I-ASTM i-A53 ye-Structural Steel Pipe

I-ASTM A53 yoMbhobho weStructural Steel obonakalayo

Inkcazelo emfutshane:

Umbhobho we-ASTM A53 (okwaziwa ngokuba ngumbhobho we-ASME SA53) usetyenziselwa ukusetyenziswa koomatshini kunye noxinzelelo kwaye unokusetyenziselwa iinjongo eziqhelekileyo zomphunga, amanzi, igesi kunye nemibhobho yomoya.

Iityhubhu zentsimbi ezingenamthungo kwiiNjongo zoLwakhiwo, iiThubhu zetsimbi ezingenamthungo kwiiMechanical Structures kwi-GB/8162-2008 Standard.Izinto eziphathekayo zibandakanya i-High-Quality Carbon Steel kunye ne-Low Alloy Steel, njenge-10,20,35,45 kunye ne-Q345, Q460, Q490,42CrMo, 35CrMo.

Isicelo: Ukusetyenziswa koomatshini kunye noxinzelelo, kunye nokuhambisa umphunga, amanzi, igesi, njl.

Isicelo

Ukusetyenziswa koomatshini kunye noxinzelelo, kunye nokuthutha umphunga, amanzi, igesi kunye njl.

Izatifikethi zovavanyo lweMill ziya kukhutshwa ngokwe-EN10204/3.1B.

Umbhobho we-ASTM A53 (ekwabizwa ngokuba ngumbhobho we-ASME SA53) wenzelwe ukusetyenziswa koomatshini kunye noxinzelelo kwaye wamkelekile ukusetyenziswa okuqhelekileyo kumoya, amanzi, igesi, kunye neentambo zomoya.Ifanelekile kwi-welding, kwaye ifanelekile ukwenza imisebenzi ebandakanya ukujiya, ukugoba, kunye ne-flanging, ngokuxhomekeke kwiziqinisekiso ezithile.

Izixhobo kunye nokuVeliswa

Intsimbi yomibini ipayipi engenamthungo kunye ne-welded iya kwenziwa yinye okanye ngaphezulu kwezi nkqubo zilandelayo: i-open-hearth, i-furnace yombane, okanye i-basic-oxygen.Umthungo odityanisiweyo wombhobho odityanisiweyo wokumelana nombane kwiBanga B uya kunyangwa ngobushushu emva kwewelding.

Izicelo: abatshintshi bokushisa, i-condensers, izixhobo zokufudumeza ukushisa kunye nemibhobho efanayo.

I-A53 yeBanga B Umbhobho wentsimbi engenamthungo yeyona mveliso yethu yencam yomhlaba phantsi kolu balulo kwaye umbhobho we-A53 ukholisa ukuqinisekiswa kabini ukuya kwi-A106 B umbhobho ongenamthungo.

Umbhobho we-A53 uza kwiindidi ezintathu (F, E, S) kunye namabanga amabini (A, B).

I-A53 Uhlobo E lune-weld yokumelana nombane (iBanga A kunye no-B).

I-A53 Uhlobo S ngumbhobho ongenamthungo kwaye ufumaneka kumaBanga A no-B).

I-A53 Uhlobo lwe-F lwenziwe nge-weld yesithando somlilo okanye lunokuba ne-weld eqhubekayo (iBanga A kuphela).

Ukupakisha

Ukupakisha okungenanto / ukupakishwa kwebhandle / ukupakishwa kwekhreyithi / ukukhuselwa komthi kumacala omabini eityhubhu kwaye ikhuselwe ngokufanelekileyo ukuhanjiswa okufanelekileyo elwandle okanye njengoko kuceliwe.

Zombini iziphelo ityhubhu nganye ziya kubonisa umyalelo no., Ubushushu hayi., imilinganiselo, ubunzima kunye neenyanda okanye njengoko kuceliwe.
