Ipayipi lensimbi le-Q355 liyipayipi lensimbi eliphansi laseShayina elinamandla amakhulu esakhiwo, elithathe indawo ye-Q345, ukuminyana kwezinto kungu-7.85 g/cm3.Ngokusho kwe-GB/T 1591 -2018, i-Q355 inamazinga ekhwalithi angu-3: Q355B, Q355C kanye ne-Q355D.

I-Q355 steel pipe iyingxubevange ephansi, insimbi enamandla amakhulu esetshenziswa ezakhiweni ezishiselwe ezisekela ukucindezeleka nemithwalo esindayo.I-Q ibhekisela endaweni yokukhiqiza, kuyilapho inombolo engu-355 ibonisa amandla ayo okukhiqiza.

Izici ze-Q355 Steel Pipe

Ipayipi lensimbi le-Q355 liyinsimbi yesakhiwo enamandla okukhiqiza angama-345 MPa namandla aqinile angama-450 MPa.Inokusebenza okuhle kakhulu kokucubungula namandla acindezelayo, angasetshenziswa ukwenza imikhumbi yokucindezela kwegesi ephezulu equkethe amalitha angaphansi kwama-500.I-Q355 nayo inongqimba oluvikelayo lokumelana nokugqwala.

Ukusetshenziswa kwe-Q355 Steel Pipe

Ipayipi lensimbi le-Q355 linezinto ezinhle kakhulu zokusebenza, ukushisela okukhulu, nokumelana nokugqwala okwanele.Ingasetshenziselwa ukukhiqiza nokukhiqiza amathangi okugcina uphethiloli, imikhumbi enengcindezi ephezulu, amabhayela, imikhumbi, iziteshi zikagesi, nezinye izingxenye eziningi zesakhiwo esinomthwalo omkhulu.

Ubukhulu: 34mm-610mm.

I-WT: 3.5mm-50 mm.

Isimo: Indilinga.

Uhlobo lokukhiqiza: Okugoqiwe okushisayo noma Okushisayo kusetshenziswe isikhathi eside .

Ubude: Ubude obungahleliwe obukodwa/ Ubude obungahleliwe obuphindwe kabili noma ubude besicelo sangempela sekhasimende bungama-12m

Ukuqondisa

Ngemuva kokukhishwa kwe-annealing, izimpahla zidluliselwa ngomshini wokuqondisa ama-roller ayisikhombisa ukuze kuzuzwe ukuqondisa okufanele kwamashubhu.

Eddy okwamanje

Ngemuva kokuqondisa, ishubhu ngalinye lidluliswa emshinini wamanje we-eddy ukuze kutholwe ukuqhekeka kwendawo nokunye ukonakala.Amashubhu kuphela adlula i-eddy current afanele ukuthunyelwa kumakhasimende.

Ukuqeda

Ishubhu ngalinye ligcotshwe ngamafutha amelana nokugqwala noma lifakwe ivanishi ukuze livikeleke futhi limelane nokugqwala ngokwesidingo samakhasimende, isiphetho seshubhu ngalinye simbozwa ngamakepisi epulasitiki ukuze kugwenywe umonakalo osendleleni, ukumaka kanye nemininingwane iyafakwa futhi izimpahla zilungele ukuthunyelwa. .

Isicelo

I-Q355 Amapayipi ensimbi angenamthungo e-Hot Rolled Carbon asetshenziswa kakhulu emshinini wenuzi, ukuthutha igesi, i-petrochemical, i-shipbuilding kanye nezimboni zamabhayela, anezici zokumelana nokugqwala okuphezulu kuhlanganiswe nezakhiwo ezifanele zemishini.
