IB , Basic structural sib txawv
1. Ob chav End Stud(Double-Ended Stud / Equal Thread Stud)
- Structure: Xov tsuas yog ntawm ob kawg, du unthreaded shank nyob rau hauv nruab nrab, tsis muaj taub hau
- Txuj: GB/T 901, ASME B18.31.2 Ob chav End Hom
- Feature: Tsau tuav ntev txiav txim siab los ntawm cov shank dawb; tsis tuaj yeem kho clamping ntau yam ywj pheej
2. Fully Threaded Stud(Nruam xov Stud / Tag Nrho Xov Stud Bolt)
- Structure: Tag nrho cov pas nrig npog los ntawm cov xov tsis sib xws, xoom du shank los ntawm qhov kawg mus rau qhov kawg
- Txuj: HG/T 20613, GB/T 9125, ASME B18.31.2 Nruam Xov Hom
- Feature: Adjustable clamping ntev; phim txawv flange thickness, ntau- txheej gaskets
2, Kev sib piv ntawm cov qauv thiab cov khoom siv
3, Mechanical Performance & Stress Feature
1. Ob Chav End Stud
- Kev ntxhov siab muaj nyob ntawm cov xov -shank hloov; yooj yim qaug zog tsis ua hauj lwm nyob rau hauv cyclic vibration
- Plain shank txwv elastic deformation; tsis zoo los tiv thaiv- creep kev ua haujlwm nyob rau hauv qhov kub siab ntev
- Tsuas yog ob lub xov tooj xwb bears load, tsis sib npaug zog faib
2. Tag Nrho Threaded Stud
- Tsis muaj kev hloov pauv ntawm lub shank nrawm, tsis sib xws kev ntxhov siab faib raws tag nrho ntev
- Muaj zog tiv thaiv- qaug zog & tiv thaiv- kev ua haujlwm nkag, ruaj khov ua ntej- zawm quab yuam nyob rau hauv qhov kub thiab txias
- Tag nrho cov xov sib koom nro; sealing kev cia siab deb dua rau siab -siab flanges
4, Daim Ntawv Thov Scenarios
Ob Chav End Stud Haum Scenarios (PN Tsawg dua lossis sib npaug rau 40, Tsawg / Nruab Nrab Siab)
- Cov cuab yeej siv tshuab dav dav, qis- cov kav dej / cua tshuab
- Lub tsev steel qauv, cov khoom siv zoo tib yam plhaub, lub tog raj kheej lub taub hau
- Feem ntau disassembled qis- cov cuab yeej muaj kev pheej hmoo, tsis yog- tshuaj lom & tsis- nruab nrab flammable
- Tsau- thickness txuas qhov twg tuav ntev tsis hloov
Tag Nrho Threaded Stud Yam Yuav Tsum Tau Ua (PN ＞ 40, Kev Ua Haujlwm hnyav)
- Petrochemical, roj & roj, LNG, siab -siab valve flanges
- Cov hlab ntsha siab, cov khoom siv hluav taws xob hloov pauv, siab - cov khoom siv hluav taws xob kub
- Marine offshore cua zog, ntsev pos corrosion hnyav kev lag luam
- Toxic, flammable, explosive nruab nrab pipeline (txhim tiv thaiv- yuav tsum tau leak)
- Variable -thickness flanges, multi- txheej txheej gaskets, adjustable clamping nrug
5, Yuav ua li cas xaiv cov khoom?
1. Kev ua haujlwm siab tsawg dua lossis sib npaug ntawm PN40, huv si tsis yog - qhov nruab nrab muaj kev phom sij, ruaj khov kev sib txuas thickness → Xaiv Ob Qhov Kawg Stud kom txuag tau nqi
2. Ua hauj lwm siab ＞ PN40, kub siab, kev co, tshuaj lom/flammable nruab nrab, txawv txawv flange thickness → Yuav tsum siv tag nrho Threaded Stud
3. Offshore, ntug hiav txwv ntsev pos huab, tshuaj corrosion ib puag ncig: Tag nrho threaded stainless hlau stud (A193 B8M 316) nrog Ruspert txheej
4. High-kub rauv, cov khoom siv thermal: A193 B7 tag nrho threaded stud nrog 2H hnyav txiv ntoo
Handan Jihao Fasteners Co., Ltd. tshwj xeeb hauv kev tsim ntau yam ntawm tag nrho cov threaded studs thiab ob - xaus studs. Peb kuj lees txais kev txiav txim rau cov uas tsis yog- tus qauv fasteners thiab ntsia liaj qhov rooj thiab cov txiv ntoo.
