Khoom Ua Ntej Saib
Peb cov ASTM A182 F347 flanges yog forged los ntawm genuine 347 alloy thiab ua raws nruj me ntsis tag nrho ASTM A182 cov cai, kaw lub weld thiab tiv thaiv cracking. Furnace testing ntawm 650°C (raws li ASTM E21) tau qhia 85% retention ntawm room-temperature tensile strength (550-700 MPa), ua rau lawv zoo tagnrho rau high-temperature systems xws li boiler piping.
Cov Ntsiab Tseem Ceeb
Nyob rau hauv corrosion testing (ASTM B117 salt spray testing), lawv ua tau zoo tshaj ntau lwm yam stainless steel grades.
Peb muab ob yam surface finishes: pickled (per ASTM A380) kom tshem forge scale thiab txhim kho weldability, thiab 2B rolled finish.
Peb cov machining process yog precise: bolt holes yog CNC-drilled. Txhua flange tau ultrasonic testing (raws li ASTM E213) los tshuaj xyuas cov internal defects. Peb kuj teeb tsa plastic caps los tiv thaiv cov sealing surfaces thaum shipping.
Peb tau raw materials exclusively los ntawm certified steel mills. Txhua qhov incoming billet yog tshuaj xyuas siv peb lub direct-reading spark tester (OES).
Peb lub warehouse tuav 300-500 tons ntawm ASTM A182 F347 flanges npaj rau coiling. Qhov ntev los ntawm 1-inch beer line txog 36-inch jumbo flanges siv hauv refineries. Flanges tuaj yeem ntim hauv 5 hnub, tshem tawm qhov xav tau kev nrawm ua haujlwm thaum lub sij hawm tseem ceeb ntawm cov neeg siv khoom downtime.
Cov orders tshaj 40 tons tau txais 6% discount, free pickling, thiab 24% ocean freight coverage (shipping mus rau Rotterdam lossis Houston).
Peb lees paub: Yog tias ib lub ASTM A182 F347 flange tsis ua raws li ASTM A182 mechanical standards, peb yuav hloov nws hauv 7 hnub thiab refund tag nrho cov nqi shipping. Peb kuj kaw pricing rau 45 hnub tom qab koj qhov order tau lees paub, ua kom koj tsis raug kaw los ntawm kev hloov pauv ntawm khw.
