Chiyambi cha malonda
ASTM A333Gr6/ASME SA333Gr6 Chitoliro chotsika chachitsulo
zofunika mankhwala
Gulu: A333Gr.6 / SA333Gr.6
Standard: ASTM A333 / ASME SA333
ndondomeko yopanga chitoliro chachitsulo
Njira yopangira mipope yachitsulo ikugwiritsidwa ntchito ponena za teknoloji ya 20G zitsulo.
Kupatuka kwa chitoliro chachitsulo ndi kuwonda
Kupatuka kwapakati pakunja: Kupatuka kwakunja kwa chitoliro chachitsulo kudzakwaniritsa zofunikira

Kulondola kwautali wokhazikika: malinga ndi zofunikira za ogwiritsa ntchito.
Kuwongoka: ≤1.5mm / m.
Kutumiza udindo ndi kutentha mankhwala ndondomeko ya zitsulo chitoliro
Chitoliro chachitsulo chimaperekedwa mu chikhalidwe chokhazikika cha kutentha.
The normalized kutentha mankhwala ndondomeko yomalizidwa ndi: 900 ° C ~ 930 ° C kwa 5 ~ 15min, mpweya kuzirala.
Zimango katundu wa zitsulo mapaipi
Makoma katundu
Kukhazikika kwa mipope yachitsulo kudzakwaniritsa zofunikira za ASTM A333Gr6.
Kwa mapaipi achitsulo okhala ndi makulidwe a khoma mwadzina ≤ 8mm, choyeserera choyezera chitsulo ndi chitsanzo choyesera chotalikirapo chokhala ndi m'lifupi mwake 12.5mm ndi mtunda wa geji 50mm. Kwa mapaipi achitsulo okhala ndi makulidwe mwadzina ≥8mm, chitsanzo chozungulira chokhala ndi mtunda wa 4D chingagwiritsidwe ntchito.
Mayeso osalala
Chinthu chophwanyidwa ndi 0.07.
Kuchita kwamphamvu
Gulu lililonse la mapaipi achitsulo okhala ndi mainchesi akunja opitilira 21.3mm aziwunikiridwa kuti agwire ntchito ya Akv.

Impact test kutentha
Pamene makulidwe a mawonekedwe ang'onoang'ono amafika kapena kupitirira 80% ya makulidwe enieni a chitoliro chachitsulo, kutentha kwa mayeso ndi -45 ° C.
Pamene makulidwe a chitsanzo chaching'ono chaching'ono ndi chocheperapo 80% cha makulidwe enieni a chitoliro chachitsulo, makulidwe a chitsanzo ayenera kukhala aakulu momwe angathere. Kutentha kwa mayeso kunali -55 ° C.
Kuyesa kuuma (pokhapokha pakufunika ndi mgwirizano)
Ngati mgwirizano umafuna kuuma kuyesedwa molingana ndi muyezo wa NACE MR-0175, chidutswa choyesera cha pafupifupi 20-30 mm kutalika chidzatengedwa kuchokera ku gulu lililonse la mapaipi achitsulo, ndipo kuuma kwake kudzakhala kosakwana 22HRc.
