Umbhobho we-API ongenamthungo vs. Welded: Yeyiphi omawuyikhethe?

Kwiiprojekthi zeziseko zophuhliso ezinobungozi obukhulu ezifana namaqonga okumba ioyile elwandle, izityalo zeekhemikhali, okanye imibhobho yegesi enoxinzelelo oluphezulu yesixeko, imibhobho yeyona nto iphambili kwiprojekthi. NgokuphatheleleUmbhobho wentsimbi we-API 5Lumgangatho, ingxoxo idla ngokugxila kwiindlela ezimbini eziphambili:umbhobho wentsimbi ongenamthungokwayeumbhobho wentsimbi odibeneyo(ERW/LSAW).

Ukukhetha umbhobho ongalunganga akuyonto nje yohlahlo-lwabiwo mali, kodwa kukwangumcimbi wokhuseleko kunye nobomi. Apha ngezantsi kukho isikhokelo esibanzi sokukunceda ufumane umbhobho ofanelekileyo kwisicelo sakho esithile.

Ukuqonda Umsantsa Wokuvelisa

Umahluko oyintloko phakathi kwemibhobho yentsimbi engenamthungo kunye nemibhobho yentsimbi edibeneyo isezinkqubo zayo zokwenziwa.

Iipayipi zeNsimbi ezingenamthungo (ii-SMLS)

Imibhobho yentsimbi engenamthungo yenziwa ngokugrumba imingxunya kwibhilethi yentsimbi eqinileyo ejikelezileyo kusetyenziswa inkqubo yokugaya i-mandrel. Ngenxa yokuba akukho welding, umjikelezo wepayipi uyafana ngokupheleleyo.

Iingenelo:Ukumelana noxinzelelo oluphezulu, ukuthembeka okuphezulu, ukufana okuhle kwejometri (ukujikeleza okuphezulu).

Iingxaki: Iindleko eziphezulu zemveliso, ixesha elide lokuhambisa iipayipi ezinkulu.

 

Iipayipi zentsimbi ezidityanisiweyo (I-ERW, i-LSAW, i-SSAW)

Imibhobho yentsimbi edityanisiweyo yenziwe ngeebhilethi zentsimbi, iikhoyili, okanye iipleyiti. Ibhilethi iqengqwa ibe yipayipi ize idityaniswe kusetyenziswa i-high-frequency resistance welding (ERW) okanye i-submerged arc welding (LSAW).

Iingenelo:Ixabiso layo liphezulu, ifumaneka ngobubanzi obukhulu, kwaye ubukhulu bodonga bufana kakhulu (ukunyamezelana).

Iingxaki:Umthungo we-weld ubusoloko uthathwa njenge "ndawo ebuthathaka," nangona uvavanyo lwanamhlanje luye lwanciphisa kakhulu le ndlela yokucinga.

Uxinzelelo kunye nobushushu: Amanqaku aphuhlisayo

Iimeko zokusebenza kufuneka zibe zezona zinto zibalulekileyo ekufuneka uziqwalasele xa usenza izigqibo.

Ukusetyenziswa koxinzelelo oluphezulu kakhulu:Iityhubhu ezingenamthungo ziyindlela eqhelekileyo yokusetyenziswa koxinzelelo oluphezulu kakhulu. Ngenxa yokuba akukho zi-welds ezinde, akukho mngcipheko "wokungaphumeleli kwe-weld."Ukuba isicelo sakho sifuna uxinzelelo olungaphezulu kwe-2,000 PSI, ukuthungwa kwemibhobho engenamthungo kusenokwenzeka ukuba lolona khetho lukhethwayo.

Iindawo ezineasidi/ezirhabaxa:Kwiindawo ezine-asidi (eziqulethe i-hydrogen sulfide), ii-welds zetyhubhu ezidityanisiweyo zisengozini enkulu yokuqhekeka kwe-stress corrosion (SCC). Ngelixa ii-welds zetyhubhu ezisemgangathweni ophezulu zifumana unyango olukhethekileyo lokumelana nokubola,iityhubhu ezingenamthungoinenzuzo yendalo kwi-homogeneity yeekhemikhali kwaye ngoko ke iyamelana ngakumbi.

Ipayipi ye-API 5L Umbhobho oBalulekileyo woThutho lwaMandla

Izinto ezibalulekileyo malunga nobukhulu kunye nobukhulu

Ukhetho lwakho lunokwenziwa ngokusekelwe kuphela kububanzi obufunekayo bangaphandle (OD).

Uhlobo lwePipe Uluhlu lobukhulu obuqhelekileyo Eyona ndlela ilungileyo yokusebenzisa
Akukho mthungo 1/8" ukuya kuma-26" Imigca enoxinzelelo oluphezulu, enobubanzi obuncinci ukuya kobuphakathi.
I-Welded (ERW) 2" ukuya kwi-24" Uxinzelelo oluphantsi ukuya koluphakathi, uthutho olude.
I-Welded (LSAW) 16" ukuya kuma-60"+ Uthumelo olukhulu oluphambili, iipileni zesakhiwo.

 

Ukuba ufunaIi-intshi ezingama-48Umbhobho oyintloko wombhobho wegesi onqumla ilizwe, akunakwenzeka ukuba wenziwe ngolo hlobo. Uza kunyuka uyeI-LSAW (iLongitudinal Submerged Arc Welded) okanye umbhobho we-SSAW (Spiral).

Uhlalutyo lweNdleko-Inzuzo

Ngamaxabiso angoku,umbhobho odibeneyo uxabisa malunga nama-20% ukuya kuma-30% kunetyhubhu yentsimbi engenamthungo enobukhulu obufanayo nomgangatho ofanayo..

Ixesha lokugcina:Ukuba ufuna ukuthutha amanzi, ukuqokelela ioyile negesi ngoxinzelelo oluphantsi, okanye ufuna nje imibhobho yokwakha, umbhobho odibeneyo lolona khetho lungabizi kakhulu.

Ixesha lokutyala imali engaphezulu:Kwiinkqubo zobomi okanye ukufa, kwiipayipi zamandla, okanye kwiindawo ezishushu kwiindawo zokucocisa, iindleko ezongezelelweyo zepayipi engenamthungo zilingana nomshuwalense wokungaphumeleli okukhulu.

Imigangatho yoMgangatho: I-API 5L Factor

Ukunikezelwa kwamanqanaba akukachaphazeleki (nangona amanqanaba ePSL1 kunye nePSL2 ahlukile). Zombini intsimbi engenamthungo neyinyibilikiswayo kufuneka ihlanganeI-API 5L PSL1 PSL2amanqanaba eenkcukacha zemveliso.

I-PSL1: Umgangatho oqhelekileyo wezicelo ngokubanzi.

I-PSL2: Iimfuneko ezingqongqo ngakumbi zokwakheka kweekhemikhali, ukuqina kwe-notch, kunye neempawu zoomatshini. Uninzi lweeprojekthi zaselwandle kunye nezoxinzelelo oluphezulu ziyalela ukusetyenziswa kwentsimbi engenamthungo ye-PSL2.

Isiphelo Sokugqibela: Yeyiphi Ofanele Uyikhethe?

Ukhetho lwePipe yeNtsimbi engenamthungo:Ukuba ukwiindawo ezineegesi ezinoxinzelelo oluphezulu, umphunga oshushu kakhulu, okanye ulwandle olunzulu, ukulungiswa akuyi kuba yinto enokwenzeka xa kukho ukusilela.

Ukhetho lwePipe yeNsimbi eWelded:Ukuba usebenza kwiprojekthi enkulu efuna uxinzelelo oluphakathi, kufuneka imibhobho enobubanzi obungaphezulu kwee-intshi ezingama-24, okanye ube nohlahlo lwabiwo-mali olulinganiselweyo lwenkcitho-mali.

Iingcebiso zoBugcisa:Ngaphambi kokuba ugqibezele uluhlu lwakho lokuthenga, qhagamshelana nonjineli weprojekthi oqeqeshiweyo okanye umthengisi onamava ukuze ahlole "iiparameter zoyilo" lwakho oluthile. Imibhobho efanelekileyo ayifanele ibe namandla aphezulu kuphela kodwa ikwaqinisekise ukhuseleko kunye nokusebenza kakuhle kweendleko.

Faka iimfuno zakho zeprojekthi ukuze ufunde ngakumbi malunga neenkcukacha kunye nezinto ekufuneka uziqwalasele kwiprojekthi yakho.
