Mainchesi mulifupi ndi mkati ndi kunja kwa chitoliro cha stal

Chitoliro chachitsulondi mtundu wa chitoliro chachitsulo chopangidwa ndikugudubuza chipilala chachitsulo kukhala chitoliro chowoneka bwino pamtunda wina (kupanga ngodya) kenako kuwaza. Amagwiritsidwa ntchito kwambiri m'mapaipi a mapaipi a mafuta, mpweya wachilengedwe ndi kufalikira kwamadzi.

Diamil mulifupimu ndi mainchesi osadziwika a chitoliro, mtengo wa mwadzina wa kukula kwa chitoliro. Kwa chitoliro cha staff stal, mainloni mwadzina nthawi zambiri amakhala pafupi, koma osati ofanana, enieni mkati kapena kunja.

Nthawi zambiri zimafotokozedwa ndi DN kuphatikiza manambala, monga DN200, yomwe ikuwonetsa chitoliro chachitsulo chokhala ndi mainchesi a 200 mm.

Kufala kwa Nomwel (DN) Kusiyanasiyana:
1. Mitundu yaying'ono ya diameter (DN100 - DN300):
DN100 (mainchesi 4)
DN150 (mainchesi 6)
DN200 (mainchesi 8)
DN250 (mainchesi 10)
DN300 (mainchesi 12)

2. Mitundu ina yapakatikati (DN350 - DN700):
DN350 (14 mainchesi)
DN400 (mainchesi 16)
DN450 (18 mainchesi)
DN500 (mainchesi 20)
DN600 (mainchesi 24)
DN700 (mainchesi 28)

3. Mitundu ikuluikulu kwambiri (DN750 - DN1200)
DN750 (mainchesi 30)
DN800 (mainchesi 32)
DN900 (mainchesi 36)
DN1000 (mainchesi 40)
DN1100 (mainchesi 44)
DN1200 (mainchesi 48)

DN2000 (mainchesi 80)
DN2200 (mainchesi 88)
DN2400 (mainchesi 96)
DN2600 (mainchesi 104)
DN2800 (mainchesi 112)
DN3000 (mainchesi 120)

Diameter yakumanja (OD): OD ndi mainchesi akunja a chitoliro cha sporsing. Chitoliro cha staff chitoliro ndicho kukula kwenikweni kwa chitoliro cha chitoliro. Od od amatha kupezeka ndi muyeso weniweni, nthawi zambiri amakhala m'mamilimeter (mm).
Madera amkati (ID): ID ndi mainchesi amkati mwa chitoliro cha sporch. ID ndi kukula kwenikweni kwa mkati mwa chitoliro. ID imawerengedwa ndi kuchotsera kawiri pakhoma makulidwe kuchokera ku mamilimita (mm) ID = 2 x khoma makulidwe

Gawo la ntchito

Mapaipi achitsulo okhala ndi ma diameter osiyanasiyana a nomwel ali ndi mapulogalamu osiyanasiyana m'minda yosiyanasiyana:
1. Diamenti yaying'onoChitoliro cha SSAW.
2. Mulingo wapakatiChitoliro cha SSAW. 3..
3.Chitoliro chachikulu cha SSAW SSAW.
4. Ultra-InternerSsaw Carbon Shael.

Mawonekedwe a nomwel ndi mitundu ina ya chitoliro cha stal nthawi zambiri chimapangidwa mogwirizana ndi miyezo yoyenera:
1. Makhalidwe apadziko lonse lapansi: API 5l: Kugwiritsa Ntchito Mapaipi A Speil, kumafotokoza kukula ndi zofunikira pa chitoliro cha spil astm A252: Kugwiritsa ntchito chitoliro chachitsulo, chimafotokoza zopanga zitoliro za spil.
2. National Standard: GB / T 9711: Kugwiritsa ntchito chitoliro chachitsulo cha makilogalamu a mafuta ndi gasi, amafotokoza zofunikira za chitoliro cha spil. GB / T 3091: Kugwira ntchito pa chitoliro chachitsulo choyendera madzi otsika, amafotokoza kukula ndi zofunikira zaukadaulo.
