Product details
Product Features
-
1. Long service life
Under rated temperature and pressure conditions, it can be safely used for more than 50 years.
-
2. Excellent corrosion resistance performance
Except for a few strong oxidants, it can withstand erosion from various chemical media; No electrochemical corrosion.
-
3. Excellent wear resistance performance
After long-term use, it has been shown that the wear resistance is more than four times that of steel pipes.
-
4. Good hygiene performance
No heavy metal salt stabilizers are added during processing, the material is non-toxic, has no scaling layer, and does not breed bacteria, effectively solving the secondary pollution of urban water.
-
5. Good impact resistance
Good toughness, high impact resistance, and direct pressure of heavy objects on pipelines will not cause pipeline rupture.
-
6. Reliable connection performance
The strength of the hot melt electric fusion interface is higher than that of the pipe body, and the joint will not break due to soil movement or live load.
-
7. Good construction performance
The pipeline is lightweight, the welding process is simple, the construction is convenient, and the overall project cost is low.
-
8. Larger circulation capacity
The inner wall of the pipeline is smooth, the head loss is small, and the flow capacity is increased by more than 30% compared to other general pipelines.
Application field
-
-
1. Municipal tap water supply, diversion, and water treatment projects
2. Rural Healthy Drinking Water Project
3. Pipeline system for water supply inside and outside buildings
4. Old pipeline repair, water treatment engineering pipeline system
5. Industrial water pipes for landscaping, irrigation, and other fields
Product Parameters
PE water supply pipe connection method
-
Hot melt docking
Hot melt docking is a simple and fast method for connecting PE pipes, suitable for connecting pipes and fittings with a diameter greater than 63mm. The welding procedure can be found in the following content. In order to achieve the best welding effect, it is necessary to control the entire welding process well and comply with the welding parameters.
-
Pipe fittings connection
PE water supply pipes can be connected by injection molded fittings, welded fittings, electric fusion fittings, steel plastic conversion joints, or other forms of mechanical fittings. Generally, pipes with a diameter less than 63mm are connected by hot melt socket fittings. For some special requirements, electric fusion fittings are used for connection.
-
flange connection
Typically, flange connections are used to connect PE pipes with valves or other materials of pipes and fittings.
Fusion welding procedure
- Fixing of pipes:Fix the pipe on the welding machine, leaving a space of 30-50mm, and fix the rotary cutting machine on the pipe end.
- Milling flat end face:Adjust the cutting machine and press it tightly against the pipe end before starting cutting. After cutting is completed, slowly reduce the pressure until the cutting machine stops working, which can ensure a smooth and flat cutting surface.
- Heating tube end:Insert the heating plate into the middle of the two ends of the heating tube.
- Welding:After heating the tube end, quickly move the heating plate away and squeeze the tube towards the middle.
- Complete welding:When the welding junction temperature drops to the same level as the ambient temperature, remove the pipe from the welding machine. After welding, the strength of the interface can reach or even exceed the strength of the pipeline itself.
