4. Qhov ntev:

 

- Flange qhov ntev, nrog rau sab nraud, lub voj voog txoj kab uas hla, lub qhov taub ntawm lub qhov taub, thiab flange thickness, tau teev tseg raws li ASME B16.5 lossis lwm yam qauv.

- Qhov ntau thiab tsawg feem ntau yog li ntawm 1/2 nti mus rau 24 ntiv tes hauv cov yeeb nkab nominal, nrog rau qhov loj dua muaj rau cov ntawv thov tshwj xeeb.

 

5. Cov Qauv thiab Kev Ntsuas:

 

- ASTM B151 qhia txog cov kev cai rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov ntev, kev kam rau siab, thiab kev sim cov txheej txheem rau tooj liab alloy flanges.

- Flanges tsim nyob rau hauv kev ua raws li ASTM B151 tau dhau los ua ntau yam kev tswj xyuas zoo, suav nrog kev tshuaj xyuas tshuaj, kev ntsuas tensile, kuaj hardness, thiab tsis muaj kev puas tsuaj, kom ua tau raws li cov qauv teev tseg.

 

6.Application ntawm ASTM B151 Copper Alloy Flanges

 

ASTM B151 Copper Alloy Flanges pom dav siv nyob rau hauv ntau yam lag luam, feem ntau nyob rau hauv marine thiab seawater ib puag ncig vim lawv tshwj xeeb corrosion kuj thiab txhua yam khoom. Nov yog qee qhov kev siv ntau:
