Abstract

Kegiatan pengangkatan dan pemindahan beban di sektor panas bumi memerlukan perangkat lifting gear, termasuk wire rope sling, sebagai elemen vital dalam menjamin keselamatan kerja. Penurunan kualitas wire rope seiring penggunaan menjadi perhatian utama karena berpotensi menimbulkan kecelakaan kerja. Penelitian ini bertujuan untuk mengevaluasi kondisi wire rope sling melalui metode inspeksi visual dan uji penetrant sesuai standar ASME Section V. Metodologi meliputi observasi lapangan, persiapan spesimen, serta pengujian penetrant dengan cairan kimia SKL-SP1, SKD-52 dan SKC-5 buatan Magnaflux. Pemeriksaan dilakukan terhadap wire rope sling berdiameter 18,4 mm dengan konstruksi 6x36 WS IWRC dan sertifikasi sesuai standar manufaktur. Hasil inspeksi menunjukkan tidak ditemukan indikasi cacat permukaan seperti crack atau corrosion pits yang signifikan. Uji penetrant memperkuat hasil visual dengan tidak adanya indikasi linier relevan (>1,5 mm) maupun rounded relevan (>5 mm), yang mengindikasikan wire rope layak digunakan dalam jangka waktu operasional sesuai regulasi perusahaan. Hasil ini menegaskan bahwa kombinasi inspeksi visual dan penetrant test efektif dalam memastikan kelayakan wire rope sling. Penelitian ini merekomendasikan inspeksi berkala setiap enam bulan dengan pencatatan hasil sebagai referensi historis. Temuan ini dapat dijadikan acuan untuk prosedur inspeksi di industri sejenis guna meningkatkan keandalan dan keselamatan operasional alat angkat

Abstract

Cutting metals, such as carbon steel, is a stage of engineering and repairing casing pipes or casings made of carbon steel material in accordance with the cut marks that have been set in the marking process. For pipe cutting or welding preparation tasks related to maintenance or new construction, there are basically two different methods used. The first is hot cutting by hand grinding, and the second is a portable unit popularly known as cold cutting that produces weld-ready surfaces. Low Clearance Split Frame (LCSF) is a portable unit used as cold cutting that produces weld-ready surfaces, where cutting occurs due to an air pressure reaction from the water compressor with a portable unit and carbon steel. Low Clearance Split Frame (LCSF) is used manually without going through a heating process, where the unit is mounted around the outer diameter of the case in parallel or tucked into an open-end pipe, and is designed to apply square and precision cuts. The unit requires little maintenance in the form of lubrication, fast operating time and no hot work. For the cutting work here, the material used is a carbon steel casing. In the cutting work of carbon steel casings here, Low Clearance Split Frame (LCSF) is used, where the obstacles found are found in the cutting blade or called the parting blade that is dull, so that sometimes the results of the cutting work become inefficient, such as the surface of the casing that is not smooth and the time to finish the work. This causes the process of sharpening or replacing the parting blade, until the machine can operate optimally. As of this writing, it has been designed for cutting carbon steel casings using Low Clearance Split Frame (LCSF) which aims to produce straight, flat and smooth cuts of carbon steel casings and can produce a 20" outer diameter casing cut with a cutting time of < 60 minutes, a cutting speed on a surface of 60 ft/min (30 cm/sec), and a cut tolerance of + 3 mm
