Abstract RIMA 625, or 62-50, is a consumable or solid wire for tungsten inert gas (TIG), metal inert gas (MIG), and submerged arc welding (SAW). The consumable is used for matching the nickel-base alloy 625 or N06625 (see Alloy Digest Ni-121, February 1967) with typical composition Ni-20%Cr-9%Mo-3.5%Nb. The product is also used as an overmatched product with respect to corrosion resistance for alloys 825, G, G3, Alloy 28, 904L and the 6% Mo group of materials. This datasheet provides information on composition, hardness, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as machining and joining. Filing Code: Ni-599. Producer or source: Metrode Products Ltd.

One of the main components of the manufacture of steel pipe is in the form of plate steel sheet, slab or hot roll coil, which of these materials may be made for various types of pipes, among others, seamless, Electric Wire Resistance, Spiral and Longitudinal pipes.The main material used welding steel pipe is a steel plate or hot roll coil. Material procurement dependence becomes an obstacle for welding steel pipe mill, which at this moment in our country's steel mills have not been able to produce material of diameter of 24 "steel pipe used primarily in the oil and gas sector.In this research, the analysis of welded steel pipe manufacture using local plate material consisting of two sections then welded with GMAW and SMAW welding type, where the manufacture of welded steel pipe with dimensions Ø 28 "x 8.7 mm x 12.000 mm is done using the LSAW (Longitudinal Sub Merged Arc Welding) method. Mechanical testing and inspection conducted in accordance with ASTM A139.Based on the analysis of the results of testing and inspection, it can be concluded that the method of manufacture of welded steel pipes using dual seam weld longitudinal submerged arc welding compliant as required in the standard ASTM A139.Keywords : steel pipe, dual seam weld, ASTM A139Abstrak Salah satu komponen utama dari pembuatan pipa baja adalah baja berupa plat lembaran, slab atau hot roll coil, dimana dari bahan ini dapat dibuat berbagai jenis pipa antara lain pipa seamless, pipa Electric Wire Resistance, pipa Spiral, dan Pipa Longitudinal.Material utama pipa baja las yang digunakan adalah plat baja atau hot roll coil. Ketergantungan pengadaan material menjadi kendala bagi pabrik pipa baja las, dimana pada saat ini pabrik baja di negara kita belum mampu memproduksi bahan pipa baja berdiameter lebih dari 24” terutama digunakan pada sektor minyak dan gas.Pada penelitian ini dilakukan analisis pembuatan pipa baja las dengan menggunakan bahan plat lokal yang terdiri dari dua bagian kemudian di las dengan jenis las GMAW dan SMAW, dimana pembuatan pipa baja las dengan dimensi Ø 28” x 8,7 mm x 12.000 mm dilakukan menggunakan metoda LSAW (Longitudinal Sub Merged Arc Welding). Teknik pengujian dan pemeriksaan dilakukan dengan mengacu pada standar ASTM A139.Berdasarkan analisis hasil pengujian dan pemeriksaan, dapat di simpulkan bahwa metode pembuatan pipa baja las menggunakan metode dual seam weld longitudinal submerged arc welding memenuhi persyaratan standar sebagaimana yang dipersyaratkan pada standar ASTM A139.Kata kunci: pipa baja, las dua bagian, ASTM A139
