Seamless steel cylinder siamna hmanrua te
Seamless steel gas cylinder siam dan zawng zawng: billet blanking → heating → hot extrusion/spinning forming → bottom closing → bottle mouth processing → heat treatment → water pressure test → air tightness test → surface treatment → flaw detection → printing logo, hei hi mainstream route pahnih-ah then a ni a: hot extrusion process leh spinning process.
A hmasa berin, blank pretreatment section chu a awm

3. Inspection hmanrua (billet ultrasonic inspection): raw material bar chhunga chhiatna awmte screening.
Pahnihnaah chuan, hot forming core section (mainstream process pahnih) Route A: Hot extrusion (a tlangpuiin lian-volume seamless steel cylinder-a hman thin)
1. Annular heating furnace/intermediate frequency induction heating furnace: round billet chu forging temperature 11001250℃thlenga tihlum tur a ni.
2. Hydraulic extruder: high-pressure extrusion, chu chu hot blank chu hollow cylindrical blank-ah extrude a ni.
3. Bottom press (bottom-closing press): Bottle hnuai lam chu hrual la, khar rawh.
4. Bottle neck rotary forging machine: a tawp khat forge la, bottle hmui kawng chu process rawh. Route B: Spinning forming (steel cylinder te tak te leh lian te, oxygen cylinder leh nitrogen cylinder te tan hman tlanglawn tak)
1. Plasma pipe cutter: steel pipe chu a sei zawnga tan a ni a, steel cylinder blank chu a cut bawk.
2. Intermediate frequency heating furnace: tube blank awmna hmuna tihlum.
3. Spinning machine chak tak: hollow tube blank chu spinning leh thinning a, bottle body siam nan; Bottom-closing spinning leh necking spinning chu a inthen a, bottle hnuai lam sealing leh bottle mouth necking chu vawi khatah tihfel a ni. Tip: Seamless steel cylinder hian welding process a nei lo va, bottle hnuai lam chu extrusion/spinning hmangin a khar vek a ni. Pathumnaah chuan machining section a ni
1. CNC lathe/special bottle mouth machine tool: bottle hmui thread leh sealing surface processing, leh bottle hnuai lam shape processing.
2. Thread gauge inmil: bottle mouth thread enfiahna hmanrua. Pali, heat treatment section (gas cylinder-te mechanical property hriatfiah, a pawimawh) 1. Continuous heat treatment furnace: quenching leh tempering chu a chakna leh toughness a awm theih nan Matching quenching cooling system (tui tihlum/oil tihlum) a ni. Panga, nondestructive testing section a ni
1. Ultrasonic flaw detector: bottle body chhunga wall thickness leh internal cracks te chu a hriat theih.
2. Magnetic particle flaw detector: chhung lam leh pawn lam chunglam a chhe (ferromagnetic steel cylinder tan standard) .
3. Bottle hmui atana flaw detection hmanrua bik: threaded part-a crack enfiah. Paruk, pressure test section (a himna enfiah ngei ngei tur)
1. Hydrostatic testing machine: compression chakna test, leh ram pum huap standard angin hydraulic blasting hmaa compression test.
2. Air-tight testing machine: leak hriat theihna turin compressed air/nitrogen fill; Gas cylinder hnuai lama air tightness testing machine: compressed air leh sahbawn tui fill la, gas cylinder hnuai lam a leak leh leak loh enfiah rawh.
3. Residual moisture drying equipment: test zawhah bottle chhunga tui awmkhawm chu a vawt vek tur a ni. VII. Surface leh Post-treatment tih a ni
1. Gas cylinder pawn lam bang atana shot blasting machine: gas cylinder pawn lam atanga heat-treated scale paih chhuah; Gas cylinder chhung lam bang atan shot peening machine: gas cylinder chhung lam a heat treatment scale chu paih chhuak rawh.
2. Spraying siamna line (electrophoresis/painting siamna line): pawn lam wall duty paint.
3. Furnace vawt leh tihthianghlim: paint vawt.
4. Cylinder marking machine (steel engraving machine): steel seal chhinchhiahna engraving number, tui pressure date leh working pressure te a awm.
5. Drying equipment: a chhunga hnim hring lo turin bottle chhunga vawt.
6. Cylinder valve loader: cylinder valve dah tur a ni. Pariat, puitu hmanrua -Hydraulic station, high-pressure water pump, compressed air system leh nitrogen gas source. -Physical leh chemical laboratory hmanrua: tensile testing machine, impact testing machine, hardness tester, mechanical property atana sample batch tin. -Blasting test bench (type test, destructive blasting test tih a ni irregularly) Hriat nawn tirna pawimawh tak
1. Seamless steel cylinder hi hmanraw bik a ni a, chu chu hmanrua lei atanga siam theih a ni lo. Thil hmanraw bik siamna license a neih a ngai a, a kalphung leh enfiahna system zawng zawng hian ram pum huap standard GB 5099 a tlin a ngai a ni.
2. Production line pumpui investment a tam hle a, hot extrusion/large-scale powerful spinning machine pakhat man pawh a to hle a, physical, chemical leh nondestructive testing laboratory kimchang tak pawh a ngai bawk.
