Di proyek konstruksi perpipaan tentu tidak asing dengan istilah nominal pipe size maupun schedule. Yap! NPS dan SCH adalah metode standar untuk menentukan ukuran dan ketebalan pipa yang secara umum digunakan di process plant.

Dimensi pipa yang mencakup ukuran dan schedule ini merupakan salah satu pengetahuan yang wajib dimiliki utamanya ketika Anda bekerja di proyek konstruksi dan piping. Artikel ini akan mengulas semuanya mengenai apa itu Nominal Pipe Size, Diameter Nominal, schedule pipa beserta tabelnya.
