Chitoliro Chachitsulo cha ASTM A53

ASTM A53 Structural Steel Pipe Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Chitoliro cha ASTM A53 (chomwe chimadziwikanso kuti ASME SA53 chitoliro) chimagwiritsidwa ntchito pamakina ndi kukakamiza ndipo chitha kugwiritsidwanso ntchito ngati mapaipi amadzi, madzi, gasi ndi mpweya.

Machubu Azitsulo Opanda Msoko Pazolinga Zamapangidwe, Machubu Achitsulo Opanda Msoko Pamakina Amakina Mu GB/8162-2008 Standard.Zofunika Zimaphatikizapo Chitsulo Chapamwamba cha Carbon Ndi Chitsulo Chotsika, Monga 10,20,35,45 Ndi Q345,Q460,Q490,42CrMo,35CrMo.

Kugwiritsa ntchito: Makina ndi kuthamanga, komanso potengera nthunzi, madzi, gasi, ndi zina.

Kugwiritsa ntchito

Kugwiritsa ntchito makina ndi kuthamanga, komanso kunyamula nthunzi, madzi, gasi ndi zina.

Zikalata zoyeserera za Mill zidzaperekedwa malinga ndi EN10204/3.1B.

Chitoliro cha ASTM A53 (chomwe chimatchedwanso ASME SA53 chitoliro) chimapangidwa kuti chizigwiritsidwa ntchito pamakina ndi kukakamiza ndipo ndichovomerezeka kuti chigwiritsidwe ntchito wamba munjira za nthunzi, madzi, gasi, ndi mpweya.Ndi yoyenera kuwotcherera, ndipo ndi yoyenera kupanga maopareshoni ophatikiza kupindika, kupindika, ndi kuwotcherera, malinga ndi ziyeneretso zina.

Zida ndi Kupanga

Chitsulo cha chitoliro chopanda msoko ndi chowotcherera chidzapangidwa ndi chimodzi kapena zingapo mwa njira zotsatirazi: malo otseguka, ng'anjo yamagetsi, kapena Basic-oxygen.Msoko wowotcherera wa chitoliro chamagetsi chosasunthika mu Gulu B uyenera kutenthedwa pambuyo powotcherera.

Mapulogalamu: osinthanitsa kutentha, ma condensers, zida zotumizira kutentha ndi mapaipi ofanana.

Chitoliro chachitsulo cha A53 Grade B Seamless steel chitoliro chathu ndichopanga polar kwambiri pansi pa izi ndipo chitoliro cha A53 nthawi zambiri chimakhala chovomerezeka cha A106 B Chitoliro chosasunthika.

Chitoliro cha A53 chimabwera m'mitundu itatu (F, E, S) ndi magiredi awiri (A, B).

Mtundu wa A53 E uli ndi weld kukana magetsi (Makalasi A ndi B).

A53 Type S ndi chitoliro chopanda msoko ndipo chimapezeka m'magiredi A ndi B).

Mtundu wa A53 F umapangidwa ndi chowotcherera ng'anjo yamoto kapena ukhoza kukhala ndi weld mosalekeza (Giredi A yokha).

Kulongedza
