Overview: This document outlines the specifications and applications for flexible tubes and rigid conduits, particularly focusing on the SP series of flexible conduits used in hazardous areas.

Specifications: The flexible conduits are designed for hazardous environments classified as II 2G EEx-d IIB/IIC with an IP 66 rating. They adhere to standards EN 50014 and EN 50018/IEC 60079.1, making them suitable for zones 1 and 2.

Materials and Construction: The conduits are made from AISI 304 stainless steel with braiding in AISI 321 stainless steel for sizes up to 3/4" and AISI 316TI for sizes 1" and above. Connectors are available in AISI 303 stainless steel up to 3/4" and galvanized steel from 1".

Applications: These conduits are ideal for connecting misaligned equipment or equipment subjected to vibrations, such as electrical motors. They are also suitable for lighting fixture installations and as alternatives to rigid tubes in challenging installations.

Product Range: The SP series includes various models with detailed dimensions, types, gas group classifications, and weights. The range is entirely available in stainless steel, with options for different thread types upon request.

Key Features: The SP series is noted for its flexibility and excellent vibration damping capacity. The conduits are available with fixed male or neutral female connectors, depending on the model.

Specifications: The document details various sizes of flexible conduits and rigid tubes, specifying dimensions and types such as 'neutral male - fixed male' and 'maschio folle - maschio fisso IIB'. Sizes range from 1” 1/2 to 3” for flexible conduits and from 1/2” to 4” for rigid tubes.

Procedures: Rigid tubes are used in explosive zones for connecting electrical equipment. They are designed to form a complete explosion-proof system when used with sealing unions. The tubes are internally smoothed to prevent damage to electrical cables.

Standards and Compliance: The document references compliance with directives 94/9/CE and standards EN 50014 - EN 50018, applicable to zones 1 and 2. Installation guidelines follow EN 60079.10.

Construction and Features: Rigid tubes are made of galvanized steel with a standard length of 6 meters. They include plastic couplings for thread protection and use ISO7/1 threading, with other threading options available upon request.

Options: Various threading options are available upon request to suit different installation needs.
