Khob hlau tau txais API 5L rite, peb tau npaj mus rau ntau qhov tebchaws, xws li Austria, New Zealand, Albania, Kenya, Nepal, Vietnam, thiab lwm yam.

Koj zoo, txhua tus. Peb lub koom tes yog ib tug hlau khoom muag ntau lub teb chaws. Nrog 17 xyoo muag tawm, peb ua lag luam nrog txhua hom lwm khoom, Kuv zoo siab rau kuv qhia cov khoom zoo tshaj. SSAW STEEL PIPE (Spiral hlau dej hlau) Tus khoom ua ntej kuv xav qhia yog SSAW dej hlau, spiral welded hlau dej hlau, uas yog tsim los ntawm peb lub tsev ua siab. Peb muaj peb lub teeb pom kev tsim khoom.

Cov loj tshaj plaws peb tuaj yeem tsim yog 3500mm, lub kaum ntawm 219mm mus rau 3500mm, ntau ntawm 3mm mus rau 35mm, cov ntev tseem ceeb yog 12m, cov ntev tshaj plaws peb tuaj yeem tsim yog 50m. ib txwm neeg sau kev xav tau 6m ntev, yog li peb tuaj yeem tsim raws li koj cov kev txiav txim.

peb tau txais API 5L, peb kuj muaj ISO 9000.

Cov standard thiab hlau peb tuaj yeem tsim raws li hauv lwm yam:

API 5L Qauv B,X42,X52,X70

GB/T 9711 Q235,Q355

EN10210 S235,S275,S355.

Pe cov koom tes hauv tsev phim kho, thiab tag nrho cov khoom siv los test, tuaj yeem ua cov neeg so qhov chaw tsis zoo, test nrog lawv hlais, saib nrog X-ray, NDT (Test tsis ua rau hnov), Charp V impact test, thiab test nrog cov hluav taws xob.

Peb kuj tuaj yeem pab kho qhov surface, xws li 3PE anti-corrosion panting, epoxy, thiab black painting.

Spiral pipe siv heev rau kev tiv thaiv tshuab tiv thaiv, cov nroj tshuab Hydro power, thiab cov nroj tshuab rau hauv nroj thiab rau ntawm qhov chaw hnyav. Hnub no, peb tau muag tawm cov khoom rau ntau lub teb chaws, xws li Austria, New Zealand, Albania, Kenya, Nepal,Vietnam, thiab lwm yam. Tshwj xeeb rau cov nroj tshuab Hydro power rau Albania thiab Nepal. Peb muaj cov duab ntawm cov neeg siv khoom.

Saum toj no yog peb cov nroj tshuab spiral steel pipe, thaum finished peb yuav ua test hauv tsev kho thiab test nrog tshuab, ob qhov kev test ua kom zoo dua. Tom qab ntawd peb yuav nqus cov nroj tshuab los rau hauv cov chaw nqus.

ERW STEEL PIPELub hom phaj thib ob yog ERW steel pipe. Muaj ob hom ERW steel pipe. Ib hom yog hot rolled steel pipe, hom ntxiv yog cold rolled steel pipe.

Kuv xav tias peb neeg siv khoom feem ntau yuav xav paub qhov sib txawv ntawm ob hom no. Kuv yuav qhia koj saib.

Hot rolled ERW pipe tus khoom raw material yog hot rolled steel coil, cold rolled steel pipe tus raw material yog cold rolled steel coil.

Diameter ntawm cov ntaub sau los ntawm kev ntxuav sov yog loj dua thiab qhov siab yog loj dua. Tus ntau tshaj plaws ntawm hot rolled pipe yog 660mm tab sis cold rolled pipe feem ntau yog ntau tshaj 4inch 114mm. Qhov siab ntawm hot rolled steel pipe yog ntawm 1mm txog 17mm, tab sis qhov siab ntawm cold rolled pipe feem ntau yog ntau tshaj 1.5mm.

cold rolled steel pipe yog qis dua thiab yoo ib yam los nqaj, piv txwv los tsim cov khoom siv hauv tsev, tab sis hot rolled steel pipe yog siv hauv qhov chaw loj. Tham kom pom cov duab ntawm peb tus neeg siv khoom, lawv siv cov cold rolled steel pipe los tsim cov khoom siv.

Peb tuaj yeem tsim cov ntev raws li koj xav.

Qhov chaw ntawm steel peb muaj tej

GB/T3091 Q195,Q235,Q355,

ASTM A53 Grade B

EN10219 S235 S275 S355

Kev lus nug tom ntej no yuav qhia koj txog peb cov galvanized pipe thiab square thiab rectangular pipe.
