Hebei Xuanchi Brand PVC Low-Voltage Communication Pipe Manufacturer - 92 Four-Hole PVC Grating Pipe Specifications

1. The nine-hole grille pipe is mainly made of polyvinyl chloride, combined with toughening agents, anti-aging agents, and other auxiliary additives. It integrates the sheath and the inner pipe into one, formed in one molding process, and features an aesthetically pleasing design. It is a type of porous grille pipe.

2. During the production of nine-hole grating pipes, strict quality control is enforced, with a dedicated team of raw material inspectors, production supervisors, physical testers, chemical testers, finished product inspectors in the workshop, and outgoing product inspectors. Product inspections are conducted in strict accordance with the procedures of material inspection, team self-inspection, professional inspection, and outgoing product inspection to ensure that product quality meets national and industry standards.

3. After the production of the 9-hole grille pipe products, they are regularly inspected by the relevant national testing departments annually to ensure the quality meets standards. During the inspection, all product specifications are in compliance. Upon completion, the corresponding test reports are attached. Customers can place orders by phone or fax and then sign the contract.

4. When installing the nine-hole grate pipe, pay attention to the depth (from the pipe top to the road surface), which should not be less than under the pedestrian walkway.0.5MBelow the roadways should not be less than0.7MThe crossing with the tram tracks (from the top of the pipe to the bottom of the track) should not be less than1.00MThe intersection with the railway (from the top of the pipe to the bottom of the track) should not be less than1.5MWhen installing multi-layered 9-hole grid plastic pipes, it is advisable to fill and compact in layers, and the burial depth should be appropriately increased. If these requirements are not met, concrete encasement or protective measures such as steel pipes should be used.
