M'mimba mwake mwadzina ndi m'mimba mwake mkati ndi kunja kwa chitoliro chachitsulo chozungulira

Chitoliro chachitsulo chozungulirandi mtundu wa chitoliro chachitsulo chopangidwa mwa kukulunga chingwe chachitsulo kukhala chitoliro pa ngodya inayake yozungulira (kupangira ngodya) kenako nkuchilumikiza. Chimagwiritsidwa ntchito kwambiri m'mapayipi opangira mafuta, gasi wachilengedwe ndi madzi.

M'mimba mwake mwapadera ndi m'mimba mwake mwapadera wa chitoliro, mtengo wake wofanana ndi kukula kwa chitoliro. Pa chitoliro chachitsulo chozungulira, m'mimba mwake mwapadera nthawi zambiri umakhala pafupi, koma sufanana ndi, m'mimba mwake weniweni wamkati kapena kunja.

Kawirikawiri imafotokozedwa ndi DN kuphatikiza nambala, monga DN200, yomwe imasonyeza chitoliro chachitsulo chokhala ndi mainchesi 200 mm.

Magawo ofanana a mainchesi (DN):
1. Kukula kwa mainchesi ang'onoang'ono (DN100 - DN300):
DN100 (mainchesi 4)
DN150 (mainchesi 6)
DN200 (mainchesi 8)
DN250 (mainchesi 10)
DN300 (mainchesi 12)

2. Kukula kwapakati kwa mainchesi (DN350 - DN700):
DN350 (mainchesi 14)
DN400 (mainchesi 16)
DN450 (mainchesi 18)
DN500 (mainchesi 20)
DN600 (mainchesi 24)
DN700 (mainchesi 28)

3. Chigawo Chachikulu Cha Diameter (DN750 - DN1200)
DN750 (mainchesi 30)
DN800 (mainchesi 32)
DN900 (mainchesi 36)
DN1000 (mainchesi 40)
DN1100 (mainchesi 44)
DN1200 (mainchesi 48)

4. Kukula kwakukulu kwambiri kwa mainchesi (DN1300 ndi kupitirira apo)
DN1300 (mainchesi 52)
DN1400 (mainchesi 56)
DN1500 (mainchesi 60)
DN1600 (mainchesi 64)
DN1800 (mainchesi 72)
DN2000 (mainchesi 80)
DN2200 (mainchesi 88)
DN2400 (mainchesi 96)
DN2600 (mainchesi 104)
DN2800 (mainchesi 112)
DN3000 (mainchesi 120)

Dayamita yakunja (OD): OD ndi dayamita ya pamwamba pa chitoliro chachitsulo chozungulira. OD ya chitoliro chachitsulo chozungulira ndi kukula kwenikweni kwa kunja kwa chitoliro. OD ingapezeke poyesa kwenikweni, nthawi zambiri mu mamilimita (mm).
Chidutswa chamkati (ID): ID ndi m'mimba mwake wa pamwamba pa chitoliro chachitsulo chozungulira. ID ndi kukula kwenikweni kwa mkati mwa chitoliro. ID nthawi zambiri imawerengedwa pochotsa makulidwe a khoma kawiri kuchokera ku OD mu mamilimita (mm) ID = OD-2 x Kukhuthala kwa Khoma

Munda wofunsira

Mapaipi achitsulo ozungulira okhala ndi mainchesi osiyanasiyana amagwiritsidwa ntchito mosiyanasiyana m'magawo osiyanasiyana:
1. m'mimba mwake kakang'onoChitoliro cha Chitsulo cha Ssaw(DN100 - DN300): imagwiritsidwa ntchito kwambiri mu uinjiniya wa boma pa mapaipi operekera madzi, mapaipi otulutsira madzi, mapaipi a gasi, ndi zina zotero.
2. m'mimba mwake wapakatiChitoliro cha Ssaw(DN350 - DN700): imagwiritsidwa ntchito kwambiri mu mapaipi amafuta, gasi lachilengedwe ndi mapaipi amadzi a mafakitale. 3. chitoliro chachikulu chachitsulo chozungulira (DN100 - DN300): chomwe chimagwiritsidwa ntchito kwambiri mu mapaipi operekera madzi aukadaulo wa boma, mapaipi otulutsa madzi, mapaipi a gasi, ndi zina zotero.
3.Chitoliro chachikulu cha Ssaw m'mimba mwake(DN750 - DN1200): imagwiritsidwa ntchito m'mapulojekiti otumizira madzi akutali, mapaipi amafuta, mapulojekiti akuluakulu amafakitale, monga mayendedwe apakati.
4. m'mimba mwake waukulu kwambiriChitoliro cha Ssaw Carbon Steel(DN1300 ndi kupitirira apo): imagwiritsidwa ntchito makamaka pa ntchito za mapaipi amadzi, mafuta ndi gasi oyenda mtunda wautali m'madera osiyanasiyana, mapaipi a pansi pamadzi ndi mapulojekiti ena akuluakulu omanga nyumba.

M'mimba mwake mwapadera ndi zina zomwe zimagwiritsidwa ntchito popangira chitoliro chachitsulo chozungulira nthawi zambiri zimapangidwa motsatira miyezo ndi mafotokozedwe oyenera:
1. miyezo yapadziko lonse lapansi: API 5L: yogwiritsidwa ntchito pa chitoliro chachitsulo choyendera mapaipi, imatchula kukula ndi zofunikira za chitoliro chachitsulo chozungulira ASTM A252: yogwiritsidwa ntchito pa chitoliro chachitsulo chozungulira, imatchula kukula ndi zofunikira zopangira chitoliro chachitsulo chozungulira.
2. muyezo wa dziko: GB/T 9711: yogwiritsidwa ntchito pa chitoliro chachitsulo poyendetsa mafuta ndi gasi, imafotokoza zofunikira zaukadaulo za chitoliro chachitsulo chozungulira. gb/t 3091: yogwiritsidwa ntchito pa chitoliro chachitsulo chosungunuka poyendetsa madzi otsika, imafotokoza kukula ndi zofunikira zaukadaulo za chitoliro chachitsulo chozungulira.
