Mapaipi Akasungirirwa Akakombama eMapaipi eGasi ePasi pevhu EN10219
Yedumapaipi akasungirirwa anotendererandiyo mhinduro yakanaka kumapurojekiti apo kuramba ngura uye kusimba kwechimiro kwakakosha. Maitiro akasiyana ekubatanidza mavhiri anotenderera haangowedzere simba repombi chete, asiwo anopa nzvimbo isina musono, zvichideredza njodzi yekudonha kwemvura nekukundikana. Izvi zvinoita kuti zvive zvakakodzera zvikuru munzvimbo dzakaoma dzinowanzo sangana nadzo mukushandiswa kwepasi pevhu.
Mwero we EN10219 unoita kuti mapaipi edu agadziriswe nemazvo uye nemhando yepamusoro, zvichiita kuti akwanise kumira nematambudziko ekutakurwa kwegasi rechisikigo. Akatarisana nekusimba uye kuvimbika, mapaipi edu akasungirirwa nesimbi akagadzirwa kuti ashande kwenguva refu, zvichideredza kudiwa kwekugadzirisa nekutsiviwa nguva nenguva.

Kuwedzera pakuvakwa kwavo kwakasimba, mapaipi aya akareruka uye ari nyore kubata, zvichiita kuti kuiswa kwacho kuve nyore uye kusingadhuri. Ungave uri kutanga chirongwa chitsva chemapaipi kana kuvandudza sisitimu iripo, mapaipi edu akasungirirwa nesimbi anopa musanganiswa wakakwana wesimba, kuchinjika, uye kutevedzera mitemo yeindasitiri.
Sarudza mapaipi edu esimbi anosungirirwa anoenderana nezvinodiwa nemapaipi egasi epasi pevhu uye unakirwe nerugare rwepfungwa runouya nekushandisa zvigadzirwa zvinoenderanaEN10219mitemo.
