Kurongwa kweEN 10220 Series
EN 10220zvichienderana nehuwandu hwekuenzana kwemapombi nezvimwe zvinhu zvawo. Kune matatu akatevedzana.
nhevedzano 1: dhayamita dzekunze uko zvese zvinodiwa pakuvaka masisitimu emapaipi zvakajairwa;
nhevedzano yechipiri: dhayamita dzekunze dzisingashandiswe zvese;
nhevedzano 3: dhayamita dzekunze dzine zvishongedzo zvishoma zvakajairwa zviripo.
Machati ehuremu hwepombi eEN 10220 Series 1
OD yepombi iyi inotevedzera zvinodiwa nenyika dzese kana zveindasitiri chaizvo, uye musika unopa zvinhu zvakajairwa zvakakwana zvakaita semaflange, macoupling, uye magokora.
Kugadziriswa kwakazara uku kunoita kuti dhizaini nekuisa zvive nyore uye kunoderedza kudiwa kwezvikamu zvisiri zvemhando yepamusoro uye mari yekugadzirisa.
Machati ehuremu hwepombi eEN 10220 Series 2
Chikamu cheOD chemhando iyi yemapaipi chakaenzana, asi hazvisi zvese zvinogadziriswa. Zvimwe zvinogadziriswa, zvakaita semaflange kana magokora, zvinogona kuwanikwa, nepo zvimwe zvikamu zvingada kugadziriswa, zvichiwedzera mutengo nekuoma kweprojekiti.
Machati ehuremu hwepombi eEN 10220 Series 3
Izvi zvinowanzoitika kana paine saizi dzemapaipi dzakanyatsojeka kana dzisina kujairika dzinoda huwandu hwakawanda hwezvishandiso nezvikamu zvakagadzirwa, zvichiwedzera mutengo wekugadzira nekushandisa chirongwa ichi, pamwe nekurebesa nguva yekutenga nekugadzira.
Machati eUremu hweMapaipi eUkobvu hweMadziro 70 -100 mm
Kune machubhu ane madziro akakora ane ukobvu hwemadziro kubva pa70 mm kusvika 100 mm, zvinodiwa zvakataurwa mu EN 10220, Tafura 2.
Zvishongedzo zvemachubhu emadziro anorema ane saizi dzinoenderana neTafura 2 zvinogona kusawanikwa zvisinei nenhevedzano iri muTafura 1 iyo dhayamita yekunze yakakodzera yakagoverwa.
Isu tiri vagadziri vemapaipi esimbi ecarbon emhando yepamusoro uye vatengesi vanobva kuChina, uye tiri vagadziri vemapaipi esimbi asina musono, tichikupai mhinduro dzakasiyana-siyana dzemapaipi esimbi!
