What is PVC-U electrician casing?
The full name of the PVC-U electrician casing is " PVC-U insulated electrical casing for construction", which is a kind of white or blue or red rigid PVC-U pipe, which is anti-corrosion, anti-leakage, and used for threading. Mainly used in building electrical installation works to protect wire or cable routing, which allows the penetration or replacement of wires or cables. It is formed by twin-screw extrusion with polyvinyl chloride (PVC) resin as the main raw material, supplemented by necessary additives. Mainly used for electrical and communication cable sheathing.
Advantages of PVC-U electrician casing and Tele-pipe
Strong anti-corrosion ability, convenient sticking, low price and hard texture. Suitable for intelligent buildings, indoor lighting buried.
The inside and outside of the pipe are smooth, without ridges, dents, pinholes, and air bubbles. The inner and outer diameters should conform to the national standard, and the thickness of the pipe wall should be uniform.
The insulating conduit accessories and accessories used, such as various lamp head boxes, switch boxes, socket boxes, pipe hoops, adhesives, etc., the length of the casing should be 3 times the outer diameter of the pipe, and the matching flame retardant products should be used.
The wall thickness of the flame-retardant plastic pipe is uniform, and there are no bubbles and deformation of the pipe body; if there is no design requirement for dark laying, medium-sized or larger pipes should be used.
HAILI PVC Electrical Conduit Pipe Quality standards
The pipe is smooth inside and out, without convex and concave depressions, pinholes, bubbles, the inner and outer diameter should meet the national unified standards, and the thickness of the pipe wall should be uniform and consistent.
The insulated conduit accessories and accessories used, such as various lamp head boxes, switch boxes, socket boxes, pipe hoops, adhesives, etc., the length of the casing should meet 3 times the outer diameter of the tube, and use supporting flame retardant products.
The pipe wall of the flame retardant plastic pipe is thin and uniform, and there is no bubble and deformation of the pipe body; Concealed laying should use medium-sized or above catheters if the design is not required.
The connection of the PVC tube is fixed
The conduit into the box must be straight and not inserted obliquely; The length of the sleeve is 1.5 to 3 times the diameter of the pipe; When the conduit sleeve is bonded, the adhesive must be coated with the pipe wall and the end, the end of the tube must be tightly connected and kept at least 15 motionless to ensure that the bond is firm, and the conduit joint and the two ends must be fixed firmly at 50mm.
Application of PVC-U electrician casing and Tele-pipe
PVC-U electrician casing and Tele-pipe are used in normal indoor environment and in places with high temperature, dust, vibration and fire hazard. PVC-U electrician casing and Tele-pipe can also be used in wet places. PVC-U electrician casing and Tele-pipe should not be used in places with extreme humidity, acid, alkali, salt corrosion and explosion hazard. PVC-U electrician casing and Tele-pipe are mainly used for power and communication in buildings and structures, such as indoor threading, in-wall threading, and underground wiring.
The ambient temperature is -15℃～+40℃. Excellent mechanical properties of the threading tube. Excellent corrosion resistance, high compressive strength of threading pipe, working pressure over 2.5Mpa. The surface of the PVC-U electrician casing is smooth, the fluid resistance is small, and it is not fouled and should not breed microorganisms. Small thermal expansion coefficient, no shrinkage deformation. The epoxy plastic coating layer of the casing more effectively solves the corrosion of metal pipes by water, buried and acid, alkali and salt, and the service life can reach more than 50 years.
