Mapaipi eGasi Akasungirirwa Arc Akanyudzwa Kaviri: Maitiro Ekugadzirisa Mapaipi Anoshanda
Muminda yekuvaka neinjiniya, kuvimbika uye kusimba kwezvinhu zvakakosha. Tinopa ASTM A252 Double Submerged Arc Welded yepamusoro-soro(DSAW) mapaipi egasi akagadzirirwa kusangana nezvinodiwa zvakasimba zvemapombi ehwaro, mapombi emabhiriji, mapombi emapazi, nezvimwe zvakasiyana-siyana zvekushandisa muinjiniya. Akagadzirwa nesimbi yeA252 Grade 1, inozivikanwa nekusimba kwayo kwakanyanya uye kugara kwenguva refu, mapaipi edu egasi anovimbisa kuti chirongwa chako chakavakirwa pahwaro hwakasimba.
Simba Risingaenzaniswi uye Kugara Kwenguva Refu
ASTM A252 chiyero chakasimbiswa chave chichivimbwa nemainjiniya nenyanzvi dzekuvaka kwemakore mazhinji. Mapaipi edu egasi eDSAW akagadzirwa kuti agone kumira kumanikidzwa kwakanyanya uye akakodzera kushandiswa munzvimbo dzakasiyana-siyana dzinoda simba. Maitiro ekunamira anotonhora anoshandiswa mukugadzira mapaipi aya anovandudza hunhu hwawo hwemakanika, zvichiita kuti ave akakodzera kushandiswa uko kusimba kwechimiro kwakakosha. Nedumapaipi egasi, unogona kuva nechokwadi chekuti chigadzirwa chauri kushandisa chinosangana nezvinodiwa zvepamusoro-soro muindasitiri.

Tekinoroji yepamusoro yekushongedza
Tekinoroji yedu yeDouble Submerged Arc Welding (DSAW) yakachinja magadzirirwo anoitwa mapaipi esimbi. Iyi nzira yepamusoro yekuwelda inovimbisa weld yakasimba, yakafanana, iyo inowedzera simba rese repaipi. Maitiro eDSAW anosanganisira kushandisa ma arc maviri, ayo akanyudzwa pasi pechikamu che granular flux, zvichipa nzvimbo yekuwelda yakachena uye inoshanda. Izvi zvinoguma nekubatana kwakanaka, zvichideredza njodzi yekukanganisika uye zvichivimbisa kugara kwenguva refu kwepaipi.
ZVIMWE ZVINOSHANDISWA
Mapaipi edu egasi eASTM A252 DSAW anogona kushandiswa zvakasiyana-siyana uye anogona kushandiswa mumabasa akasiyana-siyana. Ungave uri kuvaka bhiriji, kuvaka nheyo, kana kuisa mapier piles, mapaipi edu anogona kusangana nezvinodiwa zvepurojekiti yako. Kusasimba kwawo pakumanikidzwa kwakanyanya kunoita kuti akwanise kushandiswa muminda yakasiyana-siyana yeinjiniya, kusanganisira mafuta negesi, kutakurwa kwemvura, uye mashandisirwo ekuvaka.
Simbiso yemhando yepamusoro
Pafekitori yedu yekugadzira, tinonyanya kukoshesa mhando padanho rega rega rekugadzira. Mapaipi edu anoedzwa zvakasimba kuti ave nechokwadi chekuti anosangana nezvinodiwa.ASTM A252zvinodiwa uye zvinopfuura zvinotarisirwa nevatengi. Tinonzwisisa kuti kubudirira kweprojekiti yenyu kunoenderana nezvinhu zvamunoshandisa, ndosaka takazvipira kukupai pombi yegesi yemhando yepamusoro.
Sei tichifanira kusarudza pombi yedu yegesi yeDSAW?
1. Simba Rakanaka: Mapaipi edu akagadzirwa nesimbi yeA252 Grade 1, iyo inopa Kugara kwenguva refu uye kuramba kumanikidzwa kwakanyanya.
2. Tekinoroji Yepamusoro Yekushongedza: Maitiro edu ekushongedza arc akapetwa kaviri anovimbisa kushongedza kwakasimba uye kwakafanana, zvichiwedzera kusimba kwese kwepombi.
3. Inoshandiswa zvakanyanya: Yakakodzera nzvimbo dzakasiyana dzeinjiniya, mapaipi edu egasi anogona kushandiswa pakuvaka mafoundation piles, bridge piles, piers, nezvimwewo.
4. Kuvimbiswa Kwemhando Yepamusoro: Tinotevedzera matanho akasimba ekudzora mhando kuti tive nechokwadi chekuti zvigadzirwa zvedu zvinosangana uye zvinopfuura mwero weindasitiri.
Zvose pamwe chete, pombi yedu yegesi yeASTM A252 inonyudzwa kaviri pasi pemvura isarudzo yakakodzera mainjiniya nenyanzvi dzekuvaka dziri kutsvaga zvinhu zvakavimbika uye zvemhando yepamusoro zvemapurojekiti avo. Tichitarisa pakusimba, kugara kwenguva refu, uye matekiniki ekugadzira epamusoro, tinodada nekupa zvigadzirwa zvinogara kwenguva refu. Sarudza pombi yedu yegesi yepurojekiti yako inotevera uye unzwe musiyano mumhando uye mashandiro.
