A chakna sang tak, pressure resistance leh welding property tha tak a neih avangin spiral steel pipe hi oil, gas, water conservancy, leh construction industry-ah te hman a ni nasa hle. Mahse, a performance advantages te chu a taka hman tangkai theih nan chuan hman dan dik tak hman a pawimawh hle. A hnuaia tarlan te hian installation, maintenance, welding, leh corrosion protection lam hawi a\\anga key spiral steel pipe hman dan tur tips a rawn tarlang a ni.
1. Installation tips: Stability leh alignment neih theihna tur .
Spiral steel pipe dah dawnin, pipe specification te chu project design nen a inmil em tih enfiah hmasa la, pipe body chu transportation emaw dahkhawlna avanga chhiatna awm leh awm loh enfiah hmasa phawt ang che. Install hmain pipe tawp te chu tifai la, burr leh welding slag te chu joint sealing tihchhiat loh nan. Butt-jointing i tih hian pipe axes te chu stress concentration thlentu forced splicing awm loh nan aligned a nih ngei ngei tur a ni. Large-diameter spiral steel pipe tan chuan installation pui turin butt-joint tool hman a tha a, a tawp te chu parallel a nih theih nan leh welding harsatna tihziaawmna tur a ni. Tin, pipe-in a rit emaw, a pawn lam thiltihtheihna emaw avanga bending tam lutuk emaw, deformation emaw a awm loh nan support point-te chu a dik taka dah tur a ni bawk.
2. Welding kalpui dan: Quality leh chakna control .
Spiral steel pipe connection te hi weld a ni fo a, weld quality hian pipe durability a nghawng nghal vek bawk. Weld hmain pipe ends chu uniform penetration a awm theih nan beveled a ngai a ni. Welding material \\ha tak tak (Low-Hydrogen electrode ang chi) leh process parameter (peran leh voltage ang chi) thlan a ngai a, thermal cracking awm loh nan interpass temperature chu khauh taka control a ngai a ni. Layer tam tak weld-naah chuan slag inclusion leh porosity awm loh nan slag layer khat hnu layer khatin la chhuak rawh. Welding zawhah chuan non-destructive testing (x{{6} emaw ultrasonic test emaw ang chi) a awm a, chu chu welds te chu defect awm lohna turin a ngai a ni.
3. Anti-Corrosion Measures: Service Life pawhsei .
Spiral steel pipe te hi hun rei tak chhung boruak lum leh hruihrual laka an awm chuan rust an nei awlsam a, anti-corrosion treatment a pawimawh hle. Anti- corrosion hman dan tlangpui chu epoxy coal tar coating, 3PE anti-corrosion coating, emaw galvanizing emaw a ni. Install hmain pipe body chu surface treated (sandblasting ang chi) a ni tur a ni a, chu chuan coating adhesion a enkawl tur a ni. Pipeline phum tur chuan electrochemical corrosion venna atan cathodic protection a ngai a ni. Chubakah, anti-corrosion coating chu chhiatna leh siamthat thuai a nih chuan steel pipe service life nasa takin a ti rei thei bawk.
4. Routine maintenance: Harsatna awm thei tur venna .
Operation neih chhung hian pipe support structure chu settling emaw pawn lam thiltihtheihna avanga deformation awm loh nan stability awm leh awm loh enfiah fo tur a ni. Corrosive media phurtu pipeline-te tan chuan internal wall corrosion chu enfiah a ngai a, a tul chuan pipe wall chu thlak emaw, a thim emaw a ngai bawk. Thlasik lai chuan temperature hniam takah chuan insulation measures a ngai a, chu chuan steel pipe chu a shrinkage vangin a chhe lo ang.
Heng spiral steel pipe hman dante hi mastering hian project himna a tichangtlung mai bakah maintenance cost pawh a ti tlem hle dawn a, hei hian pipeline system hun rei tak chhung stable taka a thawh theihna tur a tichiang dawn a ni.
