Gawo lotseguka komanso lotseka (gawo) limayendetsedwa ndi chidutswa cha valavu ya valavu ya val ndikuzungulira mozungulira tsinde la valavu. Amagwiritsidwa ntchito makamaka kudula kapena kulumikiza sing'anga mu bomba, ndipo amathanso kugwiritsidwa ntchito posintha madzi ndi kuwongolera. Valavu yamtunduwu iyenera kuyikidwa molunjika pa mapaipi.
Mawonekedwe a pulasitikiVarve Mbale:
.
. Kutentha kwa RPP ndikuyenera -20 ℃ ℃ ~ + 95 ℃; Kutentha kwa UPVC kumayenera -50 ℃ ℃ ~ + 95 ℃.
(3) Kukaniza kwabwino: RPP, UPVC, PVDF, CPVC ili ndi mphamvu zapamwamba komanso kukana.
.
. PRP amagwiritsidwa ntchito makamaka chakudya, zakumwa, madzi ampopi,
Madzi oyera ndi ziwalo zina zamadzimadzi zamadzimadzi ndi zida zopanda ukhondo zitha kugwiritsidwanso ntchito pamapaipi ndi zida zokhala ndi kuchepa kochepa;
RPP, UPVC, PPVC, CPVC imagwiritsidwa ntchito makamaka yofalitsidwa yamadzimadzi (gasi) yokhala ndi zitsulo zolimba, alkali olimba komanso osakaniza.
(6) Kuyika kosavuta ndi kusinthitsa kwabwino: Izi ndi zopepuka, zomangidwa kapena zolumikizidwa, zolimbitsa thupi zokwanira, zomanga zosavuta, komanso ntchito yayikulu kwambiri
Mawonekedwe akulu a valavu ya mpira wa mpirawo ndi kapangidwe kake, kusindikiza kodalirika, kovuta, komanso kukonza kovuta. Malo opindika komanso malo owoneka bwino nthawi zambiri amatsekedwa, sikophweka kuwonongeka ndi sing'anga, komanso yosavuta kuyigwiritsa ntchito ndi kusamalira. Ndioyenera madzi, ma sol sols ndi mafuta achilengedwe. Mng'alu wogwira nawonso ndi woyeneranso kwa sing'anga yogwira ntchito movutikira, monga mpweya wabwino, hydrogen peroxide, methane ndi ethylene, ndi zina zambiri. Thupi la mpira wa mpira limatha kukhala lophatikiza kapena lophatikizidwa.
