Abstract

Pipe connecting system that is connected with a valve using a flange connection. This aims to make it easier to install or disconnect when needed. This connection system includes pipe connections to fittings, valves, equipment, or other parts which are separate parts of the piping system. The analysis of the flange strength on the 4 inch ball valve ANSI 300 aims to determine and ensure that the flange has strength and is safe at the time of tide due to the influence of the torque bolt. In addition, to ensure the connection does not leak when the fluid is passed. The main combination between internal, axial pressure and thermal loading needs to be considered. Flange strength analysis using Finite Element Analysis (FEA) method with use of Solid works software. The analysis of flange strength uses the method of "Flange as weakest part philosophy", namely the full rating used when the value of a certain pressure-temperature on ASME B16.5 is taken for the Maximum Allowable Working Pressure (MAWP) in the piping system. From the results of the FEA analysis, it was found that the flange on the 4 inch ANSI 300 ball valve meets the requirements according to MAWP at different temperatures and pressures. The value of the safety factor also shows that the flange is safe during the piping work process.

Abstract

The clay crushing machine will print bricks to soften or thin the soil mixture after immersion in a pond. This machine can increase brick farmers' time efficiency and production in micro, small and medium enterprises (UMKM). The method used to soften or thin the dough is using a screw conveyor as a soil pusher and a crushing knife as a soil crusher. The results of processing clay using a crushing machine are smooth and even. The trial results that have been printed, then dried and burned, produce solid and good-quality bricks. This machine can pulverize quickly compared to traditional processors, and this machine can cut processing time by two days compared to the manual method. A crushing machine with a capacity of 3 kg, a trial process was carried out using four buckets of clay, then the capacity of the soil crushing process was around 3 kg per 5 seconds, with a capacity of 300 cm3/second. The calculation of the potential production potential of this crushing machine in 1 working day, which is 8 hours, is capable of processing clay that is ready for production as raw material for bricks up to 8640 bricks/per day
