Spiral welded pipe (saw): Amapangidwa ndi kugubuduza otsika mpweya mpweya structural zitsulo kapena otsika aloyi structural zitsulo Mzere mu chubu akusowekapo molingana ndi ngodya inayake helical (otchedwa kupanga ngodya), ndiyeno kuwotcherera msoko chitoliro.Zitha kupangidwa ndi yopapatiza Mzere zitsulo umabala lalikulu m'mimba mwake zitsulo mipope.Mafotokozedwe ake amawonetsedwa ndi makulidwe akunja * khoma.Thewelded chitoliroziyenera kuwonetsetsa kuti kuyesa kwa hydraulic, mphamvu yowotcherera yowotcherera ndi kuzizira kozizira kuyenera kukwaniritsa malamulowo.

Ubwino wa spiral welded pipe:

(1) mipope zitsulo diameters osiyana akhoza kupangidwa pogwiritsa ntchito Mzere zitsulo m'lifupi chomwecho, makamaka mipope zitsulo awiri lalikulu akhoza kupangidwa ndi yopapatiza Mzere zitsulo.
(2) Pansi pa zovuta zomwezo, kupsinjika kwa msoko wowotcherera wozungulira kumakhala kocheperako kuposa msoko wowongoka, womwe ndi 75% mpaka 90% ya chitoliro chowongoka chowongoka, kotero chimatha kupirira kukakamiza kwakukulu.Poyerekeza ndi mipope yowongoka ya msoko wowongoka wokhala ndi m'mimba mwake womwewo wakunja, makulidwe a khoma amatha kuchepetsedwa ndi 10% mpaka 25% pamavuto omwewo.
(3) Makulidwe, kulolerana kwakukulu sikudutsa 0.12%, kupatukako kuli kochepera 1/2000, ndipo ellipticity ndi yochepera 1%.Nthawi zambiri, kukula ndi kuwongola njira kumatha kuchotsedwa.
(4) Ikhoza kupangidwa mosalekeza.Mwachidziwitso, imatha kupanga mapaipi achitsulo osatha.Kutayika kwa mutu ndi mchira ndikochepa, ndipo chitsulo chogwiritsira ntchito chitsulo chikhoza kuwonjezeka ndi 6% mpaka 8%.
(5) Poyerekeza ndi longitudinal welded chitoliro, ndi kusinthasintha ntchito ndi yabwino kusintha mitundu ndi kusintha.
(6) Chidacho ndi chopepuka komanso chochepa poyambira ndalama.Itha kupangidwa kukhala gawo lamtundu wa ngolo kuti apange mapaipi owotcherera mwachindunji pamalo omanga pomwe mapaipi amayikidwa.
(7) Ndikosavuta kuzindikira makina ndi makina.

Kuipa kwa spiral welded pipe ndi:chifukwa chopiringizika Mzere chitsulo ntchito ngati zopangira, pali ena kachigawo mapindikidwe, ndi kuwotcherera mfundo m'mphepete mwa zitsulo Mzere ndi elasticity, kotero si kophweka agwirizane kuwotcherera nyali, zimene zimakhudza kuwotcherera. khalidwe.Kuti muchite izi, zida zowunikira zovuta komanso zowunikira zabwino zimakhazikitsidwa.

Mayendedwe a chitoliro cha spiral welded:

Chifukwa chakuchulukirachulukira kwapaipi, kuchulukirachulukira kwa ntchito, komanso kufunikira kotalikitsa moyo wautumiki wa payipi momwe mungathere, chitukuko chachikulu cha chitoliro chowotcherera ndi:
(1) Kupanga mapaipi okhala ndi mipanda yayikulu kwambiri kuti muchepetse kuthamanga;
(2) Kupanga ndi kupanga mipope zitsulo ndi nyumba zatsopano, monga iwiri wosanjikiza mipope welded mipope, ndiye welded mipope iwiri wosanjikiza ndi Mzere zitsulo theka makulidwe a khoma chitoliro, amene si ali ndi mphamvu apamwamba kuposa wosanjikiza umodzi. mapaipi a makulidwe omwewo, komanso samawonekera kulephera kwamphamvu;
(3) Kupanga mitundu yatsopano yazitsulo, kuwongolera luso la smelting, ndipo ambiri amatengera luso lowongolera komanso kugudubuza zinyalala kuti lipititse patsogolo mphamvu, kulimba ndi kuwotcherera kwa thupi la chitoliro;

(4) mwamphamvu kukhala mipope TACHIMATA, monga ❖ kuyanika khoma lamkati la chitoliro ndi wosanjikiza odana dzimbiri, amene sangakhoze kutalikitsa moyo utumiki, komanso kusintha kusalala kwa khoma lamkati, kuchepetsa kukana madzimadzi kukangana, kuchepetsa sera. kudzikundikira ndi dothi, kuchepetsa kuchuluka kwa mipope yoyeretsera, ndi kuchepetsa mtengo wokonza.

PS:Welded zitsulo mapaipikukhala ndi mtengo wotsika komanso wokwera wopanga bwino kuposamachubu opanda msoko.Wowongoka msoko welded chitoliro ali ndi ndondomeko yosavuta kupanga, mkulu kupanga dzuwa, mtengo wotsika ndi chitukuko mofulumira.Mphamvu ya chitoliro chowotcherera chozungulira chimakhala chokwera kuposa chitoliro chowongoka.
