2. core products: Wo Hong brand double buried composite pipe

2.1 Product overview

Wo Hong brand double-layer buried composite pipe is a high-performance pipe specially designed for oil transportation in gas stations. It adopts innovative double-layer composite structure,

It is widely used in scenarios such as oil filling pipelines, oil unloading pipelines, ventilation and oil and gas recovery pipelines, and impermeable jacket pipelines.

2.2 structure design

The product uses a coaxial "tube in tube" structure:

Outer layer: High-strength polyethylene (PE) material, which protects the internal pipeline from external influences and has excellent corrosion resistance.

Inner layer: high compression resistance, corrosion resistance of special materials, withstand high pressure and high flow demand, to ensure the stability of oil delivery.

Intermediate layer (optional):EVOH high barrier material, ultra-high barrier, to prevent leakage of media.

2.3 product specifications

The main models of composite pipes for gas stations provided by Wo Hong are as follows:

Product specification corresponds to tubing model

Φ63×2.8mm           Φ73×5.51mm

Φ63×4mm             Φ73×5.51mm

Φ65×2.5mm           Φ73×5.51mm

Φ65×3mm             Φ73×5.51mm

Φ76×3.5mm           Φ88.9×6.45mm

Φ76×4.5mm           Φ88.9×6.45mm

2.4 core advantages

(1) Double anti-seepage protection

The double-layer "tube-in-tube" structure with EVOH high barrier material, the impermeable layer maintains the original ultra-high barrier property of the raw material, effectively preventing

Pollution of soil and water source by medium in pipe.

(2) Electrostatic conductivity

Products with excellent antistatic properties, effectively reduce the risk of static electricity accumulation, significantly reduce the risk of fire, suitable for a variety of liquids

Storage and delivery.

(3) long service life

Composite pipes made of EVOH material ensure a 50-year service life and have significant long-term stress cracking resistance at high temperatures (can be

up to 110 ℃), excellent high temperature resistance.

(4) strong weather resistance

Excellent low temperature impact strength, the use temperature can be as low as -50 ℃; high wear resistance and mechanical resistance, suitable for poor conditions

Site environment; excellent chemical resistance.

(5) Easy installation

All pipelines, joints, tees and other components are prefabricated in the factory, and the finished pipeline components are directly assembled on site with lightweight design.

Significantly reduce construction time and costs.

(6) Intelligent monitoring

The system is equipped with a leakage monitoring alarm device, from the oil tank to the core process of the tanker to achieve full online monitoring, for the gas station.

Safety and number of quality management escort.

3. supporting pipe fittings and systems

Wo Hong offers complete composite pipe system components, including:

Direct connector (electrofusion/hot melt)

· 90 ° elbow

· Tee

· Flange Adapter

· Threaded Adapter

· Terminal pipe cap

Terminal pipe joint with detection interface

All fittings are matched with the tubing to ensure system compatibility and tightness.
