Overview
SIST EN 3730:2009 is a European standard developed by CEN that specifies the requirements for aerospace-grade saddle clamps made from aluminium alloy with rubber cushioning. These clamps are designed primarily for pipe assemblies in aerospace applications. The standard covers both fixed (type 1) and sliding (type 2) clamp versions, focusing on their dimensions, masses, materials, surface treatments, and marking for identification.
Designed for use at temperatures up to 80 °C, these clamps incorporate rubber cushion materials certified under related standards to ensure thermal and environmental compliance. SIST EN 3730:2009 supersedes the previous 2001 edition and provides updated specifications to meet modern aerospace requirements.
Key Topics
Materials
- Aluminium alloy compliant with EN 2693 (AL-P5086-H111).
- Cushion materials include:
- Silicone rubber (VMQ) per EN 2261 (color: rust).
- Fluorosilicone rubber (FVMQ) per EN 3826 (color: blue).
- Fluorocarbon rubber (FPM) per EN 2566 (color: brown).
- Rubber cushions comply with EN 4115 for dimensions and properties.
Clamp Types and Configuration
- Type 1: Fixed saddle clamps (code J).
- Type 2: Sliding saddle clamps (code K).
- Each clamp consists of two halves (top and bottom) with specified forms (A, B, C) and precise dimensions to accommodate different pipe diameters.
Dimensions and Masses
- Dimensions are detailed in millimeters with strict tolerances ensuring interchangeability.
- Masses are provided per 1,000 pieces with specifics for each clamp part to aid design and weight calculations.
Surface Treatments
- Options include none (code 0) or yellow chromate coating (code 1) according to EN 2437 to enhance corrosion resistance.
Marking and Designation
- Clamps are clearly marked in compliance with EN 2424 for traceability.
- Marking includes standard number, diameter code, form code, cushion material color, and surface treatment identifier.
Technical Specifications and References
- Referenced standards for related materials and processes include EN 2261, EN 2424, EN 2437, EN 2566, EN 2693, EN 3078, EN 3825, EN 3826, and EN 4115.
- Clamps must meet the aerospace industry's high reliability and safety standards.
Applications
SIST EN 3730:2009 clamps are essential components for aerospace fluid systems, providing secure pipe support while minimizing vibration and wear. Typical applications include:
- Aircraft hydraulic and fuel pipeline assemblies.
- Support systems in space vehicles and satellites.
- Aerospace manufacturing and maintenance for dependable pipe fixation.
- Environments requiring lightweight, corrosion-resistant clamp solutions with rubber cushioning to protect pipes from mechanical damage.
Their ability to operate at elevated temperatures up to 80 °C (with optional higher temperature usage) and compliance with international aerospace specifications make them indispensable in critical aerospace fluid systems.
Related Standards
- EN 2693 – Aluminium alloy specifications for aerospace components.
- EN 4115 – Rubber cushions for clamps dimension and mass standards.
