Mapaipi Owotchedwa Arc Owirikiza Pawiri Olimbikitsa Kukhulupirika Kwamapangidwe

Mapaipi Owotchedwa Arc Owirikiza Pawiri Owonjezera Kukhulupirika Kwachipangidwe Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Gawo ili la European Standard limatchula zaukadaulo woperekera magawo oziziritsa opangidwa ndi welds, magawo opanda dzenje a mawonekedwe ozungulira, masikweya kapena amakona anayi ndipo amagwira ntchito ku magawo amphako omwe amapangidwa ozizira popanda kutenthedwa pambuyo pake.

Cangzhou Spiral Steel Pipes Group Co., Ltd imapereka gawo lopanda kanthu la mipope yachitsulo yozungulira.

Tsegulani:

Pankhani ya zomangamanga zomangamanga, kufunika kogwiritsa ntchito zipangizo zabwino ndi njira zomangira sikungatheke.Pakati pa zigawo zosiyanasiyana zomwe zimagwiritsidwa ntchito pomanga, mapaipi amagwira ntchito yofunika kwambiri.Tidzawunikira kufunikira kwa mapaipi opangidwa ndi welded pawiri ndikuwunika mawonekedwe awo, mapindu ndi momwe angathandizire kukulitsa kukhulupirika kwamapangidwe.

Phunzirani za mapaipi owotcherera pawiri:

Chitoliro chowirikiza kawiri, chomwe chimadziwikanso kuti chitoliro chowirikiza cha arc (Mapaipi a DSAW), amapangidwa pogwiritsa ntchito njira yowotcherera ya arc pansi pamadzi.Tekinolojeyi imaphatikizapo kuphatikiza kwanthawi yayitali mbale ziwiri zachitsulo, zomwe zimapereka kulumikizana kolimba komanso kosalekeza.Mapaipiwa amagwiritsidwa ntchito makamaka pamapaipi othamanga kwambiri, mapaipi amadzi apansi panthaka ndi gasi, kufufuza mafuta, ndi nsanja zakunyanja.

Wonjezerani kukhulupirika kwa kamangidwe:

Chifukwa chachikulu chogwiritsira ntchitoiwiri welded chitolirondi kuthekera kwawo kupititsa patsogolo kukhulupirika kwawo.Ndi ma welds opanda msoko komanso amphamvu, mapaipi awa amapereka kukana kupsinjika kwapamwamba komanso kulimba.Kuwotcherera kawiri kumatsimikizira kuti chitolirocho chikhoza kupirira milingo yapamwamba kwambiri, ndikupangitsa kuti ikhale yabwino kwa ntchito zovuta pomwe kuwotcherera kumodzi kungasokoneze chitetezo chadongosolo.Njira yowotcherera yapawiriyi imachotsa kuthekera kwa kutayikira kapena ming'alu, kuwonetsetsa kudalirika kwanthawi yayitali kwa makina anu amapope.

Kuchuluka kwa mphamvu ndi kulemera kwa chiwerengero:

Pawiri welded chitoliro amapereka kwambiri mphamvu kulemera chiŵerengero.Chifukwa cha njira yowotcherera, mapaipiwa achepetsa makulidwe a khoma ndipo amakhala opepuka pomwe amasunga zolimba.Kupindula kwa mphamvu ndi kulemera kwachiŵerengerochi kumachepetsa katundu wonse pazitsulo zothandizira, zomwe zimapangitsa kuti zikhale zotsika mtengo zothetsera ntchito zazikulu monga milatho, nsanja, ndi nyumba zapamwamba.

Kulimbana ndi corrosion:

Ubwino winanso wa chitoliro chowotcherera pawiri ndi kukana kwa dzimbiri.Chisindikizo cholimba kwambiri chimapanga chotchinga cholimba motsutsana ndi zinthu zakunja, kuphatikiza chinyezi, mankhwala ndi nthaka.Izi zimalepheretsa mkati mwa chitoliro kuti zisagwirizane ndi zowonongeka zowonongeka, kuonetsetsa kuti moyo wautumiki utalikirapo poyerekeza ndi mapaipi ochiritsira.Mapaipiwa sachita dzimbiri ndi opindulitsa kwambiri pamakampani amafuta ndi gasi, pomwe mapaipi nthawi zambiri amakumana ndi zovuta.
