Product catalog summary

System Description
The FLEXWELL® Safety Pipe is a double-walled, flexible pipe system designed for the safe transport of hazardous fluids. It includes a leak detection system and meets European safety standards. The pipe dimensions range from DN 12 to DN 100, with a pressure capacity of 25 bar and a temperature range of -10°C to +50°C. It is constructed with stainless steel inner and outer pipes, encased in PE for corrosion protection.

Leak Monitoring
The system features a surveillance space between the inner and outer pipes for continuous leak monitoring using pneumatic devices. This space can be filled with inert gas or evacuated to prevent fluid escape. It complies with European standards for leak detection and provides acoustic and optical alarms in case of leaks.

Legal and Installation Requirements
Installation must comply with European standards and environmental legislation. The pipe can be installed both underground and above ground, with flexible options. Only trained and accredited firms are authorized to perform installations.

Advantages
The FLEXWELL® Safety Pipe offers operational safety and economic benefits, including easy system checks without downtime and reduced need for pressure tests or inspections. It is available in lengths up to 1000 meters, allowing for quick installation.

Product Overview
The document provides detailed specifications for various components, including piping, connecting fittings, through-connections, elbows, and T-pieces. Each component is described with its nominal bore, pressure capacity, and material specifications.

Construction Details
The pipe system includes a corrugated inner pipe, a surveillance space, a corrugated outer pipe, and a PE casing. Quality assurance is conducted through external and internal tests to ensure compliance with safety standards.

Specifications
The FLEXWELL® Safety Pipe FSR is constructed using stainless austenitic steel with material numbers 1.4404/1.4571 for inner parts and 1.4301 for outer parts. The joining method involves TIG welding or hard soldering, and only BRUGG solder Type BRL 8.50.34 is permitted. The pressure stage is PN 25, and insulation should comply with DIN 30762.

Procedures
Integrated through-connections and elbows are available, with specifications for each type including dimensions and article numbers. The integrated elbow is necessary when the minimal bending radius cannot be maintained. Monitorable elbows and T-pieces with flanged connections are also detailed, including their assembly and sealing requirements.

Standards and Recommendations
The document emphasizes the use of specific materials and methods, such as the exclusive use of BRUGG solder and compliance with DIN standards for insulation. It also highlights the importance of using suitable materials for sealing and insulation to ensure system integrity.

Key Data from Tables
The tables provide detailed specifications for various components, including dimensions, material types, and article numbers for different pipe sizes and configurations. These include integrated through-connections, elbows, and T-pieces, each with specific measurements and requirements.

Company Information
Brugg Rohrsystem AG and BRUGG Rohrsysteme GmbH are highlighted as providers of efficient solutions for transporting liquid materials, with a global network of partners. They offer customer-specific solutions and emphasize their expertise in single-wall, double-wall, and insulated pipe systems.

FLEXWELL® Safety Pipe System description Leak monitoring The FLEXWELL® Safety Pipe is permanently monitored using pneuma- tic leak detection devices/leak detectors. These regulate the monito- ring pressure in the surveillance space and register any changes of pressure which may occur. The surveillance space is either filled with an inert gas or evacuated and prevents the uncontrolled escape of the transport medium into the environment in the event of a leakage. The surveillance space must be constructed in such a way that the proper functioning and operating safety of the leak detection system...
