Shandong SIFFO Plastic Technology Co., Ltd. has prepared a shipment of HDPE double-wall corrugated pipes with a 300 mm internal diameter and SN8 ring stiffness for a community drainage project in Mongolia. The shipment also includes HDPE pipes intended for the community's water supply network, supporting two essential parts of its infrastructure development.
The dispatch photographs show corrugated pipes being loaded by forklift and stacked on a transport vehicle. This shipment highlights SIFFO's ability to coordinate drainage and water supply pipe orders for overseas community infrastructure projects.
▎Shipment Overview: Community Drainage and Water Supply
The order combines two pipe types with different functions. The double-wall corrugated hdpe pipes are intended for community drainage, while the accompanying HDPE water supply pipes will serve the community’s separate water distribution network.
Manufacturer | Shandong SIFFO Plastic Technology Co., Ltd. |
Destination | Mongolia |

Main drainage application | Community drainage |
Coordinating the two product categories within one shipment helps the buyer organize procurement for the community's drainage and water supply works. Each system still requires its own specifications, connections and installation procedures.
▎Why Use HDPE Double-Wall Corrugated Pipes for Community Drainage?
Community drainage networks need pipes that convey water effectively and perform reliably after burial. HDPE double-wall corrugated pipe combines a corrugated outer wall with a smooth inner wall, giving the two surfaces distinct roles.
Corrugated Outer Wall for Structural Stiffness
The corrugated outer profile provides ring stiffness while making efficient use of material. In a buried installation, the pipe works together with the surrounding soil, bedding and compacted backfill to resist external loads.
This makes installation quality a central part of drainage performance. Correct trench preparation and support around the pipe help control deformation and maintain the intended alignment.
Smooth Inner Wall for Drainage Flow
The smooth internal surface supports water flow through the pipeline. For this shipment, the specified 300 mm internal diameter describes the bore through which drainage water flows. Buyers should distinguish internal diameter from outside diameter when comparing quotations and selecting compatible connections.
The final drainage capacity also depends on pipeline gradient, design flow and network layout. Pipe diameter should therefore be checked against the project's hydraulic design.
Practical Handling for Construction Teams
HDPE structured-wall pipes offer a relatively low weight compared with many conventional concrete drainage pipes of comparable size. This can simplify handling and positioning during construction, depending on pipe length and site conditions.
The shipment photographs capture the loading stage, with the pipes arranged in horizontal layers inside a supporting frame. Careful handling remains necessary to protect pipe ends and connecting surfaces during transport and unloading.
▎SIFFO Manufacturing Capacity for Infrastructure Projects
Shandong SIFFO Plastic Technology Co., Ltd. manufactures plastic piping systems for water supply, drainage, irrigation and industrial applications. The company operates two production bases in Linyi, Shandong, and Nanjing, Jiangsu, covering more than 150,000 m², with total annual production capacity exceeding 450,000 tonnes.
SIFFO's manufacturing resources include eight HDPE double-wall corrugated pipe production lines and 20 HDPE extrusion lines. These capabilities support the supply of different pipe categories for infrastructure projects requiring coordinated procurement.
For overseas buyers, a clear order specification helps align production with construction needs. SIFFO can coordinate pipe dimensions, stiffness or pressure classes, production lengths, compatible fittings, markings, packing and technical documentation according to the agreed order requirements.
▎Request Pipes for Your Community Infrastructure Project
This shipment to Mongolia reflects SIFFO's support for community drainage and water supply development. The combination of 300 mm internal diameter SN8 HDPE double-wall corrugated pipes and accompanying HDPE water supply pipes addresses two separate infrastructure functions within one coordinated order.

SIFFO can help prepare a quotation based on your project specifications.
▎FAQ
What are the specifications of the corrugated pipes shipped to Mongolia?
The drainage pipes have a 300 mm internal diameter and an SN8 ring stiffness classification. They are HDPE double-wall corrugated pipes intended for community drainage.
Does SN8 mean the pipe can carry water at 8 bar?
No. SN8 is a ring stiffness class expressed in kN/m². It describes structural stiffness and should not be interpreted as an internal pressure rating.
What information is needed to request a quotation?
For drainage pipes, provide the diameter basis—internal or external diameter—ring stiffness class, lengths, quantities, joint requirements and installation conditions. For water supply pipes, also specify material grade, pressure rating, applicable standard and any drinking-water approval requirements.
