ERW carbon steel umbhobhovs umbhobho ojikelezayo:

Okokuqala, umahluko phakathi kwenkqubo yokuvelisa
I-ERW carbon steel pipe yi-coil eshushu ephothiweyo ngokuqulunqa umqulu oqhubekayo, ukusetyenziswa kwempembelelo yesikhumba yangoku ye-high-frequency yangoku kunye nemiphumo esondeleyo, ukwenzela ukuba umda we-coil fusion ubushushu, uxinzelelo kwi-coil roller phantsi koxinzelelo lwe-welding ukuphumeza imveliso.Ke ngoko, i-erw carbon steel umbhobho woxinzelelo olushiyekileyo luncinci, ngonyango lobushushu be-weld, ubungakanani, ukulungiswa, uxinzelelo lwamanzi kunye nezinye iinkqubo, uxinzelelo olushiyekileyo lokukhululwa ngakumbi kunye nokunciphisa.Ukuziqhelanisa kuye kwabonisa ukuba i-erw carbon steel pipe kwindawo yokugcina kunye nokusetyenziswa koxinzelelo oluseleyo kwipayipi yensimbi ayichaphazeli.Ngaphandle naluphi na ucingo lwe-welding, i-weld kwiipropati ezibonakalayo kunye nokwakheka kweekhemikhali kunye nepleyiti efanayo.Umgangatho we-erw carbon steel pipe ixhomekeke kumgangatho wephepha.

Umbhobho wentsimbi ovunguzayo ngokusebenzisa iyunithi ukuwelda intambo ejikelezayo kunye, ipleyiti yentsimbi ngokujikeleza okujikelezayo, ukuze uxinzelelo lwejiyometri luntsonkothe ​​ngakumbi, kwaye abanye bade bafikelela kumda wesivuno sepleyiti yentsimbi, ityhubhu ejikelezayo emva kokusekwa kwe Uxinzelelo olukhulu olushiyekileyo, uxinzelelo olushiyekileyo luxinzelelo lokuzibamba.Kwaye umbhobho yentsimbi ngoxinzelelo lwangaphakathi, udonga kwakhona ukuvelisa ring ukucinezeleka tensile, ezimbini superimposed, ukuze ukukwazi ukuba buthathaka umbhobho yentsimbi.Ukusetyenziswa kwenkqubo kungakhuselekanga ngakumbi.Ipleyiti yentsimbi idityaniswe kunye ngocingo olunemichiza, kwaye amaqamza kunye nokuqhekeka kwe-weld bead kunokwenzeka ukuba kwenzeke ngexesha lenkqubo ye-welding.Ukuze i-weld kunye nesiseko sesinyithi kwiipropati ezibonakalayo kunye nokwakheka kweekhemikhali zihluke ngokucacileyo.Kulula ukuvelisa uxinzelelo olukhulu loxinzelelo ngokudibeneyo kunye nesiseko sesinyithi.Kwinkqubo ye-welding, umphumo wokushisa mkhulu, kwaye ubunzima buphezulu.

Okwesibini, umahluko phakathi kwemathiriyeli ekrwada
I-ERW carbon steel pipe esetyenziswe kwizinto eziluhlaza ziveliswa yi-coil eqhelekileyo eshushu, ukubunjwa kweekhemikhali kunye neempawu ezibonakalayo zizinzile.

Uninzi lwesityalo sombhobho we-spiral esetyenziselwa i-low-grade hot-rolled strip, ukwakheka kweekhemikhali kunye neempawu ezibonakalayo kunye nokungazinzi, iziphene zangaphakathi kunye nokungcola ngakumbi.Kuphela kwi-oyile kunye ne-petrochemical system ngaphakathi kwabenzi bombhobho omkhulu ojikelezayo usebenzisa i-coil eshushu eshushu rhoqo ukwenza umbhobho wensimbi ukuze kuqinisekiswe umgangatho kunye nokhuseleko.

Okwesithathu, iindleko zokuthenga kunye nobunzima bokuthenga
I-oyile kunye nenkqubo yepetrochemical yokuveliswa kombhobho omkhulu wentsimbi yombhobho wentsimbi ejikelezayo, iingenelo zayo zigxininiswe kwimveliso yombhobho wentsimbi enobubanzi obukhulu, iindleko zokuvelisa ziphantsi.Nangona kunjalo, kwi-diameter encinci kunye nephakathi (Φ114mm ~ Φ355.6mm) yombhobho wensimbi, ixabiso lokuvelisa liphezulu, umyinge ophezulu kunombhobho wensimbi we-ERW 8% ukuya kwi-15%.

Umbhobho wentsimbi yeplanti enkulu kaninzi ayivelisi umbhobho wentsimbi ojikelezayo omncinci, ukuthengwa kunzima kakhulu.Idayamitha encinci kunye nephakathi ye-erw carbon steel pipe, ngenxa yenani elikhulu labavelisi, kulula kakhulu ukuyithenga.

Okwesine, umbhobho wentsimbi ubungakanani bejometri
I-1, i-ERW carbon steel pipe ye-geometric ubukhulu bokuchaneka okuphezulu;kunye ne-spiral welded weld geometry ukuchaneka kuphantsi, okukhokelela ekwakhiweni kwendawo yobunzima be-weld docking.
I-2, i-ERW carbon steel pipe weld coefficient yi-100%;umbhobho weld weld coefficient ye-130% -200%.Ubude bombhobho ojikelezayo bude kakhulu kunombhobho wensimbi we-ERW, kwaye izinga lesiphako liyanda.
I-3, i-ERW ibhobho yensimbi ye-carbon ngaphakathi kwe-weld isondele kwi-zero, iliso lingabonakali;umbhobho wensimbi ojikelezayo ngaphakathi nangaphandle komphezulu kufuneka ushiywe malunga ne-0.3 mm ukuphakama (okwenziwa yinkqubo yokuvelisa).I-weld iphezulu kangangokuba kukho umsantsa phakathi kwengubo (3PE) kunye nombhobho, okwenza ukuxhatshazwa kwe-corrosion yombhobho wensimbi kuncitshiswe kakhulu.

I-4, Ngenxa yobukho be-spiral i-gap yombhobho wensimbi, ukuhanjiswa kwe-high-speed fluid kuya kuba nokuphazamiseka okukhulu, ukwandisa ukuchasana kokuhamba, ukunciphisa ukusebenza kakuhle kokuthutha umbhobho.Udonga lwe-ERW carbon steel pipe lugudile, akukho ngxaki enjalo.
