Mwadzina m'mimba mwake ndi mkati ndi kunja awiri a mulingo zitsulo chitoliro

Spiral steel pipendi mtundu wa chitoliro chachitsulo chopangidwa mwa kugubuduza chingwe chachitsulo kukhala mawonekedwe a chitoliro pa ngodya inayake yozungulira (kupanga ngodya) ndiyeno kuwotcherera. Amagwiritsidwa ntchito kwambiri m'mapaipi amafuta, gasi komanso kufalitsa madzi.

M'mimba mwake mwadzina ndi m'mimba mwake mwadzina wa chitoliro, mtengo wadzina wa kukula kwa chitoliro. Kwa ozungulira zitsulo chitoliro, m'mimba mwake mwadzina nthawi zambiri pafupi, koma osati wofanana, mkati kwenikweni kapena kunja awiri.

Nthawi zambiri amawonetsedwa ndi DN kuphatikiza nambala, monga DN200, yomwe imawonetsa chitoliro chachitsulo chokhala ndi mainchesi 200 mm.

Mtundu wamba wamba (DN):
1. Mtundu waung'ono (DN100 - DN300):
DN100 (4 mainchesi)
DN150 (6 mainchesi)
DN200 (8 mainchesi)
DN250 (10 mainchesi)
DN300 (12 mainchesi)

2. Wapakati awiri osiyanasiyana (DN350 - DN700):
DN350 (14 mainchesi)
DN400 (16 mainchesi)
DN450 (18 mainchesi)
DN500 (20 mainchesi)
DN600 (24 mainchesi)
DN700 (28 mainchesi)

3. Large Diameter Range (DN750 - DN1200)
DN750 (30 mainchesi)

DN1200 (48 mainchesi)

4. Owonjezera lalikulu m'mimba mwake osiyanasiyana (DN1300 ndi pamwamba)
DN1300 (52 mainchesi)
DN1400 (56 mainchesi)
DN1500 (60 mainchesi)
DN1600 (64 mainchesi)
DN1800 (72 mainchesi)
DN2000 (80 mainchesi)
DN2200 (88 mainchesi)
DN2400 (96 mainchesi)
DN2600 (104 mainchesi)
DN2800 (112 mainchesi)
DN3000 (120 mainchesi)

M'mimba mwake (OD): OD ndi mainchesi akunja kwa chitoliro chachitsulo chozungulira. OD ya chitoliro chachitsulo chozungulira ndi kukula kwenikweni kwa kunja kwa chitoliro. OD ikhoza kupezedwa ndi kuyeza kwenikweni, nthawi zambiri mu millimeters (mm).
Diameter Yam'kati (ID): ID ndi mainchesi amkati mwa chitoliro chachitsulo chozungulira. ID ndi kukula kwenikweni kwa mkati mwa chitoliro. ID nthawi zambiri imawerengedwa pochotsa makulidwe a khoma kuchokera ku OD mu millimeters (mm) ID = OD-2 x Makulidwe a Khoma.

Malo ogwiritsira ntchito

Mapaipi achitsulo ozungulira okhala ndi mainchesi osiyanasiyana amafanana ndi ntchito zosiyanasiyana m'magawo osiyanasiyana:
1. awiri ochepaChitoliro chachitsulo cha Ssaw(DN100 - DN300): ambiri ntchito mu zomangamanga tauni kwa mipope madzi, mipope ngalande, mapaipi mpweya, etc.
2. m'mimba mwakeMsuzi Pipe(DN350 - DN700): chimagwiritsidwa ntchito mafuta, gasi payipi ndi payipi madzi mafakitale. 3. lalikulu m'mimba mwake ozungulira zitsulo chitoliro (DN100 - DN300): ambiri ntchito mutauni engineering payipi madzi, ngalande, payipi mpweya, etc.
3.Chitoliro Chachikulu Chachikulu cha Saw(DN750 - DN1200): amagwiritsidwa ntchito m'ma projekiti otumizira madzi mtunda wautali, mapaipi amafuta, ntchito zazikulu zama mafakitale, monga mayendedwe apakatikati.
4. M'mimba mwake kwambiriChitoliro cha Chitsulo cha Carbon(DN1300 ndi pamwambapa): amagwiritsidwa ntchito makamaka pama projekiti am'madera akutali amadzi, mafuta ndi gasi, mapaipi apansi pamadzi ndi ntchito zina zazikuluzikulu za zomangamanga.

M'mimba mwake mwadzina ndi zina za chitoliro cha chitsulo chozungulira nthawi zambiri amapangidwa molingana ndi miyezo yoyenera ndi mafotokozedwe:
1. Miyezo yapadziko lonse lapansi: API 5L: yogwiritsidwa ntchito paipi yachitsulo yonyamula mapaipi, imatanthawuza kukula ndi zofunikira za chitoliro chachitsulo cha spiral ASTM A252: chogwiritsidwa ntchito ku chitoliro chachitsulo chomangika, chimatanthawuza kukula ndi kupanga zofunikira za chitoliro chachitsulo chozungulira.
2. Muyezo wadziko lonse: GB / T 9711: yogwiritsidwa ntchito ku chitoliro chachitsulo cha kayendedwe ka mafuta ndi gasi, imatchula zofunikira zaumisiri za chitoliro cha zitsulo zozungulira. gb/t 3091: yogwiritsidwa ntchito paipi yowotcherera yachitsulo pamayendedwe amadzimadzi otsika, imatanthawuza kukula ndi zofunikira zaukadaulo wa chitoliro chachitsulo chozungulira.
