High-Simba Bolts: Kupi uye Rini Kuashandisa

2026-05-25

Chii Chinoita Bolt Yakakwirira-Simba?

High-simba mabhaudhi anotsanangurwa nematatu epakati paramita:

Kusimba kwesimba - iyo yakanyanya mutoro bhoti inogona kumira isati yatsemuka (yakayerwa muMPa)
Goho simba - mutoro apo bhaudhi inotanga kukanganisa zvachose
Proof load - pre-tension inoshandiswa panguva yekuisa kugadzira clamping simba mujoini

High-simba mabhaudhi anowanzo kugadzirwa kubva epakati-kabhoni simbi kana alloy simbi uye kurapwa kupisa (kudzima uye kupisa) kuti uwane inodiwa michina zvinhu. Majasi epamusoro - senge zinc plating, Dacromet, kana Luxubao - anoiswa kuti akwidziridze kushomeka pasina kukanganisa simba.

CHOKWADI CHIKURU Mabhaudhi eGrade 10.9 ane simba rekusimba re1,000 MPa - inodarika 3× yakasimba kudarika bhaudhi yehardware yeGrade 4.6.

Makiyi Ekushandisa Sector

High-simba mabhaudhi anoshandiswa kumativi ese anorema-industry sector. Tafura iri pazasi inoratidzira nzvimbo dzinowanzo kunyorera uye dzinoenderana mhando dzekusimbisa:

Structural Simbi & Kuvaka

Indasitiri yekuvaka ndiyo mutengi mukuru wepamusoro-simba mabhoti. Structural bolt yekubatanidza inotsiva yechinyakare welding mumajoini-kune-column, ichipa kukurumidza kuisirwa, kuongorora kuri nyore, uye kuramba kwakanyanya kune seismic mitoro.

Hex mabhaudhi (Giredhi 8.8 / 10.9) - anoshandiswa mukubatana-kuramba kubatanidza, base plate anchors, uye splice mahwendefa
Anchor bolts - akaiswa mukongiri nheyo kuti achengetedze zvimiro zvesimbi makoramu
Heavy hex mabhaudhi ane nzungu - chiyero cheAISC uye EN 1090-inoenderana nesimbi furemu yekubatanidza

PRO ZANO Kune anotsvedza-akakosha ekubatanidza, gara uchishandisa ASTM A325 kana A490 mabhaudhi ane akaomeswa washer uye calibrated torque wrenches.

Bridges & Civil Infrastructure

Kuvakwa kwebhiriji kunoda mafasteners anogona kutsungirira mitoro inorarama, kuwedzera kwemafuta, uye makumi emakore ekuratidzwa kwezvakatipoteredza. Mabhaudhi emasimba epamusoro-soro anotsanangurwa mumakodhi ebhiriji epasi rose anosanganisira AASHTO, Eurocode 3, uye GB/T zviyero.

Mabhaudhi eFlange - batanidza zvikamu zvegirder zvesimbi pamazambuko
Stud mabhaudhi ane nzungu - chengetedza majoini ekuwedzera uye mabearing plate assemblies
Dacromet-yakavharwa hex mabhaudhi - yakarongedzerwa kumahombekombe uye kumahombekombe ebhiriji zvivakwa kudzivirira ngura.

Mhepo Energy & Power Generation

Wind turbine towers dzakaunganidzwa dzichishandisa mahombe-diameter akasimba-akasimba mabhaudhi e-flange - kazhinji Giredhi 10.9 kana 12.9 - akatarisana nemitoro yekuneta mukati mehupenyu hwavo hwesevhisi hwemakore makumi maviri nemashanu. Bolt preload kurongeka kwakakosha; mabhaudhi akadzivirirwa anokonzera kupera simba kweshongwe, ukuwo mabhaudhi akaomeswa achiburitsa njodzi.

Shongwe flange mabhaudhi (M36–M72, Giredhi 10.9) - inonyanya kudiwa yakakwirira-simba rebhoti application mune inovandudzwa simba chikamu
Foundation anchor bolts - batanidza hwaro hweshongwe kune hwaro hwekongiri
Nacelle uye rotor hub mabhoti - yemukati dhizaini yekubatanidza ine yakasimba torque zvinodiwa

COATING NOTE Zinc-flake / Luxubao-yakavharwa mabhaudhi anofarirwa shongwe yemhepo application - inopa yakanyanya kuomarara kuramba uye haina hydrogen-embrittlement-isina.

Heavy Machinery & Industrial Equipment

Madhishi, macrusher, midziyo yemugodhi, uye magiya magiya maindasitiri anoburitsa mitoro inosimba yakanyanyisa inoda kusungirirwa kwesimba repamusoro. Kusunungura bhoti mumakina anotenderera kunogona kukonzera kutadza kukuru uye kuderera kwekugadzira.

Socket head cap screws (Giredhi 12.9) - inoshandiswa munzvimbo dzakavharirwa uko kusingawanikwe kwakajairwa hex.
Flange mabhaudhi - inopa kuzvimiririra uye kuramba lateral shear mauto mumakina ekumisikidza
Seta screws uye grub screws - chengetedza zvinhu zvinotenderera kune shaft pasina misoro inoburitsa

Mafuta, Gasi uye Petrochemical

Pipeline flange yekubatanidza uye yekumanikidza ngarava inovhara muoiri uye gasi indasitiri inoshanda pasi pekumanikidzwa kwakanyanya, tembiricha yakanyanyisa, uye inoparadza midhiya. Mafasteners munzvimbo idzi anofanirwa kusangana neASME B16.5 uye ASTM A193/A194 zviyero.

ASTM A193 B7 stud bolts (Cr-Mo alloy simbi) - iyo indasitiri chiyero chepamusoro-tembiricha yekubatanidza flange
2H inorema hex nzungu (ASTM A194) - yakapetwa neB7 studs yedzvinyiriro-yakatemerwa flanges
Incoloy / super-alloy bolts - yakatsanangurwa kune yakanyanya corroy kana cryogenic sevhisi mamiriro

Kudzivirirwa kweCorrosion kune High-Simba Bolts

Corrosion ndiyo inotungamira kukonzeresa kutadza kwekukurumidza kumhanyisa munzvimbo dzekunze uye dzemaindasitiri. Kusarudza kurapa kwakakodzera kwepamusoro kwakakosha - kunyanya kune mabhaudhi ane simba repamusoro apo hydrogen embrittlement kubva ku electroplating injodzi chaiyo pamusoro peGrade 10.9.

Dacromet coating - mvura-based, chromate-isina, 480-1000+ h munyu-spray resistance; yakachengeteka yeGrade 10.9/12.9 mabhaudhi
Luxubao (zinc-flake) coating - yakafanana neGeomet/Delta-Tone; yakanakira simba remhepo uye kuvaka kunorema
Hot-dip galvanizing - yakakodzera Giredhi 8.8 uye pasi; isingakurudzirwe pamusoro peGrade 10.9 nekuda kwengozi yehydrogen
Zinc electroplating - yehupfumi sarudzo yemukati kana yakaderera-kuratidzwa nharaunda
Stainless simbi (A2-70 / A4-80) - muzvarirwo ngura-resistant; hapana kumwe kupfekedzwa kunodiwa

Sei Kusarudza FUJINRUI Yakakwirira-Simba Fasteners?

Yakagadzirwa ku ISO 898-1, ASTM A325/A490, uye DIN 931/933 zviyero.
Yakazara mhando yejasi: Dacromet, Ruspert, zinc-plated, inopisa-dip galvanized, phosphate.
Saizi kubva M6 kusvika M64, simba mamakisi 8.8 / 10.9 / 12.9
Wechitatu-bato mekiniki yekuyedza zvitupa zviripo (tensile, kuoma, munyu-spray)
Mitengo yemakwikwi inokurumidza kutungamira nguva yeOEM yakawanda uye maodha eprojekiti
