Ipayipi Lensimbi Engenamthungo le-ASTM A53 Isingeniso

Ipayipi lensimbi elingenamthungo le-ASTM A53ihlukaniswe njenge-A53 Type S futhi iyipayipi lensimbi elingenamthungo.

Ihlukaniswe ngamagreyidi amabili, iGrade A neGrade B, futhi ifanele ukusetshenziswa kwemishini kanye nengcindezi, kanye nokusetshenziswa okuvamile kwe-steam, amanzi, igesi, nomoya. Leli payipi lensimbi liyipayipi lensimbi yekhabhoni elifanelekela imisebenzi yokushisela kanye nokwakha okuhlanganisa ukuxhumanisa, ukugoba, kanye nokuxhumanisa i-flange.

Uhla Lwethu Lokunikezwa

Selokhu yasungulwa ngo-2014,Insimbi yeBotopisibe ngumhlinzeki ohamba phambili wamapayipi ensimbi yekhabhoni eNyakatho yeShayina, eyaziwa ngenkonzo enhle kakhulu, imikhiqizo esezingeni eliphezulu, kanye nezixazululo eziphelele.

Le nkampani inikeza amapayipi ahlukahlukene ensimbi yekhabhoni kanye nemikhiqizo ehlobene nayo, kufaka phakathi ipayipi lensimbi elingenamthungo, i-ERW, i-LSAW, kanye ne-SSAW, kanye nohlu oluphelele lwezihlanganisi zamapayipi nama-flange. Imikhiqizo yayo ekhethekile ifaka phakathi ama-alloy ebanga eliphezulu kanye nezinsimbi ezingagqwali ze-austenitic, ezenzelwe ukuhlangabezana nezidingo zamaphrojekthi ahlukahlukene amapayipi.

Inqubo Yokukhiqiza

Amapayipi ensimbi e-ASTM A53 angaba nomthungo noma ahlanganiswe nge-welded.

Indlela yokukhiqiza engenamthungo (Uhlobo S) iwukusebenza okushisayo kwensimbi, futhi uma kudingeka, ukuqeda okubandayo komkhiqizo oshubhu oshisiwe ukuze kufezwe ukuma, ubukhulu, kanye nezakhiwo ezidingekayo.

Ukwakheka Kwamakhemikhali Okungenamthungo kwe-ASTM A53

Ezingeni le-ASTM A53, izidingo zokwakheka kwamakhemikhali zohlobo S kanyeUhlobo Eamapayipi ensimbi ayafana, kuyilapho izidingo zokwakheka kwamakhemikhali zohlobo F zihlukile.

AIzinto ezinhlanuCu,Ni,Cr,Mo, futhiVndawonye akumele kudlule u-1.00%.

Ukuhlolwa Kokugoba

Nge-DN ≤ 50 [NPS ≤ 2], ubude obanele bepayipi kufanele bukwazi ukugoba bube ngama-90° buzungeze i-mandrel esilinda, ububanzi bayo obuphindwe kabili kunobubanzi obuchazwe ngaphandle bepayipi, ngaphandle kokudala imifantu kunoma iyiphi ingxenye.

Okuphindwe kabili okunamandla kakhulu(XXS) ipayipi elingaphezu kwe-DN 32 [NPS 1 1/4] akudingeki ukuthi lihlolwe ukugoba.

Ukuhlolwa Kokuthamba

Amashubhu ensimbi angenamthungo akudingeki ukuthi ahlolwe ukuthi ayasicaba.

Uma kudingeka yinkontileka, ukuhlolwa kungenziwa ngokwenqubo eku-S1.

Ukuhlolwa Kwamanzi

Zonke izinhlobo zamapayipi ensimbi angenamthungo kufanele zigcine inani elithile lomfutho wamanzi ngaphandle kokuvuza okungenani imizuzwana emi-5.

Ingcindezi yokuhlola yamapayipi ensimbi angenasici ingatholakala kuThebula X2.2.

Izingcindezi zokuhlola zamapayipi ensimbi anezintambo nahlanganisiwe zingatholakala kuThebula X2.3.

Ukuhlolwa Kukagesi Okungabhubhisi

Ingasetshenziswa njengenye indlela yokuhlolwa kwe-hydrostatic.

Ubude bonke bepayipi ngalinye elingenamthungo kufanele buhlolwe ngogesi ngendlela engonakalisi ngokuhambisana ne-E213, I-E309nomaE570.

Ukugqoka Okungaphezulu

Izinga le-ASTM A53 licacisa izidingo zesimo sepayipi elimnyama kanye nokufakwa kwe-hot-dip galvanized kwamapayipi ensimbi.

Ipayipi Elimnyama

Ipayipi elimnyama libhekisela esimweni sepayipi lensimbi ngaphandle kokwelashwa kwendawo.

Amapayipi amnyama avame ukusetshenziswa ezindaweni lapho isikhathi sokugcina sifushane khona, indawo ezungezile yomile futhi ingagqwali, futhi intengo ivame ukuba phansi ngoba akukho uqweqwe.

Isimbozo Esishisayo Esicwebezelayo

Amapayipi agqitshwe nge-galvanized, aziwa nangokuthi amapayipi amhlophe, avame ukusetshenziswa ezindaweni ezinomswakama noma ezigqwalisayo.

I-zinc esembozweni se-zinc ingaba yinoma yiliphi izinga le-zinc ku-ASTM B6.

Ipayipi elihlanganisiwe kumele lingabi nezindawo ezingamboziwe, ama-blister, ama-flux deposits, kanye nokungcola okukhulu. Amaqhubu, ama-projection, ama-globules, noma ama-zinc deposits asindayo azophazamisa ukusetshenziswa okuhlosiwe kwezinto ngeke avunyelwe.

Okuqukethwe kwe-zinc okungaphansi kuka-0.55 kg/m² [1.8 oz/ft²].

Ezinye Izimbozo

Ngaphezu kokugqoka ipayipi elimnyama kanye ne-galvanized, izinhlobo ezivamile zokugqoka zifaka phakathiupende, 3LPE, I-FBE, njll. Uhlobo olufanele lokumboza lungakhethwa ngokuya ngezidingo ezithile zendawo yokusebenza.
