Water supply pipe
1. Product concept:
It is made of special polyethylene as raw material and extruded by plastic extruder. It is applied to plastic pipes of town gas, water supply network, gas pipe network, irrigation water diversion project, garbage disposal site, sewage collection pipeline engineering and agricultural sprinkler irrigation project. Since the PE pipe adopts hot melt and electric hot-melt connection, the interface and the pipe are integrated, and the hoop stress and the axial impact stress generated by the internal pressure can be effectively resisted, and the PE pipe does not add the heavy metal salt stabilizer. Non-toxic, non-scaling, no bacteria, avoid secondary pollution of drinking water, specifications Q25-Q630, low price.
2. Performance characteristics
Since the PE pipe adopts hot melt and electric hot-melt connection, the interface and the pipe are integrated, and the hoop stress and the axial impact stress generated by the internal pressure can be effectively resisted, and the PE pipe does not add the heavy metal salt stabilizer. It is non-toxic, non-fouling, and does not breed bacteria, avoiding secondary pollution of drinking water.
1. Long service life - PE pipes can be safely used for more than 50 years under rated temperature and pressure conditions.
2, excellent corrosion resistance - in addition to a few strong oxidants, can withstand the erosion of a variety of chemical media; no electrochemical corrosion.
3. Excellent anti-wear performance - When transporting ore mud, the wear resistance of PE pipe is more than 4 times that of steel pipe.
4, good hygienic performance - PE pipe processing does not add heavy metal salt stabilizer, the material is non-toxic, no fouling layer, no bacteria, better to solve the secondary pollution of urban water.
5, better impact resistance - PE pipe has good toughness, high impact strength, heavy weight directly pressed through the pipe, will not lead to pipe rupture.
6. Reliable connection performance - The strength of the PE tube hot melt electrofusion interface is higher than that of the pipe body, and the joint will not be broken due to soil movement or live load.
7. Good construction performance - the pipeline is light in weight, the welding process is simple, the construction is convenient, and the comprehensive construction cost is low.
In addition, polyethylene pipes have many excellent properties, such as low temperature resistance, good toughness, and softness and softness. Therefore, in some special applications, it is even more important, because in these fields, traditional material pipes are not inapplicable, they are expensive, and they cannot guarantee the safe use of pipes. The biggest problem with steel pipes and cast iron pipes is the widespread corrosion and joint leakage during the service life. Polyethylene pipes have obvious advantages, which successfully solve the two problems of corrosion and joint leakage of traditional pipes. For example, it is used as an outdoor line pipe to be laid in corrosive soil, earthquake areas, mountains and swamp areas; it is inserted into old pipes as a socket to repair and renew old pipes. Due to the unique construction characteristics, it often brings huge economic benefits to users. As reported in the US, the installation cost of polyethylene pipes is 50% lower than the installation cost of steel pipes, and the intercalation method saves 30-40% compared with the direct buried method of polyethylene pipes.
Third, the scope of application:
Plastic pipes used in urban water supply networks, irrigation water diversion projects, garbage disposal sites, sewage collection pipeline projects and agricultural sprinkler irrigation projects
1. Water, rain and sewage pipes in cities such as apartments and residential gardens
2. Ground center protection and communication cable protection
3. Irrigation waterway, agricultural water (farm consolidation)
4. Sewage pipelines such as factories and farms
5. Drainage pipes for golf courses, sports fields, vehicles, roads, squares, etc.
6, the end of the water treatment site, the waste disposal site
7, all kinds of water crossing points
Fourth, product parameters:
1. Chemical resistance: It is not corroded by sewage, waste water and chemicals, and is not corroded by decaying substances in the soil;
2. Anti-shock: The pipe wall adopts the "I-shaped" structure, which is resistant to impact and pressure, and does not rupture under the condition of foundation sinking, and the recovery after deformation.
Strong, good adaptability to any foundation;
3, anti-aging: the pipe is usually black, can withstand the direct sunlight of the sun during storage and construction;
4. Cold resistance: the pipe will not be cracked and expanded and leaked in the environment of -60 °C;
5, light weight: easy to transport, construction is convenient, is 1 / 8 of the weight of the cement pipe, the buried pipe only requires an excavator, no large equipment;
6. Convenient connection: the pipe can be connected outside the ditch and pushed into the ditch with the excavator to reduce the engineering time and cost;
7. Excellent wear resistance: it is more wear-resistant than steel pipe and cement pipe, and has strong transport capacity of domestic water waste residue;
8. Excellent drainage and circulation: the interior is smooth, the friction is reduced, and the drainage speed is fast;
9. Economical: low construction, management and maintenance costs;
10. Environmental impact: HDPE is a non-toxic raw material, harmless to the environment such as land, and fully recyclable.
