La tubería de acero LSAW (la soldadura de arco sumergida longitudinalmente abreviada como LSAW) es un término de expresión profesional para la tubería de acero soldada de arco sumergido de la costura recta. Tuberías producidas por soldadura por arco sumergida y diámetro expandido. La tubería de acero LSAW tiene una amplia gama de especificaciones terminadas del producto, y la soldadura tiene una buena resistencia, plasticidad, uniformidad y compacidad, y tiene las ventajas del diámetro de la tubería grande, el espesor de la pared de la tubería, la resistencia a la alta presión, la resistencia a la baja temperatura y la fuerte resistencia a la corrosión. En la construcción de tuberías de petróleo y gas de alta calidad de alta resistencia, de alta calidad, la mayoría de las tuberías de acero requeridas son tuberías soldadas de arco sumergidas de arco de arco retroiledadas de paredes gruesas de gran tamaño. De acuerdo con las normas API, en oleoductos de gran escala y gas, al pasar a través de las áreas de Clase 1 y Clase 2, como regiones alpinas, lechos de mar y áreas urbanas densamente pobladas, LSAW Pipe es el único tipo de tubería aplicable designado.
