GB/T9948Ko te paipa maitai kore hononga mō te pakaru hinu he paipa kore hononga e tika ana mō ngā ngongo oumu, ngā whakawhiti wera me ngā paipa i roto i ngā whare hanga hinu. Ka whakamahia ngā paipa maitai hanganga waro kounga teitei, te maitai hanganga koranu me te maitai ātete wera kowiri tira, he paipa pakari kore hononga pēhanga teitei hei hanga i ngā paipa poiha mamaoa pēhanga teitei me runga ake. Ka mahi ēnei paipa poiha i raro i te pāmahana me te pēhanga teitei, ā, ka pāngia ngā paipa e te paowa pāmahana teitei. Ka puta hoki te waikura me te waikura i raro i te mahi a te hau me te kohu wai. Nō reira, me whai kaha roa, ātete waikura teitei, me te pumau pai o te whakahaere o ngā paipa maitai. Haunga te whakarite i te hanganga matū me ngā āhuatanga miihini, me whakahaere hoki e ngā paipa poiha pēhanga teitei te whakamātautau pēhanga waipēhi takitahi, tae atu ki ngā whakamātautau whakawhanui me te whakatārewatanga. Ka tukuna ngā paipa kore hononga pēhanga teitei i roto i te āhua tukatuka wera.
Ngā tikanga whakaputa me te hanga o ngā paipa pakaru hinu:

① Ko te tikanga, ko te pāmahana ratonga o ngā paipa rino kore-hono kei raro iho i te 450°C. Ko te nuinga o ngā paipa o te whare he mea hanga ki te Nama 10, Nama 20,12CrMo, 15CrMo, 12CrlMo, 12CrlMoV, 12Cr5MoI, 12Cr9MoI, ngā paipa hurihuri-wera, ngā paipa tōia-matao rānei.

② He maha ngā wā ka pāngia ngā paipa rino kore-whakarewa paerewa GB9948 e ngā āhuatanga pāmahana teitei me te pēhanga teitei ina whakamahia. Ka waikura, ka waikura hoki ngā paipa i raro i te mahi a te hau paowa pāmahana teitei me te kohu wai. Me whai kaha roa, ātete teitei ki te waikura me te waikura, me te pumau hoki o te hanganga o ngā paipa rino.

whakamahi:

① Ko te tikanga, ko ngā paipa rino tuitui e whakamahia ana mō te hanga paipa pakitara wai, paipa wai kohua, paipa mamaoa wera rawa, paipa mamaoa wera rawa mō ngā kohua tereina, paipa paowa nui me te iti me ngā paipa pereki āwhata, me ētahi atu.

②Ko te paipa maitai tui GB9948 e whakamahia ana mō te hanga ngongo whakamahana nui, ngongo whakamahana anō, ngongo ārahi hau, ngongo mamaoa matua, me ētahi atu mō ngā kohua pēhanga teitei me te pēhanga tino teitei.

E ai ki te mahi pāmahana teitei, ka wehea ngā paipa maitai tuitui paerewa GB9948 ki ngā paipa poiha whānui me ngā paipa poiha pēhanga teitei. Ahakoa he paipa poiha whānui, he paipa poiha pēhanga teitei rānei, ka taea te wehewehe ki ngā paipa maitai rerekē e ai ki ngā whakaritenga whakamahinga rerekē.
Paipa rino kore hononga GB/T9948, te diameter o waho 10~426mm, te matotoru o te pakitara 1.5~26mm. Ko te diameter o waho me te matotoru o te pakitara o ngā ngongo mamaoa wera rawa, ngā ngongo paowa nui, ngā ngongo paowa iti me ngā ngongo pereki āwhata e whakamahia ana i roto i ngā poiha waka tereina kua tohua kētia.

Te kounga o te āhua: Kāore e whakaaetia ngā kapiti, ngā kopa, ngā takai, ngā papaki, ngā wehewehenga me ngā raina huruhuru ki ngā mata o roto, o waho hoki o ngā paipa rino. Me tango katoa ēnei hapa. Kaua te hohonu o te horoi e neke ake i te rerekētanga kino o te matotoru pakitara ingoa, ā, kaua te matotoru tūturu o te pakitara i te wāhi horoi e iti iho i te matotoru pakitara iti rawa e whakaaetia ana.
