Ipayipi Lokudonsa lisetshenziswa kakhulu engalweni yokuhudula yeTrailing Suction Hopper Dredger (TSHD) noma ileli lokusika le-Cutter Suction Dredger (CSD). Uma kuqhathaniswa namapayipi okukhipha, amapayipi okumunca angamelana nengcindezi engemihle ngaphezu kwengcindezi enhle, futhi angasebenza ngokuqhubekayo ngaphansi kwezimo zokugoba eziguquguqukayo. Angamapayipi enjoloba abalulekile kuma-dredger.

Izici eziyinhloko ze-Suction Hose ukumelana nokuguguleka okuhle, ukumelana nesimo sezulu, kanye nokuguquguquka.

Ngokuvamile ingcindezi yokusebenza ephezulu yama-Suction Hoses ifinyelela ku--0.1 MPa, kanti ingcindezi yokuhlola i--0.08 MPa. Ama-Suction Hoses anezidingo ezikhethekile noma ezenziwe ngokwezifiso, njengalezo ezingamelana nengcindezi esukela ku--0.1 MPa kuya ku-0.5 MPa, nawo ayatholakala. Ama-Suction Hoses afanele amazinga okushisa aphakathi nendawo asukela ku--20℃ kuya ku-50℃, futhi afanele ukudlulisa izingxube zamanzi (noma amanzi olwandle), udaka, udaka, ubumba nesihlabathi, asukela ku-gravity ethile kusuka ku-1.0 g/cm³ kuya ku-2.0 g/cm³.

Amapayipi okumunca e-CDSR ahambisana nezidingo ze-ISO28017-2018 yezinga lamazwe ngamazwe kanye nezindinganiso zoMnyango Wezimboni Zamakhemikhali waseShayina HG/T2490-2011, futhi angahlangabezana nezidingo zokusebenza komkhiqizo eziphakeme nezinengqondo ezivela kumakhasimende.

Ngokwezimo zokusebenza ezahlukene, ngokuvamile kunezinhlobo ezine zamapayipi okumunca: ipayipi lokumunca eline-nipple yensimbi, ipayipi lokumunca eline-sandwich flange, ipayipi lokumunca eline-armored kanye nepayipi lekhoni lensimbi eliyingxenye.
