UNDERGROUND PIPE 

ADVANTAGE OF DOUBLE-WALLPIPE

·Double protection: our underground pipe system adopted coaxial pipe with “tube in tube” structure. The primary pipe has permeation barrier and the secondary containment pipe protect it and resist leakage.

·24 hours monitor: in order to ensure on danger, our underground pipe system contained leakage detecting instrument, it can monitor 24 hours, once oil leak occur, the system will be shut down automatically

·Easy to install: double pipe connection can be finished at one time, then buried directly

·Low installation cost: high density polyethylene pipe installation costs 50% lower than the steel pipe installation cost

ADVANTAGE OF OUR UNDERGROUND PIPE SYSTEM

·Static conductive, safety and reliable: proper static conductive electric-static conducting coating in our underground pipe system can remove static electricity when fluid is flowing in pipe

·materials of impervious layer without any modification, then original super high barrier property of the materials is kept, it prevents medium transported in pipe from polluting soil and water

·Long working life: our company promised 30 years warranty

·Powerful loading capacity, resilient and reliable: our underground pipe system has strong capacity for resisting compression, shock, puncture, stretch, ground movement. It can resist crustal stress, so that ground movement won not affect tightness of every connected position, consequently, safety of piping system in gas station can be ensured

·Resistant corrosion, wide application: our underground pipe system has strong corrosion resistance, never rusts, this advantage much reflects in areas with strong corrosion resistance of soil, coastal high humidity, high salinity. our underground pipe system can work in soil with humidity within -40~50℃, it is suitable for most areas

·Safe and efficient installation:  welding of our underground pipe system can be finished by a kind of special intelligent welding machine, ensuring the installation rapid and safe.

DOUBLE-WALL STRUCTURE

In order to ensure no leakage, the double-wall conductive petrol has permeation barrier and secondary containment. It can ensure the safe use in a short period once the primary pipe leak

There is a larger gap between the primary pipe and the secondary containment pipe, it can ensure 24 hours monitoring

Non-corroding, service life is long, it is able to bear various chemical mediators, no electrochemical corrosion

It is burst pressure exceeds 40 standard atmospheric pressure, ten times of working pressure, so that higher safety can be kept

Working temperature range from -40to 50℃ with excellent capability

Lightweight, convenient for transport and installation.

CONDUCTIVE PETROL PIPES WITH PERMEATION BARRIER AND SECONDARY CONTAINMENT

PIPE FITTING ADVANTAGE

·Electrofusion welding is adopted, the welding voltage is low, safe and reliable. Double pipe connection can be finished at one time

·All fittings ate connected, in order to ensure the monitoring of the whole pipeline

·The bend radius of 90°elbow is big, that cuts the flow loss in the process of medium transmission

·The structure of straight coupling and tee union is special, it ensures that no permeation in all pipe system

·Conductive plug-in ensures the continuity of piping system, makes it to be a conductive pipeline system

SINGLE-LAYER STRUCTURE

·Impermeable layer is made from pure EVOH without any modification for the sake of the best separation impact. This impermeable layer can be used together with all kinds of fuel oil, ethanol mixture and additive, it is ensured to be appropriate for all of karyotypes of fuel in the world;

·The proper five-layer structure makes the layers can be pasted in each other preferably;

·Resistor of conducting shell is less than 104 Ω;

·Non-corroding, service life is long, it is able to bear various chemical mediators, no electrochemical corrosion;

·Its bursting pressure exceeds 40 standard atmospheric pressure, ten times of working pressure, so that higher safety can be kept;

·Working temperature range from -40℃ to 50℃, with excellent capability of corrosion resistant, especially in coastal areas, saline areas, compared with steel pipe, it has incomparable advantages;

·Lightweight, convenient for transport and installation.

PIPE 5 ADVANTAGE

·Electrofusion welding is adopted, the welding voltage is low, safe and reliable;

·In the welding process, no spark and naked light;

·The bend radius of 90°elbow is big, that cuts the flow loss in the process of medium transmission;

·The structure of straight coupling and tee union is special, it ensures that no permeation in all pipe system;

·Conductive plug-in ensures the continuity of piping system, makes it to be a conductive pipeline system.
