Chitoliro chachitsulo cha ASTM A252 Giredi 1/2/3 LSAW | OD 508-1422mm Chitoliro chachikulu cha Maziko a Chitsulo Chopangidwa ndi Wopanga ndi Wogulitsa

Chitoliro chachitsulo cha ASTM A252 Giredi 1/2/3 LSAW | Chitoliro chachitsulo cha maziko cha OD 508-1422mm chachikulu

Kufotokozera Kwachidule:

Mapaipi achitsulo a LSAW, ogwirizana ndi miyezo ya ASTM A252, ndi mapaipi achitsulo olimba kwambiri, okhala ndi mainchesi akuluakulu oyenera kupanga maziko, kumanga milatho, uinjiniya wa m'madzi, ndi mapulojekiti olemera a zomangamanga. Mapaipi achitsulo a LSAW amapereka mawonekedwe abwino kwambiri a kapangidwe kake, kusinthasintha bwino, komanso mphamvu zonyamula katundu, zomwe zimapangitsa kuti akhale oyenera kugwiritsa ntchito maziko akuya. Ma diameter akunja ndi kuyambira 508 mpaka 1422 mm. Mapaipi achitsulo a LSAW ogwirizana ndi ASTM awa adapangidwa malinga ndi zomwe makampani ndi miyezo yaposachedwa, kuonetsetsa kuti ali olimba kwambiri, makulidwe ofanana a makoma, komanso kulimba kwambiri ngakhale m'malo ovuta komanso m'madzi amchere.

Mapaipi achitsulo a LSAW awa ndi oyenera maziko a milatho, malo oimikapo madoko, nsanja za m'mphepete mwa nyanja, maziko a nyumba zazitali, ndi zomangamanga zamafakitale. Kugwirizana ndi makontrakitala ambiri odziwa bwino ntchito za EPC ndi mayankho omanga padziko lonse lapansi kumatsimikizira kuti amakhala ndi nthawi yayitali yogwira ntchito, kukana dzimbiri (ndi zokutira zina), komanso kuyika kosavuta.

Kugwiritsa Ntchito Kwambiri

1. Kumanga Maziko (Machitidwe Ozama a Maziko)

Amagwiritsidwa ntchito ngati maziko olimba a nyumba zazitali, mafakitale a mafakitale, nyumba zosungiramo katundu, malo ogulitsira zinthu, ndi nyumba zokhalamo. Mapaipi achitsulo awa amapereka mphamvu yolimba yonyamula katundu woyima ndipo amatsimikizira kuti kapangidwe kake kamakhala kolimba kwa nthawi yayitali m'nthaka yofooka kapena yofewa.

2. Uinjiniya wa Bridge Foundation

Zabwino kwambiri pa milatho yamisewu ikuluikulu, milatho ya sitima, misewu yokwezeka ya m'mizinda, ndi nyumba zodutsa pamwamba pa msewu.Milu yachitsulo ya ASTM A252 LSAW / EFWamagwiritsidwa ntchito kwambiri powoloka mitsinje, kuwoloka nyanja, ndi maziko a mlatho wowoloka nyanja, zomwe zimateteza bwino ku katundu wosinthasintha komanso kuyenda kwa nthaka.

3. Ntchito Yomanga Madoko ndi Zam'madzi

Amayikidwa m'malo oimikapo madoko, malo oimikapo makontena, malo oimikapo sitima, malo oimikapo madoko, ndi malo onyamulira katundu m'mphepete mwa nyanja. Mapaipi achitsulo awa adapangidwa kuti azithandiza ma crane olemera, makina oyendetsera katundu, ndi zomangamanga zazikulu za m'nyanja zomwe zimakhala zolimba kwambiri m'malo owononga a m'mphepete mwa nyanja.

4. Mphamvu ya Mphepo ya M'nyanja ndi Uinjiniya wa Zam'madzi

Amagwiritsidwa ntchito kwambiri m'mamaziko a ma turbine amphepo a m'mphepete mwa nyanja, mapulatifomu a m'mphepete mwa nyanja, mapaipi a m'nyanja, makoma a nyanja, ndi nyumba zotetezera gombe.Chitoliro chachitsulo cha LSAWMiluyi imapereka mphamvu yolimbana ndi mafunde, mphamvu za mafunde, ndi dzimbiri la madzi a m'nyanja, zomwe zimapangitsa kuti zikhale zoyenera madera ovuta a m'mphepete mwa nyanja.

5. Mapulojekiti Akuluakulu a Uinjiniya Wanyumba

Kulongedza ndi Kutumiza

Phukusi 1:Ma bandeji achitsulo kuti agwire mosavuta. Mabuloko a matabwa kapena dunnage amayikidwa pakati pa milu kuti apewe kusuntha kwa ziwalo panthawi yonyamula. Kukonza pamwamba (ngati mukufuna): Kupaka utoto wakuda, mafuta oletsa dzimbiri, filimu ya pulasitiki. Milu ya galvanized yoviika m'madzi otentha ikhoza kuphimbidwa ndi filimu yoteteza kwakanthawi kuti ipewe kukanda pamwamba. Mapaketi okonzedwa mwamakonda angaperekedwe.

2 Kutumiza:Kutalika kwa katundu wamba: 6m, 12m. Kumapezeka muutali wapadera. Kumabwera ndi Sitima Yapamadzi ndi Msewu Woyenera mayendedwe apanyanja, sitima kapena pamsewu. Nthawi yotumizira nthawi zambiri imakhala masiku 15-30 mutalandira malipiro, kutengera kuchuluka ndi zomwe zafotokozedwa. Yoyenera kutumiza kunja padziko lonse lapansi, yokhala ndi chikalata chokwanira (satifiketi yowunikira, mndandanda wolongedza, bilu yonyamula katundu).

3 Malangizo Othandizira:Musagwiritse ntchito zingwe kapena zingwe zopanda ma pad kuti zigwire ntchito mwachindunji pamwamba pa chitoliro kuti chitolirocho chisawonongeke. Sungani pamalo ozizira, ouma komanso opumira bwino, pewani dzimbiri musanayike. Kutumiza kwakukulu komanso kolemera kwambiri chonde tsatirani malamulo a m'deralo otumizira katundu.

FAQ

1. Kugwiritsa ntchito mapaipi achitsulo a ASTM A252 Giredi 3?

Mapaipi achitsulo a ASTM A252 Giredi 3 LSAW amagwiritsidwa ntchito makamaka pomanga maziko akuya pantchito zomanga, monga nyumba, milatho, madoko, gombe ndi zina zotero.

2. Kodi Giredi 1, Giredi 2 ndi Giredi 3 zimasiyana bwanji?

Imapereka mphamvu yabwino kwambiri komanso kukhazikika kwa magiredi atatu, kotero ndi yabwino kwambiri pa maziko olemera, komanso uinjiniya wapamadzi.

3. Kodi n'chiyaniChubu chachitsulo cha LSAW?

Potengera chidziwitso cha akatswiri pa zitsulo, chitoliro cha LSAW ndi chinthu chopangidwa ndi chitoliro chomwe chimapangidwa pogwiritsa ntchito mbale zachitsulo zopanga ndi zolumikizira za longitudinal, zomwe zimatchedwanso "chitoliro chachitsulo cha longitudinal weld".

4. Kodi pali makulidwe ndi kukula kotani komwe kulipo?

Ma diameter awiri omwe alipo ndi kuyambira OD 406 mm mpaka 2500 mm ndipo makulidwe a khoma ndi kuyambira 6 mm mpaka 60 mm omwe amagwiritsidwa ntchito pomanga maziko olemera ndi ntchito zapamadzi.

5. Kodi ingagwiritsidwe ntchito m'mapulojekiti a m'nyanja ndi m'nyanja?

Inde. Imagwiritsidwa ntchito kwambiri pamagetsi amphepo akunyanja, makoma a m'nyanja, madoko, ndi nsanja za m'nyanja, pakati pa zina. Ili ndi zokutira kuphatikizapo epoxy, 3PE, simenti yoteteza dzimbiri.
