Spesifikasi ASTM A36 mencakup produk baja karbon termasuk pipa, yang dapat digunakan dalam pembangunan jembatan dan bangunan. Pipa seamless baja karbon ASTM A36 yang ditentukan juga dapat digunakan untuk keperluan struktural adat. Spesifikasi panggilan untuk kinerja analisis panas pada produk. Analisis panas dilakukan pada pipa baja ASTM A36 Jadwal 40 untuk menentukan komposisi kimia yang diperlukan.
Unsur -unsur yang ditambahkan dalam paduan pipa ASTM A36 termasuk mangan, karbon, fosfor, silikon, sulfur, dan tembaga. Seiring dengan analisis panas, pipa seamless ASTM A36 dievaluasi menggunakan uji tegangan. Beberapa parameter termasuk produk tarik dan luluh produk selain sifat perpanjangannya diperiksa. Properti ini harus sesuai dengan sifat tarik yang diharapkan. Menjadi tingkat struktural, pipa air astm karbon ASTM A36 Pipa air menunjukkan sifat las yang baik, dan mudah dilapisi dengan penggunaan salah satu teknik berikut - pengelasan busur logam gas yaitu GMAW, atau pengelasan mig, pengelasan busur logam terlindung yaitu Smaw, atau tongkat pengelasan, serta pengelasan okyacetylene. Tabung baja karbon ASTM A36 dapat dikeraskan atau dikarsali menggunakan salah satu teknik konvensional yang digunakan pada AISI 1018 kelas baja paduan.

| Short Description | Spiral welded pipe is manufactured from steel coil. The coil is unwound and then welded while it is being turned into the shape of the pipe. Changing the angle of the spiral and the thickness of the coil is all that is needed to change from one pipe size to another. The two sides of the double submerged arc weld penetrate the full thickness of the steel to ensure the strength of the finished pipe. Full scale tests have shown that high quality spiral welded pipe is as strong as API pipe. The strength and flexible manufacturing of spiral welded pipe make it the product of choice for a variety of applications. |
