ASTM A210 yog tus qauv tshwj xeeb rau seamless nruab nrab-carbon steel boiler thiab superheater raj, feem ntau siv rau hauv kev lag luam thiab kev siv hluav taws xob. Nyob rau hauv tsab xov xwm no, peb yuav tham txog cov khoom, specification, tshuaj muaj pes tsawg leeg, mechanical zog, steel qib, thiab daim ntawv thov ntawm ASTM A210 carbon steel kav.

Khoom siv

A210 carbon steel kav yog tsim los ntawm kev sib xyaw ntawm hlau thiab carbon, nrog me me ntawm manganese, silicon, thiab phosphorus. Cov ntsiab lus carbon nyob rau hauv hom hlau no txawv ntawm 0.27 feem pua rau 0.35 feem pua , ua rau nws yog cov hlau nruab nrab-carbon.

Specification

ASTM A210 carbon steel yeeb nkab specification npog seamless nruab nrab-carbon steel boiler thiab superheater raj. Cov raj no yog tsim los siv rau hauv boilers, flues, thiab superheater raj. Cov kev qhia tshwj xeeb suav nrog ntau qib ntawm cov kav dej carbon steel, xws li A1, C, thiab SA-1.

Qib Steel

A210 carbon steel kav tuaj ntau qib, suav nrog A1, C, thiab SA-1. Txhua qib muaj cov khoom sib txawv thiab siv rau kev siv sib txawv. Qib A1 yog qhov tsim nyog rau cov ntawv thov kub txog li 760 degree (1400 degree F), thaum qib C yog tsim los rau kev siv siab.

Daim ntawv thov

A210 carbon steel kav feem ntau siv rau hauv kev lag luam thiab kev siv hluav taws xob tsim hluav taws xob. Cov kav dej no yog siv los thauj cov dej kub, chav dej, thiab lwm yam dej hauv boilers, flues, thiab superheater raj. Lawv kuj tau siv rau hauv cov khoom siv hluav taws xob, cov condensers, thiab lwm yam kev siv zoo sib xws.
