I-DIN2391 ST45 Umbhobho wentsimbi obandayo oZotywayo ongenamthungo

I-DIN2391 ST45 Umbhobho wentsimbi Ozotyiweyo obandayo ongenamthungo oboniswa ngumfanekiso

Inkcazelo emfutshane:

Umbhobho wentsimbi ongenamthungo otsaliweyo wenziwa ngomngxuma wentsimbi ongenamthungo.Iphinde iqhutywe ngumzobo obandayo phezu kwe-mandrel, ukulawula i-ID, kwaye ngokufa ukulawula i-OD.I-CDS iphezulu kumgangatho womphezulu, ukunyamezela kwe-dimensional kunye namandla xa kuthelekiswa ne-tubing eshushu egqityiweyo engenamthungo.Ngenxa yeempawu zokuchaneka okuphezulu, kwimveliso yomatshini ochanekileyo, iinxalenye zemoto, iisilinda ze-hydraulic, imboni yokwakha (i-steel sleeve) inoluhlu olubanzi kakhulu. yezicelo.

Ubukhulu: 16mm-89mm.

WT: 0.8mm-18 mm.

Ubume: Round.

Uhlobo lokuvelisa: Ukutsalwa ngokubanda okanye ukubanda kuqengqeleke.

Ubude: Ubude obubodwa obungacwangciswanga / Ubude obuphindwe kabini obungenamkhethe okanye njengesicelo somthengi sokwenyani ubude buyi-10m

Ukuhlaziya

Emva kokuba iimpahla zibande zitsalwa ngokwesayizi, iityhubhu zifakwa kwisithando somlilo sokunyanga ubushushu kunye nokulungisa.

Ukolulwa

I-post annealing, iimpahla zigqithiswa kumatshini wokulungelelanisa we-roller ezisixhenxe ukuze kuphunyezwe ukulungiswa okufanelekileyo kweetyhubhu.

Eddy yangoku

Ukolulwa kwesithuba, ityhubhu nganye idlula kumatshini we-eddy wangoku ukubona iintanda kunye nezinye iziphene.Iityhubhu kuphela ezidlula i-eddy current zilungele ukuhanjiswa kubathengi.

Ukugqiba

Ityhubhu nganye ifakwe i-oyile enganyangekiyo okanye inevanishi yokukhusela umphezulu kunye nokunganyangeki kwe-corrosion ngokwemfuno yabathengi, isiphelo setyhubhu nganye sigqunywe ngee-caps zeplastiki zokuphela kokuphela kokuphela komonakalo, ukumakishwa kunye ne-specs zibekwe kwaye iimpahla zilungele ukuthunyelwa. .
