Multicore Tubing

Multicore Tubing Solution

BAOFENG provides multicore tubing solutions that integrate multiple stainless steel tubes into a single protected bundle for instrument, hydraulic, pneumatic and chemical injection applications.

Compared with installing multiple individual tubes separately, a multicore tubing bundle simplifies routing, improves line identification and helps reduce the number of separate components handled during field installation.

Why Multicore Tubing?

Industrial control and instrumentation systems often require several small-bore tubing lines to run between field equipment, control panels and process units.

Installing each tube independently can increase routing complexity, installation work and identification difficulty.

Multicore tubing combines multiple tubes into one organized assembly, helping to:

• Simplify field routing
• Reduce installation work
• Improve identification of individual lines
• Protect tubing against abrasion and environmental exposure
• Reduce the number of separate components installed in the field
• Support multiple control functions within one compact bundle

BAOFENG’s multicore tubing design uses individually identifiable tube lines and protective sheathing to support installation in demanding industrial environments.

Typical Applications

BAOFENG multicore tubing can be used for:

• Valve remote control lines
• Wellhead control panel lines
• Hydraulic control lines
• Instrument control lines
• Chemical injection lines
• Fire control lines
• Fixed gas detection sensor lines
• Pressure sensing lines
• Deck machinery remote control lines
• Heat tracing related control lines

These application areas are directly listed in BAOFENG’s multicore tubing materials.

Tube Material Options

Typical tubing materials include:

• 304L
• 316L
• Duplex stainless steel
• High-nickel alloys

Material selection depends on corrosion environment, pressure, temperature, service medium and project requirements.

BAOFENG’s multicore tubing specification tables specifically identify 304L, 316L, duplex stainless steel and high-nickel alloys as available material categories.

Multiple Tube Configurations

Multicore tubing can be configured with different numbers of internal tubes according to the required control functions.

BAOFENG’s documented configurations include assemblies with:

• 1 core
• 2 cores
• 3 cores
• 4 cores
• 5 cores
• 6 cores
• 7 cores
• 8 cores

This allows several hydraulic, pneumatic, instrument or chemical lines to be combined into one integrated bundle.

Typical Tube Sizes

BAOFENG multicore tubing configurations include commonly used tube sizes such as:

• 1/4″ × 0.035″
• 8 × 1.0 mm
• 10 × 1.0 mm
• 3/8″ × 0.035″
• 12 × 1.0 mm
• 1/2″ × 0.049″

The total bundle diameter varies according to tube size, number of cores and sheath thickness.

Pressure Capability

For several documented BAOFENG multicore tubing configurations, typical values include:

• Working Pressure: 180 bar
• Testing Pressure: 270 bar

Actual pressure capability depends on tube material, OD, wall thickness and project-specific operating conditions.

Protective Sheathing

Multicore tubing can be supplied with protective outer sheathing to improve resistance to:

• Abrasion
• Water
• Oil
• Corrosion
• Aging
• Complex outdoor environments

BAOFENG’s multicore tubing materials also describe color-coded PVC sheathing, allowing individual tubes to be identified more easily during installation and maintenance.

Easier Installation and Line Identification

One of the main advantages of multicore tubing is installation efficiency.

Instead of routing and securing several individual tubes one by one, multiple lines can be installed as a single bundle.

Different tube lines can also be identified by color, making connection, commissioning and maintenance more convenient.

For projects with many parallel control lines, this can significantly simplify field organization.

From Individual Tubes to an Integrated Bundle

BAOFENG can configure the multicore tubing solution according to the project requirement:

Tube material → OD & wall thickness → Number of cores → Line identification → Protective sheath → Pressure requirement → Testing → Coil length → Project delivery

The final configuration is selected according to the number of required control lines and the actual installation environment.

Project-Based Configuration

To recommend a suitable multicore tubing configuration, please provide:

• Number of tube lines
• Tube material
• OD × wall thickness
• Working pressure
• Service medium
• Required bundle length
• Installation environment
• Sheathing requirement
• Color identification requirement

BAOFENG can then recommend a suitable multicore tubing arrangement according to the project conditions.
