Kawirikawiri ogaŵikana metric magetsi welded zitsulo chitoliro, magetsi welded woonda-mipanda chitoliro, thiransifoma kuzirala chitoliro cha mafuta ndi zina zotero.

5.Spiral msoko womiza arc welded chitsulo chitoliropamayendedwe amadzimadzi opanikizika (SY5036-83) amapangidwa ndi zitsulo zotentha zopindika ngati machubu, zomwe nthawi zambiri zimapangidwa mozungulira kutentha, komanso kuwotcherera ndi mbali ziwiri zowotcherera arc. Amagwiritsidwa ntchito pamayendedwe opanikizika amadzimadzi. Spiral seam steel pipe. Chitoliro chachitsulo chimakhala ndi mphamvu yonyamula mphamvu komanso ntchito yabwino yowotcherera. Pambuyo pofufuza ndi kuyesa kosiyanasiyana kwa sayansi, ndizotetezeka komanso zodalirika kugwiritsa ntchito. The awiri a chitoliro zitsulo ndi lalikulu, dzuwa mayendedwe ndi mkulu, ndi ndalama atagona mapaipi akhoza kupulumutsidwa. Amagwiritsidwa ntchito makamaka pamapaipi onyamula mafuta ndi gasi.

6. Spiral seam high-frequency welded steel pipe for pressurized fluid transportation (SY5038-83) imapangidwa ndi koyilo yachitsulo yotentha ngati chubu lopanda kanthu, lomwe nthawi zambiri limapangidwa ndi kutentha, komanso kumangiriridwa ndi kuwotcherera kwafupipafupi. Amagwiritsidwa ntchito pamayendedwe opanikizika amadzimadzi. Spiral msoko mkulu pafupipafupi welded zitsulo chitoliro. Chitoliro chachitsulo chimakhala ndi mphamvu zonyamula mphamvu komanso pulasitiki yabwino, yomwe ndi yabwino kwa kuwotcherera ndi kukonza. Pambuyo pakuwunika ndi kuyesa kosiyanasiyana kwasayansi, ndizotetezeka komanso zodalirika kugwiritsa ntchito. Amagwiritsidwa ntchito kwambiri pakuyika mapaipi onyamula mafuta, gasi, etc.

7. Nthawi zambiri, ozungulira msoko kumizidwa arc welded zitsulo chitoliro (SY5037-83) kwa otsika-anzanu madzimadzi kutengerapo amapangidwa ndi otentha adagulung'undisa koyilo zitsulo monga chubu akusowekapo, amene nthawi zambiri spirally anapanga, ndipo amapangidwa ndi awiri mbali imodzi basi. kuwotcherera arc pansi pamadzi kapena kuwotcherera mbali imodzi. Mipope yachitsulo yolowetsedwa ndi arc yolumikizira madzi ambiri otsika ngati madzi, gasi, mpweya ndi nthunzi.

8. Spiral seam high-frequency welded steel pipe (SY5039-83) yotumiza madzimadzi otsika kwambiri imapangidwa ndi koyilo yachitsulo yotentha ngati chubu chopanda kanthu, nthawi zambiri chimapangidwa mozungulira kutentha kwambiri, ndikuwotcherera ndi chitsulo chokwera pafupipafupi. potumiza madzimadzi otsika kwambiri. Msoko wapamwamba pafupipafupi welded zitsulo chitoliro.

9. Mipope yachitsulo yozungulira yozungulira (SY5040-83) imapangidwa ndi zitsulo zotentha zotentha ngati machubu opanda kanthu, nthawi zambiri amapangidwa ndi ma spiral ofunda, ndipo amapangidwa ndi kuwotcherera kwa arc kuwirikiza mbali ziwiri kapena kuwotcherera kwafupipafupi. Amagwiritsidwa ntchito pomanga nyumba, ma wharfs, Bridges ndi milu ina ya maziko okhala ndi mapaipi achitsulo.
