Kusiyana pakati pa mapaipi opanda msoko ndi mapaipi achitsulo olumikizidwa

1. Zipangizo zosiyanasiyana:
*Chitoliro chachitsulo cholumikizidwa: Chitoliro chachitsulo cholumikizidwa chimatanthauza chitoliro chachitsulo chokhala ndi mipata ya pamwamba yomwe imapangidwa mwa kupindika ndi kusintha mizere yachitsulo kapena mbale zachitsulo kukhala mawonekedwe ozungulira, amakona anayi, kapena ena, kenako kuwotcherera. Chitoliro chomwe chimagwiritsidwa ntchito powotcherera chitoliro chachitsulo ndi mbale yachitsulo kapena chitsulo cholumikizidwa.
*Chitoliro chachitsulo chopanda msoko: Chitoliro chachitsulo chopangidwa ndi chidutswa chimodzi chachitsulo chopanda zolumikizira pamwamba, chotchedwa chitoliro chachitsulo chopanda msoko.

2. Ntchito zosiyanasiyana:
*Mapaipi achitsulo olumikizidwa: angagwiritsidwe ntchito ngati mapaipi amadzi ndi gasi, ndipo mapaipi olumikizidwa olunjika olumikizidwa otambalala kwambiri amagwiritsidwa ntchito ponyamula mafuta ndi gasi pogwiritsa ntchito mphamvu yamagetsi, ndi zina zotero; Mapaipi olumikizidwa ozungulira amagwiritsidwa ntchito ponyamula mafuta ndi gasi, mapaipi ozungulira, ma doko a mlatho, ndi zina zotero.
*Chitoliro chopanda msoko: chomwe chimagwiritsidwa ntchito pobowola mapaipi a petroleum geological, mapaipi osweka a petrochemicals, mapaipi a boiler, mapaipi onyamula katundu, komanso mapaipi achitsulo opangidwa mwaluso kwambiri pamagalimoto, mathirakitala, ndi ndege.

3. Magulu osiyanasiyana:
*Mapaipi achitsulo olumikizidwa: Malinga ndi njira zosiyanasiyana zolumikizira, amatha kugawidwa m'mapaipi olumikizidwa a arc, mapaipi olumikizidwa okhala ndi ma frequency apamwamba kapena otsika, mapaipi olumikizidwa ndi gasi, mapaipi olumikizidwa ndi ng'anjo, mapaipi a Bondi, ndi zina zotero. Malinga ndi momwe amagwiritsidwira ntchito, amagawidwanso m'mapaipi olumikizidwa wamba, mapaipi olumikizidwa ndi galvanized, mapaipi olumikizidwa ndi okosijeni, manja a waya, mapaipi olumikizidwa ndi metric, mapaipi ozungulira, mapaipi opompa madzi akuya, mapaipi agalimoto, mapaipi osinthira, mapaipi opindika okhala ndi makoma opindika, mapaipi opangidwa ndi mawonekedwe apadera, ndi mapaipi olumikizidwa ndi spiral.
*Mapaipi achitsulo chosasunthika: Mapaipi osasunthika amagawidwa m'mapaipi otsekedwa ndi kutentha, mapaipi otsekedwa ndi ozizira, mapaipi okokedwa ozizira, mapaipi otuluka, mapaipi apamwamba, ndi zina zotero. Malinga ndi mawonekedwe opingasa, mapaipi achitsulo chosasunthika amagawidwa m'mitundu iwiri: yozungulira ndi yosasinthasintha. Mapaipi osasinthasintha ali ndi mawonekedwe ovuta monga sikweya, elliptical, triangular, hexagonal, vwende seed, star, ndi finned payipi. M'mimba mwake waukulu ndi, ndipo m'mimba mwake wocheperako ndi 0.3mm. Malinga ndi zolinga zosiyanasiyana, pali mapaipi okhuthala okhala ndi makoma ndi mapaipi owonda.
