Overview
SIST EN ISO 4231:2017 specifies the standardized dimensions for hand- and machine-operated circular screwing dies designed for producing parallel pipe threads in the G series, in accordance with ISO 228-1. This European and international standard acts as a supplement to ISO 2568 and ISO 4230, ensuring dimensional compatibility and interchangeability.
The standard defines key dimensions such as diameter, thickness, and fixing sizes of screwing dies, which align with the specifications of ISO 2568 to allow hand-operated dies to be used with die stocks defined therein. Developed by ISO/TC 29 "Small tools", this third edition (2016) supersedes EN 24231:1989 and facilitates harmonized manufacturing and tool selection for pipe thread production across industries.
Key Topics
Scope and Application
SIST EN ISO 4231:2017 focuses on circular screwing dies for parallel pipe threads (G series), primarily used to produce threads where pressure-tight joints are not achieved through the threads themselves.Dimensional Specifications
The document provides detailed dimensions for various thread sizes, including:- Basic diameter ranges from approximately 7.7 mm to 65.7 mm.
- Thicknesses, diameters, and fixing dimensions are standardized for compatibility.
- Pitch and thread designations correspond to nominal pipe sizes (e.g., 1/16 to 2 1/4 inches).
Marking Requirements
Dies are marked with the letter "G" followed by their thread designation (e.g., "G 3/8"), allowing easy identification and ensuring compliance with the standard. Manufacturers may append the ISO symbol to confirm full compliance.Compatibility and Interrelationship
The standard ensures compatibility with die stocks per ISO 2568 and provides an informative annex relating its thread designations to ISO 13399 cutting tool data representation standards.
Applications
SIST EN ISO 4231:2017 is essential for manufacturers, distributors, and users of hand and machine-operated screwing dies involved in:
Pipe Thread Manufacturing
Producing standardized parallel pipe threads crucial in plumbing, fluid transport, and mechanical assemblies requiring precise fitting without pressure-tight sealing on the threads.Tooling Compatibility
Ensuring dies are interchangeable with standard die stocks, reducing tooling costs and simplifying maintenance in workshops and production lines.Quality Assurance
Supporting metric/imperial thread consistency and standardization across European and international markets, improving safety and performance in pipe connections.Industrial Sectors
Widely applicable in construction, oil and gas, water supply, HVAC, and manufacturing industries where reliable parallel pipe threads are necessary.
Related Standards
- ISO 228-1: Specifies dimensions, tolerances, and designations for pipe threads where pressure-tight joints are not made on the threads.
- ISO 2568: Covers dimensions and requirements for hand- and machine-operated circular screwing dies and hand-operated die stocks, forming a basis for EN ISO 4231 die dimensions.
- ISO 4230: Defines circular screwing dies for taper pipe threads - R series, supplementing the G series covered by ISO 4231.
- ISO 13399: Provides standards for cutting tool data representation and exchange, with annex A of EN ISO 4231 linking designations to ISO 13399 symbols.
Practical Value
Adhering to SIST EN ISO 4231:2017 enables manufacturers and end-users to:
- Achieve uniformity in thread production tools for parallel pipe threads ensuring consistency and fit.
- Simplify inventory by standardizing die sizes and their compatibility with die stocks.
- Enhance tool traceability and compliance through standardized marking.
- Facilitate international trade by adopting a common standard recognized across CEN member countries and globally.
For professionals in tooling, pipe fitting, and mechanical assembly, compliance with SIST EN ISO 4231:2017 is a key factor in delivering dependable thread production, streamlined operations, and internationally compatible connections.
