Pre-paipi yotsekera nthunzi ndi chitoliro chotchingidwa ndi makina opangira magetsi otenthetsera m'mafakitale. Pakupanga mafakitale ndi kufalitsa mphamvu, nthunzi, monga chonyamulira chotentha kwambiri, chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Komabe, mapaipi amtundu wa nthunzi amakumana ndi zovuta monga kutayika kwakukulu kwa kutentha, kukwera mtengo kwa kukonza, komanso kuyika kovutirapo panthawi yotumizira, zomwe zimakhudza mphamvu zonse zamagetsi komanso phindu lazachuma. Kuti tithane ndi izi, takhazikitsa chida chathu chatsopano - Pre-paipi ya nthunzi yotsekeredwa. Pre-paipi yotsekera nthunzi idapangidwa kuti izikhala bwino ndi makina otumizira nthunzi, yopereka mphamvu kwambiri, kupulumutsa mphamvu, komanso kulimba.
Mafotokozedwe Akatundu
Pre-paipi ya insulated ndi njira yophatikizika yamapaipi. Amapangidwa pogwiritsa ntchito zida zodzitchinjiriza zapamwamba komanso njira zolondola, amakhala ndi-zotsekera zomwe zidayikidwa kale komanso zoteteza musanachoke kufakitale. Kapangidwe kameneka kamachepetsa kwambiri-masitepe omangira malo ndikuwonetsetsa kuti inchi ikugwira ntchito mofananamo komanso yokhazikika. Choncho, -paipi yotsekera nthunzi ndiyoyenera kutumiza{7}}kutalika kwa nthunzi yotentha kwambiri{8}}makamaka m'mafakitale omwe ali ndi zofunikira zoletsa kutentha, monga malo opangira magetsi, malo opangira mankhwala, ndi malo opangira zakudya. Kutentha kwanthawi zonse kwa -paipi ya nthunzi yotsekeredwa kale ndi -50 degrees mpaka 350 degrees .

Mphamvu zamabizinesi
Yakhazikitsidwa mu 2005, Hebei Yugang Pipeline Manufacturing Co., Ltd. ndi kampani yodziwika bwino{{3}kuchokera ku Yanshan, Cangzhou, mzinda wodziwika bwino popanga zida zamapaipi. Pambuyo pazaka khumi zachitukuko mwachidwi, kampaniyo idasintha kwambiri mu 2014, ndikumanga gulu lamakono lomwe limagwira ntchito yonse yamapaipi. Masiku ano, kampaniyi imayang'ana kwambiri-zogulitsa zapamwamba, monga-mapaipi atatu a polyethylene (3PE) anti-ndi ma mapaipi akuluakulu{11}}akuluakulu ozungulira amafuta ndi gasi. Okonzeka ndi mizere 16 yodzipangira okha, kampaniyo ili ndi mphamvu yopanga pachaka ya matani 300,000. Kuphatikiza apo, kampaniyo nthawi zonse imatsatira malingaliro opanga "kuwongolera bwino kwambiri," kupititsa patsogolo miyezo yopangira mosalekeza. Sichinangodutsa chiphaso chapadziko lonse cha ISO9001 komanso chalandira ziphaso zitatu kuchokera ku American Petroleum Institute (API), kuphatikiza API Spec 5L. Nthawi yomweyo, kampaniyo imachita zambiri pazatsopano ndi kafukufuku ndi chitukuko, ndipo mu 2024, idalandira kuzindikirika mdziko lonse chifukwa cha luso lake laukadaulo.
