Mapaipi Ozungulira Ozungulira Ozungulira Omwe Amalowa M'madzi Ochokera Kumakampani Amakono

Mapaipi Ozungulira Ozungulira Omwe Amaviikidwa M'madzi a Makampani Amakono Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

M'mafakitale ambiri amakono, mainjiniya ndi akatswiri nthawi zonse amafunafuna mayankho abwino kwambiri kuti akwaniritse zosowa zosiyanasiyana za zomangamanga ndi mayendedwe. Pakati pa ukadaulo wambiri wopanga mapaipi womwe ulipo,chitoliro chozungulira chozungulira chozungulira(SSAW) yakhala chisankho chodalirika komanso chotsika mtengo. Cholinga cha blog iyi ndikuwunikira zabwino ndi zovuta zomwe zimabwera chifukwa cha ukadaulo watsopano wopanga mapaipi.

Ubwino wa chitoliro cholumikizidwa ndi arc chozungulira:

1. Kapangidwe kogwira mtima:

Mapaipi a SSAW ali ndi kapangidwe ka spiral weld komwe kamalola kupanga bwino komanso kuchepetsa nthawi yopangira. Khalidwe lapaderali limapangitsa kuti likhale chisankho choyamba pa ntchito zazikulu zomanga monga mafuta ndimapaipi a gasi, makina otumizira madzi, ndi mapulatifomu obowolera m'mphepete mwa nyanja. Njira yowotcherera yopitilira imatsimikizira kuti kapangidwe kake ndi kolimba kwambiri, zomwe zimawonjezera kulimba ndi moyo wa ntchito ya chitoliro.

2. Mphamvu yabwino kwambiri komanso kusinthasintha:

Kapangidwe ka chitoliro cha SSAW kamawonjezera mphamvu yake, zomwe zimapangitsa kuti chizitha kupirira kupsinjika kwakunja ndi kwamkati. Mapaipi awa amatha kupirira nyengo yovuta kwambiri, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito pamwamba ndi pansi pa nthaka. Kuphatikiza apo, kusinthasintha kwa mapaipi a SSAW kumalola kuti azisinthidwa mosavuta ndikuyikidwa m'malo osiyanasiyana, kuphatikizapo malo ovuta komanso nthaka yosakhazikika.

3. Yankho lotsika mtengo:

Njira zowotcherera mosalekeza zimawonjezera kupanga bwino pamene zimachepetsa kwambiri zolakwika ndi ndalama zowotcherera. Kuphatikiza apo, mapaipi ovekedwa ndi arc ozungulira omwe ali pansi pamadzi amapereka mphamvu komanso kulimba kwapamwamba, amachepetsa ndalama zokonzera ndi kukonza pa moyo wawo wonse, zomwe zimapangitsa kuti akhale chisankho chotsika mtengo kwa makampani.

Kuwotcherera kwa Arc Yokhala ndi Helical Drived

Mavuto omwe amakumana nawo ndi mapaipi ozungulira ozungulira omwe amalumikizidwa ndi arc welded:

1. Kulamulira khalidwe:

Chifukwa cha njira zovuta zowotcherera zomwe zimagwiritsidwa ntchito popanga mapaipi ozungulira ozungulira, kuonetsetsa kuti zinthu zikuyenda bwino nthawi zonse kumakhala kovuta. Ngati magawo owotcherera sakuwongoleredwa molondola, zolakwika zowotcherera monga kudula pansi, ma pores, ndi kusowa kwa fusion zidzachitika. Kuti athetse vutoli, njira zowongolera khalidwe ndi njira zowunikira zapamwamba panthawi yopanga zinthu ndizofunikira kwambiri.

2. Kuletsa kwa mapaipi m'mimba mwake:

Ngakhale mapaipi olumikizidwa ndi arc welded ozungulira ndi abwino kwambiri pakugwiritsa ntchito mainchesi akuluakulu, sangakhale oyenera mafakitale omwe amafuna mapaipi ang'onoang'ono. Njira yopangirayi ndi yothandiza kwambiri pa mapaipi akuluakulu, zomwe zimapangitsa kuti pakhale kupezeka kochepa kwa mapulojekiti ang'onoang'ono monga mapaipi okhala m'nyumba ndi ntchito zazing'ono zamafakitale. Pazofunikira izi, njira zina zopangira mapaipi ziyenera kuganiziridwa.

3. Chophimba pamwamba:

Vuto lina lomwe makampani opanga mapaipi a SSAW akukumana nalo ndikuonetsetsa kuti pali zokutira pamwamba zoyenera komanso zokhazikika kuti zisawonongeke ndi kuwonongeka. Kugwiritsa ntchito zokutira pamwamba pa malo ozungulira kumafuna zida zapamwamba komanso ukatswiri kuti zitsimikizire kuti zikuphimba bwino komanso zimamatira bwino. Kuphimba pamwamba koyenera ndikofunikira kwambiri kuti pakhale nthawi yayitali yogwira ntchito ya chitoliro cholumikizidwa ndi arc, makamaka m'malo ovuta.

Pomaliza:

Mapaipi olumikizidwa ndi arc welded ozungulira atsimikizira kuti ndi ukadaulo wopindulitsa kwambiri m'makampani amakono, womwe umapereka magwiridwe antchito, mphamvu komanso kugwiritsa ntchito ndalama moyenera. Msoko wake wapadera wa spiral weld umalola kupanga bwino komanso kulimba kwambiri, zomwe zimapangitsa kuti ukhale woyenera ntchito zazikulu zomanga. Komabe, kuti zinthu zipitirire kuyenda bwino komanso kugwiritsa ntchito ukadaulo uwu popanga zinthu, mavuto monga kuwongolera khalidwe, kuchuluka kochepa kwa mainchesi, ndi zokutira pamwamba ziyenera kuthetsedwa. Pothana ndi mavutowa kudzera mu kupita patsogolo kwa ukadaulo ndi mgwirizano wamakampani, spiral submedium arc welded pipe ili ndi tsogolo labwino posintha ndikusunga zomangamanga zofunika padziko lonse lapansi.
