Isingeniso Se-Concentric Reducer

Isinciphisi esiphakathi nendawo emugqeni oqondile sibizwai-concentric reducer.Inqubo yokubumba evame ukusetshenziswa ukunciphisa, ukwandisa noma ukunciphisa kanye nokwandisa, futhi ukugxiviza kungasetshenziselwa ukunciphisa amapayipi okucaciswa okuthile.

Ukucaciswa komkhiqizo:

3/4 “X1/2″ — 48 “X 40″ [DN 20 X 15 --- 1200 X 1000]

Ubukhulu bodonga:

Sch 5s -160

Amazinga aphezulu:

I-GB/T12459-2005, ANSI, JIS, BS, DIN, UNI, njll.

Izinto zomkhiqizo:

Carbon steel, Stainless steel

Indlela yokupakisha:

Amakesi amapulangwe amahhala kanye namaphalethi angafakwa ngokukhethekile ngokwezidingo zamakhasimende.

Isicelo somkhiqizo:

Ubunjiniyela bepayipi legesi yegesi, ubunjiniyela bepayipi legesi yemvelo, imboni yamakhemikhali, indawo yokuphehla amandla, indawo yemikhumbi, ikhemisi, ubisi, ubhiya, isiphuzo, ukongiwa kwamanzi, njll.

Qaphela:

Insimbi ye-Carbon: 10 #, 20 #, A3, Q235A, 20G, 16Mn, ASTM A234, ASTM A105, njll.
Insimbi engagqwali: ASTMA403, 1Cr18Ni9Ti, 0Cr18Ni9, 00Cr19Ni10, 00Cr17Ni14Mo2, 304, 304L, 316, 316L, njll.

Isistimu ejwayelekile:

Ikakhulukazi kunezinhlelo ezimbili zamazinga e-pipe flange emhlabeni, okuyisistimu ye-pipe flange yaseYurophu emelwe yi-DIN yaseJalimane (kuhlanganise ne-Soviet Union yangaphambili) kanye nesistimu ye-flange yamapayipi aseMelika emelwe i-American ANSI pipe flange.Ngaphezu kwalokho, kukhona ama-flange epayipi e-JIS e-Japan, kodwa ngokuvamile asetshenziselwa izinsiza ezitshalweni ze-petrochemical, futhi anomthelela omncane wamazwe ngamazwe.Okulandelayo isingeniso esifushane sama-pipe flange emazweni ahlukahlukene:
1. Ama-flange amapayipi esistimu yaseYurophu amelwe iJalimane kanye nezwe elaliyiSoviet Union
2. Izinga lepayipi lepayipi lesistimu yaseMelika, elimelwe i-ANSI B16.5 ne-ANSI B 16.47
3. Izindinganiso ze-pipe flange zaseBrithani ne-French, izindinganiso ezimbili ze-casing flange zezwe ngalinye.
Ukufingqa, izindinganiso ze-flange zamapayipi ngamazwe zingafingqwa njengezinhlelo ezimbili ze-flange zamapayipi ezihlukene nezingaguquguquki: uhlelo lwe-European pipe flange olumelwe yiJalimane;Enye i-American pipe flange system emelwe yi-United States.

Ukwahlukanisa

1. Ukuhlelwa ngokomsebenzi:
Insimbi ye-Carbon: ASTM/ASME A234 WPB, WPC
Insimbi engagqwali: ASTM/ASME A403 WP 304-304L-304H-304LN-304N
I-ASTM/ASME A403 WP 316-316L-316H-316LN-316N-316Ti
I-ASTM/ASME A403 WP 321-321H ASTM/ASME A403 WP 347-347H
2. Ngokwendlela yokukhiqiza, ingahlukaniswa ngokucindezela, ukucindezela, ukufosha, ukuphonsa, njll.
3. Izindinganiso zokukhiqiza zingahlukaniswa zibe izindinganiso zikazwelonke, izindinganiso zikagesi, izindinganiso zomkhumbi, izindinganiso zamakhemikhali, izindinganiso zamanzi, izindinganiso zaseMelika, izindinganiso zaseJalimane, izindinganiso zaseJapane, izindinganiso zaseRussia, njll.

Izici zokusabalalisa

(1) Isikhathi sokugoba esibangelwa umehluko wengcindezi yendawo phakathi kweziphetho ezinkulu nezincane ze-concentricisinciphisingaphansi kwesenzo sokucindezela kwangaphakathi kubangela isenzakalo sokuthi isiphetho esikhulu sivula ngokuqhathaniswa futhi isiphetho esincane sinciphisa ngokulinganayo;

(2) Ngaphansi kwesenzo sokucindezela kwangaphakathi, ingcindezi ejikelezayo endaweni engaphakathi yesiphetho esikhulu sohlangothi oluyi-eccentric kanye nendawo yangaphandle ephakathi nendawo ye-eccentric sidei-eccentric reducerinkulu kunawo wonke.
