Chiyambi cha Shandong Kungang Spiral Pipe
Chitoliro chozungulira chimapangidwa ndi kugudubuza chitsulo chochepa cha carbon carbon structural steel kapena chitsulo chochepa cha alloy structural chitsulo mu chubu chopanda kanthu molingana ndi ngodya ina ya helical (yotchedwa ngodya yopangira), ndiyeno kuwotcherera nsonga za chitoliro. Itha kupangidwa ndi yocheperako Mzere Chitsulo chimapanga mipope yayikulu yachitsulo. Mafotokozedwe ake amawonetsedwa ndi makulidwe akunja * khoma. Chitoliro chowotcherera chiyenera kuonetsetsa kuti kuyesa kwa hydraulic, mphamvu yamagetsi ya weld ndi kuzizira kozizira kuyenera kukwaniritsa malamulo.
Kumbali ya kuwotcherera ndondomeko, njira kuwotcherera ozungulira welded chitoliro ndi molunjika msoko zitsulo chitoliro ndi yemweyo, koma molunjika msoko welded chitoliro mosalephera ndi zambiri zowotcherera T-zoboola pakati, kotero Mwina kuwotcherera zilema nawonso kwambiri kuchuluka, ndi zotsalira zowotcherera pazitsulo zooneka ngati T Kupsyinjika ndi kwakukulu, ndipo zitsulo zowotcherera nthawi zambiri zimakhala zovuta zitatu, zomwe zimawonjezera kuthekera kwa ming'alu. Komanso, malinga ndi malamulo luso mivi arc kuwotcherera, aliyense weld ayenera kukhala arc poyambira ndi arc kuzimitsira mfundo, koma aliyense molunjika msoko welded chitoliro sangathe kukumana chikhalidwe ichi pamene kuwotcherera msoko zozungulira, kotero pakhoza kukhala More kuwotcherera zilema.
ntchito
Mapaipi ozungulira amagwiritsidwa ntchito makamaka mu engineering ya madzi, mafakitale a petrochemical, makampani opanga mankhwala, mafakitale amagetsi, ulimi wothirira, komanso zomangamanga zamatawuni. Ndi imodzi mwazinthu zazikulu makumi awiri zopangidwa ndi dziko lathu. Kwa mayendedwe amadzimadzi: madzi, ngalande, uinjiniya wa zimbudzi, mayendedwe amatope, mayendedwe amadzi am'nyanja. Zoyendera gasi: gasi, nthunzi, mpweya wamafuta amafuta. Zolinga zomanga: monga mipope yowunjika ndi milatho; mapaipi a ma wharves, misewu, nyumba zomangira, mapaipi owunjikira m'madzi, ndi zina.
Miyezo ya Zamalonda
Spiral msoko kumizidwa arc welded zitsulo chitoliro SY5036-83 kwa ampanikidwe madzimadzi kayendedwe zimagwiritsa ntchito mafuta ndi gasi mapaipi; ozungulira msoko mkulu pafupipafupi welded chitsulo chitoliro SY5038-83 kwa ampanikidwe madzimadzi kayendedwe ndi welded ndi mkulu pafupipafupi lap kuwotcherera. Spiral seam high-frequency welded steel mapaipi kuti ayendetse madzimadzi mopanikizika. Chitoliro chachitsulo chimakhala ndi mphamvu zonyamula mphamvu, pulasitiki yabwino, ndi yabwino kwa kuwotcherera ndi kukonza; SY5037-83 wozungulira msoko wothira madzi arc welded chitsulo chitoliro SY5037-83 pamayendedwe otsika otsika kwambiri amadzimadzi amapangidwa ndi kuwotcherera mbali ziwiri kapena mbali imodzi yamadzi, gasi, mipope yachitsulo yomizidwa ndi arc yotumizira madzi ambiri otsika. monga mpweya ndi nthunzi.
Miyezo yodziwika bwino ya mipope yachitsulo yozungulira imagawidwa kukhala: SY/T5037-2000 (muyezo wautumiki, womwe umadziwikanso kuti spiral seam submerged arc welded steel mapaipi amapaipi wamba oyendera madzimadzi), GB/T9711.1-1997 (muyezo wadziko lonse, komanso otchedwa mafuta ndi gasi makampani zoyendera zitsulo mipope) Gawo loyamba la zobereka zinthu luso: A-kalasi zitsulo chitoliro (GB/T9711.2 B-kalasi zitsulo chitoliro ndi zofunika kwambiri), API-5L (American Petroleum Institute, amatchedwanso pipeline chitoliro chachitsulo; chomwe chimagawidwa m'magulu awiri: PSL1 ndi PSL2), SY/T5040-92 (piral submerged arc welded steel pipe kwa milu).
