Izinsiza zephayiphi zensimbi zixhunywe ukuze zixhunywe nezinsimbi zensimbi. Ziyimikhiqizo yokucubungula ephumayo embonini yephayiphi zensimbi, ezisetshenziselwa ukuhlanganiswa kwephayiphi ngezinqubo ezifana nokuhlanganiswa kwe-socket, ukuxhumana okunezintambo, ukuxhumana kwe-flange, noma ukuxhumana okusheshayo ukuze kuhlangatshezwane nezidingo ezahlukene zobunjiniyela.

Ihlukaniswe ngokusebenza, izinsiza zephayiphi zensimbi zifaka ikakhulukazi izinsiza zokufaka (ezixhumanisa amaphayiphi amabili aqondile), ama-reducers (axhumanisa amaphayiphi anobubanzi obuhlukile), ama-elbows (njenge 90° noma 45° elbows, asetshenziselwa ukushintsha umkhondo wamaphayiphi), ama-tees (okwakhiwa kwamaphayiphi), kanye nezinsiza zokuxhuma (okwakhiwa okuphambene). Ngokwehlukaniswa kwezinto, izinsiza zephayiphi zensimbi zingahlukaniswa zibe izigaba ezintathu: insimbi ebomvu, ibhasi, kanye ne-bronze. Izinsiza zephayiphi zensimbi ebomvu (njenge T2 noma TP2) zinejazi elibomvu, zine-dactility enhle, kanye nokuhamba kahle kokushisa nokuhamba kukagesi, futhi zisetshenziswa kakhulu emanzini, ekupholiseni, nasezishintsheni zokushisa. Izinsiza zephayiphi zibhasi (ama-alloys ensimbi ne-zinc, njenges H59 noma H62) zinezimfanelo ezinhle zomshini, kulula ukuzenza, futhi ziqinile ekugugumeni, okwenza kube yohlobo olusetshenziswa kakhulu, ikakhulukazi ezifanele emanzini, igesi, kanye nezinsiza zokuhlanzeka. Izinsiza zephayiphi ze-bronze (ezine-insimbi, itini, i-phosphorus, njll.) zineziqu eziphakeme, ziqinile ekugqokeni nasekugugumeni, ikakhulukazi ziqinile ekugugumeni kwamanzi olwandle, futhi zisetshenziswa kakhulu ekwakhiweni kwemikhumbi, emikhiqizweni ye-chemical, nasezimishini ezinzima. Ngokwemigomo yokuxhuma, izinsiza zephayiphi zensimbi zifaka ukuxhumana okunezintambo (oxhumanisa ngokuqinisa izintambo zangaphakathi nezangaphandle, ezifanele izinhlelo eziphansi zok pressure ezifana namapayiphi amanzi noma amapayiphi egasi), ukwelashwa kwe-socket (iphayiphi lifakwa ngaphakathi kwe-socket futhi lwelashwa, linikeza amandla aphezulu okuxhumana nokuhlala kahle, ezifanele izinhlelo eziphezulu zok pressure nezishisayo ezifana nezinsiza zokupholisa noma amaphayiphi e-hydraulic oil), ukuxhumana kwe-flange (oxhumanisa nge-flanges kanye nezimbobo ezine-gasket yokuhlala phakathi, ezifanele amaphayiphi amakhulu noma amaphayiphi adinga ukuhoxiswa kaningi), kanye nezixhumi ezisheshayo (njengezixhumi zokucindezela noma izixhumi ezisheshayo, zakhelwe nge-snap-fit ​​noma izinhlelo zokuvula, zivumela ukuxhumana okusheshayo nokuhoxiswa ngaphandle kwezinsiza, zisetshenziswa kakhulu nezinsiza ze-pneumatic noma ezimeni ezidinga ukuhoxiswa nokuhlanganiswa kaningi). Izinsiza zephayiphi zensimbi zisetshenziswa kakhulu ezinsizeni zokupholisa, ezinhlelweni zokuhlinzeka ngamanzi, ezimotweni, emikhumbini, nasezinhlelweni zokuhlunga amanzi olwandle. Emkhakheni wokwakha, zisetshenziswe ezinhlelweni zokuhlinzeka ngamanzi emaphrojekthi afana neGreat Hall of the People kanye neNational Centre for the Performing Arts eBeijing. Ngokuthuthukiswa kwezinga lokusebenza kwamandla okushisa, ukusetshenziswa kwezinsiza zephayiphi zensimbi ezishintsheni zokushisa kuye kwanda, lapho izinsiza zokupholisa nezokupholisa zenza cishe u-75% wokusetshenziswa kwephayiphi zensimbi.
