Technical Standards
The production and construction shall be in strict accordance with INTERNATIONAL AND NATIONAL STANDARDS.
Germany DIN16961
BS EN13476   
Polyethylene Structure-Wall Piping System for Underground Usage--Part2: Polyethylene Spirally Enwound Structure-Wall Pipes(GB/T19472.2-2004)
Technical specification for buried PE pipeline of sewer engineering(CSCS 164:2004)
The design, construction and acceptance adhere to technical specification of buried polyethylene drainage pipe project (GB50268-2008)

Technical specification for buried plastic pipeline of sewer engineering (CJJ143-2010)


Raw Materials:
Special material like grade PE80 or grade PE100 for HDPE tubing; pp corrugated pipe as stiffening rib.
  
Manufacture Technique:
HDPE spirally enwound reinforced pipe has PE structured wall as its main support structure, and is formed through hot winding. Molding at constant high temperature is realized for the product in the production process from melting PE material particle to pipe forming; inner wall and outer wall are enwound simultaneously; natural air cooling is employed; bell-and-spigot type heat-fusion connection is adopted for the interface. The advanced production technology is leading in the world, determining excellent technical performance of the products.  


Performance Advantages:

Use the high quality PE materials
High Resistance to Corrosion
Resistance to Wearing
Excellent Hydraulic Performance
Green and Environment - friendly
The service life can be over 50 years though
PIPE Performance Advantages
Strong Resistance to Impact
High Ring stiffness above SN20
Seismic fortification intensity is as high as level 9
Convenient Connection
Good Sealing Performance
Light Weight
Low Construction Cost
Pipe -soil interaction
HDPE-wrapped reinforced pipe is a load-bearing structure system formed by both pipe and fill, that is to say, the pipe under load gains counter force through deforming in a moderate way while extruding the backfill around.


Connecting Type:
1.Socket-and-spigot electric fusion jointing
The PE at the contact surface of bell-and spigot is heated and melted by fusion heat, and its molecules bind together to be integrated. The pipes are thus connected after cooling.




2.Advantages of Electric-Fusion connection
The strength of such connection is consistent with pipe strength. It is resistant to root resistance and tension. The bell is integrated with spigot. The operation is simple and convenient.


3.Throttle-type bell-and-spigot connection
According to the patented technology introduced by our factory, the bell mouth or socket is provided with an independent annular ring for mechanical engagement; in addition, seal ring is used for the dual sealing design of zero leakage; the construction is so easy that no third-party equipment is needed; the adaptability of pipe to construction conditions is improved since the construction is available in the case of trenches with accumulated water and rainy days.
