Abstract

ABSTRAK ANALISIS SISA UMUR MATERIAL HP 40 MOD. MA PADA PIPA REFORMER INDUSTRI PUPUK KIMIA. Fasilitas Uji Mekanik yang berada di Pusat Teknologi dan Keselamatan Reaktor Nuklir (PTKRN) BATAN berperan penting dalam menunjang kebijakan PTKRN sebagai Pusat Unggulan Inovatif dibidang penelitian integritas struktur material. Pengalaman penelitian terkait penentuan sisa umur komponen dapat diaplikasikan tidak hanya pada reaktor nuklir namun juga pada industri strategis seperti industri pupuk kimia. Pipa reformer pada industri pupuk kimia sudah beroperasi selama empat belas tahun (14) tahun dari 67 tahun umur desain teknis jika dalam kondisi operasi normal. Untuk menjamin keselamatan operasi, analisis integritas struktur pipa reformer dengan memperhitungkan sisa umur harus dilakukan. Tujuan penelitian ini adalah melakukan perhitungan sisa umur pipa reformer dengan menggunakan pengujian creep dan metode Larson Miller Parameter (LMP). Pengujian creep dilakukan pada beban dan temperatur konstan. Dari hasil perhitungan sisa umur diperoleh sisa umur pipa reformer pada temperatur operasi 850oC dan tekanan 35-40 Bar adalah 8 tahun. Dari hasil perhitungan dapat diharapkan bahwa komponen pipa reformer masih dapat beroperasi dengan selamat sampai 8 tahun kedepan dengan syarat kondisi operasi normal Kata kunci: perhitungan sisa umur, pipa reformer, industri pupuk kimia, uji creep ABSTRACT REMAINING LIFE ASSESSMENT OF HP MOD MA REFORMER TUBE MATERIAL IN CHEMICAL FERTILIZER PLANT. The Mechanical Test Facility located at the Center for Nuclear Reactor Technology and Safety (PTKRN) plays an important role in supporting PTKRN's policy as a Center of Excellence in the field of nuclear safety including material structure integrity research. The experiences of PTKRN in aging management of research reactor with the purpose for determining the remaining life of components can be applied not only in nuclear reactors but also to strategic industries such as the chemical fertilizer industry. Reformers tube in the chemical fertilizer industry have been operating for fourteen years (14) years from the technical design age of 11.5 years under normal operating conditions. Its life already extends for 2.5 years. Therefore, remaining life of the reformer tube needs to be assessed for ensuring the safety of operation. The purpose of this study is to calculate the remaining life of the reformer tube using creep testing and the Larson Miller Parameter (LMP) method. Creep testing is carried out at a constant load and temperature. From the calculation is obtained the remaining life of the reformer tube at operating temperature of 850oC and a pressure of 35-40 Bar is 8 years. From the results can be expected that the reformer tube components can still operate safely for the next 8 years on condition that the operating conditions are normal Keywords: remaining life assessment, reformer tube, chemical fertilizer plant, creep test.
