"Chitsulo Chopangira Chitoliro cha Chitoliro HTASTM A335 GR P22- SCH 80. ASME B36.10 PLAIN ENDS (QUANTITIES UNIT: M)" ndi seti ya ma specifications aukadaulo omwe amafotokoza mapaipi achitsulo cha alloy. Tiyeni tiwafufuze limodzi ndi limodzi:

CHITSULO CHA ALLOY CHIPIPA HT:
"PIPE" amatanthauza chitoliro, ndipo "ALLOY STEEL" amatanthauza chitsulo chosakanikirana. Chitsulo chosakanikirana ndi chitsulo chomwe chili ndi chinthu chimodzi kapena zingapo zosakaniza (monga chromium, molybdenum, tungsten, ndi zina zotero) ndipo chili ndi zinthu zabwino kwambiri monga kukana kutentha kwambiri, kukana dzimbiri komanso mphamvu.

"HT" nthawi zambiri imatanthauza zofunikira pa kutentha kwambiri, zomwe zikusonyeza kuti chitsulo cha chitolirochi ndi choyenera malo otentha kwambiri.

ASTM A335 GR P22:
Iyi ndi kufotokozera kwa muyezo ndi mtundu wa zipangizo za chitoliro.

ASTM A335ndi muyezo wopangidwa ndi American Society for Testing and Materials (ASTM) wa mapaipi achitsulo chosasunthika, makamaka pa malo otentha kwambiri komanso opanikizika kwambiri.
GR P22 ndiye mtundu wa zinthu zomwe zili mu muyezo uwu, pomwe "P22" imasonyeza kapangidwe ka mankhwala ndi zofunikira pakugwira ntchito kwa chitolirocho. Chitsulo cha aloyi cha P22 nthawi zambiri chimakhala ndi zinthu za chromium (Cr) ndi molybdenum (Mo), chimakhala ndi mphamvu yabwino yotentha komanso kukana dzimbiri, ndipo chimayenera kugwiritsidwa ntchito m'malo otentha kwambiri.
SCH 80:
Izi zikutanthauza kukula kwa khoma la chitoliro, ndipo "SCH" ndi chidule cha "Ndondomeko".

SCH 80 imatanthauza kuti makulidwe a khoma la chitolirocho ndi okhuthala pang'ono ndipo amatha kupirira kupsinjika kwakukulu kwamkati. Pa mapaipi a SCH 80, makulidwe ake a khoma ndi akulu pakati pa mapaipi a mulifupi womwewo, zomwe zingawonjezere mphamvu yake yonyamula kupanikizika komanso kukana kugwedezeka.
ASME B36.10:
Uwu ndi muyezo wopangidwa ndi American Society of Mechanical Engineers (ASME) womwe umatchula kukula, mawonekedwe, kulekerera, kulemera ndi zofunikira zina za mapaipi achitsulo. B36.10 imayang'ana makamaka m'mimba mwake wakunja, makulidwe a khoma ndi magawo ena a mapaipi opanda msoko achitsulo cha kaboni ndi alloy ndi mapaipi olumikizidwa kuti atsimikizire kuti zinthu zamapaipi zimakhazikika komanso zimakhala zofanana.

MAPETO OPANDA CHINSINSI:
"Mapeto Opanda Chingwe" amatanthauza mapaipi opanda machining kapena malekezero olumikizirana, nthawi zambiri okhala ndi malo odulidwa osalala. Poyerekeza ndi mapaipi okhala ndi maulumikizidwe olumikizidwa ndi ulusi kapena opindika, mapaipi opanda chingwe nthawi zambiri amagwiritsidwa ntchito polumikizirana komwe kumafunika maulumikizidwe olumikizidwa.

CHIGAWO CHA ZINTHU ZOFUNIKA: M:
Izi zikusonyeza kuti gawo loyezera la chinthucho ndi "mita", ndiko kuti, kuchuluka kwa chitoliro kumayesedwa mu mamita, osati zidutswa kapena mayunitsi ena.

Chitoliro chomwe chafotokozedwa mu kufotokozeraku ndi chitoliro chachitsulo chotentha kwambiri chomwe chimakwaniritsa muyezo wa ASTM A335 GR P22, chokhala ndi makulidwe a khoma la SCH 80 ndipo chimakwaniritsa muyezo wa kukula kwa ASME B36.10. Malekezero a chitolirocho ndi osalala (opanda ulusi kapena ma flange), kutalika kwake kumayesedwa m'mamita, ndipo ndi koyenera kugwiritsa ntchito mapaipi omwe ali ndi kutentha kwambiri, kuthamanga kwambiri komanso malo owononga.
