Chitoliro chopanda msoko chimakhala ndi mphamvu yokakamiza, mphamvu ndipamwamba kuposa ERW welded chitoliro. Chifukwa chake imagwiritsidwa ntchito kwambiri pazida zothamanga kwambiri, komanso m'mafakitale otenthetsera, ma boiler. Nthawi zambiri kuwotcherera msoko wa welded zitsulo chitoliro ndi mfundo ofooka, khalidwe zimakhudza wonse ntchito.

Chitoliro chopanda msoko vs chitoliro chachitsulo chowotcherera:

1. Kusiyana kwa maonekedwe

Chitoliro chachitsulo chosasunthika chimagwiritsa ntchito billet yachitsulo ngati zopangira. Zowonongeka zakunja za billet sizingathetsedwe ndi njira yotentha yotentha, zimangopukutidwa pambuyo pomaliza. Pochepetsa khoma, chilemacho chimatha kuthetsedwa pang'ono.

Welded zitsulo chitoliro opangidwa ndi otentha adagulung'undisa koyilo monga zopangira, pamwamba khalidwe la koyilo ndi basi chitoliro pamwamba khalidwe, ndi zosavuta control.The pamwamba pa otentha adagulung'undisa koyilo ndi apamwamba.
Chifukwa chake Welded zitsulo chitoliro pamwamba khalidwe ndi bwino kuposa zitsulo chitoliro opanda msoko.

2. Kuumba Njira kusiyana
Chitoliro chosasunthika chachitsulo chikhoza kupangidwa nthawi imodzi mukugubuduza.
Welded zitsulo chitoliro ndi kupanga ndi zitsulo Mzere kapena mbale zitsulo, kudzera kupinda ndi njira zosiyanasiyana kuwotcherera.

3. Kuchita ndi Kugwiritsa Ntchito
Chitoliro chachitsulo chosasinthika chimakhala ndi mphamvu yothamanga, mphamvu ndi yoposa ERW welded chitoliro. Chifukwa chake imagwiritsidwa ntchito kwambiri pazida zothamanga kwambiri, komanso m'mafakitale otenthetsera, ma boiler.
Nthawi zambiri kuwotcherera msoko wa welded zitsulo chitoliro ndi mfundo ofooka, khalidwe zimakhudza wonse ntchito.

Nthawi zambiri, mapaipi achitsulo opangidwa ndi zitsulo amatha kuletsa 20% kupanikizika kocheperako kuposa opanda msoko. Kudalirika uku ndiye chifukwa chachikulu chomwe anthu amapitira ku chitoliro chachitsulo chosasinthika. Zowona zake, mapaipi onse amakampani amapangidwa ndi mapaipi opanda msoko chifukwa mapaipi amakumana ndi ntchito zotentha kwambiri, zamankhwala komanso zamakina. Mapaipi opangidwa ndi welded amakondedwa kwambiri m'mafakitale apamlengalenga, magalimoto ndi zamagetsi komwe bajeti ndi yotsika, komanso kukakamiza kwa mapaipi.

4. Likupezeka Kukula kusiyana
Ambiri opanga zitsulo zopanda msokonezo za chitoliro ku China, amapanga miyeso yoyambirira yopanda msoko pazipita OD mu inchi 20, 508 mm. Kumene nthawi zambiri kumakhala kochepa kuposa 16 inchi, 406.4 mm, chifukwa cha malire a zipangizo. Ndipo ngati kasitomala akufuna kugula chitoliro chachitsulo chosasunthika kuposa kukula kwake, ndiye kuti makina owonjezera otentha ayenera kugwiritsidwa ntchito. Koma kawirikawiri mtundu uwu otentha kukodzedwa opanda msokonezo zitsulo chitoliro khalidwe sakanakhoza kuyerekeza ndi choyambirira chosakanizika zitsulo chitoliro.

M'malo mwake, welded zitsulo chitoliro alibe zofooka izi, kukula kupezeka 1-1/2 inchi 48.3mm kuti 100 inchi 2540 mm.

5.Mtengokusiyana
Kawirikawiri mtengo wosasunthika zitsulo chitoliro ndi apamwamba kuposa mipope zitsulo welded, chifukwa zopangira, zipangizo kupanga ndi njira. Koma nthawi zina chifukwa cha kukakamizidwa kwa msika, chitoliro chowotcherera chimakhala chokwera mtengo, kotero ngati mutakumana ndi izi, musazengereze kugula chitoliro chachitsulo chosasunthika cha miyeso yofanana.
