ASME SA192 Seamless Boiler Pipe rau cov khoom siv hluav taws xob sib txawv Specification
Cov lus qhia no suav nrog cov qauv tshwj xeeb rau qhov tsawg kawg nkaus-phab ntsa-thickness, seamless carbon steel boiler thiab superheater raj rau kev pabcuam siab. Cov hlau yuav tsum ua raws li qhov xav tau ntawm cov tshuaj muaj pes tsawg leeg rau carbon, manganese, phosphorus, sulfur, thiab silicon. Cov raj yuav tsum muaj tus lej hardness tsis pub tshaj tus nqi tshwj xeeb. Cov kev ntsuam xyuas hauv qab no yuav tsum tau ua, xws li: kev ntsuam xyuas flattening; flaring xeem; xeem hardness; thiab kuaj hydrostatic.
1.Qhov kev qhia tshwj xeeb no suav nrog qhov tsawg kawg nkaus-phab ntsa-thickness, seamless carbon steel boiler thiab superheater raj rau kev pabcuam siab.
2.SA192 Boiler Tubes qhov ntau thiab tsawg thiab thicknesses feem ntau muab rau qhov tshwj xeeb no yog 1/2 in. to 7 in. [12.7 to 177.8 mm] sab nraud txoj kab uas hla thiab 0.085 mus rau 1.000 in. [2.2 mus rau 25.4 mm], suav nrog, yam tsawg kawg nkaus phab ntsa thickness. Tubing muaj lwm qhov ntev yuav raug muab tso rau, yog tias cov raj no ua tau raws li tag nrho lwm cov kev cai ntawm qhov kev qhia no.
3.Mechanical khoom yuav tsum tsis txhob siv rau tubing me dua 1/8 in. [3.2 mm] hauv txoj kab uas hla los yog 0.015 in. [0.4 mm] thickness.
