Petroleum and natural gas industries - Rotary drilling equipment - Part 2 : threading and gauging of rotary shouldered thread connections

ISO 10424-2:2007 specifies requirements on rotary shouldered connections for use in petroleum and natural gas industries, including dimensional requirements on threads and thread gauges, stipulations on gauging practice, gauge specifications, as well as instruments and methods for inspection of thread connections. These connections are intended primarily for use in drill-string components.Other supplementary specifications can be agreed between interested parties for special tolerance requirements, qualification, testing, inspection and finishing.ISO 10424-2:2007 is applicable to the following preferred rotary shouldered connection designs: number (NC) style; regular (REG) style; full hole (FH) style. These are traceable to an internationally supported system of gauges and calibration.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
