PENGARUH QUENCHING SETELAH PENGELASAN TERHADAP KOROSI DI BAWAH INSULASI MEDIA…
Corrosion in low-carbon steel is a significant issue in the industrial world, particularly in the oil, gas, refining, and chemical industries, as it leads to substantial financial losses. The total losses experienced by companies in Indonesia are estimated to reach 2-5% of the country's GDP. Corrosion arising from insulation damage, known as Corrosion Under Insulation (CUI), is challenging to d…

KARAKTERISASI MEMBRAN POLYVINYLIDENE FLUORIDE DENGAN PENAMBAHAN TIMAH DIOXIDE…
A membrane is a thin layer that functions as a selective barrier between two phases, allowing certain phases/components to penetrate more quickly than other phases/components. The current that enters the membrane is the charging current, the phase that passes through the membrane is called permeable while the phase that does not enter the membrane is called retention. In this study, filter memb…

CORROSION UNDER INSULATION MEDIA AIR LAUT DAN AIR RAWA PADA PENGELASAN BAJA A…
In general, corrosion damages material surfaces due to the presence of chemical compounds, especially in metals undergoing electrochemical reactions. The estimated impact of this damage is approximately 1.5% of the Gross National Product. Currently, the application of insulation as a preventive measure against corrosion in the industrial sector has significantly increased. Corrosion beneath ins…

Korosi adalah penurunan kualitas logam yang disebabkan oleh reaksi oksidasi dan reduksi dengan lingkungan. Korosi di bawah isolasi adalah korosi eksternal dari pipa dan bejana baja tahan karat yang disebabkan oleh penetrasi air di bawah lapisan luar atau isolasi. Korosi dapat terbentuk pada permukaan pelat maupun area sambungan las yang dipengaruhi oleh media korosi dan proses pengelasan. Penel…

EFEK POST WELD HEAT TREATMENT PADA SAMBUNGAN LAS TAK SEJENIS SMAW AUSTENITIC …
One way to improve weld quality including phase inhomogeneity and mechanical properties is Post weld heat treatment (PWHT). This study aims to determine the effect of Post Weld Heat Treatment parameters on weld quality in welding two different types of steel namely AISI 304 and AISI 1037. The welding method chosen is Shielded Metal Arc Welding (SMAW). Heat treatment is applied to specimens with…

This study analyzes the effect of setting variations in welding current on the hardness and corrosion rate of iron plate. The contribution of this research is to know the results of hardness testing with or without treatment and the corrosion rate with immersion times of 6, 12 and 18 hours. To validate the results, the plate model was treated with no treatment while the corrosion rate of the pl…
