9711.1 iSpiral Steel Pipe

Imibhobho e-Spiral isetyenziswa ikakhulu kwimibhobho yeoli neyerhasi yendalo, kwaye iinkcukacha zayo zibonakaliswa ngedayamitha engaphandle * ubukhulu bodonga.Imibhobho ejikelezayo inokudityaniswa kwicala elinye okanye macala omabini.Umbhobho odityanisiweyo uya kuqinisekisa ukuba uvavanyo loxinzelelo lwamanzi, ukuqina kokuqina kwe-weld kunye nokusebenza kokugoba okubandayo kuyahlangabezana neemfuno.

Indlela yonyango yomphezulu:
1. Ukucoca
I-solvents kunye ne-emulsions zisetyenziselwa ukucoca ubuso bentsimbi ukususa ioli, igrisi, uthuli, i-agent egudileyo kunye ne-organic matter efanayo, kodwa ayikwazi ukususa i-rust, i-oxide scale, i-welding flux, njl. isetyenziswe njengenyathelo elincedisayo kwimveliso yokulwa nokubola.

2. Izixhobo zokususa umhlwa
Okokuqala, sebenzisa iibrashi zocingo kunye nezinye izixhobo zokupolisha umphezulu wentsimbi, ezinokususa i-oxid scale, i-rust, i-welding slag, njl njl. umgangatho we-Sa3.

3. Ukukha
Ngokuqhelekileyo, iindlela ezimbini zeekhemikhali kunye ne-electrolysis zisetyenziselwa ukukha.I-anticorrosion ye-pipeline isebenzisa kuphela i-chemical pickling, enokuthi isuse isikali se-oxide, i-rust, kunye neengubo ezindala.Ngamanye amaxesha inokusetyenziswa njenge-sandblasting kunye nokususa umhlwa.Ukucocwa kweekhemikhali ngokuqinisekileyo kunokukwenza ukuba ukubonakala kufikelele kwinqanaba elithile lokucoceka kunye noburhabaxa, kodwa ipateni yayo ye-anchor ayinzulu, kwaye kulula ukungcolisa imeko.

4. Ukutshiza (ukuphosa) ukususa umhlwa
Ukutshiza (ukuphosa) ukususwa komhlwa yi-motor enamandla kakhulu eqhuba ukutshiza (ukuphosa) ii-blades ukujikeleza ngesantya esiphezulu, ukwenzela ukuba i-grit yentsimbi, i-steel shot, icandelo locingo lwentsimbi, iiminerali kunye nezinye iziqhumiso zitshizwe (ziphoswe) ubuso bombhobho wensimbi phantsi kwempembelelo ye-centrifugal force., Akunakuphela nje ukuphelisa ngokupheleleyo i-rust, i-oxides kunye nokungcola, kodwa kunye nombhobho wensimbi unokufikelela kumyinge ofunekayo wobunzima obufunekayo phantsi kwefuthe leempembelelo ezinobukrakra kunye ne-friction ye-abrasive.
Emva kokutshiza (ukuphosa) ukususa i-rust, kungekhona nje ukuba umphumo we-adsorption womzimba womhlaba wombhobho unokwandiswa, kodwa kunye nomphumo wokubambelela kumatshini we-anti-corrosion layer kunye nomphezulu wombhobho unokuqiniswa.Ngoko ke, ukutshiza (ukuphosa) ukususwa komhlwa yeyona ndlela ifanelekileyo yokususa umhlwa kumbhobho wokunqanda ukubola.Ngokuqhelekileyo, ukudutyulwa kokudubula (isanti) ukususwa komhlwa kusetyenziswa ikakhulu kunyango lwangaphakathi nangaphandle komphezulu wombhobho, kunye nokudubula okuqhushumba (isanti) ukususwa komhlwa kusetyenziswa ikakhulu kunyango lomphezulu wombhobho.
