无磁钻铤是使用N1310低碳合金钢制造，该材料是经过严格的化学成分分析锻造而成。该材料经机械性能测试可以确保硬度、韧性、冲击值以及抗腐蚀性能符合标准，具有良好的低磁导率和良好的机械加工性能。　  


      无磁钻铤导磁率（磁场强度=1×105/4πNm）     

      无磁钻铤最大值：1.010　　平均值：μr ≤ 1.005　　

      无磁钻铤磁场梯度：（热点）最大值：B ≤ 0.05

 

      我公司有各种规格（Ф105  Ф121  Ф159  Ф165  Ф178）长度为9.3m的无磁钻铤，还有长度为3.5m、6.5m 、5.5m的非开挖穿越用的各种规格无磁短钻铤、无磁转换接头、无磁造斜短节、无磁非开挖定向钻头。
 Non-magnetic Drill Collar无磁钻铤 It's made from N1310 low carbonalloy-steel and forged by strict chemical analysis. By testing its mechanical properties, we can ensure the material's hardness, toughness, impact value and corrosion resistance conform to the standard. It has favorable low-permeability and machining properties. Magnetic permeability (MPS=1×105/4πNm)Max:1. 010Average Value:μr≤1. 005Field Gradient (hot spots)max: B≤0. 05We have some non-magnetic drill collars with specifications of 165, 159, 121 and 105, as well as some non-magnetic short drill collar with specification of 5. 5m, 4. 5m And 3m.All Customers (old or potential) are warmly welcome! Look forward our early and sincere cooperation.
