山东大鼎钢管厂The steel pipe is divided into seamless steel pipe and welded steel pipe. Seamless steel tube production process is to put solid billet or ingot into hollow capillary tube, and then rolled to the required size of steel tube. Different perforation methods and tube rolling methods have formed different  The production process of welded steel pipe into tube shape, and then weld the gap into steel pipe. Because of the different forming and welding methods, different welding pipe production methods have been formed.

刀具除锈：主要用于钢丝刷等工具磨削钢表面。可去除疏松或凸起的氧化皮、锈蚀、焊接渣等。手工工具除锈可以达到Sa水平，电动工具除锈可以达到Sa水平，如果钢表面粘附有固体氧化皮，工具除锈可以达到Sa水平。拆除效果不理想，不能满足建筑施工对保温防腐施工线的要求。

山东大鼎钢管厂Hot rolled coil is the raw material of cold drawn steel pipe. After pickling, remove the oxide scale, the product is rolled into coil. Cold work hardening caused by continuous cold deformation improves the strength轧辊可作为热浸镀锌设备的原材料，因为退火生产线配有退火生产线。轧制重量一般为吨，线圈内径为冷加工硬化和轧制应通过连续退火或钟罩炉退火来，以达到相应标准中规定的机械性能
