ASME SA333 Gr. 6 Ubushushu obuphantsi Umbhobho wentsimbi ongenamthungo

I-ASTM A333Gr6/ASME SA333Gr6 Umbhobho wentsimbi wobushushu obuphantsi
iimfuno zemveliso
IBakala: A333Gr.6 / SA333Gr.6
Umgangatho: ASTM A333 / ASME SA333

inkqubo yokuvelisa umbhobho wentsimbi
Inkqubo yokuveliswa kweemibhobho zetsimbi iphunyezwa ngokubhekiselele kwinkqubo yeteknoloji ye-20G yensimbi.

Umbhobho wentsimbi ukutenxa komgangatho kunye nokutenxa ubunzima
Ukutenxa kwidayamitha yangaphandle: Ukutenxa kwedayamitha yangaphandle yombhobho wentsimbi kuya kuhlangabezana neemfuno

Uluhlu lwedayamitha(mm)	10.3~48.3	>48.3~114.3	>114.3~219.1	>219.1~406.4
Ukutenxa kwidayamitha(mm)	-0.8~+0.4	-0.8~+0.8	-0.8~+1.6	-0.8~+2.4

Ukutenxa kobunzima bodonga: -8% ~ + 12%.
Ukutenxa ubunzima: -3.5% ~ + 10%.
Ukuchaneka kobude obusisigxina: ngokweemfuno zomsebenzisi.
Ukuthe tye: ≤1.5mm / m.
Ubume bokuhanjiswa kunye nenkqubo yokunyanga ukushisa kombhobho wensimbi
Umbhobho wentsimbi uhanjiswa kwimeko yokuphathwa kobushushu obuqhelekileyo.
Inkqubo yonyango yokushisa eqhelekileyo yemveliso egqityiweyo yile: 900 ° C ~ 930 ° C kwi-5 ~ 15min, ukupholisa umoya.

Iimpawu zomatshini wemibhobho yentsimbi
Iimpawu zokuqina
Iimpawu ezinqabileyo zemibhobho yensimbi ziya kuhlangabezana neemfuno ze-ASTM A333Gr6.
Kwimibhobho yentsimbi enobungqingqwa bodonga lwegama ≤ 8mm, isampuli yovavanyo lwe-tensile yi-longitudinal strip test specimen enobubanzi obuyi-12.5mm kunye nomgama wegeyiji oyi-50mm. Kwimibhobho yentsimbi enobukhulu obuqhelekileyo bodonga ≥8mm, umzekelo ongqukuva onegeyiji yomgama we-4D ungasetyenziswa.

Uvavanyo lokucaba
Into etyumzayo yi-0.07.

Ukusebenza kwempembelelo
Ibhetshi nganye yemibhobho yentsimbi enobubanzi obungaphandle obungaphezulu kwe-21.3mm iya kuhlolwa ukusebenza kwempembelelo ye-Akv.

Ubungakanani bomzekelo(mm)		3	3.3	4	5	6	6.67	7	7.5	8	9	10
Akv(J)	≥ 5	≥ 6	≥ 7	≥ 8	≥ 9	≥11	≥ 12	≥13	≥ 14	≥16	≥17	≥18

Ubushushu bovavanyo lwempembelelo
Xa ubukhulu bomzekelo wempembelelo encinci bufikelela okanye budlula i-80% yobukhulu bokwenene bombhobho wentsimbi, ubushushu bovavanyo yi-45 ° C.
Xa ubukhulu bomlinganiselo omncinci wempembelelo yempembelelo bungaphantsi kwe-80% yobukhulu bokwenene bombhobho wensimbi, ubukhulu bomfanekiso kufuneka bube bukhulu ngokusemandleni. Ubushushu bovavanyo lwaluyi-55 ° C.


Uvavanyo lokuqina (kuphela xa kufunwa ikhontrakthi)
Ukuba ikhontrakthi idinga ukuba ubunzima buvavanywe ngokuhambelana nomgangatho we-NACE MR-0175, isiqwenga sovavanyo malunga ne-20-30 mm ubude siya kuthathwa kwibhetshi nganye yeepayipi zensimbi, kwaye ubunzima buya kuba ngaphantsi kwe-22HRc.
