PVC-U spiral noise-abating pipe is designed according to the above principle. The water flow direction and flow forms can be changed to realize noise-abating by changing the structure of the tubing inner wall. This kind of tubing has potential in the indoor drainage market. It has three forms, solid wall spiral noise-abating pipe, with the convex tendon added in the inner wall of the PVC-U building drainage pipe; PVC-U new composite spiral noise-abating drainage pipe, with the convex tendon added in the inner wall of the PVC-U new com-posite drainage pipe; PVC-U double walls hollow inner spiral noise-abating pipe, it makes inner wall of pipe appear spiral convex tendon based on the PVC-U hollow wall pipe.

PVC-U hollow spiral silencer building drainage silent solution

What is PVC-U hollow spiral silencer pipe?

Pvc-u hollow spiral silencing pipe is a kind of noise reduction pipe specially designed for building drainage system, using rigid PVC PVC-U material, combined with spiral diversion structure hollow sound insulation layer technology, effectively reduce drainage noise, suitable for high-rise residential, hotels, hospitals, schools and other places with high requirements for silence.

product advantages

1 . Excellent mute effect

Spiral rib design: the inner wall spiral diversion channel guides the water to rotate and fall, reducing the water impact sound
Hollow sound insulation layer: double tube wall structure, the use of air to block noise transmission, noise reduction of 8 to 15 decibels, measured less than or equal to 45dB
Close to the quiet level of cast iron pipe, but more lightweight, corrosion-resistant, and easy to install

2. High strength and durability

High quality PVC-U material, impact resistance, corrosion resistance, suitable for domestic sewage and chemical drainage environment
Strong bearing capacity, long-term use without deformation, and no leakage

3. Convenient installation and cost saving

Lightweight, convenient handling, and construction reduce labor costs
Using a socket-type adhesive connection, good sealing, and high installation efficiency
Supporting special muffler pipe fittings, 45-degree elbow, tee, etc., to ensure the overall noise reduction effect

4 Environmental Economy

In line with GB/T 5836.1-2018 standard, non-toxic and pollution-free, suitable for civil and commercial buildings
Cost-effective, 30% to 50% lower than cast iron mute pipe cost, lower maintenance costs

Installation Guide

1 Use supporting muffler pipe fittings such as spiral muffler elbow and tee to ensure the noise reduction effect
2 Silencer clamps are set on each layer of the riser to reduce vibration transmission
3. Avoid rigid contact with the wall and adopt a rubber cushion for sound insulation
4 Ensure that the interface is clean during adhesive connection to improve sealing
