Kulongedza kwa JIS 3454 Carbon ERW Steel Pipe

Chitoliro chopanda kanthu, zokutira zakuda kapena kuviika kotentha kwa zinki (zosinthidwa);
M'mitolo yokhala ndi gulaye ziwiri za thonje;
Zonsezi zimathera ndi otetezera mapeto;
Mapeto ang'onoang'ono, mathero a bevel (Pakafunika ndi wogula ndi S≤22mm, mapeto a chitoliro ayenera kugwedezeka, digiri: 30 ° (+5 ° ~ 0 °), ndipo makulidwe a khoma la muzu sakuchepetsedwa ndi <2.4 mm.);
Kuyika chizindikiro.
