地质钻杆及接头 Drill Pipe and Adapter 地质钻杆及接头执行API SPEC 5DP标准，钻杆现有G105、S135钢级，均经过局部或整体热处理，机械性能完全满足标准要求；采用优质合金钢4137H、4137M等调质处理，螺纹由数控车床、成型刀具加工，表面镀铜或磷化处理，防粘扣性能良好。也可根据客户要求定制生产。 Drill pipe and adapter are in accordance with API SPEC 5DP Specifications. The steel grades are G105、S135that are after partly or overall heat treatment. The adapter part adopts thermal refining to superior alloy steel 4137Hor 4137M that’s after thread hardening treatment and phosphating to better anti-galling. It also can be produced upon customers’ requirements. 主要技术参数 Technical Specifications 钻杆直径 Drill pipe diameter 钢级 Steel grade 加厚型式 Upset type RSC 类型 Model 管子壁厚t（mm） Wall thickness 接头外径D（mm） External diameter 公接头内径dp（mm） Internal diameter of male end in mm 2-7/8 73.02 E EU NC31 9.19 104.8 54.0 X,G EU NC31 9.19 104.8 50.8 S EU NC31 9.19 111.1 41.3 3-1/2 88.90 E EU NC38 6.45 120.7 68.3 E EU NC38 9.35 127.0 68.3 X EU NC38 9.35 127.0 65.1 G EU NC38 9.35 127.0 61.9 S EU NC38 9.35 127.0 54.0 E EU NC38 11.40 127.0 65.1 X EU NC38 11.40 127.0 61.9 G EU NC38 11.40 127.0 54.0 S EU NC40 11.40 139.7 57.2 4-1/2 114.3 E EU NC50 6.88 168.3 95.3 E EU NC50 8.56 168.3 95.3 X,G EU NC50 8.56 168.3 95.3 S EU NC50 8.56 168.3 88.9 E EU NC50 10.92 168.3 92.1 X,G EU NC50 10.92 168.3 88.9 S EU NC50 10.92 168.3 76.2 E IEU NC46 8.56 158.8 82.6 X,G IEU NC46 8.56 158.8 76.2 S IEU NC46 8.56 158.8 69.9 E IEU NC46 10.92 158.8 76.2 X IEU NC46 10.92 158.8 69.9 G IEU NC46 10.92 158.8 63.5 S IEU NC46 10.92 158.8 57.2 5 127 E IEU NC50 9.19 168.3 95.3 X IEU NC50 9.19 168.3 88.9 G IEU NC50 9.19 168.3 82.6 S IEU NC50 9.19 168.3 69.9 E IEU NC50 12.70 168.3 88.9 X IEU NC50 12.70 168.3 76.2 G IEU NC50 12.70 168.3 69.9 除上述规格外，也可根据客户要求定制生产。 主要技术参数 规格 mm 钢级 杆体壁厚 mm 通径 mm 静扭能力 N.m 抗拉能力 T 推荐钻头 规格/mm 推荐钻机 能力/N.m Φ42 R780 6.8 Φ16 2400 10 Φ60-Φ65 ≤750 Φ50 R780 6.5 Φ16 3500 12 Φ65-Φ75 ≤1200 Φ63.5 R780 7 Φ20 11000 20 Φ85-Φ94 ≤3200 Φ73 R780 7 Φ23 14000 50 Φ94-Φ113 ≤4000 G105 7 Φ23 23000 100 Φ94-Φ153 ≤6000 Φ89 R780 8 Φ40 25000 65 Φ113-Φ153 ≤10000 G105
