Izixhumi zephayiphi zensimbi zisetshenziswa ukuhlanganisa amaphayiphi ensimbi. Ziyimikhiqizo yokucubungula ethuthukisiwe emkhakheni wamaphayiphi ensimbi, zisetshenziswa ekuhlanganiseni amaphayiphi ngezindlela ezifana nokuhlanganiswa kwe-socket, ukuxhumana okunezintambo, ukuxhumana kwe-flange, noma ukuxhumana okusheshayo ukuze kuhlangatshezwane nezidingo ezahlukene zobunjiniyela.

Ihlukaniswe ngokusebenza, izinsiza zephayiphi zensimbi zensimbi zifaka ikakhulukazi izinsiza ze-sleeve (ezixhumanisa amaphayiphi amabili aqondile), ama-reducers (axhumanisa amaphayiphi anobubanzi obuhlukile), ama-elbows (njenge 90° noma 45° elbows, asetshenziselwa ukushintsha indlela yamaphayiphi), ama-tees (okwakha ama-branching epayiphu), kanye nezinsiza ze-cross (okwakha ama-branching anjenge-cross). Ngokusho kokuhlukaniswa kwezinto, izinsiza zephayiphi zensimbi zingahlukaniswa zibe izingxenye ezintathu: insimbi ebomvu, ibhasi, kanye ne-bronze. Izinsiza zephayiphi zensimbi ebomvu (njenge T2 noma TP2) zine-color ebomvu, zine-ductility enhle, kanye nokuhamba kahle kokushisa nokuhamba kwe-electrical, futhi zisetshenziswa kakhulu emanzini, ekufrigeration, nasezishintsheni zokushisa. Izinsiza zephayiphi zibhasi (ama-alloys ensimbi ne-zinc, njenge H59 noma H62) zinezakhiwo ezinhle zomshini, kulula ukuzenza, futhi ziqinile ekugugeni, okwenza zibe uhlobo olusetshenziswa kakhulu, ikakhulukazi ezifanele emanzini, igesi, nasezimpahleni zokuhlanzeka. Izinsiza zephayiphi ze-bronze (ezine-insimbi, itini, i-phosphorus, njll.) zine-strength ephezulu, ziqinile ekugqokeni nasekugugeni, ikakhulukazi ziqinile ekugugeni kwamanzi olwandle, futhi zisetshenziswa kakhulu ekwakheni izikebhe, emikhiqizweni ye-chemical, nasezinhlelweni ezinzima. Ngokusho kwezindlela zokuxhuma, izinsiza zephayiphi zensimbi zifaka izixhumanisi ezine-thread (exhunywe ngok tightening internal and external threads, ezifanele izinhlelo ezine-pressure ephansi ezifana namaphayiphi amanzi noma amaphayiphi egasi), i-socket welding (iphayiphi ifakwa kwi-socket bese iwelded, inikeza amandla aphezulu okuxhuma kanye nokuhlala kahle, ezifanele izinhlelo ezine-pressure ephezulu nezishisayo ezifana ne-refrigeration noma amaphayiphi e-hydraulic oil), izixhumanisi ze-flange (exhunywe nge-flanges kanye nezibambo ezine-gasket yokuhlala phakathi, ezifanele amaphayiphi anobubanzi obukhulu noma amaphayiphi adinga ukuhoxiswa kaningi), kanye nezixhumanisi ezisheshayo (njenge compression fittings noma quick-release fittings, zakhiwe nge-snap-fit ​​noma izindlela zokuvula, zivumela ukuxhumana nokuhoxiswa ngokushesha ngaphandle kwezinsiza, zisetshenziswa kakhulu nezinsiza ze-pneumatic noma ezimweni ezidinga ukuhoxiswa nokuhlanganiswa kaningi). Izinsiza zephayiphi zensimbi zisetshenziswa kakhulu kumadivayisi e-refrigeration, ezinhlelweni zokuhlinzeka ngamanzi ezakhiweni, ezimotweni, ezikebheni, nasezinhlelweni zokuhlunga amanzi olwandle. Emkhakheni wokwakha, zisetshenziswe ezinhlelweni zokuhlinzeka ngamanzi ezinhlelweni ezifana ne-Great Hall of the People kanye ne-National Centre for the Performing Arts eBeijing. Ngokuthuthukiswa kwezinga lokusebenza kwe-air conditioning, ukusetshenziswa kwezinsiza zephayiphi zensimbi ezishintsheni zokushisa kuye kwanda, lapho imishini ye-air conditioning kanye ne-refrigeration ithatha cishe u-75% wokusetshenziswa kwephayiphi zensimbi.
