Insimbi ye-ASTM A513iyipayipi lensimbi yekhabhoni ne-alloy kanye nethubhu elenziwe ngensimbi egoqekile noma egoqekile ebandayo njengezinto zokusetshenziswa ngenqubo yokumelana nokushisela (i-ERW), esetshenziswa kabanzi kuzo zonke izinhlobo zezakhiwo zemishini.
Uhlobo 1 lungahlukaniswa lube yi-1a kanye ne-1b.
Uhlobo 1a (AWHR): "njengokushiselwe" ngensimbi egoqwe ngokushisa (enesilinganiso sokugaya).
Lolu hlobo lwepayipi lushintshwa ngqo kusuka ensimbini egoqwe ngokushisa nge-iron oxide (isikali sokugaya) esakhiwe ngesikhathi sokugoqwa. Lolu hlobo lwepayipi luvame ukusetshenziswa ezisetshenziswa lapho ubuqotho bomphezulu bungabalulekile ngoba umphezulu uqukethe isikali sokugaya.
Uhlobo 1b (AWPO): "njengokushiselwe" kusuka ensimbini egoqwe ngokushisa efakwe ukhilimu nenamafutha (kususiwe isikali sokugaya).
Lolu hlobo lwepayipi lushiselwe ngensimbi egoqwe ngokushisa efakwe ukhilimu futhi igcotshwe ngamafutha futhi lubonakala ngokususwa kwesikali sokugaya. Ukwelashwa kokhilimu nokhilimu akususi nje kuphela ukungcoliswa kwendawo kodwa futhi kunikeza ukuvikelwa kokugqwala kanye nokugcotshwa ngesikhathi sokucubungula, okwenza leli payipi lifaneleke kakhulu ekusetshenzisweni okudinga indawo ehlanzekile noma izimo zokucubungula eziqinile kancane.
Izinga lokusebenza: ASTM A513
Izinto: Insimbi Egoqwe Ngokushisayo noma Egoqwe Ngokubandayo
Inombolo yohlobo： Uhlobo 1 (1a noma 1b), Uhlobo 2, Uhlobo 3, Uhlobo 4,Uhlobo 5, Uhlobo 6.
Ibanga: MT 1010, MT 1015,1006, 1008, 1009 njll.

I-ASTM A513 Round Tubing Type 1 Amazinga avamile yilawa:
1008,1009,1010,1015,1020,1021,1025,1026,1030,1035,1040,1340,1524,4130,4140.
I-Hot-rolled
Enqubweni yokukhiqiza, insimbi egoqwa ngokushisa iqala ifudunyezwe emazingeni okushisa aphezulu, okuvumela insimbi ukuthi igoqwe isesimweni sepulasitiki, okwenza kube lula ukushintsha ukuma nosayizi wensimbi. Ekupheleni kwenqubo yokugoqwa ngokushisa, izinto ezisetshenziswayo zivame ukukalwa futhi ziguquguquke.
Amapayipi kufanele enziwe yi-okushiselwe ngokumelana nogesi (ERW)inqubo.
Ipayipi le-ERW inqubo yokwakha i-weld ngokuhlanganisa izinto zensimbi zibe yi-cylinder bese usebenzisa ukumelana nokucindezela ubude bayo.
Insimbi kumele ivumelane nezidingo zokwakheka kwamakhemikhali ezichazwe kuThebula 1 noma kuThebula 2.

I-RB ibhekisela ku-Rockwell Hardness B Scale.
Izidingo zobulukhuni ezihambisana namamaki athile zingabonakala kuithebula elingenhla le-RB.
1% wawo wonke amapayipi endaweni ngayinye futhi angabi ngaphansi kwamapayipi ama-5.
Amashubhu ayindilinga namashubhu akha ezinye izimo uma eyindilinga ayasebenza.
Zonke izipayipi zizohlolwa nge-hydrostatic.
Gcina ingcindezi encane yokuhlolwa kwamanzi okungenani imizuzwana emi-5.
Ingcindezi ibalwa kanje:
P=2St/D
P= ingcindezi yokuhlola ye-hydrostatic encane, i-psi noma i-MPa,
S= ukucindezeleka kwefayibha okuvumelekile okungu-14,000 psi noma i-96.5 MPa,
t= ubukhulu bodonga obucacisiwe, ngo. noma mm,
D= ububanzi obungaphandle obucacisiwe, ngaphakathi noma mm.
Inhloso yalolu vivinyo ukwenqaba amapayipi aqukethe amaphutha alimazayo.
Ithubhu ngalinye kufanele lihlolwe ngokuhlolwa kukagesi okungabhubhisi ngokuhambisana ne-Practice E213, Practice E273, Practice E309, noma i-Practice E570.

Maka ulwazi olulandelayo ngendlela efanele ngenduku noma inqwaba ngayinye.
igama lomkhiqizi noma uhlobo, usayizi ocacisiwe, uhlobo, inombolo ye-oda lomthengi, kanye nale nombolo yencazelo.
I-Barcoding iyamukeleka njengendlela yokuhlonza eyengeziwe.
Ipayipi kufanele lingabi namaphutha alimazayo futhi kufanele libe nomklamo ofana nowenziwe ngumuntu.
Izinhlangothi zepayipi kumele zinqunywe kahle futhi zingabi nama-burrs noma imiphetho ebukhali.
I-Chip Egoqiwe (yohlobo 1a): Uhlobo 1a (oluvela ngqo ensimbini egoqiwe eshisayo enama-chip agoqiwe) luvame ukuba nobuso be-chip obugoqiwe. Lesi simo sobuso siyamukeleka kwezinye izinhlelo zokusebenza lapho ikhwalithi ephezulu yobuso ingadingeki khona.
I-Chip Egoqiwe Esusiwe (yohlobo 1b): Uhlobo 1b (olwenziwe ngensimbi egoqiwe eshisayo nefakwe amafutha kanye nama-chip agoqiwe asusiwe) lunikeza indawo ehlanzekile yezicelo ezidinga ukupenda noma ikhwalithi engcono yendawo.
Amapayipi kufanele ambozwe ngefilimu yamafutha ngaphambi kokuthunyelwa ukuze kuvinjelwe ukugqwala.
Uma i-oda lichaza ukuthi amapayipi kufanele athunyelwe ngaphandleuwoyela ovimbela ukugqwala, ifilimu yamafutha akhiqizwayo izohlala phezu kwamanzi.
Kungavimbela ngempumelelo ubuso bepayipi ukuthi bungahlangani nomswakama nomoya-mpilo emoyeni, ngaleyo ndlela kugwenywe ukugqwala nokugqwala.
Kushibhile: Inqubo yokushisela insimbi egoqwe ngokushisa yenza i-ASTM A513 Type 1 ithengeke kakhulu uma kuqhathaniswa nemikhiqizo edonswa ebandayo.
Uhla olubanzi lwezicelo: Uhlobo lwe-ASTM A513 1 lufanelekela izinhlelo zokusebenza ezahlukahlukene, kufaka phakathi izingxenye zesakhiwo, ozimele, amashelufu, nokuningi. Ukuguquguquka kwalo ezindaweni ezahlukene kanye nemisebenzi kwenza kube ukukhetha okuthandwayo kwezimboni ezifana nezimoto, ezokwakha kanye nemishini.
Ukushibilika okuhle kakhulu: Ukwakheka kwamakhemikhali kwe-ASTM A513 Type 1 kuhle kakhulu ekushiseni, futhi kungashiselwa kusetshenziswa izindlela eziningi zokushisisa ezivamile, okwenza kube wusizo kakhulu ezindaweni ezahlukahlukene zokukhiqiza.
Amandla nokuqina okuhle: Nakuba ingaqinile njengezinye izinsimbi ze-alloy noma izinsimbi ezilungisiwe, ihlangabezana nesidingo sokunikeza amandla anele ezinhlotsheni eziningi zesakhiwo nezomshini. Ukucubungula okwengeziwe, njengokwelashwa kokushisa, kungathuthukisa futhi izakhiwo zomshini zepayipi ukuze kuhlangatshezwane nezidingo ezithile.
Ukuqedwa KomphezuluUhlobo 1b lunikeza indawo ehlanzekile, okuwusizo ekusetshenzisweni lapho kudingeka khona ukuqeda okuhle kwendawo futhi lapho kudingeka ukupenda noma ukulungiselela okwengeziwe kwendawo.
Uhlobo lwe-ASTM A513 1 lunikeza ibhalansi enhle yezindleko, ukusebenza, kanye nokuguquguquka, okwenza lufanelekele ukusetshenziswa okuningi kwemishini nezakhiwo lapho kudingeka khona amapayipi angabizi anezakhiwo ezinhle zemishini.
Kusetshenziswa ekwakheni njengezakhiwo ezisekelayo njengemishayo namakholomu.
Kusetshenziswa ekukhiqizweni kwezingxenye zesakhiwo semishini eyahlukahlukene yemishini, njengezinsimbi zokuthwala kanye nemigodi.
Uhlaka kanye nezakhiwo zokusekela emishinini yezolimo.
Kusetshenziswa ekwakheni amashelufu ensimbi kanye nezinhlelo zokugcina izinto ezindaweni zokugcina impahla kanye nezitolo.
Singomunye wabakhiqizi nabahlinzeki bepayipi lensimbi yekhabhoni elihlanganisiwe abahamba phambili kanye namapayipi ensimbi angenamthungo abavela eShayina, sinezinhlobonhlobo zamapayipi ensimbi asezingeni eliphezulu esitokweni, sizibophezele ekukunikezeni uhla oluphelele lwezixazululo zamapayipi ensimbi.
Ukuze uthole imininingwane eyengeziwe yomkhiqizo, sicela ukhululeke ukuxhumana nathi, silangazelela ukukusiza ukuthola izinketho ezinhle kakhulu zamapayipi ensimbi ezifanela izidingo zakho!
