Arc welding inzira inoshandiswa zvakanyanya mukugadzira pombi, kunyanya kune zvikumbiro zvinosanganisira mvura yepasi. Nekudaro, senge chero maindasitiri maitiro, anouya nematambudziko ayo ega. Mune ino blog, isu tichaongorora zvakajairwa matambudziko anosanganikwa nawo panguva yepipeline arc welding uye nekupa mhinduro dzinoshanda kuti ive yemhando yepamusoro, uye yakasimba chigadzirwa chagadzirwa.
Fekitori yedu iri muCangzhou, Hebei Province uye yanga iri pamberi pekugadzira pombi kubvira 1993. Fekitori yedu inovhara nzvimbo ye350,000 square metres uye ine 680 vashandi vehunyanzvi. Isu tinodada nekushandisa advanced spiral undermerged arc welding tekinoroji, iyo inova nechokwadi chemhando yepamusoro uye kusimba kwezvigadzirwa zvedu. Iyi teknolojia yemazuva ano yakagadzirirwa kusangana nepamusoro-soro yemvura yepasi, zvichiita kuti mapaipi edu ave akavimbika uye anogara kwenguva refu ekugadzirisa kushandiswa kwakasiyana-siyana.
Zvakajairwa Zvinetso zveArcWelded Pipe
1. Kusapindirana weld quality: Imwe yezvinetso zvinowanzoitika mu arc welding ndeyekuwana inopindirana weld quality. Kusiyana kwekupisa kwekupisa, kumhanya kwekufamba, uye kona ye electrode inogona kukonzera kushaya simba kana kusakwana.
Solution: Kushandisa akasimba emhando yekudzora matanho uye kushandisa otomatiki welding masisitimu anogona kubatsira kuchengetedza kuenderana. Kugara uchidzidziswa ma welders pane akanakisa maitiro uye kushandisa yepamusoro yekutarisa tekinoroji kunogona zvakare kuvandudza weld mhando.
2. Kushandura uye kupeta: Kupisa kunogadzirwa panguva yekugadzira kusungirirwa kunogona kuita kuti pombi ikotame kana kuti iparadze, zvichiita kuti irege kurongeka uye inogona kukanganisa mukushandiswa.
Solution: Preheating pombi usati welding uye kushandisa kwakakodzera clamping matekiniki anogona kuderedza kukanganisa. Pamusoro pezvo, kushandisa akawanda-pass welding matekiniki anogona kubatsira kugovera kupisa zvakaenzana, kuderedza njodzi yehondo.
3. Porosity uye Inclusions: Kuvapo kwehomwe yemhepo (porosity) kana kunze kwenyika (inclusions) mu weld inogona kukanganisa kuvimbika kwepombi.
Solution: Kuve nechokwadi chenzvimbo yekushanda yakachena uye kushandisa yepamusoro-mhando yekuzadza zvinhu zvinogona kuderedza zvakanyanya njodzi yeporosity uye inclusions. Kugara uchiongorora welding midziyo uyearc welding pombikunokoshawo kuchengetedza utsanana.
4. Kutsemuka: Nekuda kwekukurumidza kutonhora kana zvisina kufanira welding matekiniki, kuputika kunogona kuitika, zvichikonzera kukanganisa kwemaitiro epombi.
Solution: Kudzora kutonhora mitengo uye kushandisa preheating matekiniki anogona kubatsira kudzivirira kutsemuka. Uye zvakare, kusarudza iyo yakakodzera yekuzadza zvinhu inoenderana nemidziyo yevabereki inogona kuwedzera kuramba kwe weld pakutsemuka.
5. Kupinda Kusina Kukwana: Kupinda kusina kukwana kunogona kukonzera kubatana kusina simba kunogona kukundikana pasi pekumanikidzwa.
Solution: Kugadzirisa welding parameters senge voltage uye ikozvino inogona kuwedzera weld kudzika. Kunyatsoongorora uye kuyedzwa kweweld kuchabatsirawo kuona nekugadzirisa matambudziko ese pombi isati yaiswa.
mukupedzisa
Panzvimbo yedu yeCangzhou, tinonzwisisa kukosha kwekukunda matambudziko aya akajairwa arc welding kugadzira pombi inosangana nemhando yepamusoro yemhando uye kusimba. Nekushandisa advanced spiral undermerged arc welding tekinoroji, tinoona kuti zvigadzirwa zvedu hazvisi kungovimbika chete asiwo zvinokwanisa kuzadzisa zvinodiwa zvakasiyana-siyana zvekushandisa, kunyanya mumagadzirirwo emvura yepasi.
Nekutarisana nematambudziko aya nekuita mhinduro dzinoshanda, tinogona kuramba tichipa vatengi vedu zvigadzirwa zvemhando yepamusoro zvinomira muyedzo wenguva. Kunyangwe iwe uchida mapaipi ekuvaka, zvivakwa kana maindasitiri ekushandisa, kuzvipira kwedu kune mhando uye hunyanzvi hunovimbisa kuti iwe unowana yakanakisa mhinduro kune zvaunoda.
