La tubería de acero soldada con resistencia eléctrica de costura recta de alta frecuencia (tubería de acero erw) es una bobina laminada en caliente después de la formación de la máquina, el uso del efecto de piel de corriente de alta frecuencia y los efectos de proximidad, el borde del tubo se calienta y se derrite, el rodillo de compresión bajo soldadura a presión para lograr la producción.
La tubería de acero de soldadura por resistencia de alta frecuencia, la tubería de soldadura y el proceso de soldadura normal no son lo mismo, la soldadura está hecha del metal base fundido del cuerpo, la resistencia mecánica es mejor que la tubería general. Apariencia suave, alta precisión, soldadura de bajo costo alta y pequeña, revestimiento anticorrosión 3PE favorable. Existen diferencias significativas en los métodos de soldadura entre la tubería soldada por alta frecuencia y la tubería soldada por arco sumergido. Como la soldadura se realiza instantáneamente a alta velocidad, la dificultad de asegurar la calidad de la soldadura es mucho mayor que la de la soldadura por arco sumergido.
Carcasa ERW
Estándar: API SPEC 5CT
Aplicación: La carcasa sirve como pared de pozo
