IDiameter enkulu yeKhabhoni eWelded Spiral Steel Pipe

Inkcazelo emfutshane:

Umbhobho odityanisiweyo we-Spiral: Wenziwa ngentsimbi ephantsi-carbon carbon structural steel okanye i-low-alloy structural strip yentsimbi eqengqeleke kwibillet yombhobho kwi-engile ethile ye-spiral line (ebizwa ngokuba yi-engile yokubumba), kwaye ke umthungo wombhobho udityaniswe kunye, othi inokuvelisa umbhobho omkhulu wentsimbi ukusuka kwintsimbi emxinwa.Ukucaciswa kwayo kubonakaliswa yi-diameter yangaphandle * ubukhulu bodonga, umbhobho odityanisiweyo kufuneka uqinisekise ukuba uvavanyo lwe-hydraulic, amandla okuqina e-weld kunye neempawu zokugoba ezibandayo ukuhlangabezana nezibonelelo.

Iimpawu ze-Metallurgical zezinto eziphathekayo

Imibhobho edityanisiweyo ye-arc yobude be-arc edibeneyo iveliswa kwiipleyiti zentsimbi, ngelixa imibhobho e-spiral edityanisiweyo iveliswa kwiikhoyili ezishushu.Inkqubo yokugoqa iyunithi eshushu-eshushu ineenzuzo ezininzi kwaye inekhono lenkqubo ye-metallurgical ukufumana ukuveliswa kwentsimbi yombhobho ophezulu.Ngokomzekelo, i-output stand ixhotyiswe ngenkqubo yokupholisa amanzi ukukhawulezisa ukupholisa, okuvumela ukusetyenziswa kweengoma ze-alloy ephantsi ukuphumeza amabakala anamandla akhethekileyo kunye nobunzima obuphantsi kobushushu, ngaloo ndlela kuphuculwe i-weldability yentsimbi.Nangona kunjalo, le nkqubo ayikho kakhulu kwizityalo zokuvelisa sheet sheet.Umxholo we-alloy (okulingana nekhabhoni) yeekhoyili zihlala ziphantsi kunezibakala ezifanayo zeepleyiti zentsimbi, eziphucula ukuwelda kwemibhobho edityanisiweyo.

Okubaluleke ngakumbi ukuba kuqatshelwe kukuba, ngenxa yokuba i-spiral welded pipe coil rolling direction ayikho perpendicular ukuya kwicala lentsimbi yombhobho wentsimbi (isisombululo sayo sixhomekeke kwi-spiral angle yombhobho wentsimbi), lo gama umthungo othe tye umbhobho wentsimbi isalathiso perpendicular ukuya kwicala lentsimbi umbhobho axis, kwaye ngaloo ndlela, spiral welded umbhobho imathiriyeli ingcono kunomthungo othe ngqo umbhobho intsimbi ukuxhathisa ukuqhekeka.

Inkqubo yeWelding

Ukusuka kwinkqubo welding, spiral welded umbhobho kunye umthungo othe tye intsimbi umbhobho welding indlela iyafana, kodwa umthungo ngqo welding umbhobho ngokuqinisekileyo uya kuba ne-ding weld eninzi, ngoko ke amathuba okuwelda ayanda kakhulu, kunye noxinzelelo olushiyekileyo lwe-welding. kwi-ding weld inkulu, isinyithi se-weld sihlala sikwimeko yoxinzelelo lweendlela ezintathu, ukwandisa amathuba okuqhekeka.

Ngaphezu koko, ngokwenkqubo ye-arc ye-welding ephantsi kwamanzi, i-weld nganye kufuneka ibe kwi-arc initiation kunye nokucima i-arc, kodwa umthungo ngamnye othe tye odityanisiweyo wombhobho kumthungo odibeneyo we-annular, awukwazi ukufikelela kwimeko, ngoko ke kunokubakho iziphene zokuwelda kwi-arc. ukucima.
