I-China Ikhwalithi ephezulu yensimbi yesakhiwo se-carbon, i-alloy structural steel nensimbi engamelana nokushisa okungagqwali ipayipi elingenamthungo lamapayipi okubhayela isitimu ngaphansi kwengcindezi ephezulu nangaphezulu kwengcindezi Umkhiqizi Nomphakeli

Insimbi yekhwalithi ephezulu ye-carbon structural, i-alloy structural steel kanye nensimbi ekwazi ukumelana nokushisa okungenasici ipayipi elingenamthungo lamapayipi okubhayela isitimu ngaphansi kwengcindezi ephezulu nangaphezulu

Insimbi yesakhiwo sekhabhoni yekhwalithi ephezulu, insimbi yesakhiwo sealloy kanye nensimbi engamelana nokushisa okungenasici umfutho ophezulu wepayipi elingenamthungo lamapayipi obhayela wesitimu ngaphansi kwengcindezi ephezulu nangaphezulu kwengcindezi Isithombe esifakiwe

Incazelo emfushane:

Indlela yokukhiqiza:

(1) Okujwayelekile kwe-GB9948 ipayipi lensimbi engenamthungo izinga lokushisa lingaphansi kuka-450 ℃, ipayipi lasekhaya lenziwa ikakhulukazi ngo-no. 10, 20 carbon bonded steel ipayipi elishisayo eligoqiwe noma ipayipi elidonsa abandayo.

②GB9948 ipayipi lensimbi engenamthungo livame ukusetshenziswa ezimweni zokushisa eziphakeme kanye nezimo zengcindezi ephezulu, ipayipi ngaphansi kwesenzo segesi ephezulu yokushisa yokushisa kanye nomhwamuko wamanzi, i-oxidation kanye nokugqwala kuzokwenzeka.Ipayipi lensimbi liyadingeka ukuze libe namandla ahlala isikhathi eside, ukumelana nokugqwala okuphezulu kwe-oxidation kanye nokuzinza okuhle kwe-microstructure.

(2) sebenzisa:

(1) Ipayipi elivamile le-GB9948 lensimbi elingenamthungo lisetshenziselwa ikakhulukazi ukwakha ipayipi lodonga elipholiswe ngamanzi, ipayipi lamanzi abilayo, ipayipi lesitimu esishisa kakhulu, ipayipi lesitimela esishisayo esishisayo, ipayipi lentuthu elikhulu nelincane kanye nepayipi lezitini le-arch.

②GB9948 ithubhu yensimbi engenamthungo isetshenziswa kakhulu ukwenza ishubhu yokushisa okuphezulu, ishubhu yokufudumeza kabusha, ipayipi, ipayipi lesitimu esikhulu nokunye komfutho ophezulu kanye nobhayela onengcindezi ephezulu kakhulu.

I-GB9948 ithubhu yensimbi engenamthungo ngokusho kokusebenza kwezinga lokushisa eliphezulu ihlukaniswe ngamashubhu kabhayela ojwayelekile kanye neshubhu elibhayela elinomfutho omkhulu.Kungakhathaliseki ukuthi ishubhu eliboyela elivamile noma ishubhu elinomfutho omkhulu lingahlukaniswa libe amashubhu ensimbi ahlukahlukene ngokuvumelana nezidingo ezahlukene zokusetshenziswa kwawo.

Imininingwane kanye nekhwalithi yokubukeka

(1)GB3087-2008 “Ipayipi Lensimbi Elingenamthungo kubhayela womfutho ophansi nophakathi” .Kodwa-ke, ububanzi obungaphandle nobukhulu bodonga bepayipi le-steam elishisa kakhulu, ipayipi elikhulu lentuthu, ipayipi elincane lentuthu kanye nepayipi lesitini se-arch. ezisetshenziswa kubhayela wesitimela zibalulwe ngenye indlela.

(2)GB5310-2008 “Seamless Steel Tube for High pressure Boiler” hot igingqe ipayipi ububanzi 22 ~ 530mm, udonga ukujiya 20 ~ 70mm.Abandayo adonswe (kubanda rolling) tube ububanzi 10 ~ 108mm, udonga ukujiya 2.0 ~ 13.0mm.

(3)GB3087-2008 "ithubhu lensimbi engenamthungo kubhayela wengcindezi ephansi nephakathi" kanye ne-GB5310-2008 "ithubhu lensimbi engenamthungo lebhayela elinomfutho ophakeme".Ikhwalithi yokubukeka: ukuqhekeka, ukugoqa, ukugoqa, izibazi, ukuhlukaniswa kanye nemibimbi akuvunyelwe indawo engaphakathi nengaphandle yepayipi lensimbi.Lokhu kukhubazeka kufanele kuqedwe ngokuphelele.Ukujula kokususa akumele kudlule ukuchezuka okunegethivu Ukujiya kodonga okulinganiselwe, kanye nobukhulu bangempela bodonga endaweni evulekile akumele bube ngaphansi kobukhulu obuncane obuvumelekile bodonga.

Isidingo Sokuhlola

Ukuhlolwa kwe-hydraulic
Ukuhlolwa kwe-hydraulic kuzokwenziwa kumapayipi ensimbi ngamunye ngamunye. Ingcindezi yokuhlola ephezulu ingu-20 MPa. Ngaphansi kwengcindezi yokuhlola, isikhathi sokuzinza akufanele sibe ngaphansi kwe-10 s, futhi ukuvuza kwepayipi yensimbi akuvunyelwe.
Ukuhlolwa kokucaba
Ukuhlolwa kokucaba kuzokwenziwa ipayipi lensimbi elinobubanzi obungaphezulu kuka-22 mm
Ukuhlolwa kokuvutha
Ikhwalithi ephezulu yensimbi yesakhiwo sekhabhoni kanye namapayipi ensimbi angagqwali (amelana nokushisa) anobubanzi obungaphandle obungeqile ku-76 mm kanye nogqinsi olungeqile ku-8 mm azobhekana nokuhlolwa okukhulayo. Ukuhlolwa kwe-flaring kuzokwenziwa ekamelweni lokushisa. Izinga lokuvuleka kwedayamitha yangaphandle yesampula ngemva kokuba i-top core taper ingu-60% wokuvutha kuzohlangabezana nezidingo zethebula 7. Akukho mifantu noma imifantu evunyelwe kusampula ngemva kokuvutha. Ngokwezidingo zomuntu odingayo futhi eziphawulwe kwinkontileka, insimbi yesakhiwo se-alloy ingase isetshenziselwe ukwandisa ukuhlolwa.
I teste engonakalisi
Amapayipi ensimbi kufanele atholwe amaphutha e-ultrasonic ngalinye ngalinye ngokuvumelana nezinhlinzeko ze-GB / T 5777-2008. Ngokwezidingo zomfakisicelo, ezinye izivivinyo ezingabhubhisi zingangezwa ngemva kwezingxoxo phakathi komphakeli nomfuneli futhi kukhonjiswe kunkontileka.
Ukuhlolwa kokugqwala kwe-Intergranular
Ukuhlolwa kokugqwala kwe-Intergranular kuzokwenziwa ngepayipi lensimbi elingagqwali (elimelana nokushisa). Indlela yokuhlola izohambisana nezinhlinzeko zendlela yesiShayina E ku-GB / T 4334-2008, futhi ukuthambekela kokugqwala kwe-intergranular akuvunyelwe ngemuva kokuhlolwa.
Ngemuva kwezingxoxo phakathi komphakeli kanye nomfunayo, futhi kuphawulwe kwinkontileka, lowo odingayo angaqoka ezinye izindlela zokuhlola ukugqwala.
