I-SS Butt Welded Fittings iyavutha

Incazelo ye-Butt Welded Fittings

Izici /Izici

• Izinto ezifakwa e-Buttweld izifakelo zamapayipi ezisetshenziselwa ukushintsha indlela yepayipi (izindololwane), ukunciphisa/ukwandisa usayizi wobhobho wamapayipi (izinciphisi), igatsha (amazinyo, isiphambano) noma ukuvala ipayipi (i-butt weld cap)
• Ukufakwa kwe-Buttweld kutholakala ngezimo eziningi (izindololwane, ama tee, izinciphisi, iziphambano, amakepisi, ama-stub end), amamakinari abalulekile (ikhabhoni, ikhabhoni enesivuno esikhulu, i-low-alloy, i-stainless, i-duplex, nama-nickel alloys),
nobukhulu (amayintshi angu-2 ukuya kwangu-24 ekusebenzeni okungenazihibe, futhi ashiselwe osayizi bamapayipi amakhulu).
• Ukucaciswa okubalulekile kokufakwa kwe-buttweld i-ASME B16.9 (i-carbon ne-alloy fittings) kanye ne-MSS SP 43 (ehlanganisa i-ASME B16.9 yensimbi engagqwali, i-duplex, ne-nickel alloy BW fittings).
• Njengoba nje ipayipi lithengiswa kusukela kuSheduli 10 kuya kuSheduli 160, izixhumo zamapayipi okushisela ezinqeni zidayiswa ngendlela efanayo.
Ukufakwa kwe-welded butt weld weld kuvame kakhulu ensimbi engagqwali ngenxa yenzuzo yezindleko. I-Sch 10S, SCH40SUkufakwa kwe-SSnazo zivame kakhulu ekufakweni kwensimbi yensimbi engenasici.
Izinto ezijwayelekile zokufakwa kwe-butt weld yi-A234 WPB (A & C iyatholakala), i-High Yield Carbon Steel, Stainless Steel 304 kanye ne-316 kanye nama-Nickel Alloys.
• Amapayipi ashiselwe ngensimbi ye-carbon nensimbi engagqwali yizingxenye ezihlanganisayo ezenza kube nokwenzeka ukuhlangana kwamavalvu;
amapayipi nezinto zokusebenza ohlelweni lwamapayipi. Ukufakwa okushiselwe kuncoma amapayipi amapayipi kunoma iyiphi isistimu yamapayipi futhi kuvumela:
1.Shintsha isiqondiso sokugeleza ohlelweni lwamapayipi
2.Xhuma noma amapayipi ahlangene kanye nemishini
3. Nikeza amagatsha, ukufinyelela kanye nokusuka kwezinto ezisizayo

Imibuzo nezimpendulo (i-Q&A)

Q:Ikhasimende licele ukufakwa kwe-butt weld ku-A105:
A: Izinto ezisetshenziswa kakhulu ze-carbon steel buttweld fitting yi-A234WPB. Ilingana nama-A105 flanges, nokho ayikho into efana ne-A105 noma i-A106 butt weld fitting.
I-A106 Gr.B eyebanga lamapayipi. Ukufakwa kwe-A234WPB kwenziwa ngamapayipi we-A106GR.B. I-A105 iwumsebenzi osuka kubha eyakhiwe ukuze ibe i-High pressure Fittings noma iFlange
Q: Ikhasimende licela ukufakwa kwe-butt weld "Okujwayelekile":
A: Lona futhi umbono oyiphutha njengoba ama-flange atholakala ku-A105 naku-A105 N, lapho u-N emele ukujwayelekile.
Kodwa-ke, ayikho into efana ne-A234WPBN. Abakhiqizi balungisa ukufakwa kwabo kwe-butt weld kwakubhekwa njengenqubo evamile yokwelapha ukushisa yenziwa, Ikakhulukazi ezindololwaneni kanye namaTees.
Ikhasimende elidinga ukushiselwa kwezinqenqema “okujwayelekile” kufanele licele ukufakwa kwe-WPL6 okunesivuno esikhulu futhi esijwayelekile njengenqubo evamile.
Q: Ikhasimende likhohlwa ukusho uhlelo lwamapayipi:
A: Okufakwayo kwe-Buttweld kuthengiswa ngokosayizi wepayipi ngalinye kodwa ishejuli yepayipi kufanele icaciswe ukuze ifane ne-ID yokufaka ne-ID yepayipi. Uma ingekho ishejuli eshiwo, sizothatha ukuthi udonga olujwayelekile luceliwe.

Q; Ikhasimende likhohlwa ukukhuluma ngokufaka izinqe ezishiselwe noma ezingenamthungo:
Ukufakwa kwe-Butt weld kuyatholakala kukho kokubili okushiselwe nokucushwa okungenamthungo. I-butt weld carbon steel engenamthungo noma okokufaka kwensimbi engagqwali kwenziwa ngepayipi elingenamthungo futhi ngokuvamile kubiza kakhulu.
Ukufakwa kwamapayipi angenamthungo AKUVAMILE ngosayizi abakhulu kuno-12”. Ukufakwa kwamapayipi ashiselwe kwenziwa nge-ERW welded carbon steel noma ipayipi lensimbi engagqwali. Atholakala ngosayizi ½” kuya ku-72” futhi athengeka kakhulu kunawoukufakwa komthungo.
Q: Kusho ukuthini i-Short Radius (SR) noma i-Long Radius (LR)?
A: Ngokuvamile uzozwa indololwane ethi SR45 noma indololwane ye-LR45. I-45 noma 90 ibhekisela ku-engeli yokugoba ukuze kufakwe i-buttweld ukushintsha isiqondiso sokugeleza.
Indololwane ye-radius ende (indololwane ye-LR 90 noma indololwane ye-LR 45) izoba nokugoba kwepayipi okuzoba izikhathi ezingu-1.5 ubukhulu bepayipi. Ngakho, i-6 intshi LR 90 ine-radius egobayo engusayizi wepayipi ongu-1.5 x ojwayelekile.
Indololwane yerediyasi emfushane (SR45 noma SR90) inokugoba kwepayipi elilingana nosayizi wokulinganisa, ngakho-ke u-6” SR 45 unendawo egobayo engusayizi wepayipi ongu-6”.

Q: Liyini ipayipi lendololwane le-3R noma le-3D elifakwayo?
A: Okokuqala, amagama 3R noma 3D asetshenziswa ngendlela efanayo. Indololwane ye-3R butt weld ine-radius egobayo ephindwe izikhathi ezi-3 kunosayizi wepayipi lokuzisholo. Indololwane engu-3R ilingana ne-3D Elbows
