Cable Transits

Whitepaper | Roxtec Multi-Cable Transit Devices

Abstract

This is an introduction to applications and an engineering design approach for the proper use of Roxtec multi-cable transit devices within onshore oil, gas and petrochemical facilities. This paper demonstrates improved safety and improved project delivery when cable transit devices are included into owner and EPC design scopes.

International standards for cable transit devices and common safety demands are presented, including the use of Roxtec cable transit devices for vapor-tight barriers, blast-rated structures, fire walls, pressurized buildings, and simple ingress protection against environmental elements.

Incorporating Roxtec transits into owner-level and engineering-level design standards, is demonstrated to provide project savings that include reducing contractor work-hours, detail design time, and reduced field maintenance time. Proper multi-cable transit design and installations are also shown to increase project safety and operational uptime.

Whitepaper | Modular Integration of Process Equipment Packages for Oil and Gas Facilities

Abstract

An integrated design approach to a modular process equipment package is discussed. By incorporating the electrical, instrumentation and control equipment on the same platform as the process equipment, a higher level of modular integration is achieved.

The benefits include a reduced number of on-site equipment terminations and the ability to precommission equipment prior to installation resulting in lower installed costs. The area classification, installation and cable transit barrier requirements for an integrated modular design approach are reviewed.

Non-welded Fireproof & Watertight Pipework Seals for Marine Vessels from Roxtec

Roxtec Cable Seals

Non-welded Fireproof & Watertight Pipework Seals

Marine Vessels from Roxtec

Use Roxtec sealing solutions for single and multiple metal pipes to protect life and assets against fire, gas and water ingress.

Owners, shipbuilders and construction companies all over the world appreciate the excellent fire-stopping and watertight features of our certified sealing system.

Roxtec metal pipe cable transits maintain deck and bulkhead fire classifications as defined by IMO as well as fire ratings for walls, panels and other structures with openings for pipes. They are available for a variety of environments and use, for round and rectangular openings and for high demand areas.

Covering a wide range of systems

Marine vessels, for example, have complex webs of pipework to feed essential systems such as engine transfer systems, hydraulic fluid systems and various water systems. This means variations in pipe materials, and tough demands for sealing systems. We provide seals for many applications, and our metal pipe seals are ideal for maintaining the integrity of marine rated divisions penetrated by:

• Water pipes
• Wastewater pipes
• Hydraulic pipes
• Pneumatic pipes
• Transfer and distribution systems
• Sprinkler systems
• Restaurant and beverage pipes

Cable & Pipe Sealing Transits & Systems

Roxtec metal pipe seals are resistant to:

Fire

Stop A, B, H and jet-fire. Prevent smoke from spreading.

Gas

Ensure complete tightness against air and gas pressure up to 2.5 bar.

Water

Prevent humidity and water ingress. Keep tight against water pressure up to 6 bar.

Electromagnetism

Protect against effects of EMI and EMP.

Threats to Electrical Safety

Ensure electrical safety via potential equalization.

Blast

Protect against noise, vibration and the risk of explosion.
