The popularization and application of high-precision pipes saves steel, improves processing efficiency and saves energy. The so-called high-precision cold-drawn pipe refers to the internal and external diameter precision (tolerance range) is strict, good surface finish, good roundness, uniform wall thickness of cold-drawn pipe. The main technical indexes of the high precision cold drawn tube produced by this technology reach the expected goal. Details are shown in the following table: the main technical indicators and the standard control table items have actually reached the GB8713-88 ISO4394 internal diameter tolerance H8 H9 H8 H8 H8 H8 H8 H8 H8 H8 H9 H9 H10 straightness 0.3 > 0.5/1000B wall thickness deviation roundness汽车半轴套管用无缝钢管（GB3088-82）是制造汽车半轴套管及驱动桥桥壳轴管用的优质碳素结构钢和合金结构钢热轧无缝钢管。德威花园城一期占地约 这是它的柴油机用高压油管（GB3093-86）是制造柴油机喷射系统高压管用的冷拔无缝钢管。精密管或冷轧精密无缝管(GB3639-2000)是机械结构和液压设备用尺寸精度高、表面光洁度好的冷拔或冷轧精密无缝管。高精度精密管是一种新型的高技术节能产品。

Following the decline in crude steel production in the first ten days of this month, crude steel production rose again in the first ten days of this month. Inventories of heat preservation and anticorrosion pipe manufacturers and factories also declined. The production situation of secondary or steel plants is not clear. At present, as raw material prices continue to fall, consumer enterprises still have profit margins; coupled with financial pressure, most steel mills need to maintain operation in order to continue to obtain savings; therefore, steel mills still adhere to a higher start-up rate; Anshan region, for example, as of this month, Tangshan blast furnace start-up rate is about.0%, high production capacity application rate. Up to.0%, the rate of increase was normal.山东大鼎钢管厂、山东大鼎金属材料有限公司
