Diferenças entre as normas JB/T4701-2000 e HG/T20592: uma é uma norma da indústria mecânica, enquanto a outra é uma norma da indústria química. Quais são exatamente as diferenças?

Quanto a essa questão, por um lado temos as flanges de solda plana do tipo A (atualizadas conforme NB/T47021-212) e, por outro, os padrões para flanges de tubulação; basicamente, não há como compará-los.
