Mā ēnei āhuatanga kaNgā paipa ASTM A106pai mōngā tipu hiko, ngā tipu hinu-matū, ngā whare whakapai hinu, ngā kohua, me ngā pūnaha paipa pēhanga teitei.

Ngā Tohu ASTM A106

E toru ngā taumata o ngā paipa ASTM A106:Taumata A, Taumata B, me Taumata CHe āhuatanga matū me ngā āhuatanga ā-pūkaha motuhake tō ia momo mō ngā āhuatanga ratonga rerekē.

Tau	Waro Mōrahi (C)	Manganēhi (Mn)	Kaha Hua (MPa)	Kaha Kume (MPa)	Te Whakamahinga Noa
A	0.25%	0.27–0.93%	≥ 205	≥ 330	Ngā paipa pēhanga iti, pāmahana iti
B	0.30%	0.29–1.06%	≥ 240	≥ 415	Ratonga pāmahana teitei tino noa, whānui
C	0.35%	0.29–1.06%	≥ 275	≥ 485	Ngā taiao pāmahana teitei, pēhanga teitei, tono nui

Ngā Ahu me ngā Rahi

He whānuitia ngā rahi paipa ingoa (NPS) e wātea ana ngā paipa ASTM A106 mai i te 1/8” ki te 48”, me te matotoru o te pakitara i runga i ngā whakaritenga ASME B36.10M, pērā i te SCH40 (STD), SCH80 (XH), SCH160.

Ko ngā diameter iti (< 1½”) ka taea te whakaoti wera, te tuhi matao rānei

Ko ngā diameter nui ake (≥ 2 inihi) ka oti te whakaoti ki te wera.

Ko te roa he 6–12 mita te nuinga, ka whakaritea rānei kia rite ki ngā whakaritenga o te kaupapa

Ngā Āhuatanga Mīhini

Kua hangaia ngā paipa ASTM A106 mō ngā tono pāmahana teitei, e tuku ana i:

Te kaha kume me te kaha tuku

Te pumau wera tino pai

He pai te ngāwari me te ngāwari whakarewa

Whakamātautau pānga kōwhiringa mō ngā āhuatanga kino

Tau	Kaha Hua (MPa)	Kaha Kume (MPa)	Te roa (%)

Ngā Taupānga Noa

Ngā paipa ASTM A106 tuituie whakamahia whānuitia ana puta noa i ngā ahumahi, tae atu ki:

Ngā Whare Hiko: Ngā paipa mamaoa, ngā poiha, ngā whakawhiti wera

Matū Kete me te Whare Whakamaeneene: Ngā paipa matū pāmahana teitei, pēhanga teitei

Hinu me te Hau: Ngā paipa kawe hau māori me te hinu

Ahumahi: Ngā tipu matū, te hanga kaipuke, ngā oko pēhanga, ngā paipa ahumahi

Nā te kaha ki te tu atu i te pāmahana tiketike, te pēhanga teitei, me ngā taiao waikura, he mea pai ēnei mō ngā kaupapa hangarau o te ao katoa.

He aha i whiriwhiri ai i ngā paipa ASTM A106 Tuitui?

Hanganga maeneeneka whakarite i te haumaru me te pono i roto i ngā pūnaha pēhanga teitei

Ngā māka maha(A/B/C) ka taea te whakarite i te kaha me te mahi pāmahana

Whānui te whānuitanga o te rahie kapi ana i ngā diameters iti ki ngā diameters tino nui
