Ukusetyenziswa okuqhelekileyo kwezinto zokufaka iipayipi

Intsimbi yeCarbon engaphantsi kobushushu obuphantsi Iingqengqelo ezingenamthungo

Zenzelwe inkonzo ebalulekileyo kwiindawo ezishushu kakhulu nezinobushushu obuphantsi, ii-Carbon Steel Low-Temperature Seamless Elbows zethu zenziwe ngezinto ezikumgangatho ophezulu ezifana ne-API 5L X65 okanye intsimbi ekhethekileyo ye-ASTM A333 Grade 6. Zifumaneka kuzo zombini ii-configurations ze-90° kunye ne-180° ezine-standard 1.5D Long Radius, ezi ngqiniba ze-butt weld zenzelwe ukugcina ukuqina okugqwesileyo kunye nokuqina kwesakhiwo phantsi kweemeko ezingaphantsi kwe-zero, ukuthintela ukwaphuka okubuthathaka kwizicelo ezifana nokucubungula i-LNG, ukugcinwa kwe-cryogenic, kunye neenkqubo zepayipi ze-arctic.

Zenziwe ngenkqubo yokwenza ubushushu engenamthungo, ezi ngqiniba zibonelela ngokuqhubekeka okuphezulu kwe-metallurgical kunye nokuthembeka koxinzelelo xa kuthelekiswa nezinye ezidityanisiweyo. I-radius yokugoba ye-1.5D iqinisekisa ukuhamba kakuhle kunye nokuxinana okuncinci kunye nokwehla koxinzelelo, ngelixa ukulungiswa kwe-weld bevel echanekileyo kuqinisekisa ukujija kwentsimi esemgangathweni ophezulu, egcweleyo. Ezi zixhobo zikhetho oluthembekileyo lweenjineli eziyila iinkqubo zepayipi ezikhuselekileyo nezihlala ixesha elide ekufuneka zisebenze ngokuthembekileyo ukusuka kwindawo engqongileyo ukuya kumaqondo obushushu abandayo.

I-PIPE TEE ISINCIPHI SOKUNCIPHISA IMIBHAWU Isiciko sepayipi I-PIPE BEND IZIXHOBO EZIQINISEKISIWEYO

I-BUTT WLDED PIPE ELBOW

Ingqiniba yentsimbi yinxenye ebalulekileyo kwinkqubo yemibhobho yokutshintsha indlela ukuhamba kolwelo. Isetyenziselwa ukudibanisa imibhobho emibini enobubanzi obufanayo okanye obahlukeneyo, nokwenza umbhobho ujike uye kwicala elithile le-45 degrees okanye i-90 degrees.

Kwi-industrial pipe elbow, uhlobo lwe-connectin end yi-butt weld, ngokwe-ANSI B16.25. I-butt weld ingachazwa njenge-butt welding, i-buttweld, kunye ne-bevel end. BW

UHLOBO LWESIBANDLA

Ingqiniba inokubalwa ukusuka kwikona yecala, iintlobo zoqhagamshelo, ubude kunye nerediyasi, kunye neentlobo zezinto.

Ihlelwe ngokwe-Direction Angle

Njengoko sisazi, ngokwendlela oluhamba ngayo ulwelo lwemibhobho, ingqiniba inokwahlulwa ibe ziidigri ezahlukeneyo, ezifana needigri ezingama-45, iidigri ezingama-90, iidigri ezili-180, ezizezona ziqhelekileyo. Kwakhona kukho iidigri ezingama-60 kunye needigri ezili-120, kwezinye iipayipi ezikhethekileyo.

Kwingqiniba yeedigri ezingama-90, kuchazwe nengqiniba yeedigri ezingama-90, okanye ingqiniba yeedigri ezingama-90.

Yintoni i-Elbow Radius

Irediyasi yengqiniba ithetha irediyasi egobileyo. Ukuba irediyasi ifana nobubanzi bombhobho, ibizwa ngokuba yi-short radius elbow, ekwabizwa ngokuba yi-SR elbow, ngokuqhelekileyo kwiipayipi eziphantsi koxinzelelo kunye nesantya esiphantsi.

Ukuba i-radius inkulu kunobubanzi bombhobho, i-R ≥ 1.5 Diameter, ngoko siyibiza ngokuba yi-long radius elbow (LR Elbow), esetyenziselwa imibhobho yoxinzelelo oluphezulu kunye nesantya sokuhamba kwamanzi esiphezulu.

Ukuba i-radius ingaphezulu kwe-1.5D, soloko ibizwa ngokuba yi-bend. I-elbow bend pipe fittings. Ezifana ne-2d elbow, i-2d bend, i-3d elbow, i-3d bend, njl.

Uhlulo ngokwezinto eziphathekayo

Intsimbi yekhabhoni, ekwabizwa ngokuba yintsimbi ethambileyo okanye intsimbi emnyama. Njenge-ASTM A234 WPB

UMPHEZULU WE-ELBOW

Ukuqhuma kweSand

Emva kokwenza ubushushu, silungiselela ukuqhuma kwesanti ukuze umphezulu ucoceke kwaye uthambe.

Emva kokuqhuma kweSand, ukuze kuthintelwe ukugqwala, kufuneka upeyinte ngomnyama okanye ngeoyile yokulwa nomhlwa, i-Hot dip galvanized (HDG), i-epoxy, i-3PE, umphezulu onyamaleleyo, njl. Oko kuxhomekeke kwisicelo somthengi.

Izinto kunye neMetallurgy:
Iingqiniba zenziwe ngepayipi engenamthungo eqinisekisiweyo kwi-API 5L X65 ukuze zisetyenziswe ngamandla aphezulu okanye kwi-ASTM A333 Grade 6 ukuze zifumane iimpawu eziqinisekisiweyo zokuchaphazela ubushushu obuphantsi. Ezi ntsimbi zicociwe kakuhle, zifile ngokupheleleyo, kwaye zihlala zilungelelaniswa ukuze kufezekiswe amaxabiso afunekayo e-Charpy V-Notch (CVN) impembelelo kubushushu obuncinci obuchaziweyo. Ikhemistri ilawulwa ukunciphisa izinto ezikhuthaza ukuqhekeka, ukuqinisekisa ukuqina okugqwesileyo kokuqhekeka kwiindawo ezibandayo.

Inkqubo Yokuvelisa Engenamthungo:
Iingqiniba zenziwa ngokusebenzisa ukugoba okushushu okulawulwayo kombhobho ongenamthungo okanye inkqubo yokutyhala eshushu. Zombini ezi ndlela zigcina ukulingana kwezinto ngaphandle kokudala umthungo othe tyaba. Emva kokwakheka, iingqiniba zifumana unyango lobushushu oluqhelekileyo ukuze kuphuculwe isakhiwo sengqolowa, kuncitshiswe uxinzelelo, kwaye kubuyiselwe iimpawu zoomatshini ezibalulekileyo ekusebenzeni kobushushu obuphantsi.

Ubunjineli obuchanekileyo kunye nobukhulu:
Yenziwe ngokungqongqo ngokwemilinganiselo ye-ASME B16.9.

Ubukhulu obuvela embindini ukuya ekupheleni/phakathi ukuya embindini: Ilawulwa ngokuchanekileyo ukuze kube noyilo oluchanekileyo lwemibhobho.

Ulawulo loBungqingqwa boDonga: Le nkqubo iqinisekisa ubungqingqwa obufanayo. Ingqwalasela ekhethekileyo inikwa kwi-extrados (igophe langaphandle) ukuze kugcinwe ukuncitshiswa ngaphakathi kwemida evumelekileyo ye-ASME B16.9 (ngesiqhelo i-12.5%).

Ukungabi nasiphako kunye neBevel: Iziphelo zenziwe ngomatshini ukuqinisekisa ukuba zijikelezile ukuze zilingane kakuhle. Ibevel yokuwelda ye-37.5° ehambelanayo enomhlaba we-1.6mm ilungiselelwe kuzo zombini iziphelo.

Ukumakisha kunye nokulandeleka:
Ingqiniba nganye igximfizwa ngokusisigxina ngokwe-ASTM A960, kuquka: Iinkcukacha zezinto (umz., i-API 5L X65 okanye i-A333 Gr.6), Inombolo yobushushu, ubungakanani, ishedyuli yodonga, isazisi somenzi, kunye nesichazi-magama "se-LT" (ubushushu obuphantsi). Oku kuqinisekisa ukulandeleka ngokupheleleyo ukusuka kwindawo yokugaya intsimbi ukuya kwimveliso egqityiweyo.

UNYANGO LOBUSHUSHU

1. Gcina isampuli yezinto ezikrwada ukuze zilandelelwe.
2. Lungiselela unyango lobushushu ngokwemigangatho emiselweyo.

UKUPHAWULA

Imisebenzi eyahlukeneyo yokumakisha, inokugoba, ipeyintwe, ibhalwe ilebhile. Okanye xa ucela. Siyamkela ukumaka iLOGO yakho.

IIFOWUNI EZINIKA INKCAZELO

1. Isiphelo se-Bevel ngokwe-ANSI B16.25.

2. Ukuqala ngokuqhumisa isanti, uze emva koko upeyinte kakuhle. Ingafakwa ivarnish.

3. Ngaphandle kwe-lamination kunye neentanda.

4. Ngaphandle kokulungiswa kwe-weld.

UVAVANYO

Ubushushu ngabunye bentsimbi bunikwa iSatifikethi soVavanyo lweMill esipheleleyo (MTC 3.2) esichaza ikhemistri kunye neempawu zoomatshini. Senza uVavanyo lweMpahla oluQinisekileyo (PMI) kunye nokuhlolwa kobukhulu be-ultrasonic kumbhobho oluhlaza. Uqinisekiso oluphambili yiCharpy V-Notch Impact Testing ngokwe-ASTM A370. Iiseti zeesampuli ezintathu zivavanywa kubushushu obuncinci boyilo (umz., -46°C) ukuqinisekisa ukuba amandla afunxwayo ayahlangabezana okanye adlula iimfuno ezichaziweyo (umz., ≥ 20J okanye 27J ngokwe-ASTM A333).

UKUPAKISHA NOKUTHUMELA

Ukuthintela ukugqwala ngexesha lokuhamba, iziphelo ezijijekileyo kunye neendawo eziveziweyo zigqunywa ngesixhobo sokuthintela ukugqwala sexesha elifutshane nesisuswa lula. Ingqiniba nganye emva koko isongelwe ngefilimu ye-VCI (Vapor Corrosion Inhibitor) okanye iplastiki enzima. Kwiingqiniba ezinzima okanye ezinkulu, ii-cradles zomthi okanye iikreyithi ezenziwe ngokwezifiso zisetyenziselwa ukubonelela ngenkxaso yesakhiwo kunye nokuthintela ukuguguleka.

Sisebenzisa iindlela ezahlukeneyo ngokusekelwe kubungakanani beodolo kunye nokungxamiseka: ukuthunyelwa ngenqwelo moya kwezinto ezibalulekileyo ezikhawulezileyo, isikhongozeli solwandle (i-FCL/LCL) see-odolo ezinkulu, kunye nezikhongozeli ezisicaba zeengqiniba ezinkulu. Onke amaxwebhu okuthumela (Uluhlu lokuPakisha, i-invoyisi yoRhwebo, iSatifikethi seMvelaphi, kunye nePakeji epheleleyo yoVavanyo) zilungiselelwe ukwenza kube lula ukususwa kwempahla kwiiprojekthi zoshishino kwihlabathi liphela.
