1. Kev xaiv khoom & Metallurgical tsom
Q:Cov khoom specifications txawv ntawm cov yeeb nkab no li cas?
A:
Idler Pipes:
Qib:ASTM A53 B (σᵧ Ntau dua lossis sib npaug rau 240 MPa), St52 (DIN 2391).
Qhov tseem ceeb:Hnav tsis kam (150–200 HB hardness), weldability (Ceq Tsawg dua lossis sib npaug rau 0.43).
Precision Tubes:
Qib:EN 10305-1 E355, ASTM A 519 1026.
Qhov tseem ceeb:Homogeneous microstructure (tag nrho normalized), tswj nruj ntawm kev koom ua ke (tsawg dua lossis sib npaug rau 1.5 qhov ntsuas ntawm ISO 4967).
Qhov txawv tseem ceeb:Precision tubes undergotheem nrab refining(piv txwv li, lub tshuab nqus tsev degassing) rau purity.
2. Dimensional Tolerances & Geometric Precision
Q:Dab tsi yog qhov sib txawv ntawm qhov tseem ceeb?
A:
| Parameter | Idler Pipes | Precision Tubes |
|---|---|---|
| OD Tolerance | ± 0.3 hli (ISO 13934) | ± 0.05 hli (ISO 3304) |
| Phab ntsa Variation | Tsawg dua lossis sib npaug li 8% | Tsawg dua lossis sib npaug li 3% (tsawg dua lossis sib npaug li 1% rau cov raj honed) |
| Kev ncaj | 0.5 hli / m | 0.1 hli / m (laser-tuaj xyuas) |
| Nco tseg:Precision raj feem ntau xav tausib tsoo / honing(Ra Tsawg dua lossis sib npaug li 0.8 µm) rau mating qhov chaw. |
3. Kev tsim cov txheej txheem sib piv
Q:Txoj kev tsim khoom sib txawv li cas?
A:
Idler Pipes:
Txheej txheem:HFW/ERW vuam los yog kub- dov seamless.
Tom qab-kev kho mob:Basic sizing, qee zaus galvanizing.
Precision Tubes:
Txheej txheem:Txias-kos seamless (CDS) nrog ntau-theem annealing.
Tom qab-kev kho mob:Kev ntxhov siab -relieving, ultrasonic tu, passivation.
Tus nqi Factor:Precision tube ntau lawm yog2.5-4x kim duavim cov kauj ruam ntxiv.
4. Nto Finish & Functional Coatings
Q:Cov kev cai saum npoo sib txawv li cas los ntawm kev thov?
A:
Idler Pipes:
Sab nraud:Kub-dip galvanized (80 µm) lossis epoxy-coated.
Sab hauv:Polished (Ra Tsawg dua lossis sib npaug li 1.6 µm) kom txo tau kev sib txhuam.
Precision Tubes:
Sab nraud:Hard chrome plated (20–30 µm) lossis npib tsib xee -PTFE coated.
Sab hauv:Daim iav-ua tiav (Ra Tsawg dua lossis sib npaug li 0.4 µm) rau cov kua dej / pneumatic.
2025 Trend:Pob zeb diamond-zoo li cov pa roj carbon (DLC) txheej rau precision raj hauv cov khoom siv semiconductor.
5. Kev Tswj Xyuas Zoo & Ntawv Pov Thawj
Q:Cov qauv siv tau li cas rau txhua tus?
A:
Idler Pipes:
Kev xeem:UT + hydrostatic (raws li ASTM A530).
Daim ntawv pov thawj:ISO 9001 + CMS 70: 2022 (Conveyor Mfg Standard).
Precision Tubes:
Kev xeem:Eddy tam sim no, spectroanalysis, roundness mapping.
Daim ntawv pov thawj:ISO 10763 (hydraulic), AD2000-W0 (cov hlab ntsha siab).
