Product Description
A Steel wire wrapped skeleton reinforced polyethylene composite pipe(DN50-630mm)
B Flexible composite high-pressure conveying pipe(DN50-150mm)
| Steel wire wrapped skeleton reinforced polyethylene composite pipe: Polyethylene resin (polyethylene HDPE, heat-resistant polyethylene PE-RT, etc.) is used as the base material, the steel mesh skeleton is the reinforcement, and the extruded steel skeleton reinforced polyethylene composite pipe is used.(Steel wire wrapped skeleton reinforced polyethylene composite pipe) | Flexible composite high-pressure conveying pipe: It uses polyethylene resin (polyethylene HDPE, heat-resistant polyethylene PE-RT, cross-linked polyethylene, polyvinylidene fluoride) as the base material, and polyester, aramid, steel wire rope, ultra-high molecular weight polyethylene filament, etc. as reinforcements. Extruded flexible composite high-pressure conveying pipe. |
The standards implemented are the oil and gas industry standards of the People's Republic of China: SY/T 6662.1-2012 Non-metallic composite pipes for the oil and gas industry Part 1: Steel skeleton reinforced polyethylene composite pipes(Steel mesh skeleton reinforced polyethylene composite pipe) SY/T 6662.2-2020 Non-metallic composite pipes for the oil and gas industry Part 2: Flexible composite high-pressure conveying pipes
It is mainly composed of five layers: the inner and outer layers are made of thermoplastic plastic, made of HDPE, PERT, etc., and the middle layer is a steel wire reinforcement layer that has been coated with rubber. A layer of bonding resin is added to both sides of the steel wire reinforcement layer to make the reinforcement layer and the inner and outer layers Bonded into one.
It is mainly composed of three layers: the inner thermoplastic pipe is made of thermoplastics such as HDPE, PERT, PA, and PVDF. The middle layer is a reinforced material layer wound at a specific angle. The materials include aramid fiber, polyester fiber, glass fiber, etc. The outer layer is a protective layer, usually HDPE with anti-aging and anti-UV added.
Nominal pressure:
The maximum working pressure of composite pipes and fittings when transporting media at 20°C. The unit is megapascal (Mpa).
Average outer diameter:
Use the circumference method to measure the value of the circumference of the outer wall of the composite pipe divided by 3.142 (pi). The result is rounded to 0.1mm. If the second digit after the decimal point is greater than zero, it is rounded up to one digit. The unit is millimeters (mm).
Nominal outer diameter:
The number identifying the size represents the outer diameter of the composite pipe. Use an integer and the unit is millimeters (mm).
Polyethylene compounding ingredients:
Pellets made from polyethylene base resin with necessary antioxidants, UV stabilizers and pigments.
1. Preservative
2. High pressure
3. Heat resistant and preservation
4. Strong conveying capacity
5. Good flexibility
6. Convenient construction
7. Few connectors
8. High cost performance
9. Good hygienic performance
10. Long lasting
Composite pipes should be laid flat or rolled up, and the stacking height should not exceed 3.0m. Composite pipe reels are not permitted to be suspended from a fixture.
When transporting, lift the grab strips on the packaging at the same time to keep the composite pipe basically straight. When using machinery, lifting rings or wire ropes to lift composite pipes, it is necessary to prevent damage to the outer cladding of the composite pipes.
During transportation, avoid sunlight, rain and snow; prevent contact with some substances that can damage the composite pipe, and keep it at least 1m away from heat sources.
