Yuav Ua Li Cas Paub Txog Qib 1 titanium Tube cuav
May 22, 2026
Txoj Kev 1: Kos Xim
| Khoom siv | Xim | Txiav txim |
|---|---|---|
| Tiag tiag Gr.1 Titanium | Grey-dawb, me ntsis npub, tsis ci | ✅ Muaj tiag |
| Stainless hlau | Bright silver, heev reflective | ❌ Fake (stainless hlau) |
| Aluminium | Cov nyiaj ci heev, ntau sib dua hauv qhov hnyav | ❌ Fake (Aluminium) |
Lub raj titanium tiag feem ntau yog pickled los yog annealed, ua rau ib qho grey sib xws -dawb tiav. Yog hais tias lub raj yog ci heev, nws yuav zoo li stainless hlau.
Txoj Kev 2: Ntsuas Nws
Titanium density yog4.51 g / cm³. Stainless hlau yog7.9 g / cm³. Aluminium yog2.7 g / cm³.
Yuav kuaj li cas:
Txiav ib qho me me ntawm lub raj (los yog siv tag nrho ntev yog tias ua tau)
Ntsuas nws precisely
Xam qhov ceev=nyhav / ntim
| Khoom siv | Qhov ceev (g / cm³) | Qhov hnyav piv rau titanium |
|---|---|---|
| Gr.1 Titanium | 4.51 | Lub hauv paus |
| Stainless hlau | 7.9 | 75% hnyav dua |
| Aluminium | 2.7 | 40% sib dua |
Nqa ib lub raj stainless hlau thiab lub raj titanium ntawm tib qhov loj. Titanium yog qhov sib dua - txog ib nrab ntawm qhov hnyav ntawm stainless hlau.
Txoj Kev 3: Spark Test (Kev Sib Tsoo Sib Tsoo)
Thaum sib tsoo titanium vs stainless hlau los yog txhuas, lub txim txawv txawv.
| Khoom siv | Spark Pattern | Txiav txim |
|---|---|---|
| Gr.1 Titanium | Bright dawb sparks, tsawg heev, luv luv | ✅ Muaj tiag |
| Stainless hlau | Txiv kab ntxwv - liab sparks, ntau, ntev tail | ❌ Fake |
| Aluminium | Tsis muaj sparks - tsuas yog smears | ❌ Fake |
Yuav ua li cas:Siv lub grinder rau ntawm lub raj nplaim. titanium tsim cov ci ntsa iab dawb. Stainless hlau ua txiv kab ntxwv - liab sparks. Aluminium ua tsis muaj sparks.

Ntim
TxhuaGr.1 titanium rajyog ib tus zuj zus qhwv rau hauv zaj duab xis yas los yog VCI daim ntawv kom tsis txhob ya raws thiab khawb. Ob qhov kawg yog kaw nrog lub kaus mom yas kom tsis txhob muaj khib nyiab. Cov raj yog bundled nrog steel straps thiab tiv thaiv padding, ces packed nyob rau hauv export - txheem plywood ntoo thawv rau seaworthy xa. Cov ntawv sau nrog qib, tus naj npawb cua sov, qhov loj me, thiab qhov ntau yog txuas rau txhua lub nras thiab lub thawv. Kev ntim ntim yog muaj raws li qhov kev thov.
Khoom siv Hoobkas
GNEE ua haujlwm txias pilger mills rau seamless raj ntau lawm, TIG welding kab rau welded raj, nqus annealing furnaces rau kev kho cua sov, thiab straightening cov cav tov rau seem raug. Rau kev tswj kom zoo, peb muaj eddy tam sim no testers, ultrasonic testers, thiab hydrostatic kuaj khoom. U- cov tshuab dabtsi yog khoov muaj rau kev sib hloov lub raj kub.
