Perbedaan Pipa Seamless Dan Pipa Welded

Adapun untuk proses diatas istilahnya dari Electric Resistance Welding, Electro Fusion Welding, High-Frequency Welding untuk pipa besi yang menggunakan las longitudinal. Lalu untuk pipa dengan las spiral, teknik las menggunakan Submerged Arc Welding bisa dibilang lebih banyak diminati.

Jika pipa welded memiliki sambungan las dibatangnya, jutru pipa seamless adalah kebalikannya. Pipa seamless bisa dibilang merupakan sebuah pipa besi yang tidak memiliki sambungan. Seperti halnya pipa welded yang memiliki berbagai macam metode pengelasan, pipa seamless juga memiliki banyak metode produksi. Salah satu metode yang biasa digunakan adalah Mandreel Mill Process, yang tidak jauh berbeda dengan proses Mannesmann Plug Mill (Hot Rotaru Piercing).



Metode lain yang digunakan dalam pembuatan pipa seamless adalah Push-Bench Process dan Extruction Process. Untuk prosesnya terbilang cukup rumit daripada pipa welded. Billet baja yang telah dipanaskan akan dipanaskan melalui proses piercing yang kemudian dimasukkan ke dalam mill.  Selanjutnya billet akan melalui proses penggulungan dan peregangan dengan tujuan untuk menyesuaikan ukuran panjang,  diameter, ketebalan dan juga dinding pada pipa seamless.

Fungsi Pipa Seamless vs Pipa Welded

Selanjutnya apakah untuk fungsi dari pipa seamless dan pipa welded juga berbeda? Fungsi kedua pipa tersebut sudah pasti berbeda karena telah disesuaikan dengan kebutuhan pengguna. Pipa welded umumnya lebih rentan dibandingkan pipa seamless karena sambungan las yang ada pada bagian batangnya. Sementara untuk pipa seamless tidak memiliki sambungan atau cacat struktural jauh lebih kuat.
