Ububanzi be-ASTM A53
Amapayipi ensimbi angenamthungo futhi ashiselwe asuka ku-DN 6 kuya ku-650 mm anogqinsi lwezindonga ngokwe-ASTM A53 Tables X2.2 kanye ne-X2.3, kanye namapayipi ensimbi.
I-ASTM A53 Uhlobo kanye neBanga
Uhlobo Lwepayipi
Uhlobo F:
Ipayipi Elishiselwe Izinqe Zesithando - Ipayipi elishiselwe ngokuqhubekayo.Ikhiqiza ubude obuningi bamapayipi, abese esikwa abe ngobude obubodwa futhi ashiselwe ngomfutho wemishini odalwa amaroli ashisayo.
Qaphela: Uhlobo F alutholakali ngama-flange
Uhlobo E:
ipayipi elishiselwe ukumelana.Ilunga le-butt eliyi-longitudinal elinobude obubodwa, noma ebuningini bobude ukusuka ekesejini elicijile, bese lisikwa libe ubude obubodwa, libe nelunga le-butt eyi-longitudinal, lapho ukuhlangana kukhiqizwa khona ukushisa okutholakala ngenxa yokumelana nomsinga kusekethe lapho ipayipi likhona, nangokusetshenziswa kwengcindezi.
Yazi: Uhlobo E lunikezwe noma lunganwetshwanga noma lubandayo lunwetshwe ngokukhethwa komkhiqizi.
Uhlobo S:
Amapayipi Angenamthungo - Amajoyinti Angenawo Ipayipi Akhiwa ngensimbi esetshenzelwa ngokushisayo, uma kunesidingo, ngokusebenza okubandayo okulandelayo komkhiqizo weshubhu oshisiwe ukuze kukhiqizwe umumo, usayizi, kanye nezakhiwo ezifunekayo.
Iqembu Lebanga
Ibanga A:
Leli banga lesisekelo futhi lifanele ukudluliswa koketshezi olunomfutho ophansi ojwayelekile kanye nezinye izinhlelo zokusebenza zesakhiwo.
IBanga A likhethwa uma amapayipi edinga ukuboshelwa ngokuqinile noma ukugotshwa okubandayo.
Ibanga B:
Leli izinga eliphezulu lamandla okuqinile kanye nebanga lokumelana nengcindezi kuneBanga A futhi livame ukusetshenziswa ezinhlelweni zokucindezela okuphezulu.
I-ASTM A53 Qeda Ukuqeda
I-Flat End: ifomu elijwayelekile lokuphela kwepayipi alicutshungulwa, lisebenza esidingweni sokuqhubeka nokucutshungulwa kwesimo.
Ukuphela Kwentambo: Ukuphela kwepayipi kucutshungulwa ngemicu ukuze kube lula ukuxhumana kwepayipi.
Beveled End: Ukuphela kwepayipi ku-beveled, futhi ikakhulukazi kusetshenziselwa ukuxhumana kwe-welding.
I-ASTM A53 Raw Materials
Insimbi yamapayipi angenamthungo nashiselwe kufanele ikhiqizwe eyodwa noma ngaphezulu yalezi zinqubo:
Isithando somlilo esivulekile, isithando somlilo sikagesi, noma i-Alkaline Oxygen.
Ukwelashwa Kokushisa
Ukushisela okuseBangeni B Uhlobo E noma ipayipi lohlobo F kufanele kufakwe ukushisa ngemva kokushiselwa okungenani kube ngu-1000 F [540°C] ukuze kungabikho i-martensite engafakiwe.
Izidingo Chemical
Izakhiwo Zemishini
I-ASTM A53 Okunye Ukuhlola
Bend Test
I-DN 50 (NPS 2) noma encane: ubude obanele bepayipi buzokwazi ukugotshwa ukubanda nge-90° kuzungeze i-cylindrical mandrel, ububanzi bayo obuphindwe kashumi nambili bucaciswe ububanzi obungaphandle bepayipi, ngaphandle kokwenza imifantu kunoma iyiphi ingxenye futhi ngaphandle kokuvuleka. i-weld.
Vala ukugoqa: ipayipi lizoma ligotshwe libanda ngo-180°ezungeze i-mandrel eyi-cylindrical, ububanzi bayo obuphindwe kasishiyagalombili ubukhulu obubekwe ngaphandle kwepayipi, ngaphandle kokwehluleka.
Ipayipi eliphindwe kabili elinamandla ngaphezu kwe-DN 32 (NPS 11/4):akudingekile ukuthi ihlolwe ngokugoba.
Ukuhlola Ukucaba
Ipayipi elishiselwe ngaphezulu kwe-DN 50 mm ngesisindo esiqinile noma elilula: lizoba yisivivinyo sokucaba.
Ipayipi Elingenamthungo: Akukho ukuhlolwa.
Ukuhlolwa kwe-Hydrostatic
Ipayipi Eliphethe I-Plain-End: Ingcindezi esebenzayo ngokweThebula X2.2.
Ipayipi Elicutshiwe nelihlanganisiwe: Ingcindezi esebenzayo ngokweThebula X2.3.
Ukuhlola Ugesi Okungabhubhisi
Uma ukuhlolwa kukagesi okungacekeli phansi kwenziwe, ubude buzolebula ngezinhlamvu ezithi "NDE".
Kufakwe amagalani
Ipayipi elinothayela le-ASTM A53 kufanele lifakwe uthayela ngaphakathi nangaphandle ngenqubo yediphu elishisayo.
I-zinc esetshenziselwa ukumboza izoba yinoma yiliphi ibanga le-zinc elihambisana ne-Specification B6.Ipayipi elinothayela ngeke libe nezindawo ezingamboziwe, amabhamuza, amadiphozithi agelezayo, kanye nokufaka i-gross dross.Izigaxa, ama-projections, ama-globules, noma amadiphozithi esindayo e-zinc azophazamisa ukusetshenziswa okuhlosiwe kwento ngeke kuvunyelwe.
Ingaphezulu lepayipi lensimbi kufanele libe ne-zinc enamathelayo engekho ngaphansi kuka-0.40 kg/m² ngokubala isisindo kanye nendawo ye-galvanized coating.

Ishadi Lesisindo Sombhobho kanye neSheduli 40 kanye neSheduli 80
Uma ufuna ukwazi okwengeziweIthebula lesisindo sepayipi lensimbi le-ASTM A53, ungachofoza ukuze uthole ulwazi olwengeziwe.
Ukumaka umkhiqizo
→ Igama lomkhiqizi noma ilogo
→ Inombolo yokucaciswa
→ Usayizi (i-NPS nesigaba sesisindo, inombolo yepulani, noma ukujiya kodonga olushiwo; noma kucaciswe ububanzi obungaphandle nokuqina kodonga olucacisiwe)
→ Ibanga (A noma B)
→ Uhlobo lwepayipi (F, E noma S)
→ Emapayipini angenamthungo kukhona futhi izinto ezimbili zokuhlola zikagesi osebenzisa amanzi kanye nongonakalisi, uma wenza ukuthi yiziphi izinto zokuhlola, yikuphi ukuhlolwa okuzomakwa (ingcindezi yokuhlolwa kokulebula nge-hydraulic, ilebula kagesi engabhubhisi i-DNE).
Izinto zikagesi
Ukuthuthwa kwamanzi anengcindezi ephansi: okuhlanganisa amanzi, igesi, nomoya, njll.
Ukusetshenziswa kwesakhiwo: njengezisekelo zesakhiwo, imishayo yamabhuloho, njll.
Amasistimu omusi namanzi ashisayo: amapayipi okushisa kanye nemigqa yesitimu yezimboni.
Ukwakha nokwakha: izinhlelo zamapayipi ezakhiwo ezisekelayo, izikafula zokwakha, ukuthutha nokuhlela izintambo nezintambo.
Isitifiketi
Nikeza NgeSitifiketi Sokuthobela (MTC) kanye nombiko wokuhlola othi impahla yenziwe, yathathwa isampula, yahlolwa, futhi yahlolwa ngokuvumelana ne-ASTM A53 futhi kwatholakala ukuthi iyahambisana.
