Kvadratna cev je dolga jeklena palica z votlo notranjostjo. Ime je dobila po kvadratnem prerezu. Ker je izdelana iz jekla, je zelo trpežna. Prav tako je odporna proti koroziji, rji in madežem. Te cevi lahko prenesejo celo kisline, slano vodo in kemikalije.

Ta vrsta cevi je razdeljena v dve kategoriji – brezšivne jeklene cevi in varjene jeklene cevi. Kot že ime pove, ima brezšivna jeklena cev gladko in neovirano sestavo ter nima varov na površini. Varjena jeklena cev pa ima upognjeno jekleno ploščo, ki je varjena v kvadratno obliko, kar ustvari šiv na telesu cevi.

Velikost: 10*10～500*500 mm
Debelina stene: 0,6～30 mm
Površina: oljeno/barvano/pocinkano
Dolžina: 3～12 m

podrobnosti o izdelku

SMSTEKELKvadratna/pravokotna cev

● Predhodno pocinkana kvadratna/pravokotna cev: Predhodno pocinkana kvadratna/pravokotna cev je izdelana neposredno iz vroče pocinkanega jeklenega traku.

● Vroče pocinkana kvadratna/pravokotna cev: Vroče pocinkana kvadratna/pravokotna cev ima debelejšo cinkovo prevleko kot predhodno pocinkana kvadratna/pravokotna cev. Črne cevi se za cinkanje potopijo v cinkovo kopel.

● Elektro pocinkana kvadratna/pravokotna cev: Tehnologija elektro pocinkane kvadratne/pravokotne cevi je podobna vroče pocinkani cevi, vendar je debelina cinkove prevleke manjša kot pri vroče pocinkani cevi.

● Pobarvano kvadratno/pravokotno: Pobarvano kvadratno/pravokotno, da se najprej odstrani rja in očisti olje, nato pa se nanese želena barvna barva.

SMSTEKELPogoste uporabe kvadratne cevi

Odpornost kvadratnih cevi jim omogoča široko področje uporabe na prostem. Zaradi votle notranjosti so odlične tudi za transport tekočin, kot so bencin, voda in drugi naftni derivati.

Kljub robustni strukturi so te cevi relativno lahke in jih je mogoče upogniti, da se prilagodijo različnim primerom uporabe. So tudi bistveni sestavni deli pri proizvodnji določene opreme, mehanskih delov in industrijske infrastrukture.
