Aplicação da NR-13 em vasos de pressão para dióxido de carbono
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2014-12-16)
Carbon dioxide, known as CO2 gas is supplied by the firm of fertilizers with 99.5% purity at a pressure of 1,5kgf/ cm2 and temperature of 20°C (twenty degrees Celsius), where 5% of contaminants are hydrocarbon that will ...
Effects of a postweld heat treatment on a submerged arc welded ASTM A537 pressure vessel steel
(Asm International, 2001-06-01)
Postweld heat treatment (PWHT) is frequently applied to steel pressure vessels, following the requirements of the ASME code (section VIII), which establishes the parameters of the PWHT based on the thickness and chemical ...
