Spiral welded steel yeeb nkab

Kauv welded steel yeeb nkab tseem hu ua kauv steel yeeb nkab thiab kauv welded yeeb nkab, uas yog siv qis carbon structural steel los yog tsis tshua muaj alloy steel sawb raws li lub kaum sab xis ntawm cov kauv kab (hu ua lub kaum sab xis) dov mus rau hauv ib lub raj, thiab ces. lub raj welded ua ke ua, nws yuav ua tau ib tug nqaim sawb zus tau tej cov loj txoj kab uas hla steel yeeb nkab.Lub kauj yog tsuas yog siv rau roj thiab roj pipelines, nws specifications OD * phab ntsa thickness.Sab welding thiab ob-sided welding kauv welded yeeb nkab yuav tsum xyuas kom meej tias qhov kev sim hydrostatic, lub zog tensile ntawm vuam thiab txias dabtsi yog khoov kev ua tau zoo.

(1) Cov kua dej siab xa mus rau kauv submerged arc welded yeeb nkab: feem ntau yog siv rau kev thauj cov roj, cov raj xa dej;

(2) Lub siab ua kua dej sib kis tau siab zaus welded steel kav nrog kauv seam: welded high-frequency lap welding txoj kev rau siab cov kua xa mus kauv high-frequency welded steel yeeb nkab.Muaj peev xwm ntawm cov yeeb nkab steel nyob rau hauv siab, zoo plasticity, yooj yim ntawm vuam thiab molding txheej txheem;

(3) Cov kua dej tsis tshua muaj kev sib kis tau muab kauv submerged arc welded steel yeeb nkab: ob-sided tsis siv neeg submerged arc vuam lossis ib leeg-ib sab vuam rau hauv txoj cai lij choj rau cov kua dej tsis tshua muaj xws li dej, roj, cua thiab chav nrog submerged arc welded yeeb nkab.

Seamless yeeb nkab khoom yam ntxwv:
1. seamless raj txheej txheem kev xeem: flattening test, tensile xeem, cuam tshuam kuaj, flaring test, hardness test, metallographic xeem, dabtsi yog khoov xeem, nondestructive xeem (xws li eddy tam sim no X-ray thiab ultrasonic kuaj).

2.Seamless yeeb nkab tshuaj ntsuam xyuas: cov tshuaj muaj pes tsawg leeg ntawm cov khoom siv tshuaj ntsuam xyuas, tshuaj muaj pes tsawg leeg kom ua tau raws li tus qauv yuav tsum tau ua.

3.Seamless yeeb nkab siab thiab hydrostatic test yog rau siab raj los ntawm kev ntsuam xyuas hydrostatic, uas tsis tuav lub siab tus nqi tsis pub tsawg tshaj li 5 vib nas this, tsis txhob nthuav tawm, cov khoom tsis tu ncua hydraulic siab ntsuas yog 2.45MPa siab Qhov ntsuas siab yog P = 0.5MPAa.

4.Qhov kev ntsuam xyuas corrosion: muaj corrosion-resistant steel yeeb nkab raws li tus qauv kev cai lossis kev pom zoo ntawm cov yeeb nkab steel corrosion kuj kuaj, tsis muaj intergranular corrosion.

Cov yam ntxwv ntawm seamless yeeb nkab
(1) sab nraud yog me dua.

(2) High precision yuav ua tau me me ntawm raw.

(3) txias kos steel yeeb nkab nrog siab precision thiab zoo nto zoo.

(4) steel yeeb nkab hla cheeb tsam yog qhov nyuaj dua.

(5) steel yeeb nkab superior kev ua tau zoo, kuj ntom hlau.
