Zofunikira paukadaulo wamapaipi owotchera msoko wowongoka: Zofunikira paukadaulo ndikuwunika mapaipi owongoka msoko zimatengera muyezo wa GB3092 wa "Welded Steel Pipes for Low-Pressure Fluid Transport". M'mimba mwake mwadzina wa welded chitoliro ndi 6 ~ 150mm, mwadzina khoma makulidwe ndi 2.0 ~ 6.0mm, ndi kutalika kwa welded chitoliro Nthawi zambiri 4 ~ 10 mamita, akhoza kutumizidwa ku fakitale mu utali wokhazikika kapena angapo utali. Pamwamba pa chitoliro chachitsulo chiyenera kukhala chosalala, ndipo zolakwika monga kupindika, ming'alu, delamination, ndi kuwotcherera lap siziloledwa. Pamwamba pa chitoliro chachitsulo chimaloledwa kukhala ndi zolakwika zazing'ono monga zokopa, zowonongeka, zowonongeka, zopsereza, ndi zipsera zomwe sizidutsa kupotoza koyipa kwa makulidwe a khoma. Kukula kwa makulidwe a khoma pa weld ndi kukhalapo kwa mipiringidzo yamkati kumaloledwa. Mapaipi achitsulo opangidwa ndi welded amayenera kuyesedwa pamakina, kuyezetsa kusalala, ndi kuyesa kukulitsa, ndipo akuyenera kukwaniritsa zomwe zafotokozedwa muyeso. Chitoliro chachitsulo chiyenera kupirira mphamvu ya mkati ya 2.5Mpa ndikusunga kutayikira kwa mphindi imodzi. Amaloledwa kugwiritsa ntchito njira yodziwira zolakwika za eddy m'malo mwa kuyesa kwa hydrostatic. Kuzindikira zolakwika za Eddy kumachitika ndi muyezo wa GB7735 "Eddy Current Flaw Detection Inspection Method for Steel Pipes". Njira yodziwira zolakwika pakali pano ndikukonza kafukufuku pa chimango, kusunga mtunda wa 3 ~ 5mm pakati pa kuzindikira zolakwika ndi weld, ndikudalira kuyenda kofulumira kwa chitoliro chachitsulo kuti chifufuze mozama za weld. Chizindikiro chozindikira cholakwika chimasinthidwa zokha ndikusankhidwa ndi chowunikira cha eddy chapano. Kukwaniritsa cholinga chozindikira zolakwika. Pambuyo pozindikira cholakwika, chitoliro chowotcherera chimadulidwa kutalika kwake ndi macheka owuluka ndipo amagubuduza pamzere wopangira kudzera pa flip frame. Nsonga zonse ziwiri za chitoliro chachitsulo ziyenera kukhala zafulati-chamfere ndi chizindikiro, ndipo mapaipi omalizidwa ayenera kupakidwa m'mitolo yamakona atatu asanachoke kufakitale.

Njira yoyendetsera chitoliro chachitsulo chowongoka: Chitoliro chachitsulo chowongoka ndi chitoliro chachitsulo chomwe msoko wake wowotcherera umakhala wofanana ndi njira yotalikirapo ya chitoliro chachitsulo. Mphamvu ya chitsulo chitoliro zambiri apamwamba kuposa mowongoka msoko welded chitoliro. Itha kugwiritsa ntchito mabatani ocheperako kuti ipange mapaipi owotcherera okulira m'mimba mwake, ndipo imathanso kugwiritsa ntchito mabaluti a m'lifupi mwake kuti apange ma diameter a mapaipi. Osiyana welded mapaipi. Komabe, poyerekeza ndi mipope yowongoka yautali womwewo, kutalika kwa weld kumawonjezeka ndi 30 ~ 100%, ndipo liwiro lopanga ndilotsika. Ndiye njira zake zogwirira ntchito ndi ziti?

1. Kupanga zitsulo: Njira yogwiritsira ntchito mphamvu yomwe imagwiritsa ntchito mphamvu yobwerezabwereza ya nyundo yowonongeka kapena kukakamiza kwa makina osindikizira kuti asinthe chopanda kanthu mu mawonekedwe ndi kukula komwe tikufuna.
2. Extrusion: Ndi njira yopangira zitsulo zomwe zitsulo zimayikidwa mu silinda yotsekedwa yotsekedwa ndipo kupanikizika kumagwiritsidwa ntchito pamapeto amodzi kuti atulutse zitsulo kuchokera ku dzenje lovomerezeka lakufa kuti apeze chinthu chomaliza cha mawonekedwe ndi kukula kwake. Amagwiritsidwa ntchito kwambiri popanga zitsulo zopanda chitsulo. Chuma chakuthupi.
3. Kugudubuza: Njira yopangira mphamvu yomwe chitsulo chopanda kanthu chimadutsa pampata (wamitundu yosiyanasiyana) pakati pa odzigudubuza ozungulira. Chifukwa cha kuponderezedwa kwa odzigudubuza, gawo lazinthu limachepetsedwa ndipo kutalika kumawonjezeka.
4. Chitsulo chojambula: Ndi njira yogwiritsira ntchito yomwe imakoka chitsulo chopanda kanthu (chofanana, chubu, mankhwala, etc.) kupyolera mu dzenje lakufa kuti muchepetse gawo la mtanda ndikuwonjezera kutalika kwake. Ambiri a iwo ntchito ozizira processing.
