Incazelo yomkhiqizo

Ibhonethi yevalvu yensimbi yensimbi esebenza kanzima eyenziwe yaba yi-ASTM A105 / ASTM A350 LF2. Idizayinelwe izinhlelo zokusebenza zephayiphi ze-Class 300 ne-Class 600 ezinengcindezi ephezulu. Idizayini yebhonethi eboshiwe enezindawo zokuvala ezinomshini ezinembayo. Kwamukelwe ukukhwabanisa ngokwezifiso.

Incazelo Egcwele Yomkhiqizo: Ibhonethi ye-valve yesango iyingxenye ebalulekile yokugcina ingcindezi okufanele imelane nokucindezela komugqa ogcwele kanye nokucindezeleka okushisayo okujikelezayo. Amabhonethi ethu ensimbi eyenziwe nge-carbon steel akhiqizwa kusetshenziswa ubuchwepheshe bokubumba obuvaliwe ukuze kuzuzwe ukugeleza kokusanhlamvu okuphakeme, okuqeda ingozi ye-porosity etholakala kwezinye izindlela ezisekelwe ekulingeni.

Ibhonethi ngayinye yenziwa ngamabhilidi e-ASTM A105 noma e-ASTM A350 LF2 (inkonzo yezinga eliphansi), ajwayelekile futhi aqinisiwe ngokwezidingo ze-ASTM A788. Ukucutshungulwa kwe-CNC kuqinisekisa ukunemba kobuso be-flange (≤ 0.05 mm), i-bore concentricity, kanye nokunemba kwentambo yendawo yokupakisha isiqu.

Idizayini yebhonethi eboshiwe ithatha ama-graphite gaskets ajwayelekile anenxeba futhi yamukela izinto zokupakisha ezijwayelekile (PTFE, graphite, asbestos-free). Itholakala kuma-valve esango angu-2" ukuya kwangu-24" anezinketho ezijwayelekile noma ezinwetshiwe zentamo yebhonethi.

Izici Eziyinhloko:

Inqubo yokuqamba: I-closed-die forging hot - isakhiwo sokusanhlamvu esiphezulu, impilo yokukhathala okuphezulu
Impahla: ASTM A105 (okujwayelekile) / ASTM A350 LF2 (isevisi yezinga lokushisa eliphansi −46°C)
Ukwelashwa kokushisa: Okujwayelekile + okulinganiselwe (N+T) ngokwezidingo ze-ASTM A105
Ukucupha: I-CNC egcwele - ubuso be-flange, i-bore, intambo, igumbi lokupakisha
I-NDE: UT (ukuhlolwa kwe-ultrasonic) kuwo wonke ama-forgings abalulekile; MT (izinhlayiya kazibuthe) uma ucela
Ukulawulwa kokuqina okuthobelana kwe-NACE MR0175 kuyatholakala ngesevisi emuncu
Izinga le-Dimensional: ASME B16.34, API 600

Izimboni zohlelo lokusebenza:

Uwoyela negesi enhla nomfula / phakathi nomfula / ezansi nomfula
Izitshalo zokucwenga kanye ne-petrochemical
Ukukhiqiza amandla (ama-valve omusi)
I-LNG kanye nepayipi le-cryogenic (A350 LF2)
Imishini yasolwandle kanye ne-offshore

Kungani Sikhethe: Umshini wethu wokukhanga ovaliwe (ofika kumathani angu-2,500) kanye nesitolo somshini we-CNC esihlanganisiwe sisivumela ukuthi silethe amabhonethi e-valve aseqedwe ngokuphelele, alungele ukuhlanganisa emthonjeni owodwa. Wonke ama-forging abalulekile ahambisana nemibiko yokuhlolwa kwezinto (MTR/CMTR) kanye nemibiko yokuhlola enobukhulu. Samukela ukuhlolwa okuvela eceleni futhi singaxhumanisa ukuhlolwa kofakazi efekthri yethu.
