Defects on the inner surface of seamless steel pipes how inner tube seamless capillary steel pipe

Compared with ordinary cold drawn steel pipe, cold drawn precision seamless steel pipe production increases the hot-rolled capillary pickling re-inspection process, mainly to ensure that there are no defects such as folding and crack on the outer surface of the capillary tube, and the inner surface is excluded from folding and severely scribed. Tubes with defects such as pockmarks.Seamless Steel Tube Capillary Extension ProcessOct 05, 2018When the seamless steel tube is tempered at 650 °C, its impact toughness value is the lowest, that is, the temper brittle zone, so it is not suitable to temper in this temperature range. It should be noted that the Wuxi seamless steel pipe is quenched below 1100 ° C, and the medium grain of 4-6 grade is obtained, and there is no secondary hardening peak.Seamless pipe defects and causes - Sunny Steel Abscission. Characteristics of defects in the steel pipe inner surface of the vertical distribution was Straight within the fold. Characteristics of defects in the steel pipe inner surface of the vertical Wall contractions. Characteristics of defects steel pipe horizontal thinnest section is surface Within the rolling scars. Characteristics of defects inner surface of steel pipe is vertical to nail Rolling fold. Characteristics of defects located on the partial or total length of the inner surface Double seam fold. Characteristics of defects cracks in the steel pipe surface are sometimes
