ASME SA178 and ASTM A178 Boiler Tubes exhibit features such as low carbon steel (C=0.18 Max) and are Eddy Current Tested ASTM A178M Superheater Tubes with a minimum wall thickness.
2023The main standards for precision hydraulic steel tubes are as follows:China: GB/T 3639,Germany: DIN 2391, DIN 2393, DIN 2445,European Union: EN 10305,Germany: DIN 1630, DIN 1629,United States: ASTM A519, Japan: JIS G3445
2023Precision bright tubes are high-precision, high-smoothness steel tubes typically manufactured through cold rolling or cold drawing processes. Their smooth surface and precise dimensions make them widely used in hydraulic systems
2023DIN 1630 NBK Hydraulic Tube - Metric Sizes:DIN 1630 NBK (normalized) seamless steel tubes are typically used for hydraulic and pneumatic power systems.
2023Hydraulic steel tubes are available in various sizes and dimensions to meet different application requirements. The OD and WT values are typically specified in millimeters for metric sizes and inches for imperial sizes.
