Inner diameter 100 150175200mpp double wall bellows factory direct sales

IFB power enhanced bellows, also known as modified polyvinyl chloride (MPP) double wall bellows
Modified polyvinyl chloride (MPP) double wall corrugated pipe is a new type of plastic pipe with double wall corrugated structure, which is made of polypropylene as the main material and blending modification as the main material
It is made through advanced extrusion and composite reinforcement modification with special formula and processing technology
The utility model has the advantages of novel structure, high strength, good temperature resistance, simple construction and cost saving
As a new product in the industry of power pipeline for excavation, it solves the difficulties in process forming and material composite reinforcement and modification, and creatively designs a novel product structure and button connection mode
Therefore, this technology has broad application prospects

Product features
  l   High cost performance, saving 40% - 70% material compared with MPP solid wall pipe with ring stiffness requirements of the same specification

  l   Good compressive rigidity, special double wall structure design and high elastic modulus materials make it have high ring stiffness

  l   The pipe construction can be directly backfilled with pipe pillow and fine sand without cement encapsulation, which can greatly reduce the construction dust pollution and reduce the construction cost

  l   It is smooth and easy to thread the cable
Silicone additives are added to the raw materials of the inner wall to reduce the friction coefficient of the inner wall, reduce the cable threading resistance and reduce the construction difficulty

  l   Heat resistant, Vicat softening temperature is above 135 ℃, and good external pressure resistance can still be maintained at higher temperature
High voltage power line cable can still be used when heating

  l   Polypropylene modified with high modulus and high elasticity has good impact resistance and low temperature resistance

  l   Insulation: it has good insulation performance and meets the requirements for safe use of high-voltage power

  l   It has the advantages of good acid, alkali, salt corrosion and aging resistance, and its buried life is longer than 50 years

  l   The connection has excellent sealing performance
It is connected with a special clamp and sealed with an elastic sealing ring
There is no welding seam or flash of the solid wall pipe, and the dragging cable will not be scratched or cut

  l   Superior sanitation and environmental protection performance, environmental protection additives are added to raw materials, pipe waste can be recycled, and there is no pollution in the production and recycling process

application area
MPP double wall corrugated pipe is mainly used in urban and rural open excavation cable duct works for high-voltage transmission line cables above 10kV
The ordinary type is suitable for laying under the green belt, and the standard type is suitable for laying on the slow lane; If the requirements for seismic resistance and compression resistance are harsh or replace the steel pipe, the reinforced (sn50) special customized products shall be selected
