PVC silencing drainage pipe

Product overview
Ordinary smooth outer wall and inner wall hard PVC drainage pipe, in the drainage process produced higher noise, and the inner wall of the spiral rib structure of rigid PVC pipe in drainage can significantly reduce the noise. The principle is that the fluid flow in the tube of the structure reduces the impact on the inner wall of the tube, and can smooth the air flow out of the fluid.. Therefore, in doing with a silencer good indoor drainage tube. The structure of this tube is characterized by a triangular shaped spiral rib with a section of its inner wall, and the rib height is generally 3mm, and the distance of the 50mm is circled continuously.current product specifications, 75mm, wall thickness 2.3mm, wall thickness 110mm, wall thickness 3.3mm two kinds of main. The spiral rib of this tube is not an accessory, and it is formed at the same time as the tube wall.. Product advantages The hardness and tensile strength of pipe surface are excellent, and the safety coefficient of pipeline is high.. Good anti-aging, normal service life of up to 50 years. The pipeline has good corrosion resistance for inorganic acid, alkali and salt, and can be used for industrial sewage discharge and transportation.. The friction coefficient of the pipeline is small, the water flow is smooth, and the maintenance is less.. The material oxygen index is high, and has the self extinguishing property.. The expansion coefficient of the pipeline is small, and the temperature of 0.07mm/m is small.. The heat conduction coefficient and the elastic modulus are small, compared with the cast iron drain pipe, the freezing resistance is excellent Pipe, pipe fittings can be used bonding, construction method is simple, easy operation, high efficiency of installation. Application domain Industrial and civil construction indoor off-road engineering continuous discharge of sewage temperature not more than 40 DEG C, momentarily discharged sewage temperature not greater than 80 DEG C; and for the pipe can not afford the corrosive effect of industrial waste water can be used.
