Underground Direct Buried Insulated Steel Pipe amagwiritsidwa ntchito kwambiri mu netiweki yamadzi ndi gasi yotumizira mapaipi, mapulojekiti otsekereza mapaipi amafuta mu petroleum, mankhwala, ma netiweki apakati ndi zotenthetsera, mapaipi apakati{0}}owongolera mpweya, ndi mainjiniya a tauni.
Underground Direct Buried Insulated Steel Pipe ndiwolunjika-yokwiriridwa kale ndi chitoliro cha chitsulo cha thermal Insulation chomwe chimagwira ntchito bwino, chitetezo ndi kudalirika, komanso kutsika mtengo.
Kufotokozera
1. Chitoliro cha -chotsekeredwa kale chotsekedwa ndi thovu la polyurethane cholimba kwambiri chimatha kupirira kutentha mpaka madigiri 140 c.
2. Ndi dzimbiri kugonjetsedwa HDPE jekete chitoliro akhoza kupanga chitoliro mwachindunji m'manda mobisa popanda ngalande.
3. Chitoliro chamitundu yosiyanasiyana ndi zoyikapo zitoliro zimatha kugwira ntchito zosiyanasiyana zotenthetsera ndi kuziziritsa.
4. Makulidwe a thovu a polyurethane amatha kupangidwa kuchokera ku 26.5-83mm kapena kupitilira apo.
Zogulitsa Zamalonda
Chitoliro chachitsulo chogwira ntchito
Chigawo chapakati, chomwe chimanyamula sing'anga (monga madzi otentha kapena nthunzi), chimapangidwa ndi chitoliro chapamwamba kwambiri-chopanda msoko kapena chomangika mozungulira ndipo chimayenera kutsata milingo yapaipi yapaipi (monga 100% kuyang'ana kwa radiographic).
Insulation
Foam yolimba ya polyurethane (kachulukidwe 60-80 kg/m³) ndiye chinthu choyambirira, chopatsa kutenthetsa kotsika (0.013-0.03 kcal/m:h· digiri ) ndi kutsekedwa-chiyerekezo cha selo Kuposa kapena kofanana ndi 90%, kumachepetsa kutenthedwa bwino. Pazotentha-zotentha kwambiri (monga mapaipi a nthunzi), chimagwiritsidwa ntchito chosanjikiza, chosunthika chokhazikika (kuphatikiza ndi aluminiyamu wonyezimira wonyezimira) chimagwiritsidwa ntchito, chomwe chimatha kupirira madigiri 150 -450 .
Chitoliro chakunja
High-density polyethylene (HDPE) or steel-in-steel (double-layer steel pipe structure) provides corrosion resistance, waterproofing, and mechanical protection. The HDPE outer pipe requires corona treatment on the inner surface, has a density >940 kg/m³, and a tensile strength >20 MPa. Njira yopangira mafakitale imatengera kukhazikitsidwa kwa fakitale ndikumangirira kophatikizika, kuphatikiza kuchotsa dzimbiri kwa mapaipi achitsulo, kudzaza thovu pansanjika yotsekereza, ndikuyika mapaipi oteteza akunja kuti atsimikizire kuti zigawo zitatuzi ndi zomangika.
Ubwino Wakuchita
Mphamvu Mwachangu
Kutentha kwa kutentha ndi 25% yokha ya mapaipi achikhalidwe, ndipo kutentha kwapaipi kumachepera 2% (kuposa muyezo wapadziko lonse wa 10%).
01
Moyo Wautali ndi Kukaniza Kuwonongeka
Chitoliro chakunja cha HDPE/Fiberglass chimalekanitsa chinyezi cha mpweya, zomwe zimapangitsa kuti chitoliro chachitsulo chikhale chochepa kwambiri, zomwe zimapangitsa kuti moyo ukhale wa zaka 30-50 (kuchuluka kwa 3-4 kuposa mapaipi achikhalidwe).
02
Kusalowa madzi ndi Chinyezi-Umboni
Chotsekedwa-chithovu cha cell polyurethane chimakhala ndi kuchuluka kwa madzi otsika (pafupifupi 0.2 kg/m²), ndipo kamangidwe ka chisindikizo kumalepheretsa madzi kusefukira pomanga.
03
Kuwunika Chitetezo
Alamu yolumikizidwa-monga kutayikira imapeza zomwe zatsikira.
04
Zomangamanga Zachuma
Kukumba kumachepetsedwa ndi 50% ndipo kugwiritsa ntchito konkire kumachepetsedwa ndi 90%. Kupanga fakitale limodzi ndi{3}}kudula mitengo pamalo kumafupikitsa nthawi yomanga ndi 50%.
05
Kugwiritsa Ntchito
Kutentha kwapakati/kuziziritsa, -kutentha kwambiri kwa nthunzi, mafuta a petrochemicals, malo opangira magetsi. Kutentha kwa chigawo, mapaipi a mafakitale monga mankhwala, mankhwala, ndi mapaipi amafuta.

Zocheperapo kapena zofanana ndi digirii 120 (pamwamba pa 140 digiri) pakuwotcha wamba, mpaka madigiri 450 a mapaipi a nthunzi. |
Milandu ya Project
Fakitale Yathu
Hebei Yugang Pipe Manufacturing Co., Ltd. ili ku Yanshan Economic Development Zone ku Cangzhou, mkati mwa makampani a mapaipi aku North China. Yakhazikitsidwa mu 2005, kampaniyo idakwezedwa mu 2014 kukhala gulu lathunthu lophatikiza ukadaulo wamapaipi, kupanga zida, ndi kupanga Chalk. Zopangapanga zaukadaulo mu 2024 zapangitsa kuti izindikirike ngati bizinesi-yaukadaulo wapamwamba. Zogulitsa zake zazikulu ndi ma 3PE anti{10}}mapaipi achitsulo amafuta ndi gasi, ma spiral welded, mapaipi otsekeredwa, ndi zolumikizira. Kampaniyi ili ndi mizere isanu yopangira mapaipi ozungulira, mizere itatu yoletsa -yopangira dzimbiri, mizere isanu ndi umodzi yotsekera mapaipi, ndi mizere iwiri yowongoka yopangira mapaipi, yomwe imatha kupanga matani 300,000 pachaka. Kampaniyo ndi yovomerezeka ya ISO9001, ndipo zogulitsa zake zimagwirizana ndi miyezo yapadziko lonse ya API Spec 5L/5CT/5B.
