"PIPE Alloy STEEL HTI-ASTM A335 GR P22- I-SCH 80. I-ASME B36.10 I-PLAIN ENDS (INYUNYI YOBUNINGI : M)" isethi yezicaciso zobuchwepheshe ezichaza amapayipi ensimbi ye-alloy. Ake siwahlaziye ngalinye ngalinye:

I-PIPE ALLOY STEEL HT:
"IPIPE" isho ipayipi, futhi "ALLOY SteEL" isho insimbi yengxubevange. Insimbi ye-alloy iyinsimbi equkethe i-alloying eyodwa noma ngaphezulu izakhi (njenge-chromium, i-molybdenum, i-tungsten, njll.) futhi inezici ezinhle kakhulu ezifana nokumelana nokushisa okuphezulu, ukumelana nokugqwala namandla.

"HT" ngokuvamile ibhekisela ezidingweni zokushisa okuphezulu, okubonisa ukuthi le nsimbi yepayipi ifanele izindawo zokushisa eziphezulu.

I-ASTM A335 GR P22:
Lena incazelo yezinga kanye nebanga lezinto zamapayipi.

I-ASTM A335iyindinganiso ethuthukiswe yi-American Society for Testing and Materials (ASTM) yamapayipi ensimbi angenamthungo, ikakhulukazi izinga lokushisa eliphezulu kanye nezindawo ezinengcindezi ephezulu.
I-GR P22 yibanga elithile lempahla elingaphansi kwaleli zinga, lapho i-"P22" ikhombisa ukwakheka kwamakhemikhali nezimfuneko zokusebenza kwento yepayipi. Insimbi ye-P22 alloy ngokuvamile iqukethe izakhi ze-chromium (Cr) kanye ne-molybdenum (Mo), inamandla amahle okushisa okuphezulu nokumelana nokugqwala, futhi ifanele indawo yokushisa ephezulu.
I-SCH 80:
Lokhu kubhekisela ebangeni lokujiya kodonga lwepayipi, futhi "SCH" isifinyezo "seSheduli".

I-SCH 80 isho ukuthi ubukhulu bodonga lwepayipi bukhulu kakhulu futhi bungakwazi ukumelana nokucindezela okukhulu kwangaphakathi. Kumapayipi e-SCH 80, ukushuba kodonga bukhulu phakathi kwamapayipi anobubanzi obufanayo, okungakhuphula amandla ayo okuthwala ingcindezi kanye nokumelana nomthelela.
I-ASME B36.10:
Leli izinga elithuthukiswe yi-American Society of Mechanical Engineers (ASME) elicacisa usayizi, umumo, ukubekezelela, isisindo kanye nezinye izidingo zamapayipi ensimbi. I-B36.10 iqondise ngokukhethekile ububanzi bangaphandle, ukujiya kodonga namanye amapharamitha ensimbi ye-carbon steel kanye ne-alloy steel amapayipi angenamthungo namapayipi ashiselwe ukuze kuqinisekiswe izinga kanye nokuvumelana kwemikhiqizo yamapayipi.

I-PALAIN IPHELA:
"Iziphetho Ezingenalutho" zibhekisela kumapayipi angenawo imishini noma iziphetho zokuxhuma, ngokuvamile anezindawo ezisikiwe ezibushelelezi. Uma kuqhathaniswa namapayipi anezintambo ezinezintambo noma ezine-flanged, amapayipi angenalutho ngokuvamile asetshenziselwa izinhlelo zokusebenza lapho uxhumano oluhlanganisiwe ludingeka khona.

QUANTITIES UNIT : M:
Lokhu kubonisa ukuthi iyunithi yokulinganisa yomkhiqizo "imitha", okungukuthi, inani lepayipi likalwa ngamamitha, hhayi izingcezu noma amanye amayunithi.

Ipayipi elichazwe kule ncazelo ipayipi lensimbi ye-alloy ephezulu lokushisa elihlangabezana nezinga le-ASTM A335 GR P22, elinogqinsi lwe-SCH 80 futhi lihlangabezana nosayizi ojwayelekile we-ASME B36.10. Iziphetho zepayipi zicacile (akukho ntambo noma ama-flanges), ubude bulinganiswa ngamamitha, futhi ifaneleka kumasistimu amapayipi ekushiseni okuphezulu, ukucindezela kanye nezindawo ezibolayo.
