"Pipa penyalur merupakan salah satu media transportasi hasil produksi yang banyak digunakan di industri hingga saat ini. Integritas peralatan terutama pipa penyalur harus dijaga agar dapat beroperasi sesuai target produksi. Sebagai sarana utama dalam operasional, penyusunan program perawatan merupakan hal yang krusial. Perawatan pada pipa meliputi inspeksi, line checking, dan pembersihan Right of Way (ROW) yang dilakukan secara berkala. Pada saat kegiatan inspeksi berlangsung, terdapat beberapa permasalahan dalam menentukan integritas pada pipa penyalur, diantaranya kondisi pipa yang tertutup dengan tanah (underground, half-buried), tertutup semak, dan diatas tanah disertai dengan jarakanya yang tergolong panjang sehingga memerlukan suatu metode dalam penetapan kegiatan perawatannya. Pada praktik keinsinyuran ini, penulis akan memaparkan metode agar program perawatan pipa penyalur dapat berjalan secara efektif. Pipa penyalur yang dijadikan sebagai objek merupakan pipa yang tidak memiliki fasilitas pigging sehingga tidak memenuhi kriteria untuk dilakukan metode intelligent pigging. Strategi yang dijelaskan dalam praktik keinsinyuran ini mencakup inspeksi pada pipa yang berlokasi sebagian terkubur, daerah fittings dan pipa diatas tanah. Berdasarkan pekerjaan yang telah dilakukan dengan kombinasi LRUT dan UT konvensional, mayoritas anomali yang ditemukan berupa soil corrosion dan atmospheric corrosion yang dapat dicegah dengan aplikasi coating dengan membersihkan permukaan pipa, aplikasi proteksi katodik dan inspeksi jalur pipa penyalur secara berkala.

Pipeline are one of the production media for transportation that is widely used in industry nowadays. The integrity of pipelines must be maintained to fulfill the production targets. As the operation major equipment, preparing a maintenance program for pipeline is crucial. Pipeline maintenance includes inspections, line checking, and Right of Way (ROW) cleaning should be carried out regularly. During the inspection activity, there are several problems for determining the integrity of the pipeline, including the condition of the pipe being covered with soil (underground, half-buried), covered by bushes, and above ground accompanied by a relatively long distance so that it requires specific method in determining pipeline condition. This study will explain the pipeline maintenance methods to optimize production activity. Pipeline with no pigging facilities will be used in this study, so it will not be capable to execute in-line inspection method. The strategy described in this engineering practice includes inspection of partially buried pipes, fitting areas and above ground pipelines. Based on the work that has been carried out with LRUT and UT method, the majority of anomalies found are in the form of soil corrosion and atmospheric corrosion which can be prevented by applying coatings by cleaning the pipe surface, applying cathodic protection and periodically inspecting the distribution pipeline."

"Problems and defects of all kinds arise in the development and use of mechanical devices, electrical equipment, hydraulic systems, transportation mechanisms and the like. However, an extremely wide range of nondestructive testing (NDT) methods are available to help you examine these different problems and various defects in an assortment of materials under varying circumstances. It is imperative that you select the best method to solve a particular problem. And that requires a sufficient understanding of the basic processes involved to realize the advantages of each NDT method available.In addition to practical hints and pertinent comments for the resolution of day to day problems, this book will give you sufficient basic theory to comprehend the principles of each method so that the most appropriate can be selected and used to its fullest advantage. Typical illustrative calculations and a comprehensive bibliography are provided.This book will be particularly useful to advanced technicians involved with high level III NDT training, engineers concerned with quality control, general scientists and technologists dealing with materials problems but who are not NDT specialists, and engineering students taking a course in NDT."
