Municipal Drainage Project Yima 560pe water supply pipe

  China's plastic pipelines are developing rapidly and their quality is constantly improving
At present, a plastic pipe industry dominated by polyvinyl chloride (PVC-U) pipes, polyethylene (PE) pipes and polypropylene (PP-R) pipes has initially formed
Polyethylene (PE pipe) is widely used in building water supply, building drainage, buried drainage pipe, building heating, gas transmission pipe, electrical and Telecommunications protection sleeve, industrial and agricultural pipe, etc
because of its unique advantages
It is mainly used in urban water supply, urban gas supply and farmland irrigation PE water supply pipe is a plastic pipe made of professional polyethylene and extruded by plastic extruder at one time
It is used in urban water supply network, irrigation and drinking water projects, garbage disposal sites, sewage collection pipeline projects and agricultural sprinkler irrigation projects
Because PE pipes are connected by hot melting and electrothermal melting, the integration of the interface with the pipe is realized, and the circumferential stress and axial impact stress caused by internal pressure are effectively resisted
Moreover, PE water supply pipes do not add heavy metal salt stabilizer, and the material is non-toxic, non scaling, non breeding bacteria, avoiding the secondary pollution of drinking water, It is a new generation of PE pipe, water supply pipe

 
Characteristics of PE water supply pipeline
1
Good sanitary performance: PE pipes are processed without adding heavy metal salt stabilizers
The material is non-toxic, has no scaling layer, and does not breed bacteria, which well solves the secondary pollution of urban drinking water
2
Excellent corrosion resistance: except for a few strong oxidants, it can resist the corrosion of a variety of chemical media; No electrochemical corrosion
3
Long service life: PE pipes can be safely used for more than 50 years under rated temperature and pressure
4
Good impact resistance: PE pipe has good toughness and high impact strength
Heavy objects directly press the pipe, which will not cause pipe rupture
5
Reliable connection performance: the strength of PE pipe hot-melt or electric fusion interface is higher than that of the pipe body, and the joint will not be disconnected due to soil movement or live load
6
Good construction performance: the pipeline is light, the welding process is simple, the construction is convenient, and the comprehensive cost of the project is low Connection of pipes:  
7
Electrothermal fusion: use special electrothermal fusion welding machine to connect straight pipes with straight pipes and straight pipes with pipe fittings
It is generally used for pipes below 160mm
8
Hot melt butt joint connection: special butt welding machine is used to connect pipes, which are generally used for pipes above 160mm
9
Steel plastic connection: flange, screw thread and other methods can be used for connection

  Installation and maintenance of PE pipes:
  1
Before installation, check whether the pipe groove meets the installation requirements, and then check whether the appearance of the pipe has obvious dents, cracks, scratches, scratches, and replace it in time in case of quality hazards
  2
C20 concrete buttresses are used at pipe elbows, tees, tapered joints, fire hydrants, etc
, and flange valves are reinforced with brick buttresses
  3
When PE water supply pipes are connected with metal pipes, valves and fire hydrants, steel plastic transition joints or special flanges must be used

  4
Vent valves shall be set at the uplift or uphill sections of the pipeline to reduce the impact of the mixed pressure of gas and water on the pipeline
The ratio of pipeline to exhaust valve is designed to be 1:8
  5
Due to the good flexibility and scalability of PE pipes, the installation of expansion joints is not considered in all pipe installations
  4、 Backfill compaction  
  After the completion of pipeline installation and laying, backfilling shall be carried out immediately after the acceptance of concealed works, and the backfilling shall comply with the following provisions:  
  1
Prevent the water in the tank from causing the pipeline to float
If there is water, try to drain it out
  2
When backfilling the pipe trench in the stonework and earth rock mixed section, the clay or sandy soil shall be transported and backfilled to the top of the pipe 200-300mm, and then other miscellaneous soil shall be backfilled after compaction
  3
Backfilling must be carried out from both sides of the pipe at the same time, and one layer of backfilling must be compacted
  4
Before the pipeline pressure test, generally, the backfill should not be less than 500mm
5
The large-area backfilling after the pipeline pressure test should be carried out when the pipeline is full of water, and the pipeline should not be empty for a long time after laying
