Mapaipi achitsulo okhala ndi mphira
Mapaipi achitsulo okhala ndi rabara apangidwa kuti agwiritsidwe ntchito m'njira zosiyanasiyana zopopera. Ntchito monga kutulutsa madzi m'mphero, mapampu amphamvu kwambiri, mizere yayitali ya kumbuyo, kugwiritsa ntchito mapampu otayirira komanso mapaipi okoka mphamvu. Malekezero onse ali ndi flange yokhazikika yokhazikika ya rabara.
Chitoliro chachitsulo cholimba cha rabara cholimba komanso cholimba ndi dzimbiri chimapangidwa ndi chitoliro chachitsulo chodziwika bwino ngati chimango ndipo chimagwiritsidwa ntchito bwino kwambiri ngati rabara yolimba, yolimba ndi kutentha ngati layer. Chimaphatikizidwa ndi ukadaulo wapadera wokhala ndi guluu wochita bwino kwambiri. Chimagwiritsidwa ntchito makamaka mu zitsulo, magetsi, makampani opanga mankhwala, mafuta, malasha, simenti ndi mafakitale ena. Pantchito yamigodi, imagwiritsidwa ntchito kwambiri mumakina otumizira mipata ya migodi, malo osungiramo minda ya malasha ndi minda yogwirizana ndi mapaipi. Makamaka, payipiyi ndi yoyenera kwambiri kutumiza kutentha pakati pa -50°C mpaka +150°C, komwe ndikosavuta kuvala komanso dzimbiri. Titha kuwonjezera makulidwe a khoma pakona ya payipi malinga ndi zomwe kasitomala akufuna, motero kukulitsa moyo wa ntchito. Pakadali pano, moyo wa ntchito ya payipi yachitsulo yolimba ndi rabara ukhoza kufika zaka 15-40. Chitolirochi chikhoza kuzunguliridwa pafupifupi madigiri 90 patatha zaka 6-8 za ntchito. Nthawi iliyonse yozungulira imatha kukulitsa nthawi yotumikira, Chitoliro chachitsulo chikhoza kuphimbidwa ndi rabara mobwerezabwereza katatu mpaka kanayi, motero kuchepetsa kugwiritsa ntchito ndalama zambiri.

| Kutayika kwa abrasion ya atonal wosanjikiza (cm³/1.61km) ≤ | 0.1 |
| Kulimba kwa nsalu (mtundu wa Sauer A) | 60±5 |
| Kuchuluka kwa kusintha kwa mphamvu ya kutentha kwa ukalamba wa mkati (70℃ x 72 h, %) ≤ | 10 |
Mawonekedwe
1. Kapangidwe Kabwino Kwambiri
2. Kukana kuvala bwino komanso moyo wautali
3. Mphamvu yayikulu komanso kukana kwakukulu
4. Kukana dzimbiri kwabwino
5. Kutentha kwakukulu
6. Kulumikiza mwachangu komanso kuyika kosavuta
