MITUNDU NDI KAGWIRITSIDWA NTCHITO ZINTHU ZOCHITIKA PA PIPI INDUSTRY
Pamene njira zopangira zasintha ndikukhala zovuta kwambiri, kusankha kwa ogula zitsulo kwawonjezeka kuti akwaniritse zofunikira zambiri m'mafakitale osiyanasiyana.

Koma sizitsulo zonse zomwe zimakhala zofanana. Pofufuza mitundu yachitsulo yomwe ilipo kuchokera kwa ogulitsa chitoliro cha mafakitale ndikumvetsetsa chifukwa chake zitsulo zina zimapanga chitoliro chabwino kwambiri ndipo ena satero, akatswiri amakampani opanga mapaipi amakhala ogula bwino.

CARBON zitsulo
Chitsulochi chimapangidwa powonjezera chitsulo chofooka ku carbon. Mpweya ndiye chinthu chodziwika kwambiri chowonjezera pazitsulo zachitsulo m'makampani amakono, koma ma alloying amitundu yonse amagwiritsidwa ntchito kwambiri.

Pakumanga mapaipi, chitsulo cha kaboni chimakhalabe chitsulo chodziwika kwambiri. Chifukwa cha mphamvu zake ndi chosavuta processing, mpweya zitsulo chitoliro chimagwiritsidwa ntchito m'madera ambiri. Chifukwa lili ndi zinthu zochepa alloying, mpweya zitsulo chitoliro ndi otsika mtengo pa ndende otsika.

Mpweya wa carbon zitsulo structural mapaipi ntchito zamadzimadzi zoyendera, mafuta ndi gasi zoyendera, zida, magalimoto, magalimoto, etc. Pansi katundu, mpweya zitsulo mapaipi sapinda kapena kusweka ndipo bwino welded mu kalasi A500, A53, A106, A252.

zitsulo zitsulo
Chitsulo cha aloyi chopangidwa ndi kuchuluka kwachulukidwe kwa zinthu za alloying. Nthawi zambiri, zigawo za alloy zimapangitsa chitsulo kukhala cholimba kupsinjika kapena kukhudzidwa. Ngakhale faifi tambala, molybdenum, chromium, silicon, manganese ndi mkuwa ndi zinthu zofala alloying, zinthu zina zambiri amagwiritsidwanso ntchito popanga zitsulo. Amagwiritsidwa ntchito popanga, pali mitundu ingapo ya ma alloys ndi zoyikapo, ndi kuphatikiza kulikonse komwe kumapangidwira kukwaniritsa mikhalidwe yosiyana.
Chitoliro cha Chitsulo cha Aloyi chikupezeka kukula kwake pafupifupi 1/8′ mpaka 20′ ndipo chili ndi ndandanda monga S/20 mpaka S/XXS. M'malo oyeretsera mafuta, zomera za petrochemical, zomera za mankhwala, mafakitale a shuga, ndi zina zotero, mapaipi azitsulo amagwiritsidwanso ntchito. Mipope yachitsulo ya alloy imakonzedwa bwino, yopangidwa ndikuperekedwa pamtengo wokwanira malinga ndi zomwe mukufuna.

CHITSULO CHOSAPANGA DZIMBIRI
Mawu awa ndi onyansa pang'ono. Palibe kusakanikirana kwapadera kwazitsulo ndi aloyi zomwe zimapanga zitsulo zosapanga dzimbiri. M’malo mwake, zinthu zopangidwa ndi zitsulo zosapanga dzimbiri sizichita dzimbiri.
Chromium, silicon, manganese, faifi tambala ndi molybdenum angagwiritsidwe ntchito mu kasakaniza wazitsulo zosapanga dzimbiri. Kuti alankhule ndi okosijeni mumpweya ndi m’madzi, ma aloyiwa amagwirira ntchito limodzi kuti apangire mwachangu filimu yopyapyala koma yolimba pazitsulozo kuti zisawonongeke zina.

Chitoliro chachitsulo chosapanga dzimbiri ndiye chisankho choyenera m'magawo omwe kukana kwa dzimbiri ndikofunikira komanso kulimba kwambiri kumafunika monga magetsi a sitima yapamadzi, mitengo yamagetsi, kuthira madzi, mankhwala ndi mafuta ndi gasi. Ikupezeka mu 304/304L ndi 316/316L. Yoyamba imakhala yosagwira dzimbiri komanso yolimba, pomwe mtundu wa 314 L umakhala ndi mpweya wochepa kwambiri ndipo ndi wowotcherera.
