SCOPE
This GENERAL NS-1™ specifies the minimum quality and inspection requirements applied to wrought Low Alloy Steel Drill Collars, covering the following types:
1. Cylindrical (slick) drill collars
2. Cylindrical (slick) drill collar pup joints
3. Drill collars with slip recess
4. Spiral drill collars
5. Spiral drill collar pup joints
范围：
本通用NS-1标准规定了适用于锻造的低合金钢钻铤的最低质量和检验要求，包括如下类型：
1.圆柱（光滑）钻铤
2.圆柱（光滑）钻铤短节
3.带卡瓦槽的钻铤
4.螺旋钻铤
5.螺旋钻铤短节
It applies to:
• All operating temperatures
• Non-SOUR rvice conditions
• All drill collar sizes
This equipment shall conform to the requirements of API Spec.7-1 (ISO 10407-1), API Spec 7-2 (ISO 10407-2) and the requirements of this NS-1™. If in conflict the requirements of this NS-1™ shall prevail.
鲷
Design verification, approval and other design related parameters are specifically excluded from this NS-1™.
适用于：
•所有操作温度
•非酸性工作环境
•所有钻铤尺寸
这些装备应该符合API Spec.7-1 (ISO 10407-1)、API Spec 7-2 (ISO 10407-2)和本NS-1标准的要求。如与本标准相抵触则执行本标准。
设计校对、审批和其他相关参数的设计不包括在本标准范围之内。
SUPPLEMENTARY REQUIREMENTS
The following requirements are supplementary to and shall be applied in conjunction with the quality subspecifications运算能力 called out in the matrix of this NS-™1 Specification.
1. WELDING
No fabrication or repair welding shall be performed.
补充要求
下列要求为补充要求，连同本NS-1规范清单列出质量子规范一并应用。
1.焊接
不进行制造焊接或修理焊接。
2. THREADED CONNECTIONS AND RECESSES
洗手拼音2.1 The thread roots of all API rotary connections NC38 and larger shall be cold rolled after final machining.
2.2 All API rotary pin connections NC38 and larger, shall be provided with a stress relief groove to API Spec. 7-2 latest revision.
2.3 All box connections NC38 and larger shall be provided with a stress relief feature which may be either external or internal (e.g. API style, Drilco style, ’bore-back’).
2.4 All stress relief features and radii of the upper shoulders of the slip and elevator recess shall be cold worked after final machining. All connections which have been cold worked shall be marked by stamping the connection with a circle enclosing the letters ’CW’ as specified in API Spec. 7-2 latest revision.
2.螺纹连接和应力槽
2.1 所有API标准的NC38及更大尺寸的旋转连接的螺纹根部在最终机械加工结束后都应进行冷滾压。
2.2 所有API标准的NC38及更大尺寸的旋转连接的外螺纹都应按照API Spec 7-2最新版提供应力释放槽。
2.3 所有API标准的NC38及更大尺寸的旋转连接的内螺纹都应在其外部或内部提供应力释放结构（如：API型、Drilco型、bore-back型）。
2.4 所有应力释放槽和吊卡瓦槽上部台肩的R处都应该在最终机械加工结束后进行冷滾压。所有进行过冷滾压的螺纹连接都应该按照API Spec7-2最新版规定在螺纹连接处模印内有“CW”字母的圆环。
2.5 All new rotary connections shall be provided with a benchmark (this does not apply to pin
connections having a stress relief groove) in accordance with the requirements of ISO 10407-2, latest revision as a minimum. The preferred form of the benchmark is an indicat
or which provides a 360°reference around the connection. This type of benchmark is superior to the API one, in that it reveals not only the extent of refacing but also how perpendicular the refaced al is to the pipe’s axis.
Note: Various manufacturers can provide the preferred 360° benchmark form. The purchar should confirm this 为什么有静电with the supplier prior to manufacture.
