Chitoliro chachitsulo cha ASTM A53 B ERWKugwiritsa ntchito
1 Zomangamanga: mapaipi apamwamba kwambiri pansi pamadzi ochulukirapo apansi panthaka ngati nsanja, ma boilers, kutengera madzi otentha ndi zina zotero.
2 Machining, kubala akanema, makina processing ndi zipangizo zina.
3 Gulu lamagetsi: kugawa gasi, njira yamadzimadzi yamadzimadzi.
4 Anti-static machubu magetsi opangira mphepo.
Chitoliro cha Chitsulo cha ASTM A53 B ERW chimakwirira mitundu iyi ndi magiredi:
Type E—Electric-resistance-welded, Magiredi A ndi B
