ASTM A106 (M) yog tus qauv tshwj xeeb rau seamless carbon steel yeeb nkab rau kev pabcuam kub. Qhov kev qhia tshwj xeeb no suav nrog cov kav dej uas tsim nyog rau kev khoov, flanging, thiab kev ua haujlwm zoo sib xws, nrog rau kev siv vuam. Cov hlau siv hauv kev tsim cov kav dej no yog qhov zoo tshaj plaws, kom ntseeg tau tias lawv tuaj yeem tiv taus qhov kub thiab txias.

ASTM A106 (M) specification yog dav siv hauv kev lag luam roj thiab roj, nrog rau lwm yam kev lag luam uas yuav tsum tau muaj cov kav dej kub. Cov kav dej muaj nyob rau hauv ntau qhov sib txawv thiab tuab, ua rau lawv haum rau ntau yam kev siv. Lawv kuj muaj nyob rau hauv cov qib sib txawv, nrog rau Qib B yog cov feem ntau siv.

Yuav kom paub meej, ASTM A106 Qib B Pipe (tseem hu ua ASME SA106 GR.B yeeb nkab) yog siv rau hauv cov chaw tsim hluav taws xob, boilers, petrochemical nroj tsuag, roj thiab roj refineries, thiab cov nkoj uas cov kav dej yuav tsum thauj cov dej kub lossis txias thiab cov pa hauv qab. kub siab thiab kub. A106 GR.B Carbon Steel Seamless Pipe muaj nyob rau hauv ntau qhov hnyav, qhov ntau thiab tsawg, thiab qib dub thiab galvanized ob leeg seamless thiab hluav taws xob welded. ASTM A106 Qib B Yeeb Nkab qhov ntau thiab tsawg, tsawg dua 2 "feem ntau yog xa tawm raws li cov khoom lag luam txias.

Ntxiv mus, ASTM A106 Qib C Yeeb Nkab (tseem hu ua ASME SA106 GR.C yeeb nkab) yog carbon-manganese steel yeeb nkab rau qhov kub thiab txias loj-inch boilers thiab superheaters. Nws cov tshuaj muaj pes tsawg leeg yog yooj yim thiab zoo ib yam li 20G carbon steel, tab sis nws cov pa roj carbon thiab manganese cov ntsiab lus siab dua, yog li nws lub zog tawm los yog li 12% siab dua li ntawm 20G, thiab nws cov plasticity thiab toughness tsis phem. Cov hlau muaj cov txheej txheem tsim khoom yooj yim thiab ua haujlwm txias thiab kub ua haujlwm. Siv nws los hloov 20G headers (economizer, phab ntsa dej, low-temperature superheater thiab reheater header) tuaj yeem txo cov phab ntsa thickness li ntawm 10%, uas tuaj yeem txuag cov nqi khoom, txo cov khoom siv vuam, thiab txhim kho kev ua haujlwm ntawm headers.

Piv nrog rau cov qib ib txwm, ASTM A106 Qib C Yeeb Nkab yog qhov muaj zog heev rau kev siv dav thiab hauv zos corrosion. Cov kav dej no muaj kev tiv thaiv zoo rau pitting thiab crevice corrosion nyob rau hauv qhov chaw tsis zoo. Dab tsi ntxiv, cov kav dej no nyiam rau halide thiab chloride uas muaj ib puag ncig hauv qhov kub thiab txias. Nws muaj cov yam ntxwv zoo xws li lub zog nkag siab dua, kev ntxhov siab rau lub zog tawg, lub zog tensile thiab ntau ntxiv. Advantageously, nws yog heev tiv taus atmospheric corrosion.

Ib qho ntawm cov yam ntxwv tseem ceeb ntawm ASTM A106 (M) cov kav dej yog lawv lub peev xwm tiv taus qhov kub thiab txias. Qhov no yog ib qho tseem ceeb nyob rau hauv daim ntawv thov uas cov kav dej raug tshav kub heev, xws li nyob rau hauv boilers thiab tshav kub exchangers. Cov kav dej kuj tau tsim los tiv thaiv kev kub ntxhov, ua rau lawv tsim nyog siv rau hauv cov ntawv thov uas lub siab yog qhov tseem ceeb.

ASTM A106 (M) cov kav dej yog tsim los siv ntau yam txheej txheem, suav nrog kub dov, kos duab txias, thiab txias dov. Cov txheej txheem tsim khoom siv yog nyob ntawm qhov xav tau ntawm cov yeeb nkab thiab daim ntawv thov uas nws yuav siv. Tom qab ntawd cov kav dej raug kuaj xyuas kom ntseeg tau tias lawv ua tau raws li qhov yuav tsum tau ua ntawm ASTM A106 (M) specification.

Ntxiv nrog rau lawv qhov kub thiab txias muaj peev xwm, ASTM A106 (M) cov kav dej kuj paub txog lawv cov kev tiv thaiv corrosion. Qhov no yog ib qho tseem ceeb nyob rau hauv daim ntawv thov uas cov kav dej raug rau corrosive tshuaj, xws li acids thiab ntsev. Cov kav dej kuj tseem tiv taus oxidation, uas tuaj yeem ua rau lawv tsis zoo rau lub sijhawm.

Zuag qhia tag nrho, ASTM A106 (M) cov kav dej yog qhov kev xaiv ruaj khov thiab ruaj khov rau kev siv cov kav dej kub. Lawv muaj peev xwm tiv taus cua sov thiab siab, nrog rau lawv cov kev tiv thaiv corrosion, ua rau lawv muaj kev xaiv nrov hauv ntau qhov kev lag luam. Txawm hais tias koj nyob hauv kev lag luam roj thiab roj lossis lwm qhov kev lag luam uas xav tau cov kav dej kub, ASTM A106 (M) cov kav dej yog qhov kev xaiv zoo.
