Isebenza ngokuthe ngqo ngabavelisi bemibhobho yentsimbi ejikelezayo kwiindawo zokwakha
Imigangatho eqhelekileyo yombhobho wentsimbi ejikelezayo yahlulwe ngokubanzi: SY / t5037-2008 (umgangatho womphathiswa, okwaziwa ngokuba yi-spiral submerged arc welded steel pipe kumbhobho wokuhambisa ulwelo oluqhelekileyo), GB / t9711.1-2008 (umgangatho wesizwe, owaziwa nangokuthi njengeemeko zonikezelo zobugcisa zothumelo lwentsimbi yombhobho weoyile kunye negesi, icandelo I: iklasi umbhobho wentsimbi (GB / t9711.2 iklasi B umbhobho wentsimbi kunye neemfuno ezingqongqo)), api-5l (American Petroleum Association, eyaziwa ngokuba yintsimbi yombhobho. umbhobho); Kubandakanya i-PSL1 kunye ne-PSL2), i-SY / t5040-2008 (i-spiral welded steel pipe ye-pile).
I-SY / t5037-2008 ngumgangatho obekwe nguMphathiswa wepetroleum, obizwa ngokuba ngumgangatho wobulungiseleli.
I-GB / t9711.1-2008 yombhobho wesizwe ojikelezayo, umbhobho wentsimbi wokuhanjiswa kwepetroleum kunye negesi yendalo, iklasi A.
Umbhobho wentsimbi odityanisiweyo we-Spiral-frequency high-frequency welded steel (sy5039-2000) kuthutho oluphantsi loxinzelelo oluphantsi jikelele uthatha ikhoyili yomtya wentsimbi eshushu eqengqelekisiweyo njengombhobho ongenanto, osoloko ushushu ukubunjwa kwe-spiral, kwaye isebenzisa indlela yokuwelda i-high-frequency lap ukuwelda i-spiral seam ephezulu- umbhobho wentsimbi odityanisiweyo wokuthuthwa ngokubanzi koxinzelelo oluphantsi.
Umbhobho wentsimbi odityanisiweyo we-Spiral wengqumba (sy5040-2000) yenziwe nge-coil yentsimbi eshushu eqengqelekisiweyo njengombhobho ongenanto, odla ngokufudumala ukwenza i-spiral, ukuwelda kwe-arc kumacala amabini okanye i-high-frequency welding. Isetyenziselwa umbhobho wentsimbi kwimfumba yesiseko yesakhiwo sokwakha, i-wharf, ibhulorho njalo njalo. Ukuthuthwa kolwelo olucinezelekileyo, i-spiral submerged arc welded steel pipe sy5036-2000 isetyenziswa, esetyenziswa ikakhulu kwimibhobho yokuthutha ioyile kunye negesi yendalo;
I-Spiral seam ye-high-frequency welded steel pipe sy5038-2000 yokuhambisa ulwelo loxinzelelo, oludityaniswe yindlela ye-welding ye-high-frequency lap kwaye isetyenziselwa ukuhanjiswa koxinzelelo. Umbhobho wentsimbi unamandla oxinzelelo olunamandla kunye neplastiki efanelekileyo, ekulungele ukuwelda kunye nokusebenza;
Kuthutho lolwelo olunoxinzelelo oluphantsi jikelele, i-spiral seam entywilayo ye-arc welded steel pipe sy5037-2000 iyasetyenziswa, kunye nombhobho wentsimbi odityanisiweyo we-arc wokuhambisa ulwelo olunoxinzelelo olusezantsi olunje ngamanzi, igesi, umoya kunye nomphunga wenziwa ngamacala amabini azenzekelayo. ukuwelda kwe-arc emanzini okanye ukuwelda kwicala elinye.
