Umda we-ASTM A106 kunye ne-ASTM A53:
Ukucaciswa kwe-ASTM A53 kugubungela iintlobo zokwenziwa kombhobho wentsimbi ngokungenamthungo kunye ne-welded, izinto zentsimbi yekhabhoni, intsimbi emnyama.Umphezulu wendalo, omnyama, kunye nobushushu obufakwe kwigalvanized, umbhobho wentsimbi oqatywe ngezinki.Ububanzi buvela kwi-NPS 1⁄8 ukuya kwi-NPS 26 (10.3mm ukuya kwi-660mm), ubukhulu bodonga lwegama.
Iimpawu eziqhelekileyo zeASTM A106 zibandakanyacarbon ingenamthungo umbhobho steel, isicelo seenkonzo zobushushu obuphezulu.
Iindidi ezahlukeneyo kunye namabanga kuyo yomibini imigangatho:
Kwi-ASTM A53 kukho i-ERW kunye nemibhobho yentsimbi engenamthungo Uhlobo F, E, S lugubungela iBanga A kunye no-B.
I-A53 Uhlobo F, i-furnace butt edityanisiweyo, i-weld eqhubekayo iBanga A
I-A53 Uhlobo lwe-E, i-Electric resistance welded (ERW), kwiBanga A kunye neBanga B.
I-A53 Uhlobo lwe-S, umbhobho wensimbi ongenamthungo, kwiBanga A kunye neBanga B.
Ukuba izinto zentsimbi ekrwada zamabakala ahlukeneyo kwinkqubo yokuphosa ngokuqhubekayo, umphumo wezinto eziguqukayo uya kuchongwa.Kwaye umenzi kufuneka asuse imathiriyeli yenguqu kunye neenkqubo ezinokuhlula amabanga ngokufanelekileyo.
Kwimeko ye-ASTM A53 yeBanga B kwi-ERW (i-electric resistance welded) umbhobho, i-weld seam iya kwenziwa unyango lobushushu nge-1000 ° F [540 ° C] ubuncinane.Ngale ndlela akukho martensite engapheliyo ihlala.
Kwimeko apho umbhobho we-ASTM A53 B kubanda wandiswa, ngoko ukwandiswa akufanele kudlule i-1.5% ye-OD efunekayo.
Kwi-ASTM A106 yensimbi yombhobho, ukuvelisa Uhlobo kuphela kwi-seamless, iinkqubo ezishushu ziqengqiwe kunye nokubanda.IBanga ku-A, B no-C.
I-ASTM A106 iBanga A: Ubuninzi beCarbon element 0.25%, Mn 0.27-0.93%.Ubuncinci bokuqina kwamandla 48000 Psi okanye 330 Mpa, isivuno amandla 30000 Psi okanye 205 Mpa.
A106 IBakala B: Ubuninzi C ngaphantsi kwe-0.30%, Mn 0.29-1.06%.Ubuncinci bokuqina kwamandla 60000 Psi okanye 415 Mpa, isivuno amandla 35000 Psi okanye 240 Mpa.
IBakala C: Ubuninzi C 0.35%, Mn 0.29-1.06%.Ubuncinci bokuqina kwamandla 70000 Psi okanye 485 Mpa, isivuno amandla 40000 Psi okanye 275 Mpa.
Ngokwahlukileyo ngeI-ASTM A53 GR.B imibhobho yentsimbi engenamthungo,I-ASTM A106 GR.B imibhobho yentsimbi engenamthungoine-Si min 0.1%, apho i-A53 B ine-0, ngoko ke i-A106 B inokumelana nobushushu obungcono kune-A53 B, ekubeni i-Si iphucula ukuxhathisa ubushushu.
Iindawo zokusetyenziswa kuzo zombini:
Yomibini le mibhobho ifake izicelo kumatshini kunye neenkqubo zoxinzelelo, ukuthutha umphunga, amanzi, igesi, njalo njalo.
Ukusetyenziswa kombhobho we-ASTM A53:
1. Ukwakhiwa, ukuthutha ngaphantsi komhlaba, ukukhutshwa kwamanzi aphantsi komhlaba ngelixa kwakhiwa, ukuthuthwa kwamanzi e-steam njl.
2. Iiseti zokuthwala, ukusetyenzwa kwamacandelo oomatshini.
3. Ukusetyenziswa kombane: Ukuhanjiswa kwerhasi, umbhobho wolwelo lokuvelisa umbane wamanzi.
4. Isityalo samandla omoya ityhubhu ye-anti-static njl.
5. Imibhobho efuna i-zinc coated.
Ukusetyenziswa kombhobho we-ASTM A106:
Ngokukodwa kwiinkonzo zobushushu obuphezulu ukuya kuthi ga kwi-750 ° F, kwaye inokuthatha indawo yombhobho we-ASTM A53 kwiimeko ezininzi.Kwelinye ilizwe ubuncinci e-United States, i-ASTM A53 yeyombhobho odityanisiweyo ngelixa i-ASTM A106 yeyemibhobho yentsimbi engenamthungo.Kwaye ukuba umxhasi ucele i-ASTM A53 baya kubonelela nge-ASTM A106.E-China, umenzi uya kunika umbhobho ohambelana nemigangatho emithathu ye-ASTM A53 GR.B/ASTM A106 GR.B/API 5L GR.B imibhobho yentsimbi engenamthungo.
