"PIPE ALOY zitsulo HTASTM A335 GR P22- SCH80. ASME B36.10 PLAIN ENDS (QUANTITIES UNIT : M)" ndi mndandanda wazinthu zomwe zimalongosola mapaipi achitsulo cha alloy. Tiyeni tiwunike m'modzim'modzi:

PIPE ALOY ZINYENGE HT:
"PIPE" amatanthauza chitoliro, ndipo "Alloy zitsulo" amatanthauza chitsulo cha alloy. Chitsulo cha aloyi ndi chitsulo chomwe chimakhala ndi chinthu chimodzi kapena zingapo (monga chromium, molybdenum, tungsten, etc.) ndipo chimakhala ndi zinthu zabwino kwambiri monga kukana kutentha kwambiri, kukana kwa dzimbiri ndi mphamvu.

"HT" nthawi zambiri imatanthawuza zofunikira za kutentha kwambiri, zomwe zimasonyeza kuti chitoliro ichi ndi choyenera kumadera otentha kwambiri.

ASTM A335 GR P22:
Izi ndi kufotokoza muyezo ndi kalasi ya zipangizo chitoliro.

Chithunzi cha ASTM A335ndi muyezo wopangidwa ndi American Society for Testing and Materials (ASTM) wamapaipi azitsulo a aloyi osasunthika, makamaka kutentha kwambiri komanso malo othamanga kwambiri.
GR P22 ndiye giredi yeniyeni ya zinthu zomwe zili pansi pa mulingo uwu, pomwe "P22" imawonetsa kapangidwe kake ndi zofunikira pakuchita kwa chitoliro. Chitsulo cha P22 alloy nthawi zambiri chimakhala ndi zinthu za chromium (Cr) ndi molybdenum (Mo), chimakhala ndi mphamvu zotentha kwambiri komanso kukana dzimbiri, ndipo chimakhala choyenera kumadera otentha kwambiri.
Mtengo wa 80:
Izi zikutanthauza makulidwe a khoma la chitoliro, ndipo "SCH" ndi chidule cha "Ndandanda".

SCH 80 imatanthawuza kuti makulidwe a khoma la chitoliro ndi wandiweyani ndipo amatha kupirira kuthamanga kwambiri mkati. Kwa mapaipi a SCH 80, makulidwe ake a khoma ndiakuluakulu pakati pa mapaipi a mainchesi omwewo, omwe amatha kukulitsa mphamvu yake yonyamula mphamvu komanso kukana.
ASME B36.10:
Uwu ndi muyeso wopangidwa ndi American Society of Mechanical Engineers (ASME) womwe umatchula kukula, mawonekedwe, kulolerana, kulemera ndi zofunikira zina zamapaipi achitsulo. B36.10 makamaka imayang'ana m'mimba mwake, makulidwe a khoma ndi magawo ena azitsulo za kaboni ndi aloyi zitsulo zopanda msokonezo ndi mapaipi otsekemera kuti atsimikizire kukhazikika komanso kusasinthika kwazinthu zamapaipi.

ZOPHUNZITSA ZIMTHA:
"Plain Ends" amatanthauza mapaipi opanda makina kapena malekezero olumikizira, nthawi zambiri okhala ndi malo odulidwa osalala. Poyerekeza ndi mapaipi okhala ndi ulusi kapena flanged, mapaipi osavuta amagwiritsidwa ntchito ngati ma welded amafunikira.

QUANTITIES UNIT : M:
Izi zikuwonetsa kuti gawo la kuyeza kwa mankhwalawa ndi "mita", ndiko kuti, kuchuluka kwa chitoliro kumayesedwa mu mita, osati zidutswa kapena mayunitsi ena.

Chitoliro chomwe chafotokozedwa m'mafotokozedwe awa ndi chitoliro chachitsulo chotentha kwambiri chomwe chimakumana ndi muyezo wa ASTM A335 GR P22, wokhala ndi makulidwe a khoma la SCH 80 ndikukwaniritsa kukula kwa ASME B36.10. Malekezero a chitoliro ndi omveka (palibe ulusi kapena flanges), kutalika kwake kumayesedwa mu mamita, ndipo ndi koyenera kwa machitidwe a mapaipi mu kutentha kwakukulu, kuthamanga ndi malo owononga.
