I-ASTM A53 yeBanga A ne-B Yepayipi Lensimbi - IBHULOJI

Incazelo Yomkhiqizo

I-ASTM A53 iwukucaciswa okujwayelekile kwepayipi lensimbi ye-carbon ngamapayipi amancane, okuhloswe ngawo ukudlulisa amanzi, igesi, umoya, umusi kanye nokusetshenziswa okuvamile kwemishini nesakhiwo. Ivala ipayipi elingenamthungo, ipayipi elishiselwe i-ERW kanye nepayipi elishiselwe izinqe{2}, ngamaleveli amabili wamandla (iBanga A kanye neBanga B).
I-Octal Pipe ihlinzeka nge-ASTM A53 yeBanga A kanye neBanga B ngokufakwa uthayela ongazikhethela, iziphetho ezihlukahlukene, kanye nezitifiketi ezigcwele zokugaya ukuze kuthunyelwe iphrojekthi.

Izinhlobo Zomkhiqizo

Uhlobo S - Okungenamthungo

Ipayipi elishisayo-eliqediwe noma elibandayo-eliqediwe elingenamthungo. Okuncanyelwayo kumasistimu okucindezela, izinsiza zezitshalo kanye nesevisi yemishini lapho kudingeka khona ukufana ngodonga.

Uhlobo E – ERW (Ugesi-I-Resistance Welded)

Ipayipi elishiselwe ngobude elinokushisa okushiselwe{0}}eliphathwa njengoba kudingwa yisimiso. Inketho-ephumelelayo yezindleko zemigqa ewuketshezi, amasistimu omlilo nezinhlelo zokusebenza zesakhiwo.

Uhlobo F – Isithando somlilo-Izinqe Ezishiselwe

Itholakala ebangeni A kuphela. Isetshenziselwa{1}}isevisi elula lapho ukucaciswa kuvumela le nqubo.

Amabanga

Ibanga A:amandla ajwayelekile esevisi ejwayelekile

Ibanga B:ukuqina okuphezulu namandla okukhiqiza, acaciswe kakhulu ukucindezela nokusetshenziswa kwemishini

Ukwakheka Kwamakhemikhali

Isici	Ibanga A (ubukhulu %)	Ibanga B (ubukhulu %)	Umsebenzi
Ikhabhoni (C)	0.25	0.30	Amandla, alawulelwe ukushisela
I-Manganese (Mn)	0.95	1.20	Ukuqina, ikhwalithi yokushisela
I-Phosphorus (P)	0.05	0.05	Ikhawulela ukuqina
Isibabule (S)	0.045	0.045	Ilawulwe ukuqina/ukusebenziseka
Ithusi (Cu)*	0.40	0.40	Ukumelana nokugqwala okwengeziwe
I-Nickel (Ni)*	0.40	0.40	Ukugcinwa kwamandla
I-Chromium (Cr)*	0.40	0.40	Ukuqina kobuso
I-Molybdenum (Mo)*	0.15	0.15	Ukugcinwa kokuqina
I-Vanadium (V)*	0.08	0.08	Ukuhluzwa okusanhlamvu

Izakhiwo Zemishini

Impahla	Ibanga A	Ibanga B	Amanothi
Amandla aqinile	Kukhulu noma kulingana no-330 MPa (48 ksi)	Kukhulu noma kulingana no-415 MPa (60 ksi)	Amandla epayipi ewonke
Amandla esivuno	Kukhulu noma kulingana no-205 MPa (30 ksi)	Kukhulu noma kulingana no-240 MPa (35 ksi)	Ingcindezi / umthamo wesakhiwo
Ukwelula	Kukhulu noma kulingana no-30%	Kukhulu noma kulingana no-30%	Ifanele ukuthunga, ukugoba, ukwenziwa

IBanga B, elinokuqina okuphezulu kanye namanani esivuno, liyinketho evamile yemigqa yokucindezela, amasistimu omlilo kanye nesevisi yemishini.

Ukukhiqiza Nokulawula Inqubo

I-ASTM A53 ivumela imizila engenamthungo neshiselwe. Amapayipi angenamthungo ayashisa-ayasebenza futhi anosayizi odingekayo ukuze ufike ku-OD nogqinsi oludingekayo. Amapayipi e-ERW kufanele abe nomsindo, ukushisela okuqhubekayo; indawo yokushisela iyashiswa{4}}iyaphathwa uma icacisiwe ukuze i-untempered martensite ingabi khona. Isithando somlilo-ipayipi elishiselwe izinqe lilinganiselwe kuBanga A.

Bonke ubude bepayipi bungaphansi koku:

ukuhlolwa okubukwayo nobukhulu bokuqondile, i-OD, udonga kanye nendawo
ukuhlolwa kwe-hydrostaticnomakugunyazwe ukuhlola{0}okungacekeli phansi
ukugoba/ukuhlolwa kokucaba kwemikhiqizo eshiselwe ukuze kuqinisekiswe ikhwalithi yokushisela

Leli zinga lokulawula lenza i-A53 yamukeleke kuketshezi, igesi kanye nesevisi yesakhiwo ezakhiweni, ezitshalweni nasezinsizeni.

Ubukhulu & Ukubekezelelana

Ipharamitha	Ukucaciswa
Usayizi Wepayipi Lokuqamba	1/8 kokungu-26 kokungu-(DN 6 – DN 650)

Okushisayo-Inketho Ye-Dip Galvanized

Amapayipi e-ASTM A53 angase afakwe ashisayo-ediphu efakwe uthayela ngokucwiliswa. I-Zinc izohlangana ne-ASTM B6, futhi isisindo sokumboza ngeke sibe ngaphansi kwamanani amancane ashiwo ku-ASTM A53. Ukumbozwa kufanele kuqhubeke, kungabi namachashaza angenalutho, amabhamuza kanye nemfucuza enzima.
I-Galvanized A53 inconyelwe imigqa yangaphandle, izinsiza zamanzi nezomoya, ukuvikela umlilo obala, kanye nezindawo zezimboni ezidinga ukumelana nokugqwala okuthuthukisiwe. I-Octal Pipe inganikezela ngamapayipi amnyama nakanozinti ukusuka kububanzi obufanayo bosayizi, nokuqinisekiswa kokumboza.

Izicelo Ezijwayelekile

Amanzi, igesi kanye{0}}nezintambo zomoya ezicindezelwe ezakhiweni, ezitshalweni nasezinhlelweni zikamasipala
{{0}amasevisi aphansi anengcindezi kanye ne-condensate
Ukuvikela-umlilo namapayipi okufafaza (lapho i-ASTM A53 ivunyelwe yizinga lesistimu)
Amalungu esakhiwo kanye nemishini asebenzisa ipayipi njengamakholomu, ama-bracing noma amafreyimu
Isevisi yamapayipi okuvamile kanye ne-casing ye-wiring/drainage lapho kungadingeki i-API 5L

Ukunikezela & Isitifiketi - Ipayipi le-Octal

I-ASTM A53 Uhlobo S / Uhlobo E / Uhlobo F
Amabanga A no-B
Okumnyama, okuvanishiwe noma okushisayo-okucwilisa uthayela
Iziphetho ezingenalutho, eziboshwe, ezinentambo noma ezihlanganisiwe
