The flange face is the surface area that hosts the gasket. The 6 available types of flange face are flat (FF), raised (RF), ring joint (RTJ), lap joint, male and female (M&F), tongue and groove (T&G). Flanges with different faces require … Continue reading Flange Face Types, RTJ
As a common hydrostatic test procedure, the test pressure will be taken from the piping system MAWP. Depending on the primary code applied, the test pressure can be 1.5 MAWP, or 1.3 MAWP + factors, or 1.15 MAWP… etc., Refer to What is MAWP, What is Max operation pressure, Hydrostatic test: What is the MAWP of the pressure vessel (ASME VIII) FITTING PRESSURE RATING PIPE PRESSURE RATING PIPING HYDRO-STATIC TEST COMPREHENSION Test Pressure vs MAWP (ASME VIII) Design Pressure Vs MAWP (API, ASME) MAWP is normally referred to as system maximum allowance working pressure. The fitting is small and is … Continue reading Hydrostatic test with Flange Joints (considering of Flange MAWP)
Regarding What is Orifice and its application, please refer to FLOW METER AND ORIFICE PLATE Introduction of Erosion on Piping downstream around Orifice installation area: Typical erosion in piping systems often occurs on the flow with the exclusion of turbulence, for example. Where the flow direction changes (elbow, tee) or downstream of the orifice in the pipe system. In addition, Flow is a two-phase (with solid or liquid particles) and has a higher speed of erosion. In the Orifice installation area, the Flow Orifice (FO) is used to block the flow and reduce the pressure of Steam down to allow it to become condensate, but since Steam has passed from Orifice that cannot be fully condensed in this area, the turbulence of Flow will exist.

During the 62nd session of the MEPC (11–15 July 2011), at IMO Headquarters in London, the represented Parties to MARPOL Annex VI adopted amendments to Annex VI Regulations for the prevention of air pollution from ships. Considered the first regulation to establish CO2 standards across a global sector, the Energy Efficiency Design Index (EEDI). In terms of CO2 emissions, shipping contributes to about 2.5% of the world’s emissions and the emission rate will increase by 75% in the next 15 years due to demand and growth in global trade. What is EEDI mean? The EEDI is used to calculate a … Continue reading EEDI and CO2 emission
