Ukuqonda i-ASTM A139: I-BackBone ye-Wih Pipe kunye neZicelo ze-Pemil Ded

Kwihlabathi lokufakelwa kwemizi mveliso, iikhowudi nemigangatho elawula izixhobo ezisetyenzisiweyo zibalulekile ekuqinisekiseni ukhuseleko, ukuqina kunye nokusebenza. Enye yale migangathoI-ASTM A139, edlala indima ebalulekileyo kwimveliso kunye nokusetyenziswa kwe-sawh (i-spiral arc yedled) yemibhobho ye-spilds kunye nemibhobho ye-spild. Kwezi bhlog, siza kuthetha ngokubaluleka kwe-ASTM A139, iimpawu zobhobho yombhobho we-wawh, kunye neengenelo zokuntywila okuthengisiweyo kumashishini ahlukeneyo.

Yintoni i-ASTM A139?

I-ASTM A139 yinkcazo ephuhliswe nguMbutho waseMelika ukuba uvavanywe kunye nezixhobo (i-ASTM) ezichaza iimfuno ze-eledrofusion (i-ARC) yentsimbi ye-Wellded. Lo mgangatho usebenza ikakhulu kwimibhobho esetyenziselwa ukuthutha ulwelo kunye neegesi. Inkcazo igubungela uluhlu olubanzi lwamabakala ensimbi kwaye iqinisekise ukuba imibhobho ivelise ihlangane iipropathi ezithile zoomatshini kunye neengoma zekhemikhali.

Umgangatho we-ASTM A139 ubaluleke kakhulu kubavelisi kunye neenjineli kuba zibonelela ngesikhokelo kwinkqubo yemveliso, kubandakanya neendlela ze-welding kunye namanyathelo olawulo lomgangatho ekufuneka ethathwe. Ngokulandela le migangatho, abavelisi banokuqinisekisa ukuba iimveliso zabo zinokuthenjwa kwaye zilungele iintlobo ezahlukeneyo, ukusuka kwioyile kunye negesi yokuthuthwa kweoyile kunye negesi yokwakha ukusetyenziswa kwesakhiwo.

Indima ye-Sawh Pipeliline

I-Wayh Pipe okanye i-Spiral Arc Welf Poipe Deper luhlobo lombhobho we-welding owenziwe ngamaqhekeza we-pilling the the claes kwi-spind striprical imilo yentsimbi. Le ndlela yemveliso ivumela ukudalwa kwemibhobho emikhulu yedayamere enamandla kwaye iphosakele. Itekhnoloji ye-wlid ye-spilting esetyenziswe ngaphakathiImibhobho ye-Wawh inika izibonelelo ezininzi, kubandakanya:

1. Ukusebenza kweendleko:Inkqubo yemveliso yemibhobho yeWesh ihlala inoqoqosho ngakumbi kunendlela zemveli, esenza ukuba ibe lukhenketho lweeprojekthi ezinkulu.

I-2. Ukungahambi kakuhle:Umbhobho we-Wheh unokwenziwa kubungakanani beentlobo ngeentlobo kunye nobubanzi, owenza ilungele uluhlu olubanzi lwezicelo, kubandakanya nokuhambisa amanzi, iinkqubo zamanzi amdaka, kunye nezinto zokuhombisa.

3. Amandla aphuculweyo:Ukwakhiwa kwe-Weldiral Weldied kubonelela ngamandla kunye nokuxhathisa kuxinzelelo lwangaphandle, ukwenza i-sayh iphele imeko ephezulu yoxinzelelo.

Izinto eziluncedo kumbhobho we-wlil welding

I-Spiral Deliped Pipe ngolunye uhlobo lombhobho we-welding oveliswa kusetyenziswa itekhnoloji ye-spilling ye-spilling. Indlela ibandakanya ukusonga intsimbi ijikeleze i-mandrel kwaye iyinyanzela ngokuqhubekayo spiral.I-wheliling pile inika izibonelelo ezininzi, kubandakanya:

I-1. Iimpawu eziphuculweyo:Umphezulu wangaphakathi wombhobho we-welding we-welding unciphisa isiphithiphithi kwaye uphucule ukuhamba kuka-Faid, owenza ilungele ukusetyenziswa kweoyile kunye negesi.

2. Ubunzima obuncitshisiweyo:Uyilo lweSpiral luvumela iindonga ezinqwenelekayo ngaphandle kokulalanisa, zenza lula umbhobho kwaye kube lula ukuphatha kunye nokuhambisa.

3. Ubude obuqinisekileyo:Umphunga we-Welding welding unokuveliswa ubude obude, ukunciphisa inani lamalungu afunekayo kumbhobho kwaye unciphise ukubakho kokuvuza.

Ukuququmbela

Kwisishwankathelo, i-ASTM A139 nguMgangatho ophambili wokuveliswa kombhobho we-WANH kunye nombhobho we-Wiped Weld, ukuqinisekisa ukuba ezi zinto zibalulekileyo zihlangabezana nemigangatho efanelekileyo yokhuseleko kunye nemigangatho yokusebenza. Ipropathi eyahlukileyo ye-sawh kunye nombhobho we-Welfled Welding wenza ukuba abe nexabiso kumashishini asusela ekwakheni amandla kumandla. Njengoko itekhnoloji iyaqhubeka ukuqhubela phambili, ukubaluleka kokunamathela kwimigangatho emiselweyo njenge-ASTM A139 kuya kukhula kuphela ukuqinisekisa ukuba iziseko zophuhliso esikwalelayo zihlala zikhuselekile kwaye zisebenza ngokufanelekileyo. Nokuba uyinjineli, ikhontraktha, okanye umphathi weprojekthi, ukuqonda le migangatho kunye nezibonelelo zezi ntlobo zepayipi kubalulekile ekwenzeni izigqibo ezinolwazi kwiiprojekthi zakho.
