Spiral welded steel pipe

Spiral welded steel pipe e boetse e tsejoa e le spiral steel weld pipe le spiral welded pipe, e leng tshebediso ya tshepe e tlase ya khabone kapa lesela le tlase la alloy ho latela angle ya spiral (e bitsoang angle angle) tube welded hammoho entseng, e ka ba e moqotetsane hlobolisa tlhahiso ea phala e khōlō bophara tšepe.Coil e sebelisoa haholo bakeng sa liphaephe tsa oli le khase, litlhaloso tsa eona OD * botenya ba lebota.Side tjheseletsa le mahlakoreng a mabeli tjheseletsa spiral tjheseletsa phala lokela ho etsa bonnete ba hore teko hydrostatic, tensile matla a tjheseletsa le batang kobang tshebetso hlokahala.

Litšobotsi tsa sehlahisoa sa seamless pipe:
1. Teko ea ts'ebetso ea seamless tube process: teko ea ho batalla, teko ea tsitsipano, tlhahlobo ea phello, teko ea ho phatloha, teko ea boima, tlhahlobo ea metallographic, teko ea ho khumama, tlhahlobo e sa senyeheng (ho kenyeletsoa X-ray ea hona joale ea Eddy le tlhahlobo ea ultrasonic).

2.Seamless pipe chemical analysis: lik'hemik'hale tsa lisebelisoa bakeng sa tlhahlobo ea lik'hemik'hale, lik'hemik'hale ho finyella litlhoko tse tloaelehileng.

3.Seamless pipe khatello le tlhahlobo ea hydrostatic ke bakeng sa tube ea khatello ka ho kena tekong ea hydrostatic, e sa boloke boleng ba khatello e behiloeng e seng ka tlase ho metsotsoana ea 5, hore e se ke ea senola, tlhahlobo e tloaelehileng ea khatello ea hydraulic khatello ke 2.45MPa khatello Teko ea khatello ke P = 0,5MPAa.

4.Teko ea kutu: phala ea tšepe e sa sisinyeheng ea liindasteri ho latela melao e tloaelehileng kapa tumellano pakeng tsa teko ea ho hanyetsa lipeipi tsa tšepe, ha ho na intergranular corrosion.

Litšobotsi tsa phala e se nang moeli
(1) bophara bo ka ntle bo nyane.

(2) Ho nepahala ho phahameng ho ka etsa lintho tse fokolang tse tala.

(3) phala e batang ea tšepe e huloang ka mokhoa o nepahetseng o phahameng le boleng bo botle ba bokaholimo.

(4) tšepe phala sefapano sebakeng se rarahaneng ho feta.

(5) ts'ebetso e phahameng ea phala ea tšepe, tšepe e batlang e le boima.
