Ububanzi be-ASTM A53
Imibhobho yentsimbi engenamthungo kunye ne-welded ukusuka kwi-DN 6 ukuya kwi-650 mm enobunzima bodonga ngokwe-ASTM A53 Tables X2.2 kunye ne-X2.3, kunye nemibhobho yentsimbi.
I-ASTM A53 Uhlobo kunye neBanga
Uhlobo lombhobho
Uhlobo F:
I-Furnace Butt-Welded Pipe - Umbhobho odityanisiweyo ngokuqhubekayo.Ivelisa ubude obuninzi bombhobho, othi ke unqunywe ubude bomntu ngamnye kwaye udityaniswe ngoxinzelelo lomatshini oludalwe yimiqulu eshushu.
Qaphela: Uhlobo F alufumaneki ngeeflange
Uhlobo E:
umbhobho wokuxhathisa-welding.Umdibaniso wempundu wexesha elide kubude obunye, okanye kubuninzi bobude obusuka kwingxowa egobileyo, emva koko unqunyulwe kubude obubodwa, ube nomdibaniso wempundu welongitudinal, apho ukudityaniswa kuveliswa bubushushu obuzuzwe kuxhathiso lwangoku kwisekethe apho umbhobho umi, kwaye ngokusetyenziswa koxinzelelo.
Qaphela: Uhlobo E lunikezelwe nokuba alunakwandiswa okanye lubandayo lwandiswa ngokokhetho lomenzi.
Uhlobo S:
Imibhobho engenamthungo - i-Weldless Pipe Joints Iveliswa kwintsimbi eshushu-esebenzayo, ukuba kuyimfuneko, ngokusebenza okubandayo okulandelayo kwemveliso ye-tubula esebenza ngokushushu ukuvelisa ubume obufunwayo, ubungakanani, kunye neempawu.
IQela leBanga
IBakala A:
Eli libakala lesiseko kwaye lilungele ukuhanjiswa koxinzelelo oluphantsi ngokubanzi kunye nolwakhiwo lwezicelo.
IBanga A likhethwa xa imibhobho ifuna ukuqiniswa ngokuqinileyo okanye ukugoba okubandayo.
IBakala B:
Eli linqanaba eliphezulu lamandla okuqina kunye noxinzelelo lokumelana neBanga A kwaye lidla ngokusetyenziswa kwizicelo ezinoxinzelelo oluphezulu.
Ukuphela kwe-ASTM A53
Isiphelo esicaba: uhlobo oluqhelekileyo lokuphela kombhobho alucutshungulwanga, lusebenza kwimfuno yokuqhubela phambili kwimeko.
Isiphelo semisonto: Isiphelo sombhobho sicutshungulwa ngeentambo ukuze kube lula ukudibanisa umbhobho.
Beveled End: Isiphelo sombhobho sifakwe kwi-beveled, kwaye sisetyenziselwa ikakhulu ukudibanisa i-welding.
Izinto ze-ASTM A53 ezikrwada
Isinyithi semibhobho engenamthungo kunye ne-welded kufuneka iveliswe ngenye okanye ngaphezulu kwezi nkqubo:
Isithando somlilo esivulekileyo, iSiko soMbane, okanye iOxygen yealkali.
Unyango lobushushu
Iiwelds ezikwiBanga B Udidi E okanye umbhobho woHlobo luka-F ziya kugalelwa ubushushu emva kokuba zifakwe kwi-welding ubuncinane kwi-1000 F [540°C] ukuze kungabikho martensite enganyangekiyo ekhoyo.
IiMfuno zeMichiza
Iipropati zoomatshini
I-ASTM A53 Olunye uVavanyo
Bend Test
I-DN 50 (NPS 2) okanye encinci: ubude obaneleyo bombhobho buya kukwazi ukugotshwa kubanda nge-90 ° ngeenxa zonke kwi-cylindrical mandrel, ububanzi obuphindwe kalishumi elinesibini buchazwe ngaphandle kwedayamitha yombhobho, ngaphandle kokuphuhlisa iintanda nakweyiphi na indawo kwaye ngaphandle kokuvula. i weld.
Vala ukujiya: umbhobho uya kuma ugotywe ubanda nge-180°ngeenxa zonke i-cylindrical mandrel, ububanzi obuphindwe kasibhozo ngaphandle kwedayamitha echazwe ngaphandle kombhobho, ngaphandle kokusilela.
Umbhobho ophindwe kabini owomeleleyo ngaphezu kwe-DN 32 (NPS 11/4):akukho mfuneko yokuba ifakwe kuvavanyo lokugoba.
Uvavanyo lokucaba
Umbhobho odityanisiweyo ngaphezulu kwe-DN eyi-50 mm kubunzima obunamandla ngakumbi okanye ukhaphukhaphu: iya kuba luvavanyo lokucaba.
Umbhobho ongenamthungo: Akukho vavanyo.
Uvavanyo lweHydrostatic
Umbhobho wesiphelo esicacileyo: Uxinzelelo olusebenzayo ngokweTheyibhile X2.2.
Umbhobho odityanisiweyo kunye noDityanisiweyo: Uxinzelelo olusebenzayo ngokweTheyibhuli X2.3.
Uvavanyo loMbane olungonakaliyo
Ukuba uvavanyo lombane olungonakaliyo lwenziwe, ubude buya kubhalwa ngoonobumba "NDE".
Iigalvanized
I-ASTM A53 Umbhobho ofakwe igalvan uya kugalelwa ngaphakathi nangaphandle ngenkqubo yediphu eshushu.
I-zinc esetyenziselwa ukugquma iya kuba naliphi na ibakala le-zinc elihambelana neNgcaciso ye-B6.Umbhobho wegalvanized uya kukhululeka kwiindawo ezingagqunywanga, amadyungudyungu, iidiphozithi eziqukuqelayo, kunye nokufakwa kwenkunkuma emdaka.Amaqhuma, uqikelelo, iiglobhu, okanye iidiphozithi ezinzima ze-zinc eziya kuphazamisana nokusetyenziswa okucetyiweyo kwezixhobo aziyi kuvunyelwa.
Umphezulu wombhobho wentsimbi uya kuba netyabeka ye-zinc engekho ngaphantsi kwe-0.40 kg/m² ngokubala ubunzima kunye nommandla wengubo yegalvanized.
