ERW carbon steel pipevs chitoliro chozungulira:

Choyamba, kusiyana pakati pa kupanga
ERW mpweya zitsulo chitoliro ndi otentha adagulung'undisa koyilo kudzera mosalekeza mpukutu kupanga, ntchito mkulu-pafupipafupi panopa zotsatira za khungu ndi moyandikana zotsatira, kotero kuti m'mphepete mwa koyilo kutentha maphatikizidwe, kupanikizika mu Finyani wodzigudubuza pansi pamavuto kuwotcherera kuti tikwaniritse kupanga.Choncho, erw mpweya zitsulo chitoliro zotsalira nkhawa ndi yaing'ono, kudzera kuwotcherera kutentha mankhwala, sizing, kuwongola, kuthamanga kwa madzi ndi njira zina, kupsyinjika otsalira kupitirira kumasulidwa ndi kuchepetsa.Zochita zatsimikizira kuti erw mpweya zitsulo chitoliro mu yosungirako ndi ntchito yotsalira maganizo pa chitoliro zitsulo sizimakhudza.Popanda kuwotcherera waya, weld mu katundu thupi ndi mankhwala zikuchokera ndi mbale chimodzimodzi.Ubwino wa erw carbon steel chitoliro zimadalira mtundu wa pepala.

Spiral zitsulo chitoliro kudzera unit wozungulira rotary kuwotcherera waya pamodzi, mbale zitsulo mwa kasinthasintha wozungulira, kotero kuti maganizo geometric ndi zovuta, ndipo ena anafika malire zokolola za mbale zitsulo, ndi kozungulira chubu pambuyo mapangidwe kupsinjika kotsalira kotsalira, kupsinjika kotsalira ndikumangika kwamphamvu.Ndipo chitsulo chitoliro ndi kuthamanga mkati, khoma komanso kutulutsa mphete kumakokedwa maganizo, awiri superimposed, kuti athe kufooketsa chitoliro zitsulo.Kugwiritsa ntchito njirayi kumakhala kosatetezeka.Chitsulocho chimalumikizidwa pamodzi ndi waya wokhala ndi mankhwala, ndipo ming'alu ndi mikanda yowotcherera imatha kuchitika panthawi yowotcherera.Kotero kuti weld ndi m'munsi zitsulo mu thupi katundu ndi mankhwala zikuchokera momveka bwino.N'zosavuta kutulutsa kupanikizika kwakukulu mu mgwirizano ndi zitsulo zoyambira.Powotcherera, kutentha kumakhala kwakukulu, ndipo kuuma kumakhala kwakukulu.

Chachiwiri, kusiyana pakati pa zipangizo
Chitoliro chachitsulo cha ERW chomwe chimagwiritsidwa ntchito muzopangira chimapangidwa ndi koyilo yotentha yokhazikika, kapangidwe kake ndi zinthu zakuthupi ndizokhazikika.

Ambiri mwa ozungulira chitoliro chomera ntchito otsika kalasi otentha-anagulung'undisa Mzere, mankhwala zikuchokera ndi thupi katundu ndi kusakhazikika, zilema mkati ndi zosafunika kwambiri.Pokhapokha mumafuta ndi petrochemical system mkati mwa opanga zitoliro zazikulu zozungulira omwe amagwiritsa ntchito koyilo yowotcha yokhazikika kuti apange chitoliro chachitsulo kuti atsimikizire mtundu ndi chitetezo.

Chachitatu, mtengo wogula ndi zovuta zogula
Mafuta ndi petrochemical dongosolo lalikulu zitsulo chitoliro kupanga ozungulira zitsulo chitoliro, ubwino wake makamaka anaikira lalikulu m'mimba mwake zitsulo chitoliro kupanga, kupanga ndalama ndi otsika.Komabe, m'mimba mwake yaying'ono ndi yapakatikati (Φ114mm ~ Φ355.6mm) ya chitoliro chachitsulo, mtengo wopangira ndi wokwera, wapakati kuposa chitoliro chachitsulo cha ERW 8% mpaka 15%.

Large kozungulira zitsulo chitoliro chomera nthawi zambiri samatulutsa yaing'ono m'mimba mwake mozungulira zitsulo chitoliro, zogula zovuta kwambiri.Small ndi sing'anga awiri erw mpweya zitsulo chitoliro, chifukwa cha kuchuluka kwa opanga, zosavuta kugula.

Chachinayi, chitsulo chitoliro geometric kukula
1, ERW mpweya zitsulo chitoliro geometric kukula kulondola apamwamba;ndipo kulondola kwa geometry kwa chitoliro cha spiral welded ndikotsika, zomwe zimapangitsa kuti pakhale zovuta zomangira ma weld docking.
2, ERW mpweya zitsulo chitoliro kuwotcherera koyeneri ndi 100%;mulingo welded chitoliro kuwotcherera koyekwanira 130% -200%.Kutalika kwa chitoliro chozungulira ndi chotalika kwambiri kuposa chitoliro chachitsulo cha ERW, ndipo chiwerengero cha chilema chimawonjezeka.
3, ERW mpweya zitsulo chitoliro mkati weld ndi pafupi ziro, maso wamaliseche si kuwoneka;chitoliro chachitsulo chozungulira mkati ndi kunja kwapansi chiyenera kusiyidwa pafupifupi 0.3 mm kutalika (chomwe chimatsimikiziridwa ndi kupanga).Kuwotcherera kumakhala kwakukulu kwambiri kotero kuti pali kusiyana pakati pa zokutira (3PE) ndi chitoliro, zomwe zimapangitsa kukana kwa dzimbiri kwa chitoliro chachitsulo kuchepetsedwa kwambiri.

4, Chifukwa cha kukhalapo kwa chitoliro chachitsulo chozungulira, kufalikira kwamadzimadzi othamanga kwambiri kudzakhala chisokonezo chachikulu, kukulitsa kukana koyenda, kuchepetsa kuyendetsa bwino kwa payipi.ERW mpweya zitsulo chitoliro khoma ndi yosalala, palibe vuto ngati.
