1. Cov ntsiab lus tseem ceeb: EN 10305-1 yog dab tsi?
TS EN 10305-1 yog ib feem ntawm cov qauv ntawm cov qauv (EN 10305) rau "Steel hlab rau cov ntawv thov kom raug." Part 1 tshwj xeeb npog:
Txheej txheem:Seamless thiab txias - kos.
Khoom siv:Tsis yog{0}} alloy (carbon) steel.
Cov yam ntxwv tseem ceeb:Tighter dimensional tolerances, zoo dua nto tiav, thiab ntau yam khoom siv tshwj xeeb piv rau cov qauv txheej txheem los yog siab tubing.
Qhov "precision" hauv lub npe yog qhov tseem ceeb sib txawv. Cov raj no yog tsim los rau kev tswj hwm nruj dua kom ntseeg tau tias muaj kev sib luag thiab kev ntseeg siab hauv cov ntawv thov tseem ceeb.
2. Cov yam ntxwv tseem ceeb thiab cov yam ntxwv
High Dimensional Accuracy:Tolerances ntawm sab nraud txoj kab uas hla (OD) thiab phab ntsa tuab yog nruj dua rau cov qauv raj (xws li EN 10255 los yog ASTM A513). Qhov no yog qhov tseem ceeb rau cov ntawv thov uas muaj lub tog raj kheej pneumatic, lub tog raj kheej hydraulic, thiab cov kabmob vaj tse.
Zoo heev Surface Finish:Cov raj muaj qhov du, huv si sab hauv thiab sab nraud, feem ntau yuav tsum tsis muaj kev siv tshuab ntxiv.
Superior Mechanical Properties:Qhov txias- txheej txheem kos duab ua haujlwm- hardens cov hlau, ua rau muaj zog tensile ntau dua thiab muaj zog tawm los piv rau cov kub kub- tiav lawm.
Kev kuaj tshwj xeeb:Txoj cai tswjfwm nruj nruj tsis yog-kev kuaj kev puas tsuaj (NDT), feem ntaueddy kev kuaj tam sim no, kom ntseeg tau tias muaj kev ncaj ncees thiab txheeb xyuas qhov tsis zoo. Kev ntsuam xyuas hydrostatic kuj tuaj yeem teev tseg.
3. Cov Qib Qib Hlau
EN 10305-1 qhia txog ntau qib steel, feem ntau raws li lawv qhov tsawg kawg nkaus yield zog (Re). Cov feem ntau yog:
E235:Ib qho dav - qib hom phiaj nrog qhov tsawg kawg nkaus tawm lub zog ntawm 235 MPa.
E355:Qib siab - muaj zog nrog qhov tsawg kawg nkaus tawm lub zog ntawm 355 MPa. Qhov no yog ib qho ntawm cov qib siv dav tshaj plaws.
Lub npe feem ntau suav nrog kev xa khoom, piv txwv li:
E355 +C(Kev ua haujlwm txias, kuaj rau 6.3 MPa)
E355 +N(Normalized, rau kev txhim kho machinability thiab ntau yam khoom sib xws)
4. Cov ntawv thov ib txwm
Vim lawv qhov tseeb thiab qhov zoo, cov raj no tau siv rau hauv cov ntawv thov uas muaj kev ntseeg siab thiab qhov ntev yog qhov tseem ceeb:
Hydraulic thiab Pneumatic Lub tog raj kheej:Qhov tseem ceeb siv. Lub raj ua raws li lub tog raj kheej kheej kheej.
Linear Motion Systems:Rau kev taw qhia lub tes tsho, actuator vaj tse, thiab shock absorber cylinders.
Automotive Kev Lag Luam:Shock absorber struts, roj txhaj tshuab, thiab lwm yam precision Cheebtsam.
Bearing Races and Housings:Qhov twg lub raj nws tus kheej yog siv los ua cov haiv neeg sab hauv lossis sab nrauv rau cov kabmob.
General Mechanical Engineering:Rau shafts, pins, thiab lwm yam khoom uas muaj siab -zoo, npaj tau- rau- siv raj yog xav tau.
5. Sib piv nrog lwm cov qauv
Nws yog qhov pab tau kom nkag siab tias EN 10305-1 piv rau lwm cov qauv raj li cas.
| Feature | TS EN 10305-1 | TS EN 10255 Kev Lag Luam Tubes | ASTM A513 (Tebchaws Mechanical Tubing) | ASTM A106 (Npaj yeeb nkab) |
|---|---|---|---|---|
| Kev siv thawj zaug | Precision Engineering | Lub hom phiaj dav dav, kav dej | Kev siv tshuab | Siab -Temp/Pressure Service |
| Dimensional Tolerances | Tight heev | Standard / Loose | Zoo / txawv ntawm hom | Txuj rau cov yeeb nkab |
| Nto tiav | Zoo heev | Txuj | Zoo | Txuj |
| Txheej txheem | Cold Drawn Seamless | Welded & Cold Drawn | Electric Resistance Welded (ERW) los yog DOM | Seamless los yog Welded |
| Ntsiab Standard | Dimensional Precision | Nqi & Muaj | Lub zog & Weldability | Siab Containment |
Nco tseg ntawm "DOM" (Drawn Over Mandrel):Thaum EN 10305-1 raj yog seamless thiab txias-draw, American sib npaug ntawm daim ntawv thov thiab zoo feem ntau suav hais tias yogDOM (Drawn Over Mandrel) tubingrauASTM A513 Hom 5. Txawm li cas los xij, EN 10305-1 feem ntau qhia txog kev ua siab ntev dua.
6. Cov ntaub ntawv xaj xaj
Thaum txiav txim EN 10305-1 tubing, koj yuav tsum qhia meej:
Txheem:TS EN 10305-1
Qhov Loj:Sab nraud Diameter (OD) thiab Phab Ntsa Thickness (WT) hauv mm.
Steel Qib: e.g., E235, E355.
Delivery condition:Piv txwv li, +C (Cold worked), +N (Normalized).
Ntev:Ntev ntev los yog random.
Hom Kev Xeem:Piv txwv li, Eddy kev sim tam sim no (tus qauv), Hydrostatic test (yog tias xav tau).
Cov ntsiab lus
TS EN 10305-1txhais lub siab -zoo,txias- kos seamless carbon steel rajmanufactured rauprecision kam rau uathiab nrog zoo heev nto tiav thiab mechanical zog. Nws yog qhov mus- mus rau cov khoom siv rau European engineering designs xav tau kev txhim khu kev qha, npaj tau-- siv tubing rau hydraulic thooj voos kheej kheej, linear actuators, thiab lwm yam siab - precision mechanical applications.
Yog tias koj tab tom ua haujlwm ntawm tus qauv tsim uas hu rau tus qauv zoo li DIN 2391 (uas nws feem ntau hloov pauv), EN 10305-1 yog qhov sib npaug European niaj hnub koj yuav tsum tau qhia meej.
