Ubwino Wogwiritsa Ntchito PIPI ZOCHITA ZA SPIRALLY WELDED ASTM A252

Ubwino Wogwiritsa Ntchito SPIRALLY WELDED STEEL PIPES ASTM A252 Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Pomanga mapaipi a mafakitale osiyanasiyana, kusankha zinthu ndikofunikira. Spiral welded steel pipe, makamaka omwe amapangidwa ku miyezo ya ASTM A252, yakhala chisankho chodziwika bwino pamagwiritsidwe ambiri chifukwa cha zabwino zake zambiri.

Tsatanetsatane wa Zamalonda

Zolemba Zamalonda

Chimodzi mwazabwino zazikulu zogwiritsira ntchito ASTM A252 spiral welded steel chitoliro ndi mphamvu yake yayikulu komanso kulimba. Mapaipiwa amatha kupirira kupsinjika kwakukulu ndi katundu wolemetsa, kuwapanga kukhala abwino kufalitsa mafuta ndi gasi, mayendedwe amadzi ndi ntchito zamapangidwe. Njira yowotcherera yozungulira yomwe imagwiritsidwa ntchito popanga imatsimikizira mgwirizano wamphamvu komanso wogwirizana, zomwe zimalola chitoliro kupirira malo ovuta.

Kusanthula Kwazinthu

Chitsulocho sichiyenera kukhala ndi phosphorous yoposa 0.050%.

Kusiyanasiyana Kololedwa Pakulemera Ndi Makulidwe

Utali uliwonse wa mulu wa chitoliro uyenera kuyezedwa padera ndipo kulemera kwake sikuyenera kusiyana kuposa 15% kapena 5% pansi pa kulemera kwake, kuwerengeredwa pogwiritsa ntchito kutalika kwake ndi kulemera kwake pa kutalika kwake.

Kuzungulira kwakunja sikuyenera kusiyanasiyana kupitilira ± 1% kuchokera m'mimba mwake mwadzina

Makulidwe a khoma nthawi iliyonse sayenera kupitirira 12.5% pansi pa makulidwe omwe atchulidwa

Utali

Kutalika kwachisawawa kamodzi: 16 mpaka 25ft (4.88 mpaka 7.62m)

Kutalika kwapawiri: kupitirira 25ft mpaka 35ft(7.62 mpaka 10.67m)

Utali wofanana: kusiyanasiyana kovomerezeka ±1in

Kuwonjezera pa mphamvu,mapaipi achitsulo opangidwa ndi mpweya ASTM A252imapereka kukana kwambiri kwa dzimbiri. Izi ndizofunikira makamaka pamapaipi omwe amakumana ndi zovuta zachilengedwe kapena zinthu zowononga. Kuphimba koteteza pamapaipiwa kumawonjezera kukana kwawo kwa dzimbiri, kuwonetsetsa kuti moyo wawo wautumiki utalikirapo komanso kutsika mtengo wokonza.

Kuphatikiza apo, mapaipi achitsulo opangidwa ndi spirally welded ASTM A252 amadziwika chifukwa cha kusinthasintha kwake komanso kosavuta kuyika. Mapangidwe awo osinthika amatha kusinthidwa mosavuta kuti akwaniritse zofunikira za pulojekiti, pomwe mawonekedwe awo opepuka amapangitsa kunyamula ndi kuyenda mosavuta. Izi zimawapangitsa kukhala otsika mtengo posankha ntchito zosiyanasiyana, chifukwa akhoza kuikidwa mofulumira komanso moyenera, kuchepetsa ntchito ndi nthawi yomanga.

Ubwino wina wogwiritsa ntchito ASTM A252 spiral welded steel chitoliro ndikukhazikika kwake kwachilengedwe. Opangidwa kuchokera ku zinthu zomwe zingagwiritsidwenso ntchito, mapaipiwa amatha kugwiritsidwanso ntchito kapena kusinthidwanso kumapeto kwa moyo wawo wothandiza, kuchepetsa kuwonongeka kwa chilengedwe pakumanga ndi kukonza mapaipi. Kuonjezera apo, moyo wake wautali komanso zofunikira zochepetsera zowonongeka zimathandizira kuti pakhale chitukuko chokhazikika komanso chogwirizana ndi chilengedwe.

Pomaliza, mapaipi achitsulo opangidwa ndi spirally welded ASTM A252 ali ndi maubwino angapo omwe amapanga chisankho choyamba pakumanga mapaipi. Mphamvu zawo zazikulu, kulimba, kukana dzimbiri, kusinthasintha komanso kusasunthika kwa chilengedwe zimawapangitsa kukhala oyenerera ntchito zosiyanasiyana m'mafakitale osiyanasiyana. Posankha mapaipi awa, opanga pulojekiti amatha kuonetsetsa kuti paipi yodalirika komanso yokhalitsa yomwe imakwaniritsa miyezo yapamwamba kwambiri komanso yogwira ntchito.
