I-SAKY STEEL ihlinzeka nge-304 Stainless Steel Rectangular Tube, ukumiswa kwayo komumo webhokisi kuyenza iqine, iqine futhi iqine. Lawa mashubhu ensimbi angunxande kulula ukuwashisela, ukusika, ukwakha kanye nomshini onempahla nolwazi olufanele. Sinikezela ngohlu olubanzi lwamashubhu angamaRectangular Stainless Steel 304 kumakhasimende ethu emimbonini eyahlukene. Amashubhu angamaRectangular we-SS angenamthungo asetshenziswa kabanzi kuzo zonke izinhlobo zezinhlelo zokusebenza zesakhiwo namaphrojekthi wokwenza lapho kudingeka khona amandla amakhulu nokumelana nokugqwala okuphakeme. Ngokusho kwezinhlelo zokusebenza ezihlukene, amashubhu angama-304 Stainless Steel Rectangular anobubanzi obuhlukene. Noma yikuphi ukwenza ngokwezifiso kuyadingeka, lawa mashubhu angamaRectangular angenziwa ngezifiso kalula. I-SAKY STEEL Industries ikhethekile ngokuhlinzeka nge-SS Rectangular Tube ekuqedeni kwe-Polished Grit 120 – 600.
Kwa-SAKY STEEL Industries singenza ngokwezifiso i-304 Rectangular Steel Tube efanelekile yohlelo lwakho lokusebenza oluyingqayizivele. Xhumana ne-SAKY STEEL Industries ukuze uqinisekise ukutholakala namanani entengo.
Njengesitoko esikhulu kunazo zonke se-Stainless Steel Rectangular Tube, sinohlu olukhulu lwe-Stainless Steel 304 Rectangular Tube, Stainless Steel 304L Rectangular Tube, Stainless Steel 304 Rectangular Tube, SS 316 Rectangular Tube, kanye ne-Stainless Steel Rectangular Tube 201.
| SS AMASHUBHA ALUNGANGOBULUNGA: |
Amashubhu angama-SS Rectangular aqedwa ngokuvumelana nezidingo zekhasimende mayelana nokucaciswa kobukhulu nokuqina kodonga kanye nokwelashwa kokushisa kwezinhlelo zokusebenza ezifuna kakhulu. Ngokuvamile i-Stainless Steel Rectangular Tube ikhiqizwa ngokuvumelana nezindinganiso zamanje ze-API, i-ASTM, ne-ASME. Uma kudingeka kumaphrojekthi akhethekile singahlinzeka ngamashubhu amakhulu angama-Rectangular.
