冷拔钢管的国家标准;GB/T699-2008,冷拔钢管的国家标准;GB/T3639-2008,另外可能也还有应用GB/T8162-2008结构用冷拔钢管的。 冷拔钢管广泛用于汽车、摩托车、电动车、石化、电力、船只、航天、轴承、气动元件、中低压锅炉冷拔无缝钢管等范畴,也可适用于钢筋套筒、轴承、液压、机械钣金加工等领域!

National Standards for Cold-drawn Steel Tubes; GB/T699-2008, National Standards for Cold-drawn Steel Tubes; GB/T3639-2008, in addition, there may also be cold-drawn steel tubes for structures using GB/T8162-2008. Cold-drawn steel pipes are widely used in automobiles, motorcycles, electric vehicles, petrochemical, electric power, ships, aerospace, bearings, pneumatic components, low and medium pressure boilers, cold-drawn seamless steel pipes and other fields, but also applicable to steel sleeves, bearings, hydraulic, mechanical processing and other fields! 折叠编辑本段生产流程

冷拔钢管的生产流程和普通的冷拔无缝钢管一样,就是多了道最后酸洗冷轧的程序。

The production process of cold-drawn steel pipe is the same as that of ordinary seamless pipe, that is, there are many final pickling and cold rolling procedures.

钢管区别

Steel tube difference

1、无缝钢管主要特点是无焊接缝,可承受较大的压力。产品可以是很粗糙的铸态或冷拨件。

1. The main characteristics of seamless steel pipe are that it has no welding seam and can withstand large pressure. Products can be very rough as-cast or cold-dialed parts.

2、冷拔冷拔钢管是近几年出现的产品,主要是内孔、外壁尺寸有严格的公差及粗糙度。

2. Cold-drawn steel pipe is a product that has appeared in recent years. It mainly has strict tolerance and roughness for inner hole and outer wall dimensions.
