Overview
This comprehensive technical guide covers essential aspects of industrial fastener applications, providing practical guidance for engineers, procurement specialists, and maintenance teams based on LOKRON's two decades of experience.
Technical Requirements
Understanding applicable standards and specifications is crucial for proper material selection. Primary standards include relevant ASTM, ASME, EN, and ISO specifications.
Key Specifications
| Specification | Scope | Key Requirement |
|---|---|---|
| ASTM/ASME | Material properties | Tensile, yield, hardness limits |
| EN Standards | European compliance | PED certification where applicable |
Material Selection
Selection depends on operating temperature range, process fluid chemistry, mechanical loading, and environmental exposure.
Design Considerations
Proper design requires careful analysis of joint geometry, load distribution, thermal expansion, and long-term service conditions.
Installation and Quality Control
- Surface preparation and thread lubrication per ASME PCC-1
- Torque-tension relationship control using calibrated tools
- Multi-pass tightening sequences for uniform gasket compression
- Post-installation verification using ultrasonic or direct methods
LOKRON Supply Capability
LOKRON manufactures and supplies fasteners with complete material traceability (EN 10204 Type 3.1 certificates), PED certification where applicable, and custom engineering support.
