Steel Wire Mesh Reinforced Composite HDPE Pipe (SRTP) is a new environment friendly pipe in which high strength steel wire in a winding shape is used as skeleton and high density polyethylene is used as the substrate for internal and extermal layers. Thermosol is used to bond them together while the layers are continuously extruded and haped. Suc pipe maintains good pressure withstanding of steel pipe while additionally has the good hyglenic nature of plastic pipe and its strong points of easy laying,reliability in tenchnolog and long service life.
Hence it can be widely used in municipal water supply-drainag system,fire protection systems in chemical industry,petroleum industry,medicine industry,etc.in large quantity.
GOOD RESISTANCE TO RAPID CRACK GROWTH
The rapid cracking of the pipeline may instantly cause a major accident of damage to the pipeline of more than ten meters or even thousands of meters. Polyethylene has excellent resistance to rapid crack growth. At the same time, it also has good resistance to scratches and slow crack growth. It is a kind of Safe Plumbing Products.
DURABLE and ANTI-CORROSION
Polyethylene is an inert material, except for a few strong oxidants, it can resist various chemical media and microbial erosion, no electrochemical corrosion, no need for anti-corrosion coating, and the designed service life is 50 years
SOFT and BENDABLE
Good flexibility enables small-diameter polypipes to be coiled without pipe connections, reducing material costs, and is used for non-excavation construction. The direction of the pipeline can be changed according to the requirements of the construction method.
EASY MOVE and INSTALL
Low density (about 0.94-0.965g/cm3), light weight, easier to transport and install than unimpeded steel pipes or cast iron pipes, reducing construction labor intensity and engineering installation costs.
HIGH TOUGHNESS
The elongation at break generally exceeds 500%. It has strong applicability to uneven settlement when shutting down, and has excellent seismic performance. It can be applied to harsh construction conditions such as uneven foundation and dislocation.
SANITATION and ENVIRONMENTAL PROTECTION,HIGH CONVEYING EFFICIENCY
Hygiene and environmental protection, compound domestic drinking water transmission and distribution equipment requirements. The inner and outer surfaces of polyethylene pipes have high smoothness, high transmission efficiency, and can maintain excellent hydraulic performance during the service life.
RELIABLE CONNECTION
Hot-melt, electro-fusion connection ensures the identity of the interface material, structure and the pipe body itself, and the tensile strength and burst strength of the interface are higher than the pipe body. The co-extrude interface is clear, long-term sunshine is not easy to fade, and the depth of embedding in the pipe wall thickness is small, so as to avoid welding defects.
1: Higher strength resistance and creep resistance.
2: Excellent stiffness, impact resistance. Low linear expansion coefficient.
3: Smooth inner wall, won't covered with dirt. Low flow resistance, high flow capacity.
4: Both the inner and outer wall are made of plastic, lead the pipe and fittings owns good corrosion resistance.
5: Light weight, easy to transport.
6: Use electro-fusion joint, no leakage in the joint, fast and easy installation.
7: The product is composited with steel wire and plastic, overcome the fast stress crack of plastic pipe.
8: Good abrasion resistance. The product can work for more than 50 years under normal use.

Note:
1: The pipe wall thickness is base on the GB/T 32439-2015 or specified EN/ISO standards
2: Nominal pressure based on water medium temperature ≤20ºC. It should be adjust when the temperature of the medium change.
3: Colour of the pipe is black ,others should be negotiate.
4: Application:water,Corrosive liquid,pulp.
LANGBOONE PE soild pipe and composite pipes can be joined by a variesty of methods includng mechanical joints and a range of thermal fusion procedures,the main methods are Butt Fusion,Electrofuion joint,socket fusion joint,flange adaptor joint and compression joint.
