wautali wautumiki komanso zofunikira zochepa zosamalira zimachepetsa ndalama zogwirira ntchito pakapita nthawi.

4. Kugwiritsa ntchito chitoliro chachitsulo cha A252 giredi 1:

Chitoliro chachitsulo cha A252 Grade 1 chili ndi ntchito zosiyanasiyana pamakampani amafuta ndi gasi, kuphatikiza:

a) Mapaipi otumizira: amagwiritsidwa ntchito kunyamula mafuta osapsa, gasi ndi zinthu zina zamafuta kuchokera kumalo opangirako kupita kumalo oyeretsera ndi kugawa.

b) Kubowola Kunyanja: Mapaipi a SAWH amagwiritsidwa ntchito pobowola mafuta akunyanja ndi gasi.Kukana kwawo kwa dzimbiri komanso kuthamanga kwamphamvu kumawapangitsa kukhala oyenera kufufuza m'nyanja yakuya.

c) Kuyenga: Mapaipi achitsulo a A252 GRADE 1 amagwiritsidwa ntchito kwambiri m'malo oyeretsera kuti azitha kunyamula mafuta osakanizidwa ndi zinthu zamafuta.

Pomaliza:

Mapaipi a SAWH, makamaka mapaipi achitsulo a A252 GRADE 1, amagwira ntchito yofunika kwambiri pakupangachitoliro cha mafuta ndi gasimakampani.Mphamvu zawo, kulimba kwawo, komanso kukana kwa dzimbiri zimawapangitsa kukhala odalirika pazogwiritsa ntchito zosiyanasiyana.Kumvetsetsa ubwino wa mapaipi a SAWH ndi mawonekedwe ake enieni kungathandize kuonetsetsa kuti mafuta ndi gasi akuyenda bwino komanso kuchepetsa mtengo wokonza ndikuwonjezera ntchito yabwino.
