精密管-售后完善

Some distributors seize this point and work with downstream end users to inform seamless steel mills of their respective requirements for precision steel pipes and then send the products directly to end users for use. This method is helpful for dealers to firmly grasp the needs of the downstream end-users. It can not only transport precision steel pipes from the precision steel pipe mill to the downstream end-users, but also ensure that the end-users can use seamless steel pipe products more quickly. In this way, the efficiency of the precision steel pipe is improved,of pure trade has become increasingly limited, to expand the precision steel pipe processing business, so that they can not be replaced in order to survive.液压和气动缸筒用精密内径无缝钢管（GB8713-88）是制造液压和气动缸筒用的具有精密内径尺寸的冷拔或冷轧精密无缝钢管。供暖采用聚氨酯保温管那是一种趋势 直埋式外压波纹补偿外壳及导向套筒保护下实现自由伸缩补偿冷拔或冷轧精密无缝钢管（GB3639-83）是用于机械结构、液压设备的尺寸精度高和表面光洁度好的冷拔或冷轧精密无缝钢管。选用精密无缝钢管制造机械结构或液压设备等，可以大大节约机械加工工时，提高材料利用率，同时有利于提高产品质量。精密钢管的种类很多。许多精密钢管需要在下游用户使用之前进行加工。

山东大鼎金属材料有限公司The main characteristics of precision seamless steel pipe in precision steel pipe mill are: high precision, high inner and outer wall finish, no oxide layer after heat treatment, high inner wall cleanliness, high pressure bearing, cold bending deformation, flattening, no crack. It can be used for all kinds of complex deformation and machining. Steel tube color: bright white medium, high metallic luster. Precision seamless steel pipe process: high quality carbon steel, finish rolling, non-oxidizing bright heat treatment state, non-destructive testing, steel pipe inner wall with special equipment cleaning, high pressure flushing, rust-proof oil coated on the steel pipe, used for rust prevention. When installing, two end covers are used for dust prevention.山东大鼎钢管厂石油裂化用无缝钢管（GB9948-88）是适用于石油精炼厂的炉管、热交换器和管道无缝钢管。7.地质钻探用钢管（YB235-70）是供地质部门进行岩心钻探使用的钢管。8.金刚石岩芯钻探用无缝钢管（GB3423-82）是用于金刚石岩芯钻探的钻杆、岩心杆、套管的无缝钢管。

The products can be rough castings or cold parts. The company has six production lines of large and medium-sized cold-drawn precision seamless steel pipe and cold-rolled precision seamless steel pipe mill, one roller hearth heat treatment furnace and three sets of ordinary cold-drawn seamless steel pipe mills.
