Beijing four hole grille pipe manufacturer wholesale high-quality PVC grille pipe specifications and models

  The standard length of nine hole threading pipe and nine hole grid pipe is 6m
In the actual construction, the redundant short section cut off at the end can still be used in the appropriate section, with high material utilization rate
Compared with the method of secondary threading sub pipe, the project cost can be reduced to the cost of each sub hole by more than 30%
Nine hole threading pipe, nine hole grid pipe is a kind of porous plastic pipe outside and inside
It integrates the sheath and sub pipe into one, with one-time backlog forming and beautiful shape
It is made of PVC engineering plastics, with high compressive strength, light weight, long service life, smooth inner wall, low friction, convenient construction, resistance to external force and protection of light and cable functions; The inner grid is similar to the square grid shape and has a large effective space, which is convenient for passing through light and cables

As the sheath and the sub pipe are integrated, the laying can be completed at one time
The pipes are connected by socket connection and marked, which is very convenient for construction
As long as the construction unit digs the pipe trench according to the design requirements, the pipe can be laid and the soil can be returned immediately, which greatly shortens the construction period and eliminates the need for secondary threading of sub pipes

The route selection of nine hole threading pipe and nine hole grid pipe is based on the design documents and the documents approved by the urban planning department
The construction team determines the width and depth of the excavated pipeline trench according to the design method of the pipe group
The distance from the top of the pipeline to the pavement is generally 0
7m on the carriageway and 0
5m on the sidewalk
The bottom of the pipe trench shall be flat to avoid too deep excavation and damage to the soil structure
In case of slope, it can be excavated with the terrain, and the clear height of the pipe top shall be maintained; If the route needs to be bent, it should be bent slowly
As long as the pipe can be bent, sharp turns are not allowed, and the construction personnel can control it by themselves

The nine hole threading pipe is adopted
When the nine hole grid pipe is buried, the pipeline trench without special conditions (soft soil) does not need to be used as the foundation, and it is not required to be encapsulated with concrete
In order to prevent excavation in the future, the nine hole threading pipe and the nine hole grid pipe are paved with red bricks after returning soil for 100mm, so as to avoid pipeline damage
Due to the high compressive strength of the nine hole grid pipe, especially when crossing the highway, as long as the construction unit buries the pipe according to the depth required by the design, the pipe is arranged neatly at the bottom of the ditch, and the 20 cm fine soil is backfilled first, and then officially backfilled to prevent large stones from directly pressing on the pipe
If there is no fine soil, it can be paved with sand, which can completely replace the steel pipe method commonly used for highway crossing, which can save a lot of engineering costs and reduce labor intensity at the same time
When the depth cannot be reached when crossing the highway, the concrete encapsulation method can be adopted
When there are stones at the bottom of the ditch, lay a layer of sand about 10 cm thick before laying the pipe
At the end of the hand hole, the sub pipe is equipped with a plug, and the unused hole is blocked with a plug to prevent less mud or foreign matters from blocking the pipe hole

 
Four hole grid tube has strong compatibility and usability
It is suitable for optical cable, cable, coaxial cable, PCM cable, internal communication of enterprises, etc
The raw material of the grid pipe adopts PE (polyethylene) as the main base material
The PVC four hole grid pipe has a large applicable temperature range
The PVC four hole grid pipe has low-temperature resilience, strong compression and impact resistance, acid and alkali resistance and aging resistance
It can be used in cold and tropical areas
PVC four hole grid pipe has been tested by the traffic engineering management center of the Ministry of communications and other cables
PVC four hole grid pipe is widely used in large and medium-sized industries and mines of telecommunications, radio and Television All indexes of PVC meet the requirements of YD / t841-1996 (plastic pipe of underground communication pipeline) technical standard of communication industry

PVC four hole grid pipe is mainly used for optical cable protective sleeve of communication and cable TV, with convenient and fast construction

PVC four hole grid pipe & mdash& mdash; There are nine square, rectangular and other specifications
The length of each pipe is 6m (or as required by users)
The quality of PVC four hole grid pipe (pipe, joint and seal, etc
) meets the Q / kw02-2005 standard, and the annual production capacity of PVC four hole grid pipe is 6 million meters

The four hole grille pipe is made of PVC as the main raw material, with toughening agent, anti aging agent and other auxiliary additives
The sheath and sub tubes are integrated into one body, forming at one time with   appearance
PVC four hole grid pipe is a combination of sheath and sub pipe
It is extruded at one time and has a beautiful shape
P grid pipe is made of PVC engineering plastic
PVC four hole grid pipe has the functions of high compressive strength, light weight, long service life, smooth inner wall, small friction force, convenient construction, resistance to external force and protection of light and cable
The inner hole of PVC four hole grid pipe is similar to square grid type, with large effective space, which is convenient for threading light and cables
