“…Sambungan pompa ke pipa hisap dan pipa keluar menggunakan sambungan flange. Jenis sambungan flange baut adalah jenis sambungan yang paling populer untuk di gunakan di tangki bertekanan dan perpipaan, karena mudahnya proses bongkar pasang [4]. Sambungan di sistem perpipaan akan menggunakan sambungan ulir.…”

Abstrak Lab fluida difungsikan sebagai tempat pengambilan data untuk proses pembelajaran maupun penelitian tentang fluida. Kondisi saat ini belum adanya lab fluida di universitas mercubuana keranggan yang digunakan sebagai objek pengambilan data untuk penelitian. Rancang bangun mini lab fluida dibutuhkan untuk menunjang kegiatan pengambilan data. Studi literatur untuk perancangan menggunakan buku, jurnal, dan internet. Diskusi dilakukan dengan dosen pembimbing dan mahasiswa yang akan melakukan penelitian pada mini lab fluida.Berdasarkan perhitungan beban, meja menggunakan besi hollow 60x40x4. Pompa yang digunakan adalah pompa sentrifugal dengan debit 9 m3/h dan total head 5 m. Pipa yang digunakan adalah pipa galvanis 1 1/2 inch. Valve dengan type ball valve, dan tangki dengan kapasitas 300 L. Pengaturan speed pompa menggunakan VSD (Variabel Speed Drive) dan untuk mengatur voltage menggunakan AVR (Analog Voltage Regulator). Kata kunci : Lab fluida, perpipaan, pengujian Abstract The fluid lab is functioned as a place for retrieving data in order to learn the process and leading research of fluid. At this time, the fluid lab is not yet available in Mercubuana University Kranggan, which is necessary utilized for research. Design and development of mini lab of fluid is necessary accomplished to support activity of collecting data. The references are used in the study of literature for design this research object, such as book, journal and other internet sources. In the process, there are some discussion between preceptor lecturer and the student whose charge in research of mini fluid lab. Based on the calculation of weight forces, the table uses hollow iron in dimension 60x40x4. By using the sentrifugal pump, which has flow capacity of 9 m3/h and total head of 5 m. Also, the galvanic pipe with dimension 1 ½ inch. In addition, other specifications are valve with ball type and the tank in capacity of 300 L. For setting the flow speed of pump is by using VSD (Variable Speed Drive) and AVR (Analog Voltage Regulator) as component for voltage adjusment.

“…Experimental tests of the process of tightening multi-bolted connections are carried out mainly for connections showing geometric symmetry or load symmetry. These studies include tightening in one pass [53][54][55] and in several passes [56][57][58]. In this study, these two types of tightening were also used.…”

In the paper, experimental studies of an asymmetric preloaded seven-bolted connection are presented. The tightening process of the connection was carried out with a wrench, monitoring the values of the bolt forces with a calibrated strain gauge measuring system. Two methods of bolt tightening were tested: in one and several passes. After all bolts were tightened, the selected bolts were removed, simulating bolt failure under the loading conditions of the connection. The influence of the method and sequence of bolt tightening on the distribution of bolt forces values after the introduction of failure states of some bolts was investigated. The results were statistically processed and presented in the form of graphs showing the distributions of normalised bolt forces values for all the considered failure cases.

“…2,3 In order to avoid or at least minimize leakages, bolted joints are assembled with a uniform bolt load distribution that involves a uniform gasket stress distribution. 4,5 However, obtaining a uniform bolt load distribution is difficult due to the elastic interaction phenomenon. [6][7][8][9] During the tightening sequence, whenever a bolt is tightened, the joint gets compressed and consequently the load in previously tightened bolts decreases, and as a consequence, the final loads at the end of the assembly process are different from the tightening loads.…”

Uniform bolt load is critical to achieve leak-free service in pressure vessel gasketed joints. In a previous work, the authors presented the tetraparametric assembly method, which enabled to obtain a uniform final load distribution in a one-pass tightening sequence. The accuracy of the method was proved by finite element analysis and experimental tests. However, the tetraparametric assembly method was only developed for one-pass tightening sequences, and in some cases more than one pass can be necessary. Furthermore, the method was only validated for a particular joint geometry. In this sense, the present work generalizes the method for two-pass tightening sequences and studies the range of application.
