Kodi Chitoliro cha Ndondomeko 40 Chili Choyenera Kugwiritsa Ntchito Kapangidwe ka Nyumba?

Kufufuza Kufunika kwa SCH 40 mu Kumanga Zitsulo

Chitoliro cha Schedule 40 nthawi zambiri chimavomerezedwa ngati chogwiritsidwa ntchito mobwerezabwereza komanso chosinthika kwambirimawonekedwe a echitoliro chachitsulo cha kabonimu gawo la zitsulo.Komabe, funso limabuka pakati pa mainjiniya, ogula, ndi omanga: Kodi chitoliro cha Schedule 40 chili choyenera kugwiritsidwa ntchito pomanga nyumba?

Nkhaniyi ifufuza momwe Ndandanda 40 imagwirira ntchito komanso kufunika kwake m'makonzedwe ake.

Kumvetsa chomwe chiri "Ndandanda 40"
Ndondomeko 40 sikutanthauza mtundu wa zinthu kapena mphamvu yake—imatanthauza makulidwe a khoma la chitoliro chomwe chimatsatiraASME/ASTMmalangizo a magawo.

Kuchokera patebulo lomwe tikuona, chitoliro cha mainchesi awiri cha Schedule 40 chili ndi makulidwe a khoma a 3.91 mm, pomwe chitoliro cha mainchesi 8 chimakhala ndi 8.18 mm. Miyeso iyi imayesedwa ndi ASME B36.10M, makamaka yopangidwira mapaipi opanikizika mumakina otumizira madzi.

Yopangidwira Kupanikizika, Osati Katundu Wopangidwa

Mapaipi a Schedule 40 nthawi zambiri amapangidwa motsatira miyezo monga ASTM A53, ASTM A106, kapenaAPI 5LMafotokozedwe awa akugogomezera kusunga mphamvu, kusinthasintha, komanso kukana dzimbiri, osati mphamvu ya kapangidwe kake.

Izi zikutanthauza kuti mapaipiwa adapangidwa kuti athe kupirira kupsinjika kwamkati, osati mphamvu zakunja monga kupindika kapena kupsinjika m'mapangidwe a nyumba.

Kodi Kugwiritsa Ntchito Kapangidwe Kake N'kotheka?

Inde—ngakhale ndi malamulo ena.

Chitoliro cha Schedule 40 chingagwiritsidwe ntchito pamapulojekiti opepuka kapena osafunikira kwenikweni, makamaka pazinthu monga:

- Zotchingira, mpanda, ndi zogwirira

- Mafelemu othandizira ndi mashelufu

- Zikwangwani ndi ma truss ang'onoang'ono

Muzochitika izi, Ndandanda 40 ndi njira yotsika mtengo chifukwa cha mphamvu yake yokwanira yogwiritsira ntchito zinthu zosafunikira komanso kupezeka kwake kulikonse.

Komabe, tikasankha zinthu za nyumba zonyamula katundu kapena zigawo zina mkati mwa mapangidwe ovomerezeka aukadaulo ndi kapangidwe kake, mapaipi achitsulo apamwamba monga ASTM A500 kapena ASTM A252 ayenera kusankhidwa m'malo mwake. Chifukwa izi zimapangidwa makamaka kuti zikhale bwino ndipo zimayesedwa magwiridwe antchito amakina.

Kuyerekeza Ndandanda 40 ndi ASTM A500 Structural Tubing

Monga momwe tebulo likusonyezera, pamene pakufunika mphamvuh, kulolerana kofanana, komanso magwiridwe antchito nthawi zonse mukanyamula katundu, chisankho chabwino ndi ASTM A500.

Maganizo Omaliza

Ndondomeko ya mapaipi 40 ikupitiriraNdi imodzi mwa mitundu ya mapaipi achitsulo omwe amagwiritsidwa ntchito kwambiri komanso otsika mtengo omwe alipo. Imagwira bwino ntchito zamadzimadzi, kupanga zinthu zambiri, komanso ntchito zopepuka.

Komabe, ndikofunikira kusankha chitoliro chovomerezeka chachitsulo kapena mapaipi (monga ASTM A500 kapena A252) pamapulojekiti omwe amafunikira kudalirika kwa kapangidwe kake.

Izi sizikutsimikizira kokha kutsatira malamulo opangidwa, komanso chitetezo cha nthawi yayitali komanso magwiridwe antchito a polojekiti yanu.

TianjinYuantai DerunSteel Pipe Group ndi kampani yodalirika yopereka mapaipi achitsulo a Schedule 40 ndi machubu omangira a ASTM A500, yomwe imapereka zinthu zonse komanso satifiketi yoyesera mphero kwa makasitomala otumiza kunja padziko lonse lapansi.

Kuti mudziwe zambiri kapena mafunso, chonde funsani—gulu lathu laukadaulo lilipo kuti likuthandizeni kusankha chitsulo choyenera chomwe mukufuna.
