It is the safest system among the direct-buried heat carrying pipe systems. Heat-carrier pipes can be freely sliding in the casing pipe to prevent damages of the carrier pipes caused by thermal expansion. This cutting-edge energy saving pipe technology of  Daekyung-Enertech Co., Ltd. Is patented. It does not need conventional concrete trench/channel, insulation work in the field or the other bothering works.

FLEXIBILITY

This system can be applied and suitable to various customer’s requirements, i.e. hot and cold heat conservation; high temperature steam; extremely low temperature liquidate gas, or etc.

 

DURABILITY

Casing pipe is PE coated to prevent corrosion, aging of the insulation and heat loss

 

COMPETITIVE

It is not necessary to construct underground protection structure (e.g. concrete trench, channel), which gives benefits of cost saving and construction period shortening.

 

RELIABILITY

Because this system originally reduce the conventional damage of heat carrying pipes, this outstandingly reduce defect and extend life time.

CARRIER PIPE

Selected in consideration of the operation pressure, temperature and the corrosion of the pipes as per the engineering specifications.

 

INSULATION

ROCKWOOL, HITLIN are used and the thickness of the insulation can be selected as per the condition of the fluid temperature.

 

CASING PIPE

Carbon steel pipe coated with PE, asphalt to protect the surface from corrosion.

 

AIR EVACUATED SPACE

Vacuum processing makes the carrier pipe smoothly move and slide within the casing pipe so as to minimize a heat loss or gain.

 

ROLLER SUPPORT

Roller support keeps the space between the pipes uniformly and makes the carrier pipe move smoothly.

 

LEAK DETECTION SYSTEM (OPTIONAL)

Monitoring system used for positioning the leaking points caused by the damages on the pipes, which can be applied to all kinds of conductive fluid or gaseous material.

 

 

 

ROLLER SUPPORT

Roller support keeps the space between the pipes uniformly and makes the carrier pipe smoothly slide within the pipe during thermal expansion. For better sliding, roller or guide is attached to the points where it contacts the casing pipe and clamped at the exterior of the carrier pipe. At this time, compression-resistant insulation and insulated pad are wound around and between the clamp and the pipe, which prevents heat from being transferred to the support.

 

 

 

END SEAL UNIT

End seal unit is a BELLOWS-TYPE termination and gas and vacuum-tight cap that allows the axial movements of the carrier pipe.

 

 

MANHOLE ENTRY UNIT

Similar to the end seal unit in its purpose and structure but used for the perfect waterproofing when the pipe runs through the manhole or the wall of building structure, being affected by thermal expansion

 

 

 

SIZE

* Length, insulation thickness and the sizes of the casing pipes vary as per the design specifications.

BRENDES Leak-Detection System

 

 

1.SYSTEM OUTLINE

Brandes Leak Detection System detects any leakages or water infiltration occurred by the damage and ageing on the underground pipe line and position the leaking points and monitor the leaking degree.

 

2. CENTRAL MONITORING SYSTEM

- Controlling and analyzing the monitoring device

- BS-1030 statcon : Securely monitoring the system

- Central monitoring length : 200km

- SDT (Sensor-Data-Transfer) function added (use separate signal line)

  Data transfer to central monitoring system through the telephone line in case of poor data transfer duet to the interference of other construction activities.

 

3. MONITORING DEVICE

- Monitoring sensor wires

- Monitoring scope : 2,000m

 

4. POWER SUPPLY & SIGNAL PROTECTION DEVICE

- Supplying power to the monitoring device and solving signal troubles

- Maximum link : 10 units

 

5. BS-FA SENSOR WIRE

- Detecting the leakages or water infiltration
