Welded chitoliro, amatchedwanso welded zitsulo chitoliro, kwenikweni wopangidwa ndi mbale zitsulo kapena Mzere welded pambuyo decoiling ndi kupanga.Welded zitsulo chitoliro ali ndi ubwino wa ndondomeko yosavuta kupanga, dzuwa mkulu kupanga, mitundu yambiri ndi specifications, ndi ndalama zochepa zida, koma mphamvu zake zonse ndi otsika kuposa chitoliro chosasokonezeka zitsulo.Kuyambira m'ma 1930, ndi chitukuko mofulumira kupanga apamwamba Mzere anagubuduza kupanga ndi kupita patsogolo luso kuwotcherera ndi luso anayendera, khalidwe la welded msoko wakhala mosalekeza bwino, zosiyanasiyana ndi mfundo za welded zitsulo chitoliro chawonjezeka, ndi zitsulo zopanda msoko. chitoliro chasinthidwa m'minda yambiri.Welded zitsulo mipope anawagawa molunjika msoko welded chitoliro ndi kozungulira welded chitoliro monga mwa mawonekedwe a weld.

一.Gulu la Welded Mipaipi Welded machubu

Mapaipi owotcherera amagawidwa malinga ndi momwe amagwiritsidwira ntchito: amagawidwanso m'mapaipi owotcherera, mapaipi otenthetsera, mapaipi otenthetsera okosijeni, mawaya, mipope yowotcherera, mapaipi opumira, mapaipi amadzi akuya, mapaipi agalimoto, mapaipi osinthira, ma welded woonda. - mipope mipanda, welded matenda mapaipi ndi mipope wozungulira welded.

二.Ntchito Range wa Welded Chitoliro

Welded mankhwala chitoliro chimagwiritsidwa ntchito kukatentha, galimoto, nyumba zombo, kumanga kuwala-kulemera zitseko structural ndi mazenera zitsulo, mipando, zosiyanasiyana zaulimi makina, scaffolding, waya ulusi chitoliro, maalumali mkulu-nyamuka, muli ndi zina zotero. akhoza kukwaniritsa zofunika kasitomala, wapadera abnormal welded chitoliro akhoza kupanga malinga ndi zofuna za wosuta.

三.MFUNDO YOWERENGA NTCHITO YA WEDED PIPE WIGHT  

Pali njira zowerengera kulemera kwa chitoliro chowotcherera.

Theoretical kulemera kwa mita ya chitsulo chitoliro (kachulukidwe zitsulo ndi 7.85 kg/dm3)

Chilinganizo: W = 0.02466 (DS)S

Mu mawerengedwe chilinganizo, ongoyerekeza kulemera kwa W-zitsulo chitoliro pa mita, kg/m;

D - mwadzina m'mimba mwake akunja zitsulo chitoliro, mm;

S - mwadzina khoma makulidwe a chitsulo chitoliro, mm.

四.Tanthauzo Lovomerezeka ndi Kugwiritsa Ntchito Mafakitale a Chitoliro Chowotcherera

Zida zomwe zimagwiritsidwa ntchito pa welded chubu mphero ndi mbale yachitsulo kapena chingwe chachitsulo.Iwo akhoza kugawidwa mu ng'anjo welded chitoliro, magetsi welded chitoliro ndi basi Arc welded chitoliro chifukwa cha luso osiyana kuwotcherera.Malinga ndi mitundu yosiyanasiyana kuwotcherera, zikhoza kugawidwa mu molunjika msoko welded chitoliro ndi kozungulira welded pipe.per mawonekedwe mapeto, zikhoza kugawidwa mu chitoliro wozungulira welded ndi wapadera woboola pakati welded chitoliro (akwere chitoliro lathyathyathya chitoliro etc.) .Mapaipi owotcherera amatha kugawidwa m'magulu otsatirawa malinga ndi zida zawo zosiyanasiyana ndikugwiritsa ntchito:

1. GB/T3091-1993 (Paipi ya Zitsulo Yokhala Ndi Galvanized for Low Pressure Fluid Conveyance)

Amagwiritsidwa ntchito kwambiri potengera madzi, gasi, mpweya, mafuta, kutenthetsa madzi otentha kapena nthunzi ndi madzi ena ambiri otsika kwambiri komanso mapaipi acholinga.Choyimira chake ndi kalasi Q235A chitsulo.

2. GB/T3092-1993 (Paipi ya Zitsulo Yokhala Ndi Galvanized for Low Pressure Fluid Conveyance)

Amagwiritsidwa ntchito kwambiri potengera madzi, gasi, mpweya, mafuta, kutenthetsa madzi otentha kapena nthunzi ndi madzi ena ambiri otsika kwambiri ndi mapaipi acholinga.Zoyimira zake ndi Q235A kalasi yachitsulo.

3. GB/T 14291-1992 (Chitoliro Chowotchedwa cha Mine Fluid Transport)

Amagwiritsidwa ntchito kwambiri pakuthamanga kwa mpweya, ngalande, ngalande yamagetsi ya shaft yokhala ndi chitoliro chowongoka chachitsulo chowongoka.Zoyimira zake ndi kalasi Q235A ndi B chitsulo.GB/T 14980-1994 (Chitoliro Chachitsulo Chachikulu Chachikulu Chachikulu cha Diameter for Low Pressure Fluid Conveyance).Amagwiritsidwa ntchito kwambiri popereka madzi otsika kwambiri monga madzi, zimbudzi, gasi, mpweya, kutentha kwa nthunzi ndi zina.Choyimira chake ndi kalasi Q235A chitsulo.

4. GB/T12770-1991 (Welded zosapanga dzimbiri chitoliro kwa dongosolo makina)

Amagwiritsidwa ntchito makamaka pamakina, magalimoto, njinga, mipando, zokongoletsera hotelo ndi hotelo ndi zida zina zamakina ndi zida zamapangidwe.Zoyimira zake ndi 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.

GB/T12771-1991 (Paipi Yachitsulo Yosapanga dzimbiri ya Fluid Transport)

Amagwiritsidwa ntchito kwambiri pofalitsa zofalitsa zowononga zotsika.

Zida zoyimira ndi 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, ndi zina.
