PVC perforated grid pipe four hole grid pipe nine hole grid pipe manufacture

  The obvious feature of nine hole grid tube is that it has nine holes, which are generally divided into two types: large nine holes and small nine holes
Their specifications are 9-33 / 107 and 9-28 / 92
The nine hole grid type square hole pipe integrates the sheath and the sub pipe
It is extruded at one time and has a beautiful shape
It is made of PVC engineering plastics
It has high compressive strength, light weight, long service life, smooth inner wall and small friction force
It is convenient for construction and can resist the influence of external forces and protect the function of light and cable
The inner hole of the nine hole grid pipe is similar to the square grid type, with large effective space, which is convenient for threading light and cables

  The nine hole grid pipe structure is innovative and saves pipe positions
The pipe structure is compact and the road excavation is small, which effectively saves the resources of urban underground pipe positions and has little impact on road traffic and municipal administration
Good toughness, free bending of a 6m pipe with a bending radius of 4m
It can be easily avoided when encountering obstacles or crossing other pipelines during construction
The construction is convenient, labor-saving and time-saving
The sheath is integrated with the sub pipe, and the cable can be threaded without three times of sub pipe laying at one time, avoiding the trouble of deformation and kink of secondary sub pipe, chaotic sequencing and repeated construction; Light weight and convenient handling; The inner wall is smooth and threading is labor-saving
