Chitoliro chachitsulo chakuda, yomwe imatchedwanso kutichitoliro chachitsulo cha kaboni, chitoliro chofewa chachitsulo, ndi mtundu wa mapaipi opangidwa ndi chitsulo chopanda mpweya wambiri. Maonekedwe ake amdima amachokera ku sikelo yakuda ya oxide yomwe imapanga pamwamba pake popanga.
Kawirikawiri, mapaipi akuda achitsulo ndi mapaipi ozungulira osakonzedwa, makamaka okonzedwa kuti apangidwe pamwamba. Chifukwa chosowa chophimba choteteza, amatha kuwononga kwambiri, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito m'malo ouma kapena komwe angapakidwe utoto kapena kutetezedwa mwanjira ina. Amadziwika kuti ndi olimba komanso okhazikika, mapaipi akuda achitsulo ndi chisankho chodziwika bwino pa ntchito zapakhomo ndi zamafakitale. Amabwera m'makulidwe ndi makulidwe osiyanasiyana, zomwe zimapangitsa kuti pakhale ntchito zosiyanasiyana zomangira ndi kukhazikitsa.

2. Mitundu yosiyanasiyana ya mapaipi achitsulo chakuda

Malinga ndi njira zosiyanasiyana zopangira, mapaipi akuda achitsulo amagawidwa makamaka m'mapaipi achitsulo olumikizidwa ndi mapaipi achitsulo osapindika.

Chitoliro chachitsulo cholumikizidwa:Chitoliro chachitsulo cholumikizidwa chimapangidwa ndi mbale zachitsulo zolumikizidwa kapena zingwe zokulungidwa mu chubu. Chimadziwikanso kuti chitoliro cha ERW (Electric Resistance Welded). Mtundu uwu wa chitoliro nthawi zambiri umakhala ndi mphamvu komanso kulimba bwino. Njira yopangira chitoliro chachitsulo cholumikizidwa ndi yosavuta, ndipo imatha kupanga zigawo zazitali za chitoliro pamtengo wotsika.

Chitoliro Chopanda Msoko cha Chitsulo:Chitoliro chachitsulo chopanda msoko chimapangidwa pogwiritsa ntchito njira yotentha kapena yozizira yozungulira popanda misoko yolumikizidwa. Mtundu uwu wa chitoliro umakhala ndi mphamvu komanso chitetezo chambiri pansi pa kupanikizika kwakukulu komanso mikhalidwe yovuta kwambiri chifukwa ulibe malo ofooka (monga ma weld).

3. Kodi chitoliro chachitsulo chakuda n'chiyani?

Chitoliro chakuda chimagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana, kuphatikizapo mapaipi, kugawa gasi, ndi chithandizo cha kapangidwe kake.

Chitoliro chachitsulo chosasokonekeraimapangidwa popanda mipata kapena ma weld, zomwe zimawonjezera mphamvu zake ndikupangitsa kuti ikhale njira yotetezeka yonyamulira mpweya ndi madzi pansi pa kuthamanga kwambiri. Mtundu uwu wa chitoliro umayamikiridwa makamaka pakugwiritsa ntchito komwe kulimba kwa kapangidwe kake ndikofunikira, monga m'mapaipi amafuta ndi gasi.
Mbali inayi,chitoliro chachitsulo chakuda cholumikizidwaimagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana, kuphatikizapo mapaipi amadzi, njira zotumizira gasi ndi makina opopera moto. Kapangidwe kake kosagwira moto kamapangitsa kuti ikhale yoyenera machitidwe otere, komwe kudalirika ndi chitetezo ndizofunikira kwambiri.

4. Kuwongolera ndi Kutumiza Mapaipi Akuda

1) Panthawi yopanga komanso pambuyo pake, antchito a QC omwe ali ndi zaka zoposa 5 zokumana nazo amafufuza zinthu mwachisawawa.
2) Laboratory yovomerezeka ya dziko lonse yokhala ndi satifiketi za CNAS
3) Kuyang'aniridwa kovomerezeka kuchokera kwa munthu wina wosankhidwa/wolipidwa ndi wogula, monga SGS, BV.
4) Yavomerezedwa ndi Malaysia, Indonesia, Singapore, Philippines, Australia, Peru ndi UK. Tili ndi ziphaso za UL /FM, ISO9001/18001, FPC.

phunzirani zambiri za satifiketi

Kulongedza ndi Kutumiza:
Tsatanetsatane wa Kulongedza: m'matumba okhala ndi ma hexagonal okhazikika panyanja odzazidwa ndi zingwe zachitsulo, Ndi zingwe ziwiri za nayiloni pa phukusi lililonse.

Tsatanetsatane Wotumizira: Kutengera ndi QTY, nthawi zambiri masiku 20-30.

Doko Lotumizira: Doko la TIANJIN ku China
