Product Overview
Bolted pob qij txha poob ntawm cov txiv ntoo ntau npaum li ntawm lub pob. ASTM A194 2H txiv ntseej yog cov txiv ntoo ib nrab ntawm tus qauv B7 / 2H bolting khub siv rau ntawm flanged pob qij txha hauv refineries, petrochemical nroj tsuag, fais fab mov thiab tshav kub exchangers - tshav kub-kho, hnyav hex, thiab ua kom coj tib lub load thiab kub lub stud pom.
Peb muab 2H hnyav hex txiv ntseej los ntawm 1/2 "mus rau 4" hauv UNC thiab 8UN threads, tiaj los yog kub-dip galvanized, nrog 2HM muaj raws li qaub- kev pabcuam txawv. Lawv tau ua kom phim peb cov ASTM A193 B7 stud bolts, vim tias ob leeg tau yuav ua ke thiab yuav tsum tau muab ua ke.
Kennen Steel International Co., Ltd. yog Tuam Tshoj -raws li steel trading tuam txhab thiab thawj tus neeg sawv cev tier mills. Peb tsis khiav ib lub Hoobkas - peb yuav ncaj qha los ntawm vetted qhov chaw mills, tuav lawv rau cov specification koj pom zoo, thiab tswj cov export sab kawg kom kawg. Peb lub xyoos ntawm kev lag luam steel nyob rau hauv Suav teb thiab ib tug vetted network ntawm qhov chaw mills yog dab tsi sawv tom qab txhua qhov kev txiav txim.
Feem ntau ntawm peb cov txiv ntoo xa mus rau MRO distributors, valve thiab flange cov tub luam, thiab cov neeg cog qoob loo thoob plaws Africa, Middle East thiab Southeast Asia - cov neeg yuav khoom uas xaj cov txiv ntoo thiab txiv ntoo ua ib kab khoom thiab xav tau qib, qhov sib tw thiab cov ntaub ntawv ua haujlwm.
Qhov Zoo Tshaj Plaws
Direct mill mov, tsis yog ib qho khoom muag
Peb yuav los ntawm cov mills thiab peb tshuaj xyuas qhov lawv ua. Qib stamped ntawm cov txiv ntseej yog qib hauv lub thawv, thiab yog tias ib pawg tsis tau raws li qhov kev pom zoo, nws yuav tsis xa. Koj tau txais zeb zoo nrog ib tus neeg lav ris rau qhov kev txiav txim.
Matched rau B7 studs ua ib khub bolting
A 2H txiv ntseej yog teev ua ke nrog A193 B7 stud, tsis xaiv ntawm nws tus kheej - khub ua haujlwm raws li qhov system. Peb muab ob qho tib si, yog li cov xov series, qib thiab tiav match thiab koj tsis chasing ib tug sib xws txiv ntseej tom qab lub studs av.
Thaum tshav kub kub- kho rau siab - qhov kub thiab txias
2H yog qib txiv ntseej uas mus nrog B7 hauv siab - kub, siab - cov pob qij txha. Nws yog cua sov-kho cov pa roj carbon steel rau ASTM A194 2H, nrog rau qhov hardness thiab cov khoom rau lub tshav kub tau lees paub ntawm daim ntawv pov thawj zeb kuaj ntau dua li kev ntseeg siab.
Hex hex, me me rau txoj haujlwm
Hnyav hex qhov ntev ua raws li ASME B18.2.2, uas muab ntau qhov kabmob thiab phab ntsa tuab dua li tus qauv hex txiv ntoo - txoj cai rau flange stud nyob rau hauv load. Qhov ntau thiab tsawg khiav 1/2 "mus rau 4", yog li cov txiv ntoo sib tw nrog lub stud yam tsis muaj adapter.
Cov xov uas sib xyaw nrog koj cov kav dej spec
UNC ua txhua hnub imperial series; 8UN qhov twg qhov loj dua hu rau nws. Qhia rau peb cov kab spec thiab peb yuav muab cov xov series nws xav tias.
Plain los yog kub -dip galvanized
Plain (dub) rau qhov siab li ib txwm -kev pabcuam kub, kub-dip galvanized qhov chaw sib koom pom sab nraum zoov lossis huab cua raug. Kev xaiv txheej yog qhov kev txiav txim siab spec - qhia peb txog qhov kev pabcuam thiab peb yuav lees paub qhov haum.
2HM muaj rau kev pabcuam qaub
Qhov twg cov kab ntub dej H2S, 2HM rau NACE MR0175 tej zaum yuav yog cov txiv ntoo uas tau teev tseg es tsis yog 2H dawb, nrog kev tswj nruj dua. Peb tuaj yeem hais nws raws li qhov sib txawv ntawm - muaj thiab cov ntaub ntawv raug lees paub rau ib qho kev txiav txim.
Cov ntaub ntawv uas tshem lub rooj vag
Ib daim ntawv pov thawj EN 10204 3.1 zeb xeem ib pob los ua tus qauv, kev tshuaj xyuas qhov ntev yog khiav mus rau tus qauv raug suav, thib peb- kev tshuaj xyuas tog tuaj yeem npaj tau raws li kev thov, thiab peb txhawb nqa cov ntaub ntawv ua raws li qhov chaw uas qee lub khw xav tau, xws li KEBS lossis PVoC.

FAQ
ASTM A194 2H txiv ntseej siv rau dab tsi?
Nws yog cov txiv ntoo rau siab - kub thiab siab - siab bolted pob qij txha - flanged kev sib txuas hauv refineries, petrochemical nroj tsuag, chaw nres tsheb fais fab thiab cov khoom siv hluav taws xob. A194 2H yog qib txiv ntseej uas ua ke nrog A193 B7 stud, yog li qhov twg cov kav dej spec hais tias B7, nws ib txwm hais tias 2H nrog nws.
Dab tsi yog qhov txawv ntawm 2H txiv ntseej thiab tus qauv hex txiv ntoo?
A 2H txiv ntseej yog ib qho hnyav hex txiv ntoo - tuab thiab loj dua thoob plaws lub tiaj tiaj dua li tus qauv hex txiv ntseej, raws li ASME B18.2.2 - thiab nws yog cua sov- kho cov pa roj carbon steel rau qib uas tau hais tseg (ASTM A194 2H) es tsis yog qhov dav dav - cov txiv ntseej. Nws tau tsim los nqa lub nra ntawm B7 flange stud ntawm qhov kub thiab txias, uas ib qho zoo tib yam hex txiv ntoo tsis tau teev tseg rau.
Qhov txawv ntawm 2H thiab 2HM yog dab tsi?
2H yog tus qauv txiv ntseej qib rau B7 bolting . 2HM yog qhov txawv rau kev pabcuam qaub, teev rau NACE MR0175, nrog qis dua thiab nruj zog txwv. Yog tias txoj kab tuav H2S ntub dej, koj qhov spec feem ntau yuav hais 2HM. Peb tuaj yeem muab nws raws li qhov sib txawv ntawm - qhia peb txog kev pabcuam thiab peb yuav paub meej tias muaj thiab cov ntaub ntawv.
Cov txiv ntoo puas tuaj nrog studs?
Yog lawm. Peb muab cov txiv ntseej no sib tw rau peb ASTM A193 B7 stud bolts, txij li ob qho tib si yog ib qho system thiab feem ntau txiav txim ua ke. Qhia rau peb cov stud loj thiab xov series thiab peb yuav muab qhov sib txuam 2H txiv ntseej ua ib kab.
Kuv puas yuav tsum siv UNC lossis 8UN xov?
UNC yog txhua hnub imperial series; 8UN yog ib qho ntawm qhov loj dua thiab qhov twg cov kav dej spec hu rau nws. Nws yog kev txiav txim siab spec, tsis yog qhov nyiam - xa peb cov kab specification thiab peb yuav muab cov koob nws xav tau.
Kuv yuav xaiv qhov twg tiav?
Plain (dub) rau qhov siab li ib txwm -kev pabcuam kub, kub-dip galvanized qhov chaw sib koom pom sab nraum zoov lossis huab cua raug. Kev xaiv tiav yog nyob ntawm qhov chaw pabcuam - qhia peb qhov kev sib koom ua ke mus thiab peb yuav lees paub qhov haum.
Cov txiv ntoo ua tau zoo li cas?
Hardness yog ib ASTM A194 2H, nrog rau qhov tseeb ntau yam rau koj batch teev nyob rau hauv daim ntawv pov thawj zeb xeem. Peb hais daim ntawv pov thawj es tsis yog daim ntawv qhia tus lej, thiab rau 2HM qhov kev tswj nruj dua uas qib yuav tsum tau txheeb xyuas tib yam.
Koj puas muab daim ntawv pov thawj kuaj thiab tshuaj xyuas?
Yog lawm. Txhua batch nkoj nrog EN 10204 3.1 daim ntawv pov thawj zeb xeem suav nrog cov lus pom zoo. Thib peb-kev soj ntsuam tog (SGS, BV, Intertek) tuaj yeem npaj tau raws li kev thov, thiab peb tuaj yeem txhawb nqa cov ntaub ntawv ua raws li qhov chaw xws li KEBS lossis PVoC qhov twg koj lub lag luam xav tau.
Koj puas tuaj yeem muab cov khoom tsis yog - qhov loj me lossis ib daim ntawv xov xwm tshwj xeeb?
Heavy hex ceev khiav 1/2 "mus rau 4" (M12-M100) raws li tus qauv. Xa peb qhov loj me, xov series thiab ua tiav los ntawm koj cov piping spec thiab peb mam li paub meej ua ntej koj cog lus.
Koj puas yog tus tsim khoom?
Tsis yog. Peb yog Tuam Tshoj -raws li steel trading tuam txhab thiab thawj -tier mill tus neeg sawv cev. Peb yuav ncaj qha los ntawm vetted qhov chaw mills, txheeb xyuas qib thiab qhov ntev, thiab tswj kev xa tawm - tiav, ntim, ntawv pov thawj thiab xa khoom. Koj tau txais zeb zoo nrog ib tus neeg lav ris rau qhov kev txiav txim.
