Cov yeeb hlau carbon steel line yog cov kav dej tshwj xeeb siab thiab qis uas thauj ntau yam kua xws li roj, roj av, dej tob, thiab lwm yam uas tau rho tawm hauv av mus rau cov khoom ua haujlwm. Lawv muab faib ua cov yeeb hlau seamless thiab welded, thiab txuas los ntawm kev vuam qhov kawg, clamps, sockets, xov, thiab lwm yam.
- Kev tiv thaiv corrosion zoo. Phab ntsa sab hauv ntawm cov yeeb hlau tau kho los ntawm kev txau, composite lining thiab lwm cov txheej txheem kom tiv tau corrosion thiab oxidation.
- Kev tiv thaiv siab siab. Qib siab tuaj yeem siab tshaj Class1500/40mpa/3000psi, thiab tuaj yeem tiv tau lub siab thauj khoom.
- Kev nyab xeeb siab. Txhawm rau kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom thauj, phab ntsa tuab yuav raug ntsuas nruj.
- Lub zog tensile siab. Nws muaj zog thiab toughness zoo. Lub zog tensile tuaj yeem ncav 850MPa lossis ntau dua.

Cov Txiaj Ntsig Tseem Ceeb
Cov qib alloy muaj zog siab ua kom muaj peev xwm thauj ntev thiab siab; cov kav dej welded muaj nqis zoo rau cov haujlwm loj; cov kev xaiv coated txuas ntxiv kev pab cuam hauv av corrosive/dej hiav txwv; ntau yam rau ntau cov kua
Cov Lus Nug Nquag Nug
Nug: Koj puas tuaj yeem muab daim ntawv pov thawj keeb kwm (CO) rau kev tshem tawm?
Tej: Yog, peb tuaj yeem muab CO, nrog rau lwm cov ntaub ntawv xws li daim ntawv them nyiaj thiab cov ntawv ntim khoom uas xav tau rau kev tshem tawm.
Nug: Koj ua li cas ntim cov khoom kom tsis txhob puas thaum xa khoom?
Tej: Peb siv cov ntim khoom haum rau kev xa dej hiav txwv: cov khoom me hauv cov thawv los yog cov thawv ntoo, thiab cov khoom loj hauv cov thav hlau lossis pallets nrog ntawv yas tiv thaiv dej.
Nug: Koj txoj cai rau kev xa rov qab lossis hloov khoom yog dab tsi?
Tej: Yog tias cov khoom muaj teeb meem zoo los ntawm peb, peb yuav npaj hloov lossis them nyiaj rov qab hauv 30 hnub tom qab tau txais.
