Product Introduction:
3SPP ultra-quiet drainage pipe is a polypropylene (PP) ultra-quiet drainage pipe, a new product that replaces u-PVC. This product uses a fully computer-controlled three-layer co-extrusion production process, with both inner and outer layers made from environmentally friendly impact-resistant copolymer polypropylene resin. The middle layer consists of a special noise-reducing sound-absorbing material, providing excellent sound insulation and high-temperature resistance.

DN200*6.5mm average outer diameter: 200.0-200.6mm wall thickness 6.5-7.0mm
Each pipe is 4 meters long.
3SPP silent fittings (elbows, tees, crosses, vent caps, floor drains, pipe clips, S-bends, P-bends, etc.) are also produced.

Product Advantages:
(1) Three main advantages
1. Reduced project cost: In general construction projects, when using flexible cast iron, the budget for drainage can easily exceed one million yuan, with large-scale projects requiring drainage budgets in the hundreds of thousands. However, due to the use of high-strength polypropylene plastic particles and a three-layer co-extruded, one-time forming material, using 3SPP ultra-quiet pipes can reduce drainage project costs by 40%.
2. Saves installation time: The design and installation method of the 3SPP ultra-quiet pipe uses a flexible socket structure and screw connection, making it lightweight and portable. Unlike the flange installation of flexible cast iron, the screw fastening method has received consistent praise from on-site water and electricity installation teams. The installation efficiency can be improved by 70% within the same work group.
3. Excellent noise reduction: The 3SPP ultra-quiet pipe uses flexible connections between pipes and fittings, which not only facilitates quick installation but also effectively prevents the noise generated when water impacts the pipe wall from resonating through to the next pipe or fitting, achieving a soundproofing effect.

(2) Other advantages
1. Strong corrosion resistance, able to withstand long-term exposure to corrosive soil and PH2-PH12 for 95° fluid discharge
2. Smooth inner wall, resulting in lower friction resistance compared to conventional materials;
3. Pipes and fittings do not rust, preventing internal erosion and shrinkage;
4. The building's exterior walls will not be polluted by rusting pipes, preserving the building's value;
5. A wide variety of pipe fittings are available to meet various design and installation requirements;
6. Easy installation, requiring no regular maintenance;
7. Weighs one-fifth of cast iron pipes, making it easy to transport and handle;
8. Odorless, tasteless, and non-toxic;
9. Resistant to termites and weathering, and not affected by bacteria;
10. Under normal usage conditions, the lifespan can reach over 60 years.

Installation Method:
(1) Socket-type PP ultra-quiet drainage pipe installation points
When installing the pipeline, use a special cutting knife to cut, ensuring the cross-section is perpendicular to the axis. The distance between two socket-type flexible connection points should not exceed 3m. Length adjustments can be compensated through the depth of the socket, but the length that the pipe can be pulled out after inserting into the fitting should not exceed 8mm in summer and 12mm in winter.

(2) Socket plus screw-type PP ultra-quiet drainage pipe installation points
1. Use a specialized pipe cutting machine (cutter or cutting knife) to cut the pipe, ensuring the pipe end is perpendicular to the pipe axis.
2. Sequentially fit the threaded ring, snap ring, and sealing ring onto the pipe being connected.
3. Insert the pipe end into the inner groove of the fitting (a lubricant can be evenly applied to the pipe end).
4. Push the pipe until it reaches the bottom of the fitting's inner groove (4mm), and then start tightening the threaded ring to achieve a sealed connection.
