Upvc Double Walled Silencing Pipe
The UPVC Double Walled Silencing Pipe is a drainage and vent component manufactured from unplasticized polyvinyl chloride. It is offered in diameters of 50 mm, 75 mm, 110 mm and 160 mm, with wall thicknesses ranging from 2.0 mm to 4.0 mm and lengths of 4 m, 6 m or custom cut‑to‑size. The pipe follows GB/T18477.3‑2009 and ISO 9001:2008 standards and is supplied in a white colour with a double‑walled hollow spiral structure designed for sound dampening.
The material is a rigid PVC compound that resists ageing and maintains a density of 1.3 - 1.5 g/cm³, giving a service life of around 50 years. Typical industry practice for similar silencing pipes includes a pressure rating of PN 1.0 and an SDR‑11 design, which provide reliable performance in residential and commercial wastewater systems. The double‑wall design creates an inner spiral flow guide and a porous honey‑comb core that reduces water noise by about 13 dB(A) under normal flow conditions.
These pipes are used in sewage management, building drainage and HVAC silent vent installations, and are purchased by contractors, building developers and municipal utilities. Suppliers can provide standard fittings such as elbows, tees, crosses and couplings, all joined by solvent‑based glue. The factory reports a monthly capacity of 500 000 m, ships from the port of Dalian and offers lead times of five days for orders up to 5 000 m, ten days for 5 001‑10 000 m, with larger quantities negotiable.

Sourcing UPVC Double Walled Silencing Pipe from Liaoning Jianxi Science And Technology Co., Ltd - China Import Guide
Before placing an order, verify the supplier’s current ISO 9001:2008 certificate, request a product data sheet that confirms the exact diameter, thickness and length you need, and ask for a sample if possible. Confirm that the pipe colour, wall structure and double‑wall design match the specifications required for your project, and ensure that any required CE or other export certifications are available.
Logistics for this product typically involve shipment from the port of Dalian. Lead times vary from five to ten days depending on order volume, with larger quantities negotiated separately. Discuss Incoterms such as FOB Dalian or CIF Shanghai and clarify payment terms, as the supplier does not publish them publicly. Align your freight forwarder’s schedule with the supplier’s production capacity to avoid delays.
Arrange a third‑party inspection before loading to check dimensions, wall thickness, material density and surface finish. Request the supplier’s test reports for sound attenuation and pressure rating, and ensure that the export documentation includes a full packing list, commercial invoice and certificate of origin. These steps help guarantee that the delivered pipe meets the technical and regulatory requirements of your market.
