The PVC trough pipe line and storage

the PVC trough go line construction way

play line precision positioning: clear out the installation location, according to the design drawings from the beginning to the end, Home after arterial branch) Looking for a good horizontal or vertical, good distribution circuit to measure and cables in accordance with the specific construction drawings, marked much of a hole, where is the open hole and horizontal cable and flat cable and the trend of the number and size of the PVC trough.
needed materials should level off, without obvious distortions. After cutting length error should be within 5 mm, wound place should be without flash, burr phenomenon; Install strong, make sure not oblique; Fixed point interval is usually not more than 1 - 1. 5 mm, in the junction box, box, cabinet, corner, corner and jump connection head three end should be set up within 500 fixed points, and the specifications of the plastic bolt is usually not less than 8 mm, self tapping screw 4 mm * 30 mm.
the PVC trough pipe installation required: PVC trough pipe level off is smooth, no deformation, no burr inner wall, complete all kinds of accessories, PVC trough pipe connection level off is smooth, the connection mouth level off, smooth after installation slot cover, without raised feet, the concrete position of the line must be correct, the PVC trough all the angular point must be connected, as a continuous conductor, be sure to do the overall earthing protection, the design of the PVC trough pipe must be accord with 'code for fire protection design of tall buildings' ( GB50045 - 95). The requirements of the departments concerned.
the PVC trough connection body contains two lateral dampers.
the PVC body section of u-shaped slot connections, PVC U bottom line slot connection body set up in at least two orifice, the PVC trough connecting wiring in the tube and plug in a small specifications according to the screw small compared with the specifications of the wiring in the tube surface.
line slot on the left and right sides of the connecting plate symmetry about set up before and after the two bright fixed hole. The line slot directly connecting plate Y axis like around before and after setting up a fixed orifice.
PVC slot connection body contains two side baffles, a blank and two curved plate, two side gears slabs said adding vertical connect with blank side of the blank, two curved plate respectively with two side close to variable diameter solid on both sides of the side of the vertical connect closely, blank set up at least two wire inside hole.





PVC trough maintenance way PVC trough pipe pressure should be hidden, usually work pressure curing pressure, until the hidden layer to allow the pressure intensity.
because the PVC trough a soft texture, high itself without the impact toughness of seamless steel tube, so must resolutely put an end to physical damage, installation of pipe after it is prohibited to knock, touch, hit, pressure, to improve the cover before the hidden security measures, which is located inside the tube well pipe before is not fully enclosed some countermeasures should be adopted to avoid the brick, dirt on fall will be crushed.
because consist of PVC trough, to take precautions against chemical damage, which is very easy to ignore in the construction site, installed in the outdoor or the sun line, to pack the protective layer of brunet attune, avoid the sun for pipe lead to chemical damage.
