Wopanga Mapaipi Achitsulo Otsogola & Wopereka Ku China |

Tsatanetsatane wa Chitoliro chachitsulo cha ASTM A671 EFW

Chithunzi cha ASTM A671 ndi chitoliro chachitsulo chopangidwa kuchokera ku mbale yamtengo wapatali,Electric-Fusion-Welded (EFW)kwa malo omwe ali ndi mphamvu zambiri pamalo ozungulira komanso otsika.

Ndikoyenera makamaka kwa ntchito zomwe zimafuna kukhazikika kwapamwamba komanso kutsika kwapadera.

Chitoliro chachitsulo cha ASTM A671 EFW

Kukula kwa ASTM A671

Mitundu yovomerezeka: mapaipi achitsulo ndi DN ≥ 400 mm [16 mu] ndi WT ≥ 6 mm [1/4].

Itha kugwiritsidwanso ntchito pamiyeso ina ya chitoliro, malinga ngati ikukwaniritsa zofunikira zina zamtunduwu.

Chizindikiro cha ASTM A671

Kuti timvetse bwino ASTM A671, choyamba timvetsetse zomwe zili zolembera.Izi zimathandiza kumveketsa kukula kwa kagwiritsidwe ntchito ndi mawonekedwe a muyezo uwu.

Chitsanzo cha Spray Marking:

BOTOP EFW ASTM A671 CC60 -22 16"×SCH80 HEAT NO.4589716

BOMA: Dzina la wopanga.

EFW: Njira yopangira chubu chachitsulo.

Chithunzi cha ASTM A671: Executive Standard for Steel Tubing.

Mtengo wa CC60-22: Chidule cha giredi:cc60 ndi kalasi 22.

16 "x SCH80: Diameter ndi Makulidwe a Khoma.

KUCHERA NO.4589716: Kutentha ayi.popanga machubu achitsulo.
