insimbi engagqwali eyakhiwe ithanga elihlangene okuxekethile ikhola ye-flange sch stub end flange

I-lap-joint flange idinga izingxenye ezimbili zamapayipi ohlangothini ngalunye loxhumano oluvulekile, i-stub end kanye ne-backing flange evulekile.I-flange engemuva evulekile ilingana ngaphezu kobubanzi obungaphandle bomkhawulo we-stub, oshiselwe ngezinqe epayipini.I-backing flange ayihlanganisiwe kumbhobho, futhi ingashintshwa, okuwusizo ikakhulukazi uma kudingekile ukuqondisa ama-flanges ngesikhathi sokumiswa.

Futhi, njengoba i-backing flange ingahlangani noketshezi lwenqubo, ingenziwa ngezinto ezikwazi ukumelana nokugqwala.Isibonelo, uma inqubo igqwala futhi idinga ukuthi ipayipi libe ngensimbi engagqwali, njengaku-ASTM A312 TP316L, khona-ke isiphetho se-stub kufanele futhi senziwe nge-SS 316L;Nokho, i-backing flange ingenziwa nge-ASTM A105 eshibhile.

Le ndlela yokuhlanganisa ayiqinile njenge-weld neck flange kodwa iphakeme kune-screwed, i-socket weld, kanye ne-slip on uxhumano;nokho, kubiza kakhulu ukwenza, ngoba kudinga i-butt weld yokungena ngokugcwele futhi kudinga izingxenye ezimbili.

I-Stub End izosetshenziswa njalo nge-Lap Joint flange, njenge-flange esekelayo.

Lokhu kuxhunywa kwe-flange kusetshenziswa, kuzinhlelo zokusebenza ezinengcindezi ephansi futhi ezingabalulekile, futhi kuyindlela eshibhile yokufaka i-flanging.
Kuhlelo lwepayipi yensimbi engagqwali, isibonelo, i-carbon steel flange ingasetshenziswa, ngoba ayihlangene nomkhiqizo wepayipi.

I-Stub Ends iyatholakala cishe kuwo wonke ama-diameter amapayipi.Ubukhulu nokubekezelela kobukhulu kuchazwa kuzinga le-ASME B.16.9.I-Stub Ends (izifakelo) ezimelana nokugqwala okuqinile zichazwa ku-MSS SP43.

• Inkululeko yokuzulazula eduze kwepayipi isiza ukwakheka kwezimbobo zebhawudi ze-flange eziphikisanayo.
• Ukuntula ukuthintana noketshezi olusepayipini ngokuvamile kuvumela ukusetshenziswa kwama-flange ensimbi e-carbon ashibhile anepayipi elimelana nokugqwala.
• Ezinhlelweni eziguguleka noma ezigqwalile ngokushesha, ama-flange angase ahlengwe ukuze aphinde asetshenziswe.

Imininingwane yemikhiqizo iyakhombisa

1. Ubuso
ubuso obuyisicaba, Irediyasi ibaluleke kakhulu

2. Ngehabhu noma ngaphandle kwehabhu

3.Ukuqedwa kobuso
Ukuqeda ebusweni be-flange kukalwa njenge-Arithmetical Average Roughness Height(AARH).Isiphetho sinqunywa yizinga elisetshenzisiwe.Isibonelo, i-ANSI B16.5 icacisa ukuqedwa kobuso ngaphakathi kobubanzi 125AARH-500AARH(3.2Ra ukuya ku-12.5Ra).Okunye ukuqedwa kuyatholakala ngesicelo, isibonelo 1.6 Ra max,1.6/3.2 Ra, 3.2/6.3Ra noma 6.3/12.5Ra.Ububanzi 3.2/6.3Ra buvame kakhulu.

Ukumaka nokupakisha

• Ungqimba ngalunye sebenzisa ifilimu yepulasitiki ukuvikela indawo engaphezulu

• Ngokuba zonke insimbi engagqwali zigcwele plywood case.Ukuze usayizi omkhulu we-carbon flange upakishwe nge-plywood pallet.Noma kungenziwa ngezifiso ukupakisha.

• Uphawu lokuthumela lungenza ngesicelo

• Izimpawu emikhiqizweni zingaqoshwa noma ziphrintwe.I-OEM yamukelwe.

Ukuhlola

• Ukuhlolwa kwe-UT

• Ukuhlolwa kwe-PT

• Ukuhlolwa kwe-MT

• Ukuhlolwa kobukhulu

Ngaphambi kokulethwa, ithimba lethu le-QC lizohlela ukuhlolwa kwe-NDT nokuhlolwa kobukhulu. Futhi yamukela i-TPI(ukuhlolwa komuntu wesithathu).
