"Insimbi ye-Alloy yamapayipi HTI-ASTM A335 GR P22- SCH 80. ASME B36.10 PLAIN ENDS (QUANTITIES UNIT: M)" iyisethi yezincazelo zobuchwepheshe ezichaza amapayipi ensimbi e-alloy. Ake siwahlaziye ngamunye ngamunye:

Insimbi ye-Alloy yepayipi HT:
"IPIPE" isho ipayipi, kanti "I-ALLOY STEEL" isho insimbi ye-alloy. Insimbi ye-alloy insimbi equkethe into eyodwa noma ngaphezulu yokuhlanganisa (njenge-chromium, i-molybdenum, i-tungsten, njll.) futhi inezakhiwo ezinhle kakhulu njengokumelana nokushisa okuphezulu, ukumelana nokugqwala kanye namandla.

I-"HT" ivame ukubhekisela ezidingweni zokushisa okuphezulu, okubonisa ukuthi le nsimbi yamapayipi ifanelekela izindawo zokushisa okuphezulu.

I-ASTM A335 GR P22:
Lena incazelo yezinga kanye nezinga lezinto zombhobho.

I-ASTM A335iyindinganiso ethuthukiswe yi-American Society for Testing and Materials (ASTM) yamapayipi ensimbi angenamthungo, ikakhulukazi ezindaweni ezinokushisa okuphezulu kanye nokucindezela okuphezulu.
I-GR P22 iyizinga lezinto ezithile ngaphansi kwaleli zinga, lapho i-"P22" ikhombisa ukwakheka kwamakhemikhali nezidingo zokusebenza kwezinto zamapayipi. Insimbi ye-alloy ye-P22 ivame ukuqukethe izakhi ze-chromium (Cr) kanye ne-molybdenum (Mo), inamandla amahle okushisa okuphezulu kanye nokumelana nokugqwala, futhi ifanelekela izindawo zokushisa okuphezulu.
I-SCH 80:
Lokhu kubhekisela ebangeni lobukhulu bodonga lwepayipi, kanti elithi "SCH" liyisifinyezo segama elithi "Schedule".

I-SCH 80 isho ukuthi ubukhulu bodonga lwepayipi bukhulu kakhulu futhi bungamelana nokucindezela okuphezulu kwangaphakathi. Kumapayipi e-SCH 80, ubukhulu bodonga bukhulu phakathi kwamapayipi anobubanzi obufanayo, okungandisa amandla awo okuthwala ukucindezela kanye nokumelana nokushaya.
I-ASME B36.10:
Lena indinganiso eyasungulwa yi-American Society of Mechanical Engineers (ASME) echaza ubukhulu, ukuma, ukubekezelelana, isisindo kanye nezinye izidingo zamapayipi ensimbi. I-B36.10 ihlose ngqo ububanzi bangaphandle, ukujiya kodonga kanye nezinye izilinganiso zamapayipi angenamthungo ensimbi yekhabhoni kanye nensimbi ye-alloy kanye namapayipi ahlanganisiwe ukuqinisekisa ukwenziwa okujwayelekile kanye nokuvumelana kwemikhiqizo yamapayipi.

IZIPHETHO EZINGACACILE:
"Ama-Plain Ends" abhekisela kumapayipi angenazo iziphetho zomshini noma zokuxhuma, ngokuvamile anezindawo ezibushelelezi zokusika. Uma kuqhathaniswa namapayipi anokuxhumeka okunezintambo noma okugoqekile, amapayipi avamile asetshenziswa ezindaweni lapho kudingeka khona ukuxhumeka okuhlanganisiwe.

IYUNITHI YEZINANI: M:
Lokhu kubonisa ukuthi iyunithi yokulinganisa yomkhiqizo "yimitha", okungukuthi, inani lepayipi lilinganiswa ngamamitha, hhayi izingcezu noma amanye amayunithi.

Ipayipi elichazwe kule ncazelo liyipayipi lensimbi elihlanganisiwe elinokushisa okuphezulu elihlangabezana nezindinganiso ze-ASTM A335 GR P22, elinobukhulu bodonga obuyi-SCH 80 futhi lihlangabezana nezindinganiso zobukhulu be-ASME B36.10. Iziphetho zepayipi zilula (azikho izintambo noma ama-flange), ubude bulinganiswa ngamamitha, futhi lifanele izinhlelo zamapayipi ezindaweni zokushisa okuphezulu, ingcindezi kanye nezindawo ezigqwalayo.
