Txheej txheem txheej txheem:

1. Plate Preparation: Cov txheej txheem ntawm kev tsim cov kav dej LSAW pib nrog kev npaj cov hlau phaj uas yuav siv rau hauv cov txheej txheem tsim khoom. Cov phiajcim raug ntxuav, tshuaj xyuas thiab cim rau kev txheeb xyuas thiab qhov chaw.

2. Ntug Milling: Cov npoo ntawm daim hlau yog tom qab ntawd milled kom ua tiav qhov vuam zoo. Qhov no yog ua los xyuas kom meej tias cov phaj tuaj yeem ua tiav welded ua ke thaum lub sijhawm tsim khoom.

3. Plate Forming: Cov phaj yog ces rhuab thiab tsim rau hauv U-puab siv lub tshuab nias nres. Cov phaj U-shaped ces muab tso rau ntawm kab sib dhos uas lawv tau welded ua ke siv submerged arc vuam.

4. Internal Vuam: Cov txheej txheem welding sab hauv suav nrog kev siv ntau yam vuam tshuab uas siv los vuam cov seams thiab npoo ntawm U-puab daim hlau ua ke. Cov txheej txheem pab tsim ib qho kev sib txuas txuas ntxiv uas muaj zog thiab ruaj khov.

5. Kev Vuam Sab Nraud: Cov txheej txheem vuam sab nraud suav nrog kev siv lub tshuab vuam uas siv los txuas rau sab nraud ntawm cov yeeb nkab. Cov txheej txheem yog ua los xyuas kom meej tias cov yeeb nkab yog du thiab tsis muaj qhov tsis xws luag.

6. Kev Ntsuas Ultrasonic: Tom qab cov txheej txheem vuam tiav lawm, kev kuaj ultrasonic yog ua kom ntseeg tau tias cov kav dej tsis muaj qhov tsis xws luag lossis tsis zoo. Kev ntsuam xyuas yog ua tiav los xyuas kom meej tias cov kav dej yuav tuaj yeem tiv taus qhov nruj ntawm kev thauj mus los thiab kev siv.

7. Txheej: Nyob rau theem kawg ntawm cov txheej txheem tsim, cov kav dej yog coated nrog ntau hom txheej xws li epoxy thiab polyurethane. Lub txheej yog ua los tiv thaiv cov kav dej los ntawm corrosion thiab lwm yam kev puas tsuaj.

Qhov zoo:

1. Lub zog muaj zog: ASTM A53 LSAW cov kav dej muaj lub zog tensile siab thiab tuaj yeem tiv taus kev kub siab thiab kev siv kub. Qhov no ua rau lawv haum rau kev lag luam xws li roj thiab roj, tshuaj lom neeg thiab petrochemical, thiab lwm yam.

2. Durability: Cov kav dej no yog tsim los siv cov hlau zoo uas tiv taus corrosion, xeb, thiab hnav thiab tsim kua muag. Qhov no ua kom lawv muaj lub neej ua haujlwm ntev thiab tuaj yeem tiv taus ib puag ncig hnyav.

3. Versatility: Cov kav dej ASTM A53 LSAW tuaj ntawm qhov sib txawv thiab qhov ntev. Qhov no ua rau lawv haum rau ntau yam kev siv, los ntawm cov phiaj xwm loj hauv kev lag luam mus rau kev siv me me hauv tsev.

4. Yooj yim rau nruab: Cov kav dej yog qhov yooj yim kom haum thiab nruab, uas ua rau cov txheej txheem ntawm kev teeb tsa lub raj xa dej los yog qhov system nrawm dua thiab ua haujlwm tau zoo.

5. Nqi-zoo: Cov kav dej yog cov nqi sib piv nrog rau lwm cov kev xaiv hauv khw. Qhov no ua rau lawv muaj kev xaiv nrov rau cov lag luam thiab cov tib neeg tab tom nrhiav kom txuag nyiaj ntawm lawv cov haujlwm.

6. Kev tu qis: Cov kav dej no yuav tsum tau saib xyuas tsawg thiab tuaj yeem ua haujlwm tau zoo rau xyoo tsis tas yuav kho lossis hloov pauv.

7. Ib puag ncig-phooj ywg: Cov kav dej yog tsim los ntawm cov khoom siv thiab cov txheej txheem, ua rau lawv muaj kev xaiv ruaj khov rau cov uas xav txo lawv cov pa roj carbon hneev taw.

Daim ntawv thov:

1. Kev lag luam roj thiab roj: ASTM A53 LSAW kav yog siv dav hauv kev lag luam roj thiab roj rau kev thauj mus los ntawm cov roj, roj, thiab lwm yam khoom siv roj av. Cov kav dej no muaj peev xwm tiv taus corrosion thiab tuaj yeem tiv taus siab thiab kub.

2. Kev Siv Dej: Cov kav dej ASTM A53 LSAW yog siv rau hauv cov khoom siv dej rau kev thauj mus los ntawm cov dej mus ntev. Cov kav dej no muaj zog heev thiab tuaj yeem tiv taus qhov hnyav ib puag ncig.

3. Kev Tsim Kho Kev Lag Luam: ASTM A53 LSAW kav yog siv rau hauv kev tsim kho kev lag luam rau kev thauj mus los ntawm cov khoom siv hauv tsev xws li pob zeb thiab hlau. Cov kav dej no muaj zog heev thiab tuaj yeem tiv taus qhov hnyav ntawm cov khoom hnyav.

4. Kev siv cov qauv: ASTM A53 LSAW kav yog siv rau hauv cov khoom siv xws li txuas hniav thiab cov tsev. Cov kav dej no muaj lub zog zoo heev thiab tuaj yeem nqa cov khoom hnyav.

5. Kev lag luam mining: ASTM A53 LSAW kav yog siv rau hauv kev lag luam mining rau kev thauj mus los ntawm cov ntxhia thiab lwm yam khoom siv. Cov kav dej no muaj zog heev thiab tuaj yeem tiv taus qhov chaw rugged.
