Isingeniso somkhiqizo
I-ASTM A333Gr6/ASME SA333Gr6 Ipayipi lensimbi lokushisa eliphansi
izidingo zomkhiqizo
Ibanga: A333Gr.6 / SA333Gr.6
Okujwayelekile: ASTM A333 / ASME SA333
inqubo yokukhiqiza ipayipi lensimbi
Inqubo yokukhiqiza yamapayipi ensimbi isetshenziswa ngokubhekisela ohlelweni lobuchwepheshe lwensimbi engu-20G.
Ukuchezuka kobukhulu bepayipi lensimbi nokuchezuka kwesisindo
Ukuchezuka kobubanzi obungaphandle: Ukuchezuka kobubanzi obungaphandle bepayipi lensimbi kuzohlangabezana nezidingo

Ukuchezuka kokuqina kodonga: -8% ~ + 12%.
Ukuchezuka kwesisindo: -3.5% ~ + 10%.
Ukunemba kobude obungaguquki: ngokuya ngezidingo zomsebenzisi.
Ukuqondile: ≤1.5mm / m.
Isimo sokulethwa kanye nenqubo yokwelashwa kokushisa kwepayipi lensimbi
Ipayipi lensimbi lilethwa esimweni esijwayelekile sokuphathwa kokushisa.
Inqubo evamile yokwelapha ukushisa yomkhiqizo oqediwe yile: 900 ° C ~ 930 ° C i-5 ~ 15min, ukupholisa umoya.
Izakhiwo zemishini zamapayipi ensimbi
Izakhiwo ze-tensile
Izakhiwo eziqinile zamapayipi ensimbi zizohlangabezana nezidingo ze-ASTM A333Gr6.
Emapayipini ensimbi anogqinsi olujwayelekile lodonga ≤ 8mm, isampula yokuhlola eqinile iyisampula yokuhlolwa kwe-longitudinal strip enobubanzi obungu-12.5mm kanye nebanga legeji elingu-50mm. Emapayipini ensimbi anogqinsi olujwayelekile lodonga ≥8mm, isampula esiyindilinga esinebanga lokukala elingu-4D singasetshenziswa.
Ukuhlolwa kokucaba
Isici esicindezelayo singu-0.07.
Ukusebenza okunomthelela
Iqoqo ngalinye lamapayipi ensimbi anobubanzi obungaphandle obungaphezu kuka-21.3mm lizohlolwa ukusebenza komthelela we-Akv.

Izinga lokushisa lokuhlola lomthelela
Lapho ubukhulu besampula yomthelela yosayizi omncane bufinyelela noma budlula u-80% wobukhulu bangempela bepayipi lensimbi, izinga lokushisa lokuhlola lingu-45 ° C.
Uma ubukhulu besampula yomthelela yosayizi omncane bungaphansi kuka-80% wogqinsi lwangempela lwepayipi lensimbi, ukujiya kwesifanekiso kufanele kube kukhulu ngangokunokwenzeka. Izinga lokushisa lokuhlola lalingu -55 ° C.
Ukuhlolwa kokuqina (kuphela uma kudingwa yinkontileka)
Uma inkontileka idinga ukuthi ubulukhuni buhlolwe ngokuhambisana nezinga le-NACE MR-0175, ucezu lokuhlola olucishe lube ngu-20-30 mm ubude luzothathwa kubhetshi ngayinye yamapayipi ensimbi, futhi ukuqina kuyoba ngaphansi kuka-22HRc.
